Abstract

The invention provides purple sweet potato thick wine and a preparation method thereof, and relates to the field of wine preparation. The invention is intended to solve the problem how to prepare thewine through the deep processing of sweet purple potatoes. The preparation method comprises the following steps of: steaming the sweet purple potatoes, adding water, pulping, carrying out color protection, ultrasonic treatment, enzymatic hydrolysis, liquefaction and saccharification in sequence to obtain feed liquid, then fermenting the feed liquid by using lactic acid bacteria and saccharomyces cerevisiae in sequence, and finally compounding the feed liquid, white sugar, citric acid and edible essence to prepare the purple sweet potato thick wine. The preparation method is suitable for the development and production of sweet purple potato deep processing products.

Description

technical field [0001] The invention relates to the field of wine making, in particular to a purple sweet potato thick wine and a preparation method thereof. Background technique [0002] Sweet potato is a root tuber plant of Convolvulaceae, known as the seventh largest carbohydrate source crop in the world. It has the characteristics of wide growth range, barren tolerance, drought tolerance, high and stable yield and so on. Sweet potato used to be one of the most stable carbohydrate source crops in Asia and Africa, and played a huge role in solving the population growth and food and clothing problems in developing countries. In recent years, my country's sweet potato planting area has stabilized at 4.5 million hectares, accounting for 45%-50% of the world's total sweet potato area. The annual total output is about 100 million tons, accounting for 75% of the world's total. It is the world's largest sweet potato production and consumer country. [0003] Purple sweet potato i...
