Study Notes
Cereal Grains
- Cereal grains are seeds from grasses in the Poaceae family
- Considered the "staff of life" due to their high caloric value in human diets
- Globally, ~50% of dietary energy comes from cereals
Major Food Crops
- Wheat, Rice, Corn (Maize), and Barley are the major food crops globally
- Production percentages:
- Corn (Maize): 32%
- Rice: 29%
- Wheat: 28%
Cereal Grain Structure
- Kernels have a similar structure
- Husk/Chaff: Protective outer layer, usually inedible, protects from extreme temperatures, insects etc.
- Bran (ç³ ): Hard outer layer, excellent source of fiber and minerals (e.g. proteins, phosphorous, thiamin, B vitamins, minerals)
- Aleurone layer: Layer between bran and endosperm, contains vitamins and some fat
- Endosperm: Largest part of the kernel, starchy, excellent source of complex carbohydrates
Cereal Grain Usage
- Different parts of grains are used for different purposes
- Husk/chaff is usually not edible
- Bran is a good source of fiber and minerals
- Endosperm is the basis for flour and is an excellent source of carbohydrates
Kernel Composition
- Composition by weight:
- Endosperm: 83%
- Bran: 14.5%
- Germ: 2.5%
Cereal Grain Growth and Harvest
- Annual plants, one growing season yielding one crop, wet/dry climates influence type of grain grown
- Grains harvested from dried grasses, grains removed from stalks, separating the grains from chaff
- Types of grains (e.g. summer grains, winter grains) based on climate conditions
Cereal Storage
- Grains stored in cool and dry airtight containers to prevent pest, insect, and microbial growth
- Optimum storage conditions for longer shelf life (6-12 months)
- Relative humidity ideally below 70% to prevent microbial growth
Cereal Nutrient Content
- Carbohydrates: excellent source of complex carbohydrates
- Fiber: soluble and insoluble, good source for whole-grain products
- Fat: Very low in refined grains
- Vitamins and Minerals: present but may be lost in refining grains
- Protein: Incomplete protein, needs complementing with other sources, low in lysine
Cereal Processing
- Grain processing varies for different types of grains and products
- Brown rice: husk removed, retains bran and germ, longer cooking time, tougher texture
- White rice: bran and germ removed, less fiber, more processed
Wheat Flour
- 75% of wheat are made into flour
- Different types of flours: e.g. all-purpose, pastry flour, cake flour, semolina
- Wheat flour is the dominant baking choice due to its proteins that facilitate rising of baking goods
- Flour mixtures and their ingredients: water, flour, eggs, milk, fat, sugar, salt, flavoring, leavening agents
Pasta
- Usually made from semolina (durum wheat) and/or farina
- Semolina flour derived from durum wheat contains higher protein content
- Whole wheat pasta has higher nutrients and fiber but can disintegrate if overcooked
Breakfast Cereals
- Ready-to-eat cereals are typically made from wheat, corn, or oats
