Abstract

The invention discloses pineapple fruit vinegar and a preparation method thereof. The preparation method comprises the following steps: okra pulp is prepared, aspergillus niger and lactobacillus plantarum are added for fermentation, pineapple pulp, Chinese yams and wolfberries are added for preparing mixed pulp, pectinase and cellulase are added for enzymolysis, aroma-producing yeast and saccharomyces cerevisiae are inoculated for wine mash fermentation, acetic acid bacteria are inoculated for acetic acid fermentation, and centrifugal filtration is conducted to obtain the pineapple fruit vinegar rich in okra polysaccharide. The preparation method disclosed by the invention is low in cost, the prepared pineapple fruit vinegar is unique in taste and rich in okra polysaccharide, and nutrientsare easily absorbed by a human body.

Description

technical field [0001] The invention relates to the technical field of fruit vinegar production, in particular to a pineapple fruit vinegar and a preparation method thereof. Background technique [0002] Pineapple, also known as pineapple, is a fruit with sufficient water and nutrition. As a high-quality raw material for the brewing process, pineapple contains a lot of fructose, glucose, vitamins, phosphorus, citric acid and protease and other substances. Bromelain can effectively decompose protein in food and enhance gastrointestinal motility; the sugar and enzyme contained in pineapple have a certain diuretic effect, which has an auxiliary effect on bronchitis, and is also beneficial to patients with nephritis and hypertension. [0003] At present, relevant researchers have developed fruit and vegetable vinegar products, but these researches on fruit vinegar are often based on traditional techniques, the raw materials and nutritional components are single, and the flavor ...
