Abstract

The invention provides a method of producing leisure foods with shrimp shells and dried small shrimps. The method includes pretreating, softening, shaping, drying by hot blast, expanding by microwave,and packing. According to the method herein, shrimp shells and dried small shrimps are pretreated first for disinfection and removal of heavy metals; the shrimp shells are softened by steam under high pressure, thereby preventing excessive hardening of the shrimp shells which affects taste; the shaping helps improve taste and palatability; drying by hot blast and stepwise expanding by microwave help produce a shrimp shell leisure food which has high expansion degree, low oil content, good taste, good eating convenience, and rich nutrition.

Description

technical field [0001] The invention relates to the technical field of food, in particular to a method for preparing snack food by using shrimp shells and shrimp skins. Background technique [0002] my country has abundant marine fishery resources, and shrimp is an important seafood. At present, my country's prawn products are mainly exported, and the export products are mainly headless prawns (shrimp). Shrimp heads and shells of prawns account for 30% to 40% of the whole shrimp mass. During the processing of prawns, a large amount of leftovers of shrimp heads and shells will be produced, some of which are processed into feed, and most of them are not fully utilized. This has not only caused waste, but also polluted the environment. It is increasingly urgent for the comprehensive utilization of a large amount of waste shrimp heads and shrimp shells produced in the processing process. The chitin content in the shrimp shell is 10% to 20%, the protein content is 20% to 40%, an...
