AMINO ACID COMPOSITION OF GUAR GENOTYPES

Abstract

Seed powder of twenty seven guar genotypes was analysed by Waters PICD-TAG
System for quantitation of their seventeen individual amino acids. Amino acid
concentrations were found to vary considerably among the genotypes. Amino
acid profile of salt soluble and salt insoluble guar protein of nine genotypes
were also established to ascertain the superiority of two protein fractions with
respect to the presence of sulfur containing amino acids. Compared to soybean,
guar protein was also found having adequate balance of amino acids but low
in methionine and cystine.
