Preparation of plant source glucosamine hydrochloride

Abstract

The invention relates to a method for preparing a plant-source D-glucosamine hydrochloride. The plant-source D-glucosamine hydrochloride is mainly prepared by taking waste residues generated in the process of using the plant fermentation method to produce citric acid as raw material, and adopting the steps of acidolysis, cooling, filter pressing, decoloring, distillation and condensation, crystallization, washing, drying, and the like. Compared with prior art, the invention has the advantages of rich raw material resource, no heavy metal or antibiotic pollution, cheapness and easy obtaining. While effectively reducing the production cost, the invention finds a proper approach for treating the environment pollution so as to change waste into a treasure and also save the cost for treating the environment pollution. The invention also has simple and easy production process, good product quality, good economical and social benefit and wide market prospect.

Description

technical field [0001] The invention relates to a method for preparing plant-derived glucosamine hydrochloride, in particular to a method for preparing glucosamine hydrochloride from waste residue. Background technique [0002] Glucosamine hydrochloride, also known as glucosamine hydrochloride, is a white crystalline powder that is widely used in medicine, food and other fields. It can be used as an anti-bacterial infection and immune adjuvant, and can be used as a nutritional supplement for diabetic patients. The activator of the human body's anti-influenza virus has the effects of treating rheumatoid arthritis, enhancing human body functions and anti-aging. In addition, it can also be used in cosmetics, feed additives and as food preservatives. At present, the demand for glucosamine hydrochloride is increasing day by day. The traditional method of producing glucosamine hydrochloride generally uses chitin extracted from the shells of arthropods such as shrimps, crabs and i...

AI Technical Summary

Problems solved by technology

At present, the demand for glucosamine hydrochloride is increasing day by day. The traditional method of producing glucosamine hydrochloride generally uses chitin extracted from the shells of arthropods such as shrimps, crabs and insects as raw material, and undergoes acid hydrolysis and filtration. , Concentration, purification, re-concentration, cooling, filtration, drying and other steps, this production method has the following disadvantages: 1. Because the supply of raw materials is affected by regions and seasons, and the calcium content of shrimp and crab shells is high. Difficulties in extraction; coupled with overfishing in recent years, the number of shrimp and crabs has decreased sharply, resulting in a more scarce resource of chitin; 2. The problem of environmental pollution, especially water pollution, has become increasingly serious. Existing tests have found that there are pesticide residues in chitin , the problem of excessive heavy metal and antibiotic content, so the quality of products produced with chitin as raw material is also greatly threatened; 3. The production process is long and complicated, which also increases the production cost

[0003] In recent years, the production of citric acid has developed rapidly. Traditionally, the fermentation method is generally used for production. During the fermentation process, a large amount of waste residue is produced. It was once used as feed for trial use. However, due to the acidity of the feed, it cannot be popularized and applied, resulting in a large amount of waste residue that cannot be disposed of in time. and moldy and corrupt, therefore, the problem of finding a suitable treatment method for the waste residue needs to be solved urgently
