Study Notes
Cereal Grains
- Cereal grains are seeds of cereal grasses in the Poaceae family
- They are a major source of calories in the global food supply, comprising approximately 50% of dietary energy.
- Major food crops include wheat, rice, corn, and barley.
- World grain production: corn (32%), rice (29%), wheat (28%).
Cereal Structure
- Kernels have a similar structure.
- Husk/Chaff: outer covering, protects from extreme temperature, insects, and other elements, not usually edible.
- Bran (14.5%): hard outer covering protecting the endosperm, excellent source of fiber and minerals, proteins, phosphorus, thiamin, other B vitamins and some fat.
- Endosperm (83%): largest portion, comprised of starch, excellent source of complex carbohydrates.
- Aleurone layer: between the bran and endosperm, contains important nutrients: proteins, phosphorus, vitamin B, and fat.
- Germ (2.5%): located at the base, rich in fat, incomplete protein, vitamins and minerals. Excellent source of vitamin B and E. Very susceptible to spoilage.
Cereal Usage
- Developing countries consume more cereals than industrialized countries and transition countries.
- Usage depends on the specific cereal grain and the structure.
Harvesting and Growth
- Annual plants: one growing season produces one crop.
- Growing conditions vary by grain type, some are wet/humid (rice), others require dry/arid conditions (spring wheat and sorghum).
- Grains from dead or dry grasses.
- Harvesting: removing grains from stalks/casings.
- Threshing: releasing grain from its casing.
- Winnowing: separating grain from the chaff.
Cereal Types
- Different types/varieties of rice include: Brown rice, White rice, Enriched rice, Converted rice, Specialty Rice.
- Different types of wheat include: Winter Wheat (hard and soft), Spring wheat, Durum wheat, Common wheat.
- Different Cereal grains include those mentioned previously.
Cereal Nutrients
- Carbohydrates: excellent source of complex carbohydrates.
- Fiber: whole-grain products provide good sources of both soluble and insoluble fiber.
- Fat: very low in fat and zero cholesterol.
- Vitamins and Minerals are found in different amounts.
- Protein: incomplete, but can be complemented, with other protein sources, (e.g. legumes).
Cereal Processing (Flour)
- Wheat is the most common grain used in flour production.
- Whole-grain flours: include bran, germ, and endosperm.
- Wheat flour is a major product in common use because its protein structure facilitates baking.
- Flour mixtures often include additional ingredients like water, egg, milk, fats, sugar, salt. Types and proportions of components determine flour quality attributes.
- Major flour components include starch and gluten.
Cereal Preparation
- Pasta production uses semolina and/ or farina.
- Fresh pasta holds more moisture and has a softer consistency, compared to dried pasta.
- Best preparation temperature for pasta extrusion is 46°C.
Breakfast Cereals
- Common breakfast cereals are made from wheat, corn, and oats.
- These cereals are usually ready-to-eat.
