Edible oils and fats are a group of organic substances that are extracted from various plants and animals. They are commonly used in cooking and food production, and have a variety of other applications as well. Here's a detailed breakdown: Definition of Edible Oils and Fats Edible Oils: These are fats that are liquid at room temperature. They are extracted from various plants and are primarily used in cooking, baking, and as salad dressings. Common examples include olive oil, sunflower oil, and canola oil. Edible Fats: These are usually solid or semi-solid at room temperature and are often derived from animals. Butter and lard are common examples. Some plant-based fats like coconut oil and palm oil also fall under this category. World Edible Oil Production Data (as of 2023) Global production of edible oils has been increasing over the years due to growing demand. The major contributors to the world production of edible oils are palm oil, soybean oil, and canola oil. Asia, particularly countries like Indonesia and Malaysia, are the leading producers of palm oil. The United States, Brazil, and Argentina are key producers of soybean oil. The production numbers are influenced by factors like agricultural practices, climate change, and global market demands. Common Sources of Edible Oil 1.Palm Oil: Extracted from the fruit of oil palms; primarily used in food products, detergents, cosmetics, and biofuels. 2.Soybean Oil: Derived from soybeans; widely used in cooking and industrial applications. 3.Canola Oil: Obtained from the seeds of the canola plant; known for its low saturated fat content. 4.Olive Oil: Extracted from olives; highly valued for its flavor and health benefits, particularly in Mediterranean cuisine. 5.Sunflower Oil: Comes from sunflower seeds; appreciated for its light taste and high vitamin E content. 6.Coconut Oil: Sourced from the meat of coconuts; used in cooking, cosmetics, and even in medicinal products. 7.Corn Oil: Derived from the germ of corn kernels; often used in frying due to its high smoke point. Each of these oils has its own unique properties and nutritional values, making them suitable for different culinary and industrial applications. The choice of oil often depends on factors such as flavor, smoking point, and  Plants used to produce edible products: Soybean, cottonseed, sunflower seed, safflower seed, corn germ, peanut, olive, rice bran, rapeseed, canola, coconut, palm fruit, and carob.  Animal sources and animal fat products: Cattle, sheep, pigs, fish Butter, lard, tallow, whale oil and fish oil. 6 7 8 9 Vegetable oils are primarily extracted from beans or seeds. The extraction process yields two valuable products: oil and a protein-rich meal. Methods of extraction include mechanical pressing and solvent extraction. Oil Extraction Methods 1.Pressing: A mechanical process used to squeeze oil out of the seeds or soft fruit endosperm. This method is commonly used for oils such as olive and palm. 2.Solvent Extraction: A chemical process that uses a solvent to separate oil from the seed meal. This is often used in combination with pressing for higher oil yield. Oil Yields from Various Sources The amount of oil obtained varies significantly among different plant sources: Soybean: Yields about 18.3% oil. Rapeseed: Known for a high oil yield of 38.6%. Sunflower: Produces a substantial 40.9% oil yield. Groundnut (Peanut): Also provides a significant yield of 40.3%. Cottonseed: Offers a lower yield of 15.1%. Coconut: Remarkably high oil content at 62.4%. Palm Kernel: Contains about 44.6% oil. Sesame: Notable for its 42.4% oil yield. Linseed: Yields a moderate 33.5% oil. Palm Fruit: Generally yields between 45–50% oil. Olive: Produces oil in the range of 25–30%. Corn: Has a relatively low oil yield of about 5%. Fatty Acid Structures in Edible Oils Saturated Fatty Acids: Arachidic Acid: A long-chain fatty acid with 20 carbon atoms, no double bonds. Stearic Acid: Contains 18 carbon atoms, no double bonds, commonly found in animal fats. Palmitic Acid: Comprises 16 carbon atoms, no double bonds, present in palm oil and meat. Monounsaturated Fatty Acid: Erucic Acid: A 22-carbon monounsaturated fatty acid with one double bond. Oleic Acid: An 18-carbon monounsaturated fatty acid with one double bond, prevalent in olive oil. Polyunsaturated Fatty Acids: Arachidonic Acid: A 20-carbon polyunsaturated fatty acid with four double bonds, important for inflammatory and immune responses. Linoleic Acid: An essential 18-carbon fatty acid with two double bonds, found in many vegetable oils. Linolenic Acid: An 18-carbon fatty acid with three double bonds, an essential omega-3 fatty acid. The smoke point of an oil is the temperature at which it begins to smoke and break down. It is a key factor in cooking and food preparation for several reasons: 1.Flavor and Nutritional Quality: When an oil reaches its smoke point, it can begin to lose its flavor and nutritional value. The fatty acids in the oil can start to oxidize, which may produce harmful free radicals. 2.Cooking Performance: Oils with higher smoke points are more stable at high temperatures, making them suitable for high-heat cooking methods like frying, searing, and sautéing. Oils with lower smoke points are better suited to low-heat cooking, like simmering, or for use in salad dressings and marinades. 3.Chemical Stability: The smoke point is also an indicator of the oil's chemical stability. More stable oils, which are typically those higher in saturated and monounsaturated fats, can resist oxidative damage for longer periods when heated. 4.Health Concerns: The breakdown products of oils at high temperatures can include trans fats and other compounds that are detrimental to health. Therefore, cooking with an oil below its smoke point can help maintain a Fatty Acid Composition and 1. Higher in saturated fats 4. Smoke point: 437°F Smoke Point of Vegetable (25.900%).

(238°C), suitable for 1.Relative Density (20°C): 1. Relative density also helps in the identification of the oil because each oil has a specific density range. 2.Refractive Index (at 20°C): 1.The refractive index indicates how light bends or refracts as it passes through the oil. This parameter is used to determine the purity of the oil and to detect if any adulteration has occurred. 1.Saponification Number (mg KOH/g oil): 1.This number indicates the amount of potassium hydroxide in milligrams that is required to saponify one gram of oil. It helps identify the average molecular weight (or chain length) of the fatty acids in the oil. A high saponification number suggests shorter chain fatty acids, while a lower number indicates the presence of longer chain fatty acids. 2.Iodine Value (WIJS): 1.The iodine value measures the degree of unsaturation (the number of double bonds) in the fat. Oils with higher iodine values have more double bonds, which means they are more unsaturated. This property is important for understanding the oil's stability, shelf life, and suitability for various culinary uses. More unsaturated oils tend to be less stable and can go rancid more quickly. 3.Non-Saponifiable Matter (mg/kg): 1.Non-saponifiable matter refers to the components in the oil that cannot be saponified, or converted into soap, by treatment with alkali. These substances, which include sterols, tocopherols (vitamin E), pigments, and hydrocarbons, are important for the nutritional and sensory properties of the oil. A lower level of non-saponifiable matter is usually preferred for refining and consumption purposes 1.Volatile Matter (105°C): This measures the percentage of substances in the oil that can evaporate at 105°C. A low percentage indicates higher purity and better quality. 2.Insoluble Impurities: Refers to the portion of the oil that does not dissolve; it includes particles or sediments. High-quality oils have very few insoluble impurities. 3.Soap Content: This is the amount of soap-like substances in the oil, which can form during the refining process. In refined oils, this should be very low, but in cold-pressed and natural oils, a certain amount is acceptable as it indicates minimal processing. 4.Acid Number (Acidity): It measures the free fatty acid content of the oil, expressed as milligrams of potassium hydroxide (KOH) needed to neutralize the free fatty acids in one gram of oil. Lower numbers indicate better quality for refined oils, while slightly higher values are permissible in cold-pressed and natural oils due to less processing. Sunflower Seed Oil Overview: Sunflower oil is derived from the seeds of the sunflower plant. It is known for being light in taste and appearance. Provides a high amount of Vitamin E compared to other vegetable oils. Contains a healthy mix of monounsaturated and polyunsaturated fats, with low levels of saturated fats. Types of Sunflower Oil: 1.Mid-Oleic Sunflower Oil: This is a standard type of sunflower oil with moderate levels of oleic acid. It's a versatile oil suitable for a wide range of cooking applications. 2.Linoleic Sunflower Oil: This type has high levels of linoleic acid, an essential polyunsaturated omega-6 fatty acid. It's known for its health benefits but is less stable when heated due to higher polyunsaturated fat content. 3.High Oleic Sunflower Oil: Contains high levels of oleic acid, a monounsaturated fat that provides better stability and shelf life. It is particularly good for high-heat cooking and industrial food processing. Properties: All three types of sunflower oil are developed through standard breeding techniques. They have varying levels of oleic acid which influence their stability and suitability for different cooking methods. Each type offers unique properties that can cater  High oleic sunflower oil High oleic sunflower oil is very high in oleic (monounsaturated) acid. High oleic sunflower oil is usually defined as having a minimum 80 percent oleic acid. The oil provides excellent stability without hydrogenation. High oleic sunflower oil offers a trans free oil solution for some customers. The oil has many uses including bakery applications, spray coating oils for cereal, crackers and dried fruit; it is used in non-dairy creamers, many types of frying and other uses. COTTONSEED OIL Source and Extraction: Cottonseed oil is derived from the seeds of the cotton plant, a major crop grown around the world. The extraction process of cottonseed oil typically involves pressing the seeds or using solvent extraction methods. Composition: It is predominantly an unsaturated oil, with about 70% of its composition being unsaturated fats. The unsaturated content is comprised of approximately 18% monounsaturated fats, primarily in the form of oleic acid. The remaining 52% consists of Physical properties Once processed, cottonseed oil has a mild taste and appears generally clear with a light golden color, the amount of color depending on the amount of refining. It has a relatively high smoke point as a frying medium. Like other long-chain fatty acid oils, cottonseed oil has a smoke point of about (232 °C) and is high in tocopherols, which also contribute its stability, giving products that contain it a long shelf life, hence manufacturers' proclivity to use it in packaged goods. Use in food Cottonseed oil has traditionally been used in foods such as potato chips and is a primary ingredient in the shortening products. But since it is significantly less expensive than olive oil or canola oil, cottonseed has started to creep into a much wider range of processed foods, including cereals, breads and snack foods. Products that say "may contain one or more of these oils" and list cottonseed, virtually always contain it. SOYBEAN OIL Soybean composition Protein 40 % Oil (dry basis) 20 % Cellulose and hemicellulose 17 % Sugars 7% Crude fiber 5% Ash (dry basis) 6 % Soybean is the dominant oilseed produced in the world, due to its favorable agronomic characteristics, its high-quality protein, and its valuable edible oil. It contributes over a half of all oilseeds produced worldwide Applications and Importance Culinary Use: Soybean oil is a staple in both household and commercial cooking due to its neutral flavor and high smoke point. Processed Foods: Its versatility makes it a common ingredient in processed foods, including baked goods, salad dressings, and snack foods. Industrial Use: Hydrogenated soybean oil is used in non-food products such as candles, lubricants, and plastics. Animal Feed: The byproduct, soybean meal, is a cost-effective and protein-rich feed for livestock. The production of soybean oil is a vital process in the agricultural and food industries, reflecting the global demand for both its edible oil and its role in animal nutrition. Soybean Oil Production Process 1. Cleaning and Cracking: Cleaning: The harvested soybeans are cleaned to remove dirt, stones, and other impurities. The flakes undergo solvent extraction, usually Cracking: The cleaned soybeans are then with a hydrocarbon solvent like hexane, to dissolve cracked into smaller pieces to facilitate oil the oil. extraction.

Rolling into Flakes: The heated soybeans are rolled into thin flakes. This increases the surface area, making the extraction of oil more efficient. RAPESEED OIL (CANOLA OIL) kolza tohumu Source: Derived from the seeds of the canola plant (Brassica napus and Brassica rapa). Developed through traditional plant breeding from rapeseed to have low erucic acid and glucosinolate levels. Environmental Aspect: Canola plants are a sustainable crop, often part of crop rotation to improve soil health. Uses: The growing process uses fewer pesticides compared to other oilseed Culinary: High smoke point makes it suitable for frying, baking, and crops. salad dressings. Industrial: Used in the production of biofuels, lubricants, and plastics. Health Products: Its oil is included in margarine and some omega-3 enriched foods.

CORN OIL Corn Oil in Industry and Nutrition Industrial Uses: Biodiesel: Used as a biofuel component due to its renewable nature and combustion efficiency. Manufacturing: Integral in producing soaps, paints, rust preventatives, inks, and textiles. Pharmaceuticals: Acts as a carrier for drug molecules, aiding in the delivery of pharmaceuticals. Nutritional Profile: Composition: Refined corn oil is 99% triglyceride, with a fatty acid composition of 59% polyunsaturated, 24% monounsaturated, and 13% saturated. Health Benefits: The high content of polyunsaturated fats can contribute to lowering cholesterol levels when used in moderation. HAZELNUT OIL HAZELNUT  Hazelnuts are rich in protein and unsaturated fat. Moreover, they contain significant amounts of thiamine and vitamin B6, as well as smaller amounts of other B vitamins.  Hazelnut oil, pressed from hazelnuts, is strongly flavoured and used as a cooking oil.  In the fatty acid composition of hazelnut oil, there is around 71-91% of oleic acid.  Hazelnut oil also contains linoleic acid at a rate of around 2-21%.  Hazelnut oil is rich in calcium and vitamin E. OLIVE OIL The Olive Tree (Olea europaea)Origin: Native to the eastern Mediterranean region. Significance: Culturally and agriculturally important, especially for olive oil production. Cultural and Economic Importance A staple in Mediterranean diets; significant in culinary, medicinal, and cosmetic uses. Types of Olive Oil Extra virgin, virgin, and refined olive oils – differing in production methods and quality. Definition of Extra Virgin Olive Oil (EVOO): EVOO is the highest quality olive oil, characterized by perfect flavor and aroma, free of defects, and produced entirely by mechanical means without the use of any solvents, and under temperatures that will not degrade the oil (below 27°C). Production Process 1.Harvesting: 1.EVOO requires careful handling of the olives. Typically, they are handpicked to prevent bruising and damage that can lead to oxidation and fermentation, which degrade quality. 2.Transport and Storage: 1.After harvesting, olives are transported in ventilated crates and processed quickly to minimize spoilage and fermentation. 3.Cleaning and Washing: 1.Olives are cleaned to remove leaves, twigs, and other debris, then washed to remove dirt and contaminants. 4.Crushing: 1.The olives, including pits, skins, and flesh, are crushed to create a paste, traditionally with stone mills but increasingly with steel drum crushers. 5.Malaxation: 1.The paste is slowly churned or mixed to allow the small oil droplets to agglomerate, enhancing oil extraction. 6.Extraction: 1.Modern methods use a centrifuge to separate oil from the water and solids. The process is temperature-controlled to protect the oil’s quality. 7.Decantation: 1.The oil is left to settle in tanks to naturally separate from any remaining water (vegetation water) and solids without filtration. 8.Filtration (Optional): 1.Some producers choose to filter the oil to remove any remaining Extraction: Modern methods use a centrifuge to separate oil from the water and solids. The process is temperature-controlled to protect the oil’s quality Decantation: The oil is left to settle in tanks to naturally separate from any remaining water (vegetation water) and solids without filtration. The two-phase and three-phase systems refer to the methods used in the centrifugation process during the production of olive oil. They are both modern methods for separating the oil from the olive paste (which is obtained after crushing the olives), but they have some differences: Two-Phase System: 1.Operation: In the two-phase system, the olive paste is separated into two phases - the oil and a wet paste, which is a mixture of water and solids. 2.Water Usage: This system uses less water compared to the three- phase system, or no added water at all, which is why it's called a "two- phase" system. 3.Waste Product: The byproduct is a semi-solid waste, which has a higher moisture content. This can be an advantage as the waste is easier to manage and can sometimes be used as fertilizer or in biogas production due to its high organic content. 4.Energy Consumption: Generally, two-phase systems consume less energy because there is no need to heat additional water. 5.Oil Yield: The yield may be slightly lower, but the oil produced often contains more polyphenols and other water-soluble substances, which can give the oil additional health benefits and a longer shelf life. 6.Environmental Impact: Less wastewater is produced, making the Three-Phase System: 1.Operation: The three-phase system separates the olive paste into three phases: oil, water, and solid waste. 2.Water Usage: It requires a significant amount of water to facilitate the separation process, which is why there are three phases (oil, water, and solids). 3.Waste Product: The byproduct is a drier pomace and wastewater known as "alpechin" or "olive mill wastewater" (OMW). The OMW is often considered a pollutant due to its complex chemical composition and requires proper treatment before disposal. 4.Energy Consumption: This system may use more energy due to the need to add and heat water during the process. 5.Oil Yield: The three-phase system generally has a higher yield of oil compared to the two-phase system. 6.Environmental Impact: Produces a large volume of wastewater, which presents greater environmental challenges. Two-Phase: Less water and energy use, lower yields, more phenols in the oil, wetter waste product, environmentally friendlier. Three-Phase: Higher water and energy use, higher yields, drier waste, environmental concerns due to wastewater. In choosing between the two, producers must consider factors like water availability, environmental regulations, the desired quality of the oil, and the handling of byproducts. Some regions prefer the two-phase system due to stricter environmental laws and a focus on higher quality, while others may opt for the three-phase system for its efficiency and higher yield. Quality and Standards Chemical Standards: Acidity level below 0.8%. Peroxide value below 20 milliequivalents O2 per kg. Absence of sensory defects, as determined by a trained tasting panel. Sensory Standards: EVOO should have a fruity taste characteristic of fresh olives and can have varying degrees of bitterness and pungency. Pomace Oil The extraction of pomace oil from the solid byproduct of olive oil production, known as pomace or olive cake, is a process that allows for the recovery of residual oil remaining in the olive husks after the primary extraction process. The process can be summarized as follows: 1. Composition of Pomace Pomace is composed of the solid remains of olives, including the skin, pulp residue, and olive pits, after the first extraction of olive oil. It contains a certain percentage of oil, moisture, and organic matter. 2. Residual Oil Content Pressure Systems: Pomace from traditional pressure systems tends to have a higher oil residue, typically around 6–8%. Pomace is transported to specialized plants for further processing. The high moisture content of pomace (25–58%) makes transportation costly. 4. Solvent Extraction Hexane Extraction: The residual oil is extracted from the pomace using an organic solvent, typically hexane, which dissolves the oil. Separation: After the oil is dissolved, the hexane is then removed by evaporation, leaving behind the crude pomace oil. 5. Refinement of Crude Pomace Oil Neutralization Bleaching: Deodorization: 6. Designation and Use Distinct Product: Due to its different chemical composition, pomace oil is considered a separate product from virgin olive oils. Applications: After refinement, pomace oil is suitable for consumption and is often used for cooking due to its higher smoke point compared to extra virgin olive oils. Palm oil is a highly versatile and efficient vegetable oil derived from the fruit of the oil palm trees, primarily the African oil palm Elaeis guineensis, and to a lesser extent from the American oil palm Elaeis oleifera and the maripa palm Attalea maripa. These oil palms are native to Africa but were brought to Southeast Asia in the late 19th century and have become extensively cultivated there. Today, palm oil is produced in tropical regions of Africa, Southeast Asia, and Latin America, with Indonesia and Malaysia being the world's largest producers. As a crop, oil palms are highly productive, offering a greater yield per hectare than any other major oilseed crop. This efficiency, combined with the oil's stability in heat and suitability for a wide range of temperatures, has led to palm oil's dominance in the global vegetable oil market. It is estimated that palm oil constitutes nearly one-third of the world's vegetable oil consumption. The importance of palm oil can be seen in its pervasive use across various industries. In the food industry, it's a key ingredient in products ranging from margarine and chocolate to ice cream and baked goods, favored for its lack of trans fats and its semi-solid nature at room temperature, which can enhance the texture and shelf life of food products. Beyond food, palm oil is also an essential component in the production of personal care items, detergents, and increasingly as a biofuel. However, the production of palm oil has been associated with significant environmental and social challenges, such as deforestation, loss of biodiversity, and issues related to land rights and indigenous communities. These concerns have led to the creation of sustainable palm oil certification programs, aiming to minimize the negative impacts and ensure that production meets Palm oil, obtained from the mesocarp of the oil palm fruit, is a unique vegetable oil in that it naturally contains a high proportion of saturated fatty acids, which are usually solid at room temperature, and unsaturated fatty acids, which are typically liquid. Upon processing, palm oil can be fractionated into different components based on their melting points, which are then used for various applications in food products, industrial applications, and even in the production of biofuels. The main fractions obtained from palm oil are: 1.Palm Olein 4.Super Olein 2.Palm Stearin 5.Palm Kernel Oil 3.Palm Mid 6.Palm Kernel Fraction (PMF) Stearin 7.Palm Kernel Olein Palm Olein Description: This is the liquid fraction obtained when palm oil is fractionated. It has a lower melting point. Properties: Palm olein is rich in unsaturated fats, particularly oleic acid. Uses: It is commonly used for cooking and frying due to its good oxidative stability. It's also found in food products such as margarine and shortening. Palm Stearin Description: The solid fraction that results from fractionation, palm stearin has a higher melting point. Properties: It contains a higher proportion of saturated fats, which makes it more solid and stable. Uses: Due to its solid state at room temperature, it's often used in the manufacture of products that require a higher melting point like margarine, shortenings for bakery, and non-dairy creamers. It's also used in non-food applications such as soaps and candles. Palm Mid Fraction (PMF) Description: This is an intermediate fraction with a melting point between that of palm olein and palm stearin. It's obtained through further fractionation of palm stearin. Properties: PMF has a balanced content of unsaturated and saturated fatty acids. Uses: It's particularly valued in the confectionery industry for coatings and fillings due to its smooth melting profile, which is similar to cocoa butter. Super Olein Description: This is a more fluid version of palm olein, obtained by further fractionation. Properties: It has a lower cloud point compared to regular palm olein, which means it remains clear at lower temperatures. Uses: It's especially useful in colder climates where regular Palm Kernel Oil and its Fractions Description: Derived from the kernel of the oil palm fruit, palm kernel oil is also fractionated into palm kernel olein (liquid) and palm kernel stearin (solid). Properties: Palm kernel oil and its fractions have properties and uses similar to those of coconut oil, being high in lauric acid. Uses: Widely used in the manufacture of cosmetics, soaps, and detergents, as well as in food applications. The process of fractionation allows for the wide use of palm oil across different industries, making it one of the most versatile oils available. Each fraction has unique characteristics that make it suitable for specific Palm oil production is a complex process that involves a series of steps from the cultivation of the oil palm tree to the processing of the fruit into oil. Here's an overview of the primary stages: Cultivation and Harvesting 1.Planting: Oil palm trees are planted in large plantations, primarily in tropical regions. 2.Growth: Trees begin to bear fruit after 3-4 years, reaching peak production after 7-10 years. 3.Harvesting: Ripe bunches of oil palm fruit are harvested manually or mechanically. Transportation and Sterilization 4.Transportation: The harvested fruit bunches are transported to the mill for processing. 5.Sterilization: Fresh fruit bunches are sterilized by steaming at high temperatures, which stops enzymatic spoilage, detaches the fruits from the bunches, and kills oil-splitting enzymes. Threshing and Digestion 6.Threshing: The fruits are separated from the bunches in a mechanical process. Oil Extraction 8.Pressing: The digested fruit is pressed to extract a mixture of oil, water, and solids. 9.Clarification: The oil mixture is clarified by allowing solids to settle and water to be removed, yielding crude palm oil. Purification 10.Purification: The crude oil is further purified through a series of filtering and centrifugation processes to remove remaining solids and moisture. Refining (if producing refined palm oil) 11.Degumming: The oil is treated with water or acid to remove gums. 12.Neutralization: Free fatty acids are neutralized with an alkali solution. 13.Bleaching: Color pigments and impurities are absorbed by bleaching Fractionation (optional, for specific palm oil products) 15.Fractionation: The refined oil can be fractionated into solid and liquid fractions (stearin and olein, respectively) through controlled cooling and crystallization processes, followed by filtration. Packaging and Storage 16.Packaging: The final palm oil product is packaged for distribution and sale. 17.Storage: The oil should be stored in a cool, dark place to prevent spoilage and maintain quality. These steps can vary slightly depending on the specific practices of the palm oil producers and whether the end product is crude palm oil, refined palm oil, or a specific fraction of palm oil.
