Pomegranate fruit vinegar processing method

1. Fruit selection and peeling: The pomegranate fruit used for making vinegar must be fully ripe, free of pests and diseases, and must not be damaged by mildew. After peeling, the pomegranate seeds should be broken.

2. Ginger: Put sucrose and broken pomegranate seeds in a ratio of 1.2 to 1:1, a layer of sugar of pomegranate seeds, placed in porcelain, enamelware ware or dipping tank to seal.

3. Filtration of juice: The pomegranate seeds and their extracts were filtered and separated with gauze, ie pomegranate plus sugar juice was obtained, and the soluble solids were 65%-70%.

4. Dilution: The raw juice is weighed in 1 times the weight of cold water 4 times, dubbed about 16% to 18% of soluble solids in the pomegranate juice.

5. Alcohol fermentation: The raw pomegranate juice is injected into the fermentation tank. The raw juice is added to 4/5 of the fermentation tank. Access to 5% to 7% of the yeast culture stirring, control the temperature of about 25 °C for alcohol fermentation. The entire alcoholic fermentation process takes about one week to complete, with an alcohol content of around 7%.

6. Acetic acid fermentation: Add acetic acid bacteria mother liquor to acetic acid for 1/3 of the amount of pomegranate juice after fermentation. The fermentation temperature is controlled at about 30°C and the fermentation should be carried out in dark conditions. In the early stage of fermentation, it should be stirred once a day. When the total acidity no longer rises and the alcohol content is small, it is pomegranate vinegar.

7. Aging: The pomegranate vinegar is moved into a large tank for 2 to 3 months for aging. During the aging process, a series of physical and chemical changes occur in the vinegar, making the pomegranate vinegar darker in color, richer in aroma and rich in flavor. As the concentration increases, the quality is further improved.

8. Preparation: Add 2% salt, 0.08% potassium sorbate to the aged pomegranate vinegar, and adjust the acidity and other indicators according to the standard.
