With the continuous improvement of people’s health awareness, fruit vinegar has received widespread attention. Fruit vinegar drinks are of high nutritional value, taste better and simple fermentation processes, therefore they are popular among consumers.Vinegar producted from grape production canp play a role in appetizing and strengthening spleen, and also have some preventive effects on hypertension and diabetes. With the healthy, natural and nutritional advantages, grape vinegar gradually become the pet of the modern beverage market, and stands out of the competition in the market. Summer black grapes cropped in jurong have a high yield and a simple planting procedure, and are rich in sugars, vitamins, amino acids, etc.. This study focused on black grapes as raw material for grape fruit vinegar.In this paper,, the application of a series of chemical and biological methods was used to investigate vinegar production process systematically by taking jurong summer black grapes as the research object. The grape vinegar producing processes, including bacteria breeding, alcoholic fermentation, acetic acid fermentation, ingredients selection and clarifying, were scientifically designed, and appropriate means tests were experimented to obtain data. The results showed that the optimum procedures for grape vinegar production are:liquid ratio 5:1, sugar amount 15%, the amount of yeast strains 7%, fermentation temperature 35℃ for and fermentation time of five days; vinegar acetic acid fermentation optimal fermentation process as follows:amount of acetic acid bacteria 12%, initial alcohol degree 5% acetic acid, fermentation temperature 30℃, ventilation volume 0.2vvm and using shake flasks fitted with steel balls. The best ingredients for grape vinegar beverage contain grape juice 20%, grape vinegar 8% and white sugar 6% or 8%; the best way to sterilize is 95℃ for lmin and to choose chitosan as the clarifying agent. Taking these into consideration, site selection, equipment selection, plans and benefits were comprehensively analyzed to discuss the production line of grape vinegar, and ultimately a vinegar production line was designed. I hope that the discussion of this article could inspirited grape vinegar production technology research and production lines designing and to promote a rapid development in jurong local vinegar industry.
