Lecture 1: Food Selection Reviewer People choose food and beverages based on several factors; -how food looks -taste -health -cultural -religious values -psychological and social needs -Budgetary cincern 2.1 Sensory Perception - Sight: The first impression of food is visual, influencing perceptions of quality and desirability. Factors include: - Shape - Color - Consistency - Serving size - Presence of defects - Smell: Smell is almost as important as appearance in evaluating food. - Most people can differentiate between 2,000 to 4,000 odors. - Trained individuals can distinguish as many as 10,000. Classifications of Odors: - Six Classifications: Spicy, Flowery, Fruity, Resinous, Burnt, Foul - Four Classifications: Fragrant (Sweet), Acid (Sour), Burnt, Caprylic (Goaty) - Adaptation: Perception of a continuously present smell gradually decreases over time. - Volatile Molecules: Molecules capable of evaporating like a gas into the air. These molecules travel through the air and reach the olfactory epithelium, located inside the upper part of the nasal cavity. - Taste: Taste is perceived through the interaction of food with taste buds. Five Taste Stimuli: —Sweet, Sour, Bitter, Salty, Savory (Umami) Chemical Basis of Taste: - Sweetness: From the chemical configuration of sugar molecules. - Sourness: From acids found in food, related to the concentration of hydrogen ions. - Bitterness: Imparted by compounds like caffeine, theobromine, and phenolic compounds. - Saltiness: From salt ions, such as those found in sodium chloride. - Savory (Umami): Imparted by glutamate, an amino acid found in beef broth and MSG. - Factors Affecting Taste: Temperature, color, time of day, age, gender, and hunger. - Touch: Touch involves both tactile perception and mouthfeel. - Texture: A combination of perceptions involving sight, touch, and mouthfeel. - Consistency: Describes a food's firmness or thickness, including brittleness, chewiness, viscosity, thickness, thinness, and elasticity. - Astringency: Causes puckering of the mouth due to the drawing out of proteins in saliva and mucous membranes. - Chemethesis: The ability to feel a food's chemical properties (capsaicin), such as the coolness of mint or the heat of chili peppers. 2.2 External Influences - Nutritional Criteria: Food choices are often influenced by nutritional considerations, such as: - Food Group Plan: A diet-planning tool that groups foods based on nutrient and calorie content. - Cultural Criteria: Culture plays a significant role in food choices. - It dictates what is considered acceptable to eat. Factors influencing cultural food choices include: - Place of birth - Ethnic influences - Geography and climate - Cultural influences on manners Religious Criteria: Religious beliefs often dictate dietary restrictions. - Hinduism: Avoidance of beef and pork. - Buddhism: Mostly vegetarian, emphasizing compassion and karma. - Islam: Halal dietary laws, prohibiting the consumption of pork and alcohol. Psychological and Social Criteria: Psychological and social factors strongly influence food habits. - Social: Food choices can be influenced by social gatherings, dining etiquette, and peer pressure. - Psychological: Emotional states, stress levels, and personal preferences can impact food choices. - Budgetary Criteria: Cost is a major factor in food choices. - Convenience Foods: Time constraints can lead to greater reliance on convenience foods, even if they are more expensive or less nutritious. Key Takeaways - Food choices are influenced by a complex interplay of sensory experiences, cultural norms, religious beliefs, psychological factors, social pressures, and budgetary constraints. - Understanding these factors is crucial for individuals making informed food choices and for professionals working in the food industry.

Dull knives are more dangerous, as they require more pressure and are more likely to slip. - Chopping board: Use a clean chopping board with a damp towel underneath to prevent slipping. A clean workspace is important for food safety. Knife Safety: - Cut away from your body: Always cut away from your body to prevent accidental cuts. This is a basic rule of knife safety that should never be ignored. - Do not attempt to catch a falling knife: If a knife falls, let it fall. Do not attempt to catch it. Catching a falling knife is a recipe for disaster. - Do not run with a knife: Running with a knife is extremely dangerous and should be avoided. This is common sense, but it's worth repeating. - Hand over the knife handle-first: When handing a knife to someone, always hand it over handle-first. This prevents the recipient from accidentally grabbing the blade. - Keep knives sheathed when storing or carrying: Always sheath knives when not in use to prevent accidents. This is especially important if you're carrying a knife around the kitchen. - Keep knives sharp: Sharp knives are safer than dull knives because they require less pressure to cut, reducing the risk of slipping. A dull knife is more likely to slip and cause an injury. - Do not use a knife for prying open objects: Knives are designed for cutting, not prying. Use a tool designed for the task. Using a knife for prying can damage the blade and make it more likely to break. - Do not use a knife on live electrical items: Using a knife on live electrical items can be fatal. This should go without saying, but it's worth repeating. - Seek first aid when cut by a knife: If you are cut by a knife, seek first aid immediately. Even a small cut can become infected if not treated properly. Basic Cuts: - Julienne: Thin, matchstick-like strips. Used for vegetables in stir-fries, salads, and other dishes. - Large Dice: Cubes of approximately 1/2 inch. Used for vegetables in stews, soups, and other dishes where a larger bite is desired. - Small Dice: Cubes of approximately 1/4 inch. Used for vegetables in salads, stir-fries, and other dishes where a smaller bite is desired. - Batonnet: Long, thin sticks of approximately 1/4 inch by 1/4 inch. Used for vegetables in stir-fries, salads, and other dishes where a uniform shape is desired. - Medium Dice: Cubes of approximately 1/3 inch. Used for vegetables in stews, soups, and other dishes where a medium-sized bite is desired. - Fine Julienne: Very thin, matchstick-like strips. Used for vegetables in salads, stir-fries, and other dishes where a delicate texture is desired. - Brunoise: Very small cubes, approximately 1/8 inch. Used for vegetables in sauces, soups, and other dishes where a fine texture is desired. Measurements of Dry and Liquid Ingredients: - Dry Ingredients: - 1 cup: 8 ounces. This is a standard measurement for dry ingredients like flour, sugar, and rice. - 1/2 cup: 4 ounces. Half of a cup. - 1/4 cup: 2 ounces. A quarter of a cup. - 1 tablespoon: 1/2 ounce.

Lesson 4: BFP Cooking Methods Summary Objectives: - Identify the methods of heat transfer: Conduction, convection, and radiation. - Identify different moist heat cooking methods: Blanching, poaching, boiling, simmering, steaming, and braising. - Demonstrate a moist heat cooking method. - Identify different dry heat cooking methods: Baking, roasting, grilling, barbequing, broiling, pan-broiling, pan-frying, sautéing, and deep frying. - Demonstrate a dry heat cooking method. Key Takeaways: Heat Transfer: - Conduction: Direct transfer of heat through contact. - Convection: Heat transfer through the movement of fluids (liquids or gases). - Radiation: Heat transfer through electromagnetic waves. Moist Heat Methods: - Blanching: Briefly immersing food in boiling water to remove membranes or preserve color. - Poaching: Cooking food in a liquid at a low temperature (140°F - 180°F). - Boiling: Cooking food in boiling water (212°F). - Simmering: Cooking food in liquid at a temperature between 85°C and 96°C. - Steaming: Cooking food directly in steam. - Braising: Searing food and then cooking it slowly in a small amount of liquid. Dry Heat Methods: - Baking: Cooking food in an oven using dry heat (121°C - 246°C). - Roasting: Cooking food uncovered in an oven to produce a browned exterior and moist interior. - Grilling: Cooking food directly over heat, often using charcoal or an electric grill. - Barbequing: Grilling food at low temperature and basting with a sauce. - Broiling: Cooking food under direct heat from above. - Pan-broiling: Cooking food in a pan or skillet without added fat. - Pan-frying: Cooking food in a pan with a moderate amount of fat. - Sautéing: Cooking food quickly in a small amount of fat over high heat. - Deep frying: Submerging food in hot fat, typically used for breaded or battered foods. Additional Notes: - Food Technologist Role: Food technologists can work as quality assurance officers in commissaries or large kitchens, ensuring food quality and proper cooking techniques. - Importance of Cooking Methods: Understanding different cooking methods is crucial for assessing food quality, ensuring proper doneness, and preventing overcooking or undercooking. - Eggs Cookery Techniques Summary Key Techniques: Boiled Eggs: - Emphasizes "simmering" over "boiling" for even cooking and texture. Simmering refers to gently heating a liquid just below the boiling point, ensuring a more consistent and gentle cooking process for eggs. - Covers different levels of doneness: coddled (very soft yolk), soft- (slightly set yolk), medium- (set yolk), and hard-cooked (fully set yolk). - Addresses the green ring formation around the yolk, which occurs due to a chemical reaction between sulfur in the yolk and iron in the egg white when overcooked or cooked at too high a temperature. Tips for prevention include avoiding overcooking and peeling eggs promptly after cooking. Baked Eggs: - Includes variations like shirred eggs (baked in a shallow dish), eggs sur la plate (baked directly on a plate), and eggs en cocotte (baked in a ramekin). - Highlights the importance of using fresh eggs, which have a more centered yolk and less likely to break during cooking. - Emphasizes the role of baking dish size and material in affecting texture and baking time. For example, a smaller ramekin will result in a quicker cooking time and a more concentrated flavor. Poached Eggs: - Focuses on creating attractive, regular-shaped poached eggs. The key is to gently slide the egg into simmering water, ensuring the white sets evenly without spreading too much. - The use of vinegar to prevent egg whites from spreading. The acid in vinegar helps to coagulate the egg white more quickly, resulting in a neater shape. - Provides instructions for reheating poached eggs for service. This is particularly useful for buffets or large gatherings where eggs may need to be prepared in advance. Fried Eggs: - Emphasizes the importance of fresh eggs, proper heat level, and cooking fat for achieving a high, centered yolk. Fresh eggs have a thicker white, which helps to hold the yolk in place during cooking. - Covers different levels of doneness: sunny-side up (yolk runny), over easy (yolk runny but turned), over medium (yolk slightly thickened), and over hard (yolk fully set). Scrambled Eggs: - Focuses on achieving a creamy texture and small curds. This is achieved by gently stirring the eggs over moderate heat, ensuring they cook evenly without overcooking. - Provides tips for adding moisture and flavoring ingredients. Adding a small amount of milk or cream helps to create a lighter and more tender texture. - Highlights the importance of serving scrambled eggs hot and fresh. This ensures the best flavor and texture. Omelets: - Covers three basic styles: rolled (French-style), flat (farmer-style, frittata, or tortilla), and souffléed (puffy). - Provides detailed instructions for each style, including filling techniques and doneness indicators. For example, a rolled omelet is cooked until set, then rolled into an oval shape, while a flat omelet is cooked on the stovetop and then finished in the oven. Quiche: - Explains the basic process of making a quiche, including custard preparation (a mixture of eggs, milk, and cream), filling techniques (adding ingredients like cheese, bacon, or vegetables), and baking instructions. - Emphasizes the importance of letting the quiche rest before cutting for optimal shape retention. This allows the custard to set properly and prevents the slices from falling apart. Soufflés: - Highlights the importance of careful technique and timing for achieving a successful soufflé. Soufflés rely on the air whipped into the egg whites to create their signature rise and lightness. - Provides detailed instructions for separating eggs, whipping whites to soft peaks (not over-whipped), and folding them gently into the base. - Emphasizes the importance of serving soufflés immediately after baking. Their airy texture will deflate quickly as they cool. Note: - Ingredient Selection: Freshness and quality of eggs are crucial for achieving optimal results. Fresh eggs have a thicker white and a more centered yolk, resulting in better texture and appearance. - Heat Control: Proper heat management is essential for even cooking and preventing overcooking or undercooking. Overcooked eggs can become rubbery and dry, while undercooked eggs may be runny and unsafe to eat. - Technique: Mastering specific techniques for each preparation is vital for achieving desired textures and appearances. For example, the gentle stirring of scrambled eggs or the careful folding of soufflés are essential for achieving the desired results. - Doneness: Understanding different levels of doneness for various egg preparations is important for satisfying customer preferences. Some people prefer their eggs runny, while others prefer them fully cooked. - Service: Serving eggs hot and fresh is crucial for maintaining quality and maximizing enjoyment. Eggs lose their texture and flavor as they cool. Lesson 5-Five Mother Sauces Reviewer.
