Amino acid fertiliser from which unpleasant foul smells have been removed, and production method for same

Abstract

In the present invention, the foul smell and the fishy smell that constitute disadvantages of amino acid fertilisers are given a familiar smell trusted by people, such as a savoury smell or potato smell, by means of a Maillard reaction between a reducing sugar and a sulphur-containing amino acid, thereby giving the outstanding advantage of providing a production method for a novel amino acid fertiliser able to eliminate aversion on the part of people handling the fertiliser while at the same time promoting plant physiological activity via the sulphur-containing amino acid.

Description

technical field [0001] The present invention relates to a preparation method of an amino acid fertilizer in which the malodor, which is a disadvantage of animal amino acid fertilizers, is removed and sulfur-containing amino acids effective for promoting plant growth are added. Background technique [0002] The existing amino acid fertilizers are prepared by enzymatic fermentation or hydrolysis of amino acid fermentation by-products produced during the production of seasonings, blood meal and poultry feathers produced during the slaughtering process. On the other hand, Korean Patent Publication No. 10-980595 discloses an amino acid liquid fertilizer using livestock blood, and Korean Patent Publication No. 10-284976 discloses a method for preparing a compound amino acid fertilizer using chicken feathers. [0003] The above-mentioned animal amino acid fertilizers, although there are differences depending on the processing process and decomposition method of the raw materials, a...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned animal amino acid fertilizers, although there are differences depending on the processing process and decomposition method of the raw materials, all have an unpleasant taste that makes people feel repulsed, so there are problems in use such as headaches after fertilization.

As disclosed in Korean Patent Publication No. 10-241336, when an amino acid-containing solution prepared by acid hydrolysis is used as a fertilizer, acid-resistant equipment is required to neutralize the solution, which not only requires a lot of equipment costs, but also causes Atmospheric pollution, therefore, under normal circumstances, most of them are prepared by enzymatic hydrolysis or alkaline hydrolysis, but compared with acid hydrolysis, it smells disgusting, so it can cause severe headaches or feel stress after use, Therefore, there are problems that need to be improved in time
