Study Notes
Grain Product Technology
- Germ:
- Rich in unsaturated fats, which are heart-healthy and essential for various bodily functions
- Good source of protein, necessary for muscle growth
- Excellent source of B vitamins, including folate (B9), crucial for cell division and nervous system development
- Contains vitamin E, an antioxidant that helps protect cells from damage
- Provides minerals such as magnesium, phosphorus, and potassium, important for bone health, muscle function, and fluid balance
- Rich in antioxidants and phytochemicals that can help reduce inflammation and protect against chronic diseases
Bran
- Most fiber-dense part of the grain, providing both soluble and insoluble fiber
- Soluble fiber can help lower cholesterol and control blood sugar levels
- Insoluble fiber aids in digestion and prevents constipation
- Good source of B vitamins, essential for a healthy nervous system and energy production
- Contains minerals like iron, calcium, magnesium, and zinc, important for various bodily functions
- Rich in antioxidants and phytochemicals that can help protect against oxidative stress and inflammation
Endosperm
- Primary nutrient is carbohydrates, primarily in the form of starch, providing energy
- Moderate amount of protein, essential for building and repairing body tissues
- Good source of B vitamins, important for energy metabolism
- Contains small amounts of minerals like iron, magnesium, and zinc
- Whole grain endosperm contains some fiber, but refined grains have most of the fiber-rich bran removed
Importance of Grains/Economic Aspects
- Cereals are plants that yield edible grains, such as wheat, rice, or corn
- Grains are a major source of food (staple food crops) in many parts of the world
- China is the world's largest producer of both rice and wheat
- Grains like wheat, rice, and maize are highly efficient, yielding large quantities per acre
- Grains can be stored for long periods without significant nutritional loss if kept dry
- Easy to pack, transport, and handle, reducing costs and facilitating global distribution
- Provide a significant amount of calories in a compact form, meeting caloric needs efficiently
- Versatile in use, can be processed into various products like flour, bread, and cereals
Chronic Disease Prevention
- Regular consumption of whole grains has been linked to a reduced risk of several chronic diseases, including heart disease, type 2 diabetes, and colorectal cancer
- Fiber, antioxidants, and other bioactive compounds in whole grains may help reduce inflammation and improve overall cardiovascular health
Weight Management
- Whole grains can aid in weight management by promoting a feeling of fullness and reducing overall calorie intake
- High fiber content slows digestion and prolongs the feeling of satiety, which can help in controlling weight
Glycemic Control
- Whole grains have a low glycemic index, which means they have a slower impact on blood sugar levels compared to refined grains
Postharvest Handling of Grains
- Grain quality is largely determined during the growing season
- Once the grain has been harvested, it is difficult to improve its quality
- Quality can easily be destroyed by conditions during harvest and subsequent drying and storage
- Drying temperatures of grain destined for milling, malting, or for seed are more critical than for other uses
- If paddy is not properly dried, moisture gradient is there, and it leads to splitting during milling
Detoxification Methods
- Heat
- Irradiation
- UV and visible light
- Chlorine
- H2O2
- O3
- Bisulfite
- Ammonia
- Biological control (use of fungi and bacteria)
Other Mycotoxins
- Citrinin
- Produced by P. citrinum, P. tricinctum
- Associated with corn, barley, oats
- UV fluorescence blue-green
- Citreovorodin
- Produced by P. citreonigram
- Associated with grains
- Respiratory arrest, paralysis
