the two products were produced from silkworm pupae by sulphuric acid hydrolysis. they are edible and purified compound amino acid powder, with 9.05% and 13.45% of amino acid nitrogen respectively.
overloads of amino acid nitrogen could increase stress response, increase urinary nitrogen excretion and deteriorate the respiratory function.
供给氨基酸氮过多则增加应激反应,增加尿氮排出和加重呼吸负担。
with the rapeseed meals as raw material, peptide recovery ratio, soluble nitrogen and amino acid nitrogen as the indexes, the craft that rapeseed peptide was produced with bacillus.
the mechanical cell breaking could obviously increase the rate of autolysis and improve yield and the content of amino acid nitrogen in supernatant.
机械破碎可以明显缩短自溶时间,提高酵母抽提物的氨基氮含量和得率。
with the increase of the proportion of nsc, the soluble protein, ammonia concentration, peptide and amino acid nitrogen content in the culture fluid gradually decreased;
