A New Method for Producing Amino Acids and Preserving Tryptophan by Using Seafood and Waste

Abstract

There are many problems in hydrochloric acid hydrolysis, and other acids are preferred. The main problem of hydrolysis is to use acid theory and calculation formula. Only the theory can be found from the textbook: the hydrolysis constant K=αNδ, which is problematic and not available. Had to establish a new theory and formula: “double Chen hydrolysis formula”.

Tryptophan can be preserved by hydrolysis with citric acid. It does not cause racemization of amino acids. You get L-amino acids, you don’t get D-amino acids. It is neutralized with hydrated lime to form insoluble calcium citrate and filtered out without any impurities. It can also remove heavy metals such as arsenic, cadmium, mercury, lead and chromium. It does not pollute the environment, retains the advantages of hydrochloric acid hydrolysis and overcomes its disadvantages. Residual calcium citrate is a good calcium supplement for livestock and poultry—is environmentally friendly.
