The invention mainly relates to the technical field of
food processing, and discloses a preparation method of a sour and sweet dried ballonflower sauce. The preparation method comprises the following steps of enabling dried ballonflowers to be subjected to rehydration; preparing auxiliary materials; performing
fermentation; performing
concoction; and performing packing. The method is simple, and convenient to operate. The sour and sweet dried ballonflower sauce is free from any additive, safe, healthy, rich in
nutrition, sour, sweet, refreshing and crispy, further processed products of the dried ballonflowers in the market are increased, and the added value of the dried ballonflowers is increased, so that the economic returns are increased by 9.4%; the dried ballonflowers are soaked with a
vitamin C solution, so that the dried ballonflowers can be rapidly rehydrated, the color is tender and green, and the
nutrient components are increased; white funguses, eggs and wheat
bran are added, so that the fragrance can be increased, the nutrients are balanced, the adsorption is promoted, the functions of the
stomach and the intestines are strengthened, the heart and cerebral vessels are protected, and the functions of organs of organisms are promoted; and the raw materials are fermented with
lactic acid bacteria, so that the sour and sweet dried ballonflower sauce is palatable and harmonious in fragrance and moderate in sour and sweet degrees, the refreshing and crispy mouth feel of the dried ballonflower and the white funguses is maintained, massive polypeptides and
polysaccharide components are generated, the sour and sweet dried ballonflower sauce is easy to absorb, the
