Embodiment Construction

[0021] First, the waste culture medium of edible fungi is broken, and the particle size is 5 ± 1Cm. The waste culture medium of the broken edible fungi and water are put into the extraction kettle in a ratio of 1:3, and the input amount is controlled at 75% of the volume of the extraction kettle. Indirect heating and continuous stirring to prevent partial overheating and damage to the molecular structure of active ingredients. When the temperature rises to 60°C, keep warm for 5 hours and stop. Cool down to 25°C, put it into a storage tank, extract it into a centrifugal dryer for solid-liquid phase separation, and the separated solid matter enters the storage site and is used as fertilizer after natural fermentation; the liquid is poured into the concentration tank and heated indirectly. At the same time, turn on the vacuum system to keep the vacuum degree in the system at -0.08Mpa. When the temperature rises to 55°C, water vapor will be generated, and the concentration will sta...

Abstract

A process for extracting beta-glucoside from the used culture medium of mushroom includes such steps as breaking, mixing with water, indirect heating while stirring the extracting, cooling, centrifugal solid-liquid separation, indirectly heating the liquid to 40-65 deg.C, vacuum concentrating, adding antiseptic and non-ionic surfactant, and stirring.

Description

technical field [0001] The invention belongs to the technical field of chemical industry and relates to a new method for extracting β-glucoside from waste mushroom medium. Background technique [0002] In recent years, with the improvement of human economic and cultural level, people have put forward higher requirements for food safety and environmental safety. my country has also taken resolute and decisive measures to ensure environmental safety and the safety of the food chain that people directly enter. Nearly 500 kinds of highly toxic pesticides and various preparations derived from them have been strangled and production restrictions have been taken. Therefore, a batch of biopesticides represented by Bacillus thuringiensis (Bt, Bscillus.thurlingensis), abamectin, and Jinggangmycin have come out one after another, especially in recent years, including microbial pesticides, botanical pesticides, and genetically modified biochemical pesticides. Waiting for rapid developme...
