Problems solved by technology

However, the common feature of these two methods is that the edible fungus cells are not broken, and only simple extraction operations such as fat extraction, alcohol extraction, alkali extraction, and water extraction are performed, and the extraction yield is relatively low. The purpose is still to extract the active components. Divided into the main, not a technology for maximum depth extraction of edible and medicinal fungus cell components
In addition, these two methods carry out alcohol extraction or fat extraction on the edible fungus dry powder in the first step, which will denature the protein, reduce the extraction rate of the subsequent process, and also destroy the flavor of the subsequent extract

Embodiment 1

[0052] 1. Select the dry fruiting bodies of shiitake mushrooms, crush them to pass through a 150-mesh sieve; weigh 1000g of shiitake mushroom dry powder, add water according to the ratio of material to liquid of 1:35 (weight ratio), and stir evenly.

[0053] 2. Adjust the pH value to 4.8, add cellulase with 0.5% weight of dry mushroom powder and pectinase with 0.5% weight of dried mushroom powder at the same time, stir and hydrolyze for 1.5 hours at 55° C.; protease, hydrolyzed at 55°C for 2 hours with stirring.

[0054] 3. The material liquid adopts the conditions of 800w, 25KHz, and 30°C, and ultrasonically breaks the wall for 30 minutes. After the wall breaking is completed, centrifuge at 4000 rpm for 15 minutes to obtain the extract and bacteria residue.

[0055] 4. Treatment of extract

[0056] (1) Add papain at 0.5% by weight of dry mushroom powder and soybean polypeptide hydrolase at 0.3% by weight to the extract at the same time, pH 7.0, stir and hydrolyze at 55° C. ...

Embodiment 2-9

[0067] Edible and medicinal fungi are selected from Hericium erinaceus, Coprinus comatus, tea tree mushroom, Pleurotus eryngii, fungus, Ganoderma lucidum, Agaricus blazei, or one of the fruiting bodies of the edible and medicinal fungi of Grifola frondosa.

[0068] The operating conditions are the same as in Example 1, and the extracts of the corresponding edible and medicinal fungus cell components are also obtained.

Embodiment 10

[0070] Using the method of Example 1, from 1000g shiitake mushroom dry powder, extract 120g (dry weight) of shiitake mushroom protein-amino acid mixture, 30g (dry weight) of shiitake mushroom nucleic acid crude product. The two extracts are mixed, and then mixed with extract: monosodium glutamate (containing 99% sodium glutamate): taste sodium nucleotide (99% purity): salt is mixed evenly according to the weight ratio of 40:38:2:20 , packaged, that is, special mushroom seasoning powder, its umami taste is 3 times that of ordinary MSG, and has a strong mushroom flavor at the same time.

Abstract

The invention discloses an edible and medical fungus cell component comprehensive extraction method and use of extract, which belong to the technical field of natural product extraction and application. The method comprises: breaking walls of the cells of the edible and medical fungi by combining an enzymic process and ultrasonic waves; extracting the extract and fungus slag by processes of water extraction, alcohol extraction and fat extraction in different sequences to obtain various nutritive components and bioactive components, such as cellulose, protein, nucleic acid, polysaccharide and fatty acid. In the invention, due to the adoption of a wall breaking-first and extraction-second scheme, the extraction rate of the cell components of the edible and medical fungi is improved considerably; the extract is extracted by water extraction, alcohol extract and fat extraction in turn and the fungus slag is extracted by fat extraction, alcohol extraction and water extraction in turn, so the flavor of the edible fungi is retained effectively; the various cell components of the edible and medical fungi serving as raw materials are extracted comprehensively and further developed; and the extracted components are natural materials, have both nutritive and health-care and pharmacological effects and can be made into various products according to the characteristics of the extracted components.

Description

technical field [0001] The invention relates to a kind of edible and medicinal fungus as raw material, which comprehensively extracts various cell components including bioactive components and nutritional components, and is used to develop various functional foods and health foods, belonging to the extraction and application of natural products technology field. Background technique [0002] In 2002, the output of edible and medicinal fungi in China exceeded 8.6 million tons. Now China has become the world's largest producer and consumer of edible and medicinal fungi, accounting for 70% of the world's total output. [0003] Compared with grains, meat and other foods, edible and medicinal fungi have distinct characteristics and obvious advantages in the three major nutrients of carbohydrates, proteins and fats. [0004] In addition to cellulose, carbohydrates in edible and medicinal fungi mainly exist in the form of polysaccharides, with a content between 25.5% and 45.4%. E...
