Problems solved by technology

Among them, the Soxhlet extraction method is simple to operate, but the extraction rate is slow and the solvent consumption is large.
Microwave extraction and ultrasonic extraction are less harmful to the environment, but the temperature is easy to rise and difficult to control during the extraction process, which is not conducive to the stability of hesperidin, and is not suitable for large-scale industrial production
The traditional large-scale production of alkali extraction and acid precipitation method is cheap and simple, but the large consumption of lime water is easy to pollute the environment, and the extraction time is long. The disadvantages of this method have become more and more obvious.

Abstract

The invention discloses a method for preparing natural hesperidin through biological fermentation and extraction. Firstly, a fermentation culture solution is prepared, and is mixed with fresh tangerine peel or orange peel; then steam explosion treatment is performed, the material is inoculated with microorganisms and culture is performed, then parameters such as temperature and ventilatory capacity are adjusted for enzymolysis, crystallizing is performed after the enzymolysis is completed, and filtering is performed to obtain the natural hesperidin. The yield of the natural hesperidin can reach 42%. According to the method, the fresh tangerine peel or orange peel is directly used as the raw material, and operations of drying, crushing and the like are not needed, so that degradation of the hesperidin under the high-temperature condition in an extraction stage is avoided, the pollution of alkali liquor such as lime water to the environment is also avoided, the equipment requirement in the whole process is simple, the process flow is short, and the extraction yield of the hesperidin is high.

Description

technical field [0001] The invention relates to plant extraction technology, in particular to a technical field, in particular to a method for preparing natural hesperidin through biological fermentation extraction. Background technique [0002] Hesperidin is a natural functional component with various biological activities, which is widely used in the fields of medicine, food and chemical industry. Hesperidin has many functions such as maintaining normal osmotic pressure of blood vessels, enhancing capillary toughness, lowering cholesterol, regulating immunity, and anti-cancer and anti-tumor. Hesperidin widely exists in orange peel and orange peel, and the efficient and environmentally friendly extraction of hesperidin from orange peel and orange peel is of great significance for improving the added value of the citrus industry. At the same time, hesperidin is the raw material for the synthesis of new sweetener neohesperidin dihydrochalcone. [0003] At present, the main ...
