1.0 Introduction
Protein hydrolysate could be defined as the end product of protein hydrolysis using chemical and enzymic methods. Protein hydrolysate have many uses in specialty foods such as non allergenic infant formular, diets foods and other special nutritional foods.
The drawback of many hydrolysates such as Soya or Casein hydrolysates is the bitter taste that develops when they are hydrolysated into small peptides with protease enzymes.
Protein maldigestion which is often associated with cystic fibrosis and allergy to milk protein may be overcome by replacing intact in the diet with synthetic amino acid mixture, or with enzymic protein hydrolysates. Hydrolysates may be the treatment of choice for two reasons. The amino acids and small peptides constituents of protein hydrolysates have been shown to be more readily ascribed from the small intestine than their equivelent pure amino acid mixture, more over, protein hydrolysates are considerably less expensive than synthetic amino acid mixtures. Nonetheless, protein hydrolysates suffer from a serious drawback, namely, the occurrence of a bitter taste which develops during the course of the enzymic hydrolysis.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Research questions, Limitation of the study and Definition of technical terms.
