Soya flour is made by grinding roasted soybeans into a powder. Soya bean flour is considered a health food, and is used in many food products. With increasing awareness about health, there is a distinct shift towards soya products including its flour. Its use as a supplement to wheat flour is increasing substantially in many households. Rich in high-quality protein and other nutrients, soy flour also adds a pleasant texture and flavour to foods.
Two kinds of soy flour are available:
• Natural or full-fat soy flour, which contains the natural oils that are found in the soybean.
• Defatted soy flour, which has the oils removed during processing.
Maize has become a staple food in many parts of the world, with the total production of maize surpassing that of wheat or rice. However, little of this maize is consumed directly by humans: most is used for corn ethanol, animal feed and other maize products, such as corn starch and corn syrup. The six major types of maize are dent corn, flint corn, pod corn, popcorn, flour corn, and sweet corn.
Wheat flour is a powder made from the grinding of wheat used for human consumption. Wheat varieties are called “soft” or “weak” if gluten content is low, and are called “hard” or “strong” if they have high gluten content. Hard flour, or bread flour, is high in gluten, with 12% to 14% gluten content, and its dough has elastic toughness that holds its shape well once baked. Soft flour is comparatively low in gluten and thus results in a loaf with a finer, crumbly texture. Soft flour is usually divided into cake flour, which is the lowest in gluten, and pastry flour, which has slightly more gluten than cake flour.
