1. Anti Nutritional Factor of Protein from Plant Sources

2. Sources of protein 1. Legumes and Oil seeds = 22-40% protein d.w.
deficient in “S containing amino acids”
(for e.g. methionine and cysteine)
2. Cereals = 6-14% protein
deficient in lysine

3. Anti Nutritional Factors
anti-nutrients are that which act to
reduce nutrient intake, digestion, absorption and utilization and may produce other adverse effects.
causes depressions in growth performance and health
mechanisms include reducing protein digestibility, binding to various nutrients or damaging the intestinal wall,
thereby lowering digestive efficiency

4. Types of Anti Nutritional Factors
type A:
substances primarily interfering with the digestion of proteins or the absorption and utilization of amino acids (antiproteins) substances interfering with the absorption or metabolic utilization of minerals (antiminerals) substances that inactivate or destroy vitamins or otherwise increase the need for vitamins (antivitamins)
type B:
type C:
