Abstract

The invention discloses a method for preparing amino acid nutrient solution by taking sleeve-fish processing byproduct as a raw material, comprising the following steps: preparation of a pretreatmentagent of sleeve-fish processing byproduct, adsorption of heavy metal in the sleeve-fish processing byproduct, removal of grease in the sleeve-fish processing byproduct and fermentation of the sleeve-fish processing byproduct under the action of microorganism. The method has the following steps: (1) the sleeve-fish processing byproduct is taken as the raw material, so as to reduce waste and increase the economical efficiency; (2) heavy metal elements and grease components in the sleeve-fish processing byproduct are removed; and (3) protein in the sleeve-fish processing byproduct can be completely decomposed into small-molecule amino acid and other nutritional ingredients by microorganism.

Description

technical field [0001] The invention relates to a method for preparing amino acid nutrient solution, in particular to a method for preparing amino acid nutrient solution by using squid processing by-products as raw materials. Background technique [0002] Fermentation refers to the process in which people use the life activities of microorganisms under aerobic or anaerobic conditions to prepare the microbial cells themselves, or direct metabolites or secondary metabolites. Fermentation is sometimes also written as ferment, and its definition varies depending on the occasion of use. The so-called fermentation usually refers to a certain decomposition process of organisms for organic matter. [0003] "Fermentation" originally referred to a mildly foaming or boiling state. The phenomenon of fermentation has been known for a long time, but it is nearly 200 years since its essence was understood. The word fermentation in English is derived from the Latin fervere, which origina...
