Embodiment 1

[0051] Wash the purple sweet potatoes, remove the rotten parts, steam the purple sweet potatoes until there is no hard core, add water at a ratio of 1:0.5 and beat for later use. Add 1% wine medicine to saccharify 1d. Add 2.5 times of cold boiled water to the saccharified purple sweet potato culture medium, add 10% yeast seeds, ferment for 7 days at 28°C-30°C, stir once every 24h, and centrifuge the obtained purple sweet potato alcoholic fermentation liquid to get the supernatant. The supernatant was inoculated with 10% acetic acid seeds, and fermented at 100 rpm at 32°C for 3 days to obtain a purple sweet potato vinegar fermentation liquid. 40% purple sweet potato vinegar is blended with 30% strawberry juice, 4% honey, 6% sucrose and 20% water. After degassing, sterilizing and cooling, a fruit vinegar drink which can be directly drunk is obtained.

Embodiment 2

[0053] Wash the purple sweet potatoes, remove the rotten parts, steam the purple sweet potatoes until there is no hard core, add water at a ratio of 1:0.5 and beat for later use. Add 1.5% wine medicine to saccharify 1d. Add 2.5 times of cold boiled water to the saccharified purple sweet potato culture medium, add 7% yeast seeds, ferment for 7 days at 28°C-30°C, stir once every 24h, and centrifuge the obtained purple sweet potato alcoholic fermentation liquid to get the supernatant. The supernatant was inoculated with 10% acetic acid seeds, and fermented at 100 rpm at 32°C for 3 days to obtain a purple sweet potato vinegar fermentation liquid. 40% purple sweet potato vinegar is blended with 40% strawberry juice, 4% honey, 7% sucrose and 9% water, and after degassing, sterilizing and cooling, a fruit vinegar beverage that can be directly drunk is obtained.

Embodiment 3

[0055] Add water to the dried sweet potato according to the ratio of 1:4 and steam until there is no hard core, then add water according to the ratio of 1:0.5 to beat for later use. Add 1.5% wine medicine to saccharify 1d. Add 2.5 times of cold boiled water to the saccharified purple sweet potato culture medium, add 7% yeast seeds, ferment for 7 days at 28°C-30°C, stir once every 24h, and centrifuge the obtained purple sweet potato alcoholic fermentation liquid to get the supernatant. The supernatant was inoculated with 10% acetic acid seeds, and fermented at 100 rpm at 32°C for 3 days to obtain a purple sweet potato vinegar fermentation liquid. 40% purple sweet potato vinegar is blended with 30% strawberry juice, 4% honey, 7% sucrose and 19% water, and after degassing, sterilizing and cooling, a fruit vinegar beverage that can be directly consumed is obtained.

Abstract

The invention belongs to production technology field of health products, specifically relates to a producing method of a batata fruit vinergar beverage and the products thereof. The purple tabata or purple tabata is used as raw material and saccharomyces cerevisiae and acetic acid bacteria are used as fermentation bacteria. The obtained tabata vinergar is mixed with strawberry juice, honey, sugarand water and then is subjected to degassing, sterilizing, cooling to produce a batata fruit vinergar beverage which can be directly drunk. The avail effects are: 1) saccharified purple tabata being used as culture medium to perform alcoholic fermentation and vinergar fermentation; 2) the purple tabata vinergar being mixed with strawberry juice, honey, sugar and water to give prominence to the brewage flavor of tabata vinergar and blending with the fruit fragrance of the strawberry juice, easy to be accepted by user; 3) being natural product rich in anthocyanin and vinegar and the other effective components.

Description
