The endosperm is the potential white flour within the centre of the wheat grain. When milled, the endosperm fractures along the cell walls and separates from the bran layers.
The ease of separating the endosperm from the bran layers is determined by the wheat’s characteristics. Hard wheat (used for breadmaking) will allow easy separation, whilst the endosperm of soft wheat (used for biscuit flours) does not separate as cleanly from the bran layers.
The bran layers of the wheat grain consist of four separate layers: the pericarp; testa; nucellar layers and aleurone cells. Bran is nutritionally rich in protein and is used in the production of brown and wholemeal flours.
The wheat germ is the embryo that would eventually develop into the wheat plant. It is rich in certain vitamins, protein and oil. Consequently, it is often used in health foods, such as fortified bread and wholemeal flour.
Source: It is the most common cereals product in the western world and grown in most temperate region. Large quantities are home grown and great deal particularly in the form of strong flour.
Protein present is wheat flour is gluten. Grain rich in gluten are strong flour and vice versa. Strong flour used in use din bread and soft flour for biscuit, cookies etc.
Food value: wheat is the one of the best energy food. Whole grain cereals provides vitamin B therefore protective food
Storage of wheat:
- The store room should be dry.
- It should be kept above the floor level.
- Flour should be removed from sacks and kept in wheeled bins.
- Flour bin should be a type that can be easily cleaned.
