Embodiment 1

[0079] Embodiment 1: a kind of production technology of shiitake mushroom extract, comprises the following steps:

[0080] 1. Take shiitake mushrooms and crush them and add water with a weight ratio of 1:3.

[0081] 2. Add 1% salt (NaCl) of the quality of the shiitake mushrooms and adjust the pH to 4, autolyze for 8 hours at a temperature of 40° C., and adjust the pH by using acetic acid or hydrochloric acid and sodium hydroxide solution.

[0082] 3. Add 0.2% protease of the mass of shiitake mushrooms, enzymatically hydrolyze for 1 hour under the condition of PH=4.5 and temperature of 45°C, and use papain or microbial protease as the protease;

[0083] 4. After deactivating the enzyme, separate the filtrate, which can be separated by centrifugation or filtration to remove the residue of the shiitake mushrooms to obtain a clear liquid; generally heat at 95°C for 15 minutes to deactivate the enzyme;

[0084] 5. Add 5'-phosphodiesterase enzyme solution with a volume of 1.25% of ...

Embodiment 2

[0087] Embodiment 2: a kind of production technology of shiitake mushroom extract, comprises the following steps:

[0088] 1. Take shiitake mushrooms and crush them and add water with a weight ratio of 1:14,

[0089] 2. Add 5% salt (NaCl) of the quality of shiitake mushrooms and adjust the pH to 8, and autodissolve for 20 hours at a temperature of 65°C.

[0090] 3. Add 1.0% protease of the mass of shiitake mushrooms, and enzymatically hydrolyze for 6 hours under the conditions of pH = 7.5 and temperature of 75°C. The protease is papain or microbial protease;

[0091] 4. After deactivating the enzyme, separate the filtrate, which can be separated by centrifugation or filtration to remove the residue of the shiitake mushrooms to obtain a clear liquid; generally heat at 95°C for 15 minutes to deactivate the enzyme;

[0092] 5. Add 5'-phosphodiesterase enzyme solution with a volume of 4.25% of the filtrate to the filtrate, and perform enzymatic hydrolysis for 5 hours under the co...

Embodiment 3

[0095] Embodiment 3: a kind of production technology of shiitake mushroom extract, comprises the following steps:

[0096] 1. Take shiitake mushrooms and crush them and add water with a weight ratio of 1:5. Fresh shiitake mushrooms (water content 89.6%) are washed, drenched, crushed, added with 2 times the weight of fresh shiitake mushrooms, made into a homogenate with a beater, and then added with 3 times the weight of fresh shiitake mushrooms. 2. Add 2% salt (NaCl) of the quality of shiitake mushrooms and adjust the pH to 5, and autolyze for 14 hours at a temperature of 45°C.

[0097] 3. Add 0.4% protease of the mass of shiitake mushrooms, enzymatically hydrolyze for 2 hours under the conditions of pH=5.5 and temperature of 55°C, and use papain or microbial protease as the protease;

[0098] 4. After deactivating the enzyme, separate the filtrate, which can be separated by centrifugation or filtration to remove the residue of the shiitake mushrooms to obtain a clear liquid;...

Abstract

The invention relates to a method for producing mushroom, which comprises that breaking mushroom and adding water, adding common salt to dissolve for 2-20h, adding some prolease to process enzymolysis, disinfecting enzyme and separating the filter solution; adding 5'-phosphodiesterase into filter solution to process the enzymolysis, disinfecting the enzyme and separating to obtain the filter solution; concentrating the filter solution into paste or atomizing and drying into powder. The invention processes two times of enzymolysis, while the product is abundant in amino acid, polypeptide, polysaccharide, or the like. And the invention has high solubility and stability in neutral or weak-alkali water solution, and some solubility in weak-acid water solution.

Description

technical field [0001] The invention relates to a deep processing technology of shiitake mushrooms, in particular to a production technology of shiitake mushroom extract. Background technique [0002] Lentinus edodes is a famous edible fungus in my country, known as "mountain delicacy" among the people. It is also one of the famous edible and medicinal fungi in the world. It contains protein, 17 kinds of amino acids, unsaturated fatty acids and multivitamins, especially rich in provitamin D (ergosterol). In addition, it contains lentinan (LNT for short), lentysin, eriadenine and its derivatives. Shiitake mushrooms are not only delicious and nutritious, but also can regulate metabolism and enhance physical fitness. They are known as "hygienic food" and "modern food". At present, they are developing into the third type of food besides plant and animal foods - mushrooms. physical food. In order to make full use of the flavor substances, nutrients and functional substances in...
