Abstract

The invention discloses a vacuum microwave processing method for instant Chinese yam chips, and belongs to the technical field of food processing. Chinese yam chips are given special flavor through soaking and seasoning, and then rapid processing of the low-temperature and non-fried instant Chinese yam chips is achieved by utilizing the characteristics of low puffing temperature, short heating time, fast water evaporation and less loss of nutrients of products of vacuum microwave drying technology. By means of the method, nutrient loss of Chinese yam can be effectively reduced, and the methodhas the advantages that production efficiency is high, the cost is low, nutrition is rich and taste is good. The vacuum microwave processing method includes the step that seasoned Chinese yam chips are subjected to two-stage microwave drying under the vacuum degree of -0.09 Mpa.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a vacuum microwave processing method for instant yam tablets. Background technique [0002] Chinese yam, also known as Huaishan, Chinese yam, Chinese yam, sweet potato, etc., is one of the traditional foods with the same source of medicine and food in my country. Yam is rich in nutrition, contains saponin, mucus, choline, glycoprotein, niacin, ascorbic acid, and has good disease prevention and health care functions, which can prevent cardiovascular diseases, improve body immunity, promote digestion, anti-tumor, anti-virus , anti-aging and lowering blood pressure and other effects. [0003] Vacuum microwave technology combines the instantaneity of microwave heating and the low-temperature characteristics of vacuum drying, uses vacuum devices to remove moisture, and directly uses microwaves for heating instead of transferring heat through convection or conducti...
