Introduction to Food Science

50% of food protein comes from cereals
Cereals are a source of energy (1400-1600 kJ per 100g whole cereal)
Cereals are important in developing countries providing two thirds of energy and protein intake

Cereals Composition

Cereals contain non-starch polysaccharides (NSP) and starch with weights making up 70-77% of the grain.
Protein constitutes 6-15% of cereals
Starch and NSP can be fermented by microorganisms in the large intestine

Various Cereal Grains and Their Uses (Sections 2. Rice, 3. Corn)

Includes varieties of rice, compositions, processing, structure, nutritional value and primary nutrients
Descriptions of wheat flour types, various categories, typical uses/applications, and compositions

Pasta

Durum wheat used for spaghetti, lasagna, linguine, and vermicelli
Macaroni, rigatoni, ziti and penne
Traditional pasta recipes are simple, using only semolina and water
Durable enough for transportation
Cohesive in cooked form due to semolina gluten protein matrix

Breakfast Cereals

Most products are made from whole grains
Popular products due to long shelf-life
