Problems solved by technology

At present, the immobilization method used in most studies is colloidal embedding technology such as alginic acid. Although the automation and continuous acetic acid fermentation can be realized, the embedding of acetic acid bacteria by calcium alginate affects the dissolved oxygen to a certain extent. And the mass transfer process of other nutrients, prolonging the fermentation time
[0006] At present, most domestic researches on the fermentation technology of immobilized acetic acid bacteria are still in the stage of experimental research. The main purpose is to improve the fermentation efficiency. Few people pay attention to the improvement of fruit vinegar flavor and production efficiency.

Abstract

The present invention discloses a preparation method of banana composite fruit vinegar and belongs to the field of food processing. After banana pulp, longan pulp and passion fruit pulp are mixed andhydrolyzed, filtering and sugar content adjusting are conducted, and yeasts are added for anaerobic fermentation until alcohol content is 6 degrees-10 degrees to obtain banana composite fruit wine, pHvalue is adjusted to 3.5-4.5, immobilized acetic acid bacteria are added for fermentation, and aging, filtering and sterilizing are conducted to obtain the banana composite fruit vinegar. Natural organic matter is used as a carrier of acetic acid bacteria, the acetic acid bacteria can be well immobilized, production cycle is shortened, production cost is reduced, oxidation and volatilization of flavor substances of the fruit vinegar are greatly reduced, and the obtained fruit vinegar prepared by the fermentation is better and purer in taste, bright in color and luster, mellow in fruit fragrance and soft in sourness, and has typical banana, passion fruit, longan and other tropical fruit flavors. The fruit vinegar is excellent in flavor, good in mouthfeel, simple in the preparation method and low in raw material cost, and has very good application and promotion prospects.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a preparation method of banana compound fruit vinegar. Background technique [0002] Fruit vinegar is a new type of beverage that has the aroma of vinegar and fruit, and has the functions of nutrition, health care and dietotherapy, brewed by modern biotechnology, using fruit or fruit processing waste as the main raw material. [0003] At present, there are many types of high-nutrition fruits processed by fruit vinegar. Banana, passion fruit and longan are the main fruits in southern my country, with high yields. Bananas are rich in nutrients, and the pulp contains carbohydrates, potassium, phosphorus, calcium, iron and other nutrients needed by the human body. Passiflora is a perennial evergreen vine, also known as egg fruit and passion fruit. Its fruit is a typical tropical and subtropical berry. It contains more than 132 kinds of aromatic substances, and almost comb...
