Description

Method for preparing zero-sucrose freeze-dried auricularia auricula thick soup
Technical Field
The invention particularly relates to the technical field of food processing, in particular to a method for preparing zero-sucrose freeze-dried auricularia auricula thick soup.
Background
Sugar additives in the market are mainly sucrose, however, excessive sucrose intake is easy to cause weight gain, and problems such as heart disease, diabetes, osteoporosis, gout and the like are increased in risk, and caries is easy to cause, so that skin aging is accelerated. Functional sugar substitutes have been developed to replace sucrose.
The Auricularia auricula is white in color, crystal clear, free of defects, and good in color, is a new variety of Auricularia auricula, and is rich in the reputation of ice and snow queen, and is also commonly called as "tremella. Auricularia auricula can enrich blood, reduce blood coagulation, moisten lung, and remove calculus. The Auricularia auricula-judae contains abundant polysaccharide substances in the back hair, and has high anticancer activity. Meanwhile, the traditional Chinese medicine composition also has a plurality of special curative effects of nourishing yin, strengthening yang, clearing lung, tonifying qi, reducing blood fat, reducing blood plasma cholesterol, inhibiting platelet aggregation and the like. The edible fungi have high dietary fiber content, so that the edible fungi have good help and promotion effects on gastrointestinal peristalsis, digestion and absorption of eaters; the cellulose contained in the food can decompose cellulose, is rich in colloid and phospholipid molecules, has strong adsorption capacity on insoluble fiber dust particles and the like after long-term consumption, can eliminate gastrointestinal impurities, and is an ideal health-care food in the industries of textile, mining, haircut and the like. The Auricularia is a good product of monarch in ancient times, contains a large amount of nutrients such as carbohydrate, protein, iron, calcium, phosphorus, carotene, vitamins and the like, and is rich in 17 amino acids in 20 amino acids required by human protein. Therefore, the auricularia auricula has wide application prospect.
At present, the common eating method of the auricularia auricula on the market is similar to that of the auricularia auricula, and the auricularia auricula is stir-fried or cold-mixed. It is not seen to make the black fungus soup. The invention is innovated in a large scale, and researches the auricularia auricula thick soup. The tremella thick soup has crisp and tender taste, is smooth, chewy, has rich colloid, is different from tremella, and has soft taste. The invention fills the blank of the direction of boiling the auricularia auricula thick soup and provides a new product for the market.
The cooking time of the auricularia auricula thick soup is long, and the main reasons are that the optimal gum yield is obtained, and the auricularia auricula thick soup is difficult to preserve because the auricularia auricula contains certain anaerobic bacteria, so that the economic value of the auricularia auricula is greatly influenced. According to some researches, the method has the advantages that on the premise that the crisp taste of the auricularia auricula is kept undamaged, the tissues and cells of the auricularia auricula are subjected to enzymolysis, so that colloid in the auricularia auricula can flow out in a short time, and the boiling time of the auricularia auricula is shortened. Meanwhile, the method which is popular in the market at present is adopted: freeze drying to prolong shelf life of Auricularia auricula thick soup. The invention combines freeze drying and vacuum drying, and the dried product is crisp, does not collapse, does not shrink in volume and has high restorability. The combined drying technology has been commonly used in industrial production.
Erythritol has high use value, the heat quantity of erythritol is lower, the energy of erythritol is only 0.4 kcal/g, and the erythritol is used as a sweetener, and the energy is close to 0 kcal. The human body has stronger tolerance to erythritol, is one of the most tolerant sugar alcohols, and is not easy to cause gastrointestinal discomfort such as abdominal distension, diarrhea and the like.
