Preparation method of chestnut and kiwi fruit peptide wine

Abstract

The invention relates to a preparation method of Chinese chestnut / kiwi fruit peptide wine. The method comprises the following steps: 1) respectively peeling Chinese chestnuts and kiwi fruits, cleaning, pulverizing, and uniformly mixing to obtain a mixture; 2) sending the mixture into a microwave treatment facility, carrying out intermittent microwave treatment under the microwave frequency of 2450 MHz and the power of 500W; 3) adding water into the mixture subjected to microwave treatment according to the weight ratio of 1:(12-18), immersing in a 75-DEG C water bath for 1.5 hours, adding papain, stirring uniformly, and leaching at 40-60 DEG C for 1-4 hours, thereby obtaining an extracting solution for later use; 4) carrying out vacuum filtration by using a circulating-water multipurpose vacuum pump to obtain a peptide solution subjected to vacuum filtration; 5) adding 60-500g of unblended white wine and 30g of esterification enzyme bacterium solution into 200g of the peptide solution, carrying out natural association, transferring the wine solution into a ceramic storage tank; 6) putting the wine-solution-filled ceramic storage tank in a temperature control chamber, and oscillating the wine solution in the ceramic storage tank by using an ultrasonic oscillator; and 7) after the oscillation finishes, storing for 6-12 months, thereby obtaining the peptide wine.

Description

technical field [0001] The invention relates to the technical field of bioengineering, in particular to a method for preparing chestnut and kiwi peptide wine. Background technique [0002] Chestnut, also known as chestnuts, chestnuts, etc., belongs to perennial plants, which are rich in nutrients, containing 51-60% starch, 5.7-10.7% protein, 2-7.4% fat, 15 mg calcium, and iron per 100 grams. 1.2 mg, 1.32 mg zinc, 11.45 mg vitamin E, 0.15 mg riboflavin, 2.5 mg vitamin C, crude fiber, carotene, vitamin A, B, C and calcium, phosphorus, potassium and other minerals, which can be used by human body Up to 98% of nutrients are absorbed and utilized. Its starch content is very high, and the carbohydrates of dried chestnuts reach 77%, which is equivalent to 75% of grains; 2.4 times that of potatoes. Chestnuts are rich in vitamin B1 and B2, and the content of vitamin B2 is at least 4 times that of rice. It also contains 24 mg of vitamin C per 100 grams, which is unmatched by food. ...

Problems solved by technology

However, it is difficult to completely remove the precipitate by a single physical method, chemical method or enzymatic method, which will affect the quality of health-preserving liquor.

[0005] For the control of functional gender component indicators, there are mainly improper operation techniques, which will greatly lose the medicinal value of health-preserving liquor, and make health-preserving liquor lose its "health care" function
