PROTEIN AND AMINO-ACID-COMPOSITION OF CHINESE AND NORTH-AMERICAN WILD-RICE

Chinese wild rice (Zizania latifolia Griseb.) Turcz from five lakes in Eastern China and North American wild rice (Zizania aquatica) from th e United States of America and Canada were analysed for protein conten t and amino acid composition. Protein (N x 6.25) content was respectiv ely 13.22, 13.02, 13.24 g/100 g in Chinese, American and Canadian wild rice. The amino acid compositions of the wild rice varieties from the three countries were quite similar with the exception of methionine w hich was present in lower amounts in Chinese wild rice. Threonine and lysine were the first and second limiting amino acids in all samples o f wild rice.
