Introduction :

• Cereals are the rich source of energy, protein, carbohydrate, B-complex vit. and minerals.

• Also a rich source of phytate (salts of Ca, Mg, and K)

• Abundant source of phenolic acid (antioxidant, anticarcinogenic activity)

Common cereals :• Wheat• Rice• Oat• Barley• Corn• Rye

Wheat bran

• Structure – endosperm, germ, bran layer.• Major component is cellulose.• Contain protein, omega3 , omega6 fatty acids

and antioxidants.• 15-24% dietary fibre in wheat bran.• 36% of fibre is digested by human.

Health benefits:

• Reduces the risk of coronary heart disease.• Reduce tumour mass.• Reduces the risk of developing type II

diabetes.• Have colon-cancer protective effects.• Reduce bacterial enzyme activities.

RICE

• Rice is the most important cereal product in Asia and is an overwhelming staple food in most populations.

• Excellent source of calories and provide proteins with high nutritional value.

• Hypo allergic , easily digested & versatile functional properties.

Rice Bran

• Bran layers of the rice kernel contain the highest concentration of nutrients.

• Extracted for oil and it’s a potential source of protein & other nutrients.

• Phosphorous in the form of phytates, major source of mineral constitute of rice bran.

• Abundant in B-complex vit. , tocopherols.

Health Benefits :

• Reduces serum cholestrol level.• Decreases microflora enzymes.• Possess natural antioxidants (tocopherols ,

tocotrienols ,oryzanols )• Lowers the amount of bile absorption/

reabsorption of and endogenous lipid by the lower intestinal tract and promotes the synthesis of more bile acids from available cholestrol.

Rice Bran Oil

• Oil content of clean rice bran is 20-22% which is similar to soyabean and cottonseed.

• Excellent for frying foods giving low peroxide, foam, free fatty acid and polymer formation.

Oat

• Oats (Avena sativa) are a cereal commonly eaten in the form of oatmeal or rolled oats.

• Oats are loaded with dietary fiber (containing more than any other grain) and have a range of healthy cholesterol-lowering properties.

• Active ingrident of oat is soluble fibre (1-3) (1-4)-B-D-glucan.

Health benefits :

• Oats may reduce the risk of coronary artery disease.

• Oats may help lower the risk of colorectal cancer.

• Oats may help lower blood pressure.• Stabilizes blood sugar and reduces risk of

diabetes. • Oats Help Control Blood Pressure.
