Problems solved by technology

[0003] However, for the water extracts of edible fungi such as white fungus, black fungus, and white-backed fungus, the viscosity is high at low concentrations, and the equipment is easily blocked during the extraction and concentration process, which brings great inconvenience to industrialized production. Therefore, , the extraction and concentration technology for the industrial production of high-viscosity concentrated liquid of edible fungi has become a major problem in the field of concentrated liquid processing
[0004] At present, the preparation method of high-viscosity fruit juice concentrate generally adopts the method of enzymatic hydrolysis to remove pectin to reduce the viscosity, but enzymatic hydrolysis will affect the flavor and taste of the high-viscosity concentrated liquid of edible fungus and other edible fungi. Currently, there is no suitable method for high-viscosity concentrated liquid of edible fungi. preparation method

preparation example Construction

[0028] A method for preparing edible fungus high-viscosity concentrate, specifically: after washing the edible fungus with water, ultrasonic countercurrent extraction, vibrating screen and disc centrifuge filtration, UHT sterilization, four-effect seven-stage heat-accelerated instantaneous evaporation and concentration container concentration, aseptic filling; its specific preparation steps are as follows:

[0029] Step S1: Soak the edible fungus for 5-20 minutes and then wash to remove surface sediment;

[0030] Step S2: Cut the cleaned edible fungi into cubes of 0.5cm×0.5cm; find a method for preparing a high-viscosity concentrated liquid of edible fungi described in 1, characterized in that in step S2, the washed edible Bacteria are cut into cubes of 0.5×0.5cm for the convenience of subsequent filtration. If they are powdered for extraction, the subsequent powder will become a paste, and the filtration resistance will be greatly increased. It is necessary to increase the ro...

Abstract

The invention relates to a concentrated solution, in particular to a preparation method of an edible mushroom high-viscosity concentrated solution, which comprises the following steps of: cleaning edible mushrooms by using water, and treating by using the methods of ultrasonic countercurrent extraction, filtration by using a vibrating screen and a disc centrifuge, UHT sterilization, concentration by using a four-effect seven-stage heat acceleration instantaneous evaporation concentrator, sterile filling and the like. The difficulty in extracting and concentrating the edible mushroom concentrated solution can be obviously reduced. According to the method, the filtering difficulty caused by high viscosity in the traditional extraction method is avoided; according to the preparation method of the edible mushroom high-viscosity concentrated solution, the concentration efficiency can be improved by utilizing a four-effect seven-stage thermal acceleration instantaneous evaporation concentrator, and the product quality is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of edible fungus deep processing, in particular to a method for preparing edible fungus high-viscosity concentrated liquid. Background technique [0002] Edible fungi are rich in protein, carbohydrates, multivitamins, trace elements, amino acids and other nutrients. The protein and amino acid content is several to dozens of times that of ordinary vegetables and fruits. Edible fungus is very popular because of its unique flavor, delicious taste and rich nutrition. The edible fungus concentrate can be used to prepare edible fungi juice drinks and act as a thickener, and can also be used to extract polysaccharides for use in medicine, food, cosmetics, health care products and other products. It has a wide range of uses and is suitable for the deep processing industry of edible fungi. [0003] However, for the water extracts of edible fungi such as white fungus, black fungus, and white-backed fungus, the viscos...
