Workshop 6 Flashcards
Cereals/ cereal grains
= edible seeds of plants, belong to grass family
Cereals are rich/low in
- Rich in carbs
- Low in fat
- Contain fair protein
- Rich in iron, phosphorus, magnesium, zinc, vitamin E, B vitamins, folate
Outer layers of cereals are rich in
in B vitamins, folate
Germ is rich in
Vitamin E
Amylose =
ex:
= tightly ordered, close bonds, require higher temperatures, more water & cooking time
Ex: Chinese rice
Amylopectin =
Ex:
= highly branched, forms looser clusters, stickier product when cooked
Ex: Japanese rice
Long-gain rice : high __ content
amylose
-> it hardens overnight in fridge
Short-grain rice : high __ content
amylopectin
- > remains soft overnight
- > sticky rice
What forms when cooking seeds in water?
Dextrin forms: enhances flavor
Grains require __ their volume in liquid
2-3 times
Gelatinization:
conversion of solid starch into a starch-water gel (improves digestibility), occurs at temperatures that depends on seed and starch (about 60-70°C)
What can help re-gelatinize
Reheating and/or adding liquid
To decrease cooking times:
Pre-gelatinization or addition of disodium phosphate
Retrogradation:
Starch molecules begins to reform in clusters, with pockets of water in between, causing the starch granules to firm up once again. = after cooking and cooling below gelatinization temp
Storage of cereals
Storage= 3-4 days in fridge once cooked
Cereal grain types :
BARLEY, CORNMEAL, MILLET, OATS, RICE, RYE, TRITICALE, WHEAT
BARLEY
- Excellent source of soluble fiber
- Used in beer production
- Flakes, grits, hulled, pearled, pot (Scotch)
- Hulled barley: includes bran, more iron, manganese, phosphorus, thiamin than pearled
- Pot barley: doesn’t have all the bran removed
