Nutritional evaluation of a cauliflower leaf protein concentrate by rat feeding

Abstract

Abstract A leaf protein concentrate (LPC) prepared from cauliflower leaves was analysed for crude protein, calcium, phosphorus, iron, β‐carotene and some of the amino acids. Lysine and tryptophan were present in nutritionally adequate amounts, but cystine and methionine were not: Cauliflower LPC was evaluated for its nutritional qualities in respect of growth rate, protein efficiency ratio (PER), liver nitrogen, and plasma protein content by feeding rats. The growth rate of rats and PER values of leaf protein supplemented diets were better than that of the wheat flour fed group. Hence, cauliflower LPC might be used for improving nutritionally poor diets.
