Production method of fermented olive wine and product thereof

Abstract

The invention relates to a production method of a fermented olive wine and a product thereof. The production method comprises the following steps of crushing and impregnating olive fruit and carrying out composite enzymatic hydrolysis with bentonite and gelatin for six hours to 10 hours; fermenting for 7 days to 10 days at a temperature of 15 DEG C to 20 DEG C and transferring to another tank, and post-fermenting a clear juice for 15 days to 20 days, wherein the final alcohol content is 10% vol to 12% vol; aging for one month at a temperature of 20 DEG C, carrying out freezing treatment twice, filtering and sterilizing, freezing and keeping still for 8 days at the temperature which is 0. 4 DEG C higher than the freezing point of wine, and keeping still at the temperature which is 0. 8 DEG C higher than the freezing point of wine; and finally, coarsely filtering and carrying out filtering twice by using a cardboard filter and a membrane filter, and precipitating tartrazine and black oily precipitate. The production method provided by the invention has a good low-temperature fermentation effect and high alcohol content; clarification is accelerated, the stability of wine is increased, and wine legs can be completely separated; and low-temperature freezing is carried out twice, and the tartrazine is precipitated, so that the stability of wine is further improved, and the flavor is kept. The method is applicable to the production of fermented olive wine.

Description

technical field [0001] The invention relates to a production method of fully fermented fruit wine, in particular to a production method of fermented olive wine and its products.

The pulp contains 0.8 grams of protein, 15.1 grams of carbohydrates, 0.2 grams of fat, 3 mg of vitamin C, 49 mg of calcium, 18 mg of phosphorus, and 0.2 mg of iron. The content of vitamin C is 10 times that of apples. , 5 times that of pears and peaches. It also has a high calcium content and is easily absorbed by the body. Chinese medicine believes that olives have the functions of clearing away heat and detoxification, relieving throat and reducing phlegm, promoting body fluid and quenching thirst, relieving restlessness and sobering up, dissolving thorns and removing pimples. In winter and spring, chewing 2 to 3 pieces of f...

[0003] Chinese patent application number CN 200410026767.8 "A kind of olive health wine and its preparation method" (public number CN1563334, publication date 2005-01-12) patent application discloses a kind of olive health wine and its preparation method, the olive wine mainly It is made from base wine, olive juice, Chinese herbal medicine, etc. after soaking, mixing and filtering. According to this method to make wine, first of all, the soaking method is used to produce olive wine. The types of aroma components of olive wine produced by immersion method are far lower than those prepared by fermentation method; again, this method only soaks and filters olive wine without post-treatment, so the stability is poor, and the taste of the wine is also poor and lacks flavor.
