Original Protein Hydrolysate Powder 55-60% (Soya Based)

Proteins are nutritionally a source of energy and amino acids while functionally they affect
the physicochemical and sensory properties of various foods. The role of proteins in the diet as
physiologically active components has been increasingly acknowledged. Many dietary proteins
possess specific biological properties which make these components potential ingredients of
functional or health-promoting foods. Such proteins or their precursors may occur naturally in
raw food materials exerting their physiological action direct or upon enzymatic hydrolysis in
vitro or in vivo. Dietary proteins are a source of biologically active peptides. These are inactive
within the sequence of parent protein and can be released during gastrointestinal digestion or by
enzymatic hydrolysis. Bioactive proteins are found among many biological plant materials such
as corn, rice glutelin and prolamin, wheat gluten and soy protein (Korhonen et al., 1998). The
biological activity of most of these proteins is attributed to specific peptide sequences, which are
freed by enzymatic hydrolysis. Of all oilseeds, soybeans are commercially the most important
source of protein. Soybeans have been shown to possess:
a Anti-carcinogenic properties and both animal and human studies have demonstrated that a
soy protein diet reduces high plasma cholesterol levels (Messina and Messina, 1991).
a Enzymatic digests of soy produce Angiotensin-Converting Enzyme (ACE) a inhibitory
peptides thereby exerting an antihypertensive effect.
a Isoflavones are also present in the hydrolysates and these have been shown to be beneficial
to health as they reduce the risk of heart disease, osteoporosis and cancer, when consumed
along with soy protein.
