Embodiment Construction

[0019] Sweet potato vinegar production process comprises the following steps:

[0020] 1. Raw material processing

[0021] Pick and remove rotten and deteriorated potato pieces, wash and remove the soil, or slice and dry in the sun, then grind, and then mix in 25% of the raw material weight of rice husk, 16% of bran, and 10% of water for steaming. 1.5 kg / cm2, keep for 1 hour, simmer for two hours, keep the steaming material, the raw material is cooked thoroughly, and the starchy raw material is truly denatured. Then take it out of the pot, let it cool, and inoculate the amylase and glucoamylase seed liquid and yeast liquid that have been cultivated first. The amount of water added is about 25-30% of the weight of the raw materials, so that the water content of the vinegar grains reaches 58-60% in winter and 60% in summer. ~62%, and then into the vat (pool for fermentation, the product temperature in the vat (pool) is preferably around 24~28°C.

[0022] 2. Starch saccharifica...

Abstract

The invention discloses a sweet potato vinegar preparing technology. The sweet potato vinegar preparing technology sequentially comprises the steps of raw material treatment, starch saccharification and alcoholic fermentation, acetic fermentation, vinegar sprinkling, sweet potato vinegar aging and sterilization, and finally finished sweet potato vinegar is obtained. By brewing vinegar with sweet potato instead of grain materials, grain can be saved. By directly using fresh sweet potato to brew vinegar, the problem that great loss is caused often when dried sweet potato is used for brewing vinegar in traditional methods is solved. Vinegar made with the technology tastes fuller and purer, sweet potato taste is richer, the vinegar is crystally amber, tastes moderately sour and sweet and leads to endless aftertastes, and the aroma can be kept no matter the vinegar is used for preparing cold dish or fried and steamed food.

Description

technical field [0001] The invention relates to sweet potato product technology in the food field, and specifically designs a sweet potato vinegar production process. Background technique [0002] Vinegar is an acid condiment created by the working people of our country in the long-term production practice, with a long history. There is an old saying "seven things to start a war, firewood, rice, oil, salt, soy sauce, vinegar and tea", and vinegar is one of them. It can increase appetite and help digestion, and is indispensable in people's life. Vinegar also has certain uses in Chinese medicine in my country.
