Preparation method of reshaped compound fruit and vegetable crisp chips

Abstract

The invention discloses a preparation method of reshaped compound fruit and vegetable crisp chips, comprising the following steps: pretreating multiple fruit and vegetable raw materials, mixing with auxiliary materials and pulping to obtain compound fruit and vegetable pulp; reshaping the compound fruit and vegetable pulp to form compound fruit and vegetable chips; carrying out vacuum microwave freeze predrying on the compound fruit and vegetable chips to a semidry state, and carrying out pressure differential bulking treatment on the semidry compound fruit and vegetable chips; and carrying out vacuum microwave drying on the compound fruit and vegetable chips after pressure differential bulking to obtain compound fruit and vegetable crisp chips. The method disclosed by the invention adopts a vacuum microwave freeze predrying, pressure differential bulking and vacuum microwave combined technology and a raw material compounding technology, improves the bulking degree, crispness and other qualities by adding auxiliary materials, develops non-fried reshaped compound fruit and vegetable crisp chips which are green, safe, nutrition balanced and convenient, solves the problems of unbalanced nutrition and high calories of traditional potato chips, apple flakes and other fruit and vegetable crisp chips with single raw materials, and simultaneously solves the problems of low bulking degree, relatively low crispness and the like of the traditional pressure differential bulked fruit and vegetable crisp chips.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a method for preparing reshaped composite fruit and vegetable chips. Background technique [0002] Fruits and vegetables are rich in nutrients such as vitamins, minerals, dietary fiber and plant active ingredients (polyphenols, saponins, anthocyanins, carotene, lycopene). In recent years, my country has become the world's largest producer and consumer of vegetables and fruits. According to data from the Ministry of Agriculture, the total output of fruits and vegetables in my country was nearly 1 billion tons in 2014, of which the output of vegetables exceeded 700 million tons. These fruits and vegetables are mainly used for processing and producing preserved fruits, fruit and vegetable juices, canned fruits and vegetables, dried fruits and vegetables, dehydrated fruits and vegetables and quick-frozen fruits and vegetables in addition to being used for fresh food and expo...

Problems solved by technology

[0006] Another object of the present invention is to provide a preparation method for reshaped composite fruit and vegetable chips, which adopts vacuum microwave freeze pre-drying, pressure difference puffing and vacuum microwave combined technology, and raw material compounding technology, and at the same time improves the quality of the product by adding auxiliary materials. The quality of puffing and crispness, and the development of green, safe, nutritionally balanced, convenient non-fried and reshaped composite fruit and vegetable chips; it solves the nutritional imbalance and energy of traditional potato chips, apple chips and other single-material fruit and vegetable chips. Higher problem, while solving the problems of traditional pressure difference puffed fruit and vegetable crisps, such as the decrease of puffing degree and low crispness
