Abstract
A preparation method of an essence containing probiotic fermented carrot extract comprises the steps of preparing a carrot essence base material, preparing carrot enzymolysis fermentation liquor, and preparing carrot essence by blending the fermentation liquor and the carrot essence base material. The invention takes carrot as raw material, and the essence containing probiotic fermented carrot extract is prepared by hydrolyzing and coupling probiotic fermentation treatment by cellulase and pectinase, separating the obtained supernatant and blending the separated supernatant with carrot essence base material. The carrot essence prepared by the method can effectively overcome the defects of monotonous fragrance, poor natural feeling, short fragrance-holding time and the like of the traditional carrot essence, has the unique natural flavor of carrot, pure and strong fragrance, vivid fragrance, mellow mouthfeel, obviously improved stability and fragrance quality, good probiotic effect and can be widely used for preparing various beverages, dairy products, baked foods, candies and other foods.
Description
Technical Field
The invention belongs to the technical field of food. Relates to the preparation of essence.
Background
In China, carotene has the reputation of 'xiao ginseng', is rich in nutrition, contains a large amount of beta-carotene, can be converted into vitamin A in vivo, can improve the immunity of the organism, and has the effects of preventing myopia, resisting viruses, tumors and the like. However, carrots, especially most of vitamins and trace elements in carrots, are easily damaged during high-temperature production and processing, so that the original flavor of the carrots disappears, and the quality of products and the acceptance of consumers are affected.
In recent years, carrot flavor has been developed and used in various foods. At present, the production raw materials of the traditional carrot essence are mainly monomer ester fragrant raw materials which are artificially synthesized, the carrot essence produced by using the raw materials has certain carrot flavor, but the fragrance is stimulated and not soft, and compared with the real carrot fragrance, the natural feeling is not strong enough, the fragrance stability is not good, and the fragrance and fragrance effect is not good, so the application field of the carrot essence is limited to a certain extent.
The invention aims to make up the defects of the traditional carrot essence formula, the carrot essence prepared by probiotic fermentation is added into a carrot essence base material, the taste and the fragrance of an application product of the carrot essence prepared by the method can be obviously improved, the unpleasant taste of a synthetic raw material in the carrot essence is covered, the fragrance of the carrot essence is closer to the real fragrance of carrots, and the carrot essence prepared by using a monomer synthetic spice in the prior art cannot match the fragrance of the carrot essence prepared by using a monomer synthetic spice.
