Embodiment 1

[0024] (1) 2Kg of fresh mushrooms are crushed with a mushroom grinder, mixed with 6.0L of water and crushed by ultrasonic waves. The ultrasonic crushing time of 100mL mixed solution is 30s, with an interval of 30s. The total crushing time is 5 minutes, and the ultrasonic crushing strength is 50%. Hour, obtain about 6L mushroom broken liquid.

[0025] (2) Preparation of Arthrobacter ATCC21606 disruption solution: the culture medium for Arthrobacter is K 2 HPO 4 1.5g / L, KH 2 PO40.5g / L, MgSO 4 0.5g / L, FeSO 4 1mg / L, xanthine 0.01M / L, adenine, hypoxanthine, guanine each 0.005M / L, pH7.0; cultivate Arthrobacter ATCC21606 to the concentration of OD 600 =5.0, first use high-pressure crushing directly, the crushing pressure is 20000psi; then ultrasonic crushing, the bacterial liquid volume is 100mL, the ultrasonic crushing time is 20s, the interval is 20s, the total crushing time is 5 minutes, and the ultrasonic crushing strength is 50%.

[0026] (3) Add Arthrobacter crushing solut...

Abstract

The invention discloses a preparation method for low-purine edible fungus vinegar rich in amino acid and vitamin D. The method comprises the steps that edible fungi and arthrobacter ultrasound breaking liquid are prepared; the arthrobacter (ATCC21606) breaking liquid, 5% saccharose and active dry yeast are added for alcoholic fermentation, and acetic fermentation, plate-frame pressure filtration and preparation are performed with mixed acetic acid bacteria (an acetic acid bacterium AS1.01 and Gluconacetobacter hansenii, ATCC 23769). The preparation method is characterized in that the arthrobacter breaking liquid which is high in xanthine oxidase activity is added before alcoholic fermentation is performed, acetic fermentation is performed with the Gluconacetobacter (hansenii, ATCC 23769) which can generate fiber, intermittent fermentation with standing and stirring performed alternately is adopted, vinegar liquid is sterilized through plate-frame pressure filtration, and therefore the obtained fungus vinegar is rich in amino nitrogen, safe in purine content and high in vitamin D content.

Description

technical field [0001] The invention belongs to the field of beverage processing, and in particular relates to a method for preparing edible mushroom vinegar low in purines and rich in amino acids and vitamin D. Background technique [0002] Edible mushrooms are known as "vegetable meat" and "vegetable meat". They are vegetables closest to meat and milk nutrition; some mushrooms have better protein amino acid composition than beef. Fresh mushrooms contain 5% protein, while dried mushrooms have a protein content as high as 35% to 40%, and are rich in 18 kinds of amino acids; they are rich in dietary fiber and have the effect of laxative and detoxification; they also contain a lot of trace elements, and every 100 grams of mushrooms The trace elements contained in mushrooms can meet the daily needs of the human body, and the phosphorus content is equivalent to that of fish, and the iron content is also extremely high; rich carotene can be converted into vitamin A in the human b...
