Result Amino acid compound counld reduce the MDA contents in the serum of middl.

The paper make the quality analysis of the composite amino acid injection in Pico · TagTMystem of Waters company, and vatuale overall the method.

The animal experimental study on improving growth and development by the amino acid complex preparation;

Amino acids in the product are complete;the chelative effect of trace elements and complex amino acids in the production are good.

Via hydrochloric acid hydrolyzing,complex amino acid was gained with pine pollen as material.

This paper reported the producessing technology on preparing complex amino acids from plant spent protein resources-cottonseed cake and rapeseed cake hydrolyzed by HCl, and the optimum parameters were: the HCl concentration 4mol/L, the ratio of cake to water is1:4(g/g), reacting 9h under 126℃ with added pressure.

Study on technology in preparation of compound amino acids from feather by microwave hydrolyzation;

The effect of compound amino acid on the growth,chlorophyll-a content and oxygen releasing of Chlorella pyrenoides;

Study on technology of preparing compound amino acids of defatted silkworm chrysalis by acid hydrolysis

Manufacturing technology of chelation of amino acids with microelements;

Researches were carried out to determine effects of different chemical reagents on hydrolyzation of chicken feathers under acid or alkali conditions in order to select a suitable catalyst to enhance transformation of organic nitrogen into amino acids.

It is Scddied in the poper that amino acid is prepared by means of the combination ofhydrolysis of plant proteinasc and organic acid and the experiment indicates that hydrolysis of animalblood catalyzed by the combination of protetinase and acid is superior to that catalyzed only byproteinase or acid.
