The production process characteristics and development status of fruit and vegetable crisps. The production process of fruit and vegetable crisps began in Taiwan in the early 1980s. It is necessary to use fresh fruits or vegetables as raw materials to select vacuum pump fried food or leisure snacks produced by non fried processing technology. The raw materials are relatively extensive, such as apples, pears, potatoes, sweet potatoes, carrots, banana apples, spinach baskets, Kiwifruit fruits, honeydew melons, peaches, dates Goji berries and so on. After more than 20 years of development, two major production process systems have been formed, namely the vacuum pump fried food production process and the non fried production process. The non fried production process also includes freeze-drying technology, vacuum drying, microwave drying, differential pressure expansion, microwave heating differential pressure expansion, and so on.
