Problems solved by technology

Its disadvantage is that it adopts the deep-fried processing method and single type, which is not suitable for the current trend of healthy life and pursuit of rich taste.
[0006] Yam, hawthorn, and pineapple are all characteristic and advantageous fruit and vegetable resources. All three have extremely high nutritional value and health benefits, and the output is huge. They are mainly fresh food, and there is less deep processing, resulting in low value-added products. In addition, the water content of the three is relatively high, easy to spoilage, short storage period, easy to cause unnecessary economic losses

Abstract

The invention discloses a method for processing composite fruit and vegetable crisp chips by vacuum microwave, and belongs to the field of deep processing of agricultural products. The method comprises the following steps of: pretreatment, slicing, color protection, blanching, pulping, blending, soaking, draining, and vacuum microwave puffing and drying. The composite fruit and vegetable crisp chips processed by the method provided by the invention retain the color, fragrance, taste and nutritional ingredients of Chinese yam, large-fruit hawthorn and pineapple to the maximum extent, have attractive appearance and crisp mouthfeel, and are an ideal healthy leisure food. The method not only enriches the types of the fruit and vegetable crisp chips, solves the problems of short storage time and low product added value of the Chinese yam, the large-fruit hawthorn and the pineapple, but also promotes the development of related industries, and has great economic and social benefits.

Description

technical field [0001] The invention belongs to the field of deep processing of agricultural products, and in particular relates to a method for vacuum microwave processing compound fruit and vegetable chips. Background technique [0002] Chinese yam, also known as yam, Huai yam, Chinese yam, sweet potato, etc., is one of the traditional foods with the same origin in medicine and food in my country. Its meat is relatively tender, containing mucin, amylase and other substances, and the content is also very high.
