Embodiment 1

[0030] (1) Mix the natural mushroom raw materials and the compound enzyme preparation evenly, add appropriate amount of water, and activate in a water bath at 40°C for 20 minutes to obtain a mixed solution. The components of the compound enzyme preparation include 1 part of cellulase and 5 parts of pectinase , 11 parts of protease;

[0031] (2) Adjust the pH of the mixed solution to 5.0, and perform enzymatic hydrolysis at 45° C. for 2.0 hours to obtain an enzymatic hydrolysis solution;

[0032] (3) Decoct the enzymatic hydrolysis solution at 100°C, centrifuge the solution in a slightly boiling state, filter the obtained supernatant, concentrate and filter again, and use 3 times the volume of the supernatant to precipitate with ethanol;

[0033] (4) Vacuum freeze-dry the precipitate obtained in step (3) at -60°C for 11 hours to obtain mushroom polysaccharide;

[0034] (5) Using low-temperature drying technology and starch inclusion forming technology, the mushroom polysacchar...

Abstract

The invention discloses an extraction method for mushroom polysaccharide and a preparation method for a double-mushroom soup-stock essence. The preparation method for the double-mushroom soup-stock essence comprises the following steps: (1) uniformly mixing a natural mushroom raw material and a compound enzyme preparation, then adding water, and carrying out heating and activating so as to obtain a mixed solution; (2) adjusting a pH value of the mixed solution to be 5.0, carrying out enzymatic hydrolysis at 40 to 50 DEG C so as to obtain an enzymatic hydrolysate; (3) decocting the enzymatic hydrolysate, carrying out centrifugation, then subjecting an obtained supernatant to filtration, concentration and refiltration, and carrying out precipitation with ethanol; (4) subjecting obtained precipitate to vacuum freezing and drying so as to obtain the mushroom polysaccharide; and (5) with a low-temperature drying technology and a starch-coating forming technology, blending the mushroom polysaccharide and a solid-state compound seasoning product so as to obtain the double-mushroom soup-stock essence. The double-mushroom soup-stock essence provided by the invention has the advantages of flavor-improving and freshness-increasing functions of a common seasoning, nutritional values of health-care products, simple process, less equipment investment, safe and controllable production operation and food quality, stable quality, and applicability to mass production.

Description

technical field [0001] The invention relates to a method for extracting polysaccharides from mushrooms and a method for preparing heavy mushroom broth essence. Background technique [0002] With the rapid development of biochemistry, the analysis of the structure and biological activity of polysaccharides has become more and more in-depth, and it has gradually been found that polysaccharides have great utilization value for the human body. In recent years, a large number of experimental results have shown that plant polysaccharides have physiological functions such as regulating immunity, anti-oxidation, antibacterial, anti-radiation, anti-virus, lowering blood sugar, regulating blood lipids and lowering cholesterol, and have the characteristics of high efficiency and low toxicity. Plant polysaccharides can also improve the eating quality of foods, improve processing characteristics and sensory properties. [0003] As a plant polysaccharide, natural edible mushrooms are ric...
