Research progress in processing technology of letinous edodes chips

Absrtact: In recent years, the nutritional value of Lentinus edodes has gradually attracted the attention of consumers. Lentinus edodes crisps, as a ready-to-eat leisure food similar to the nutritional composition of Lentinus edodes itself, are also widely loved by people.

In this paper, the production methods of several kinds of mushroom crisp chips used or developed in food industry are discussed. Four processing methods are briefly introduced, including vacuum frying, vacuum freeze-drying, microwave drying equipment and air-flow puffing. At the same time, the application status and the advantages and disadvantages of the processing methods in mushroom crisp industry are also discussed. In this paper, a deep comparison was made to provide theoretical guidance and technical support for the industrialization of mushroom chips.
