Method for preparing semi-dry pleurotus eryngii by intensive pulse light treatment

Abstract

The invention provides a method for preparing semi-dry pleurotus eryngii by intensive pulse light treatment, which belongs to the technical field of deep processing of foods. The method adopts raw material pre-treatment, low-temperature salting and vacuum marinating technologies as well as a sterilization technology of primary intensive pulse light sterilization and secondary intensive pulse light sterilization together with boiling water bath to prepare the semi-dry pleurotus eryngii food. By the method, the processed pleurotus eryngi food can be eaten at any time in daily life and keeps the original nutritional ingredient, flavor and color of pleurotus eryngii; and on one hand, the excellent color and the inherent crisp and tender mouth feel of the pleurotus eryngi are kept, the pleurotus eryngi is endowed with various testes, and the variety of products is enriched, on the other hand, the shelf life of the pleurotus eryngi is effectively prolonged to be longer than 8 months. The method provided by the invention is simple in process and convenient to operate and can meet the requirements of industrial production.
