Abstract

The invention relates to the technical field of treatment of aquatic products and in particular relates to a method for drying pseudosciaena crocea. The method specifically comprises the following steps: (1) removing internal organs and sundries of fresh pseudosciaena crocea, and cleaning; (2) pre-treating the overall pseudosciaena crocea or diced pseudosciaena crocea; (3) performing preservationtreatment after pretreatment; (4) drying the fish meat to be 45-50% of the original weight by adopting freeze drying; (5) preserving at a temperature of 1-5 DEG C below zero, or preserving in a vacuumbag. The moisture content is moderate and is different from moisture content of the traditional dried fish; and a rehydration rate can reach 90% or higher, and the total volatile amino nitrogen is 15mg / 100g or less. According to the fish meat prepared by the method, the original taste can be reduced as much as possible after soaking, and good taste is provided for diners.

Description

technical field [0001] The invention relates to the technical field of aquatic product treatment, in particular to a method for drying large yellow croakers. Background technique [0002] Large yellow croaker is a migratory fish in warm-temperate offshore clusters, mainly inhabiting the middle and lower layers of the coast and offshore waters within 80 meters. It usually inhabits deep sea areas, and migrates to the sea to spawn from April to June. After spawning, it is scattered along the coast to seek food and feeds on fish and shrimp. Spawning fish are afraid of strong light and prefer countercurrents, preferring turbid waters with less transparency. It floats up at dawn, dusk or spring tide, and sinks during daytime or neap tide. Adult fish mainly feed on various small fish and crustaceans (shrimp, crab, mantis shrimp). The feeding intensity decreased significantly during the peak reproductive period, and increased after the end of reproduction. Juvenile fish mainly f...
