Abstract

The invention relates to a method for preparing freshwater fish cans through two-time liquid hot smoking. The method comprises the following steps that: (1) drying treatment is carried out to fish fillets which are fermented with lactic acid and have fishy smell removed; (2) vacuum concentration is carried out to flavor agent prepared from freshwater fish leftovers; (3) dried fish fillets are canned, and the flavor agent is injected into a can; (4) liquid smoking flavor is injected into the can to carry out primary hot smoking; (5) the can after primary hot smoking is put into a full-automatic spraying type high-temperature pressure cooker to accept secondary hot smoking; (6) the can after secondary hot smoking is cooled to normal temperature. The can prepared through method is elastic and compact in fish quality and uniform in fish fillets, and has no broken fish fillet or fat layer.

Description

technical field [0001] The invention relates to a method for processing aquatic products, in particular to a method for preparing canned freshwater fish by adopting secondary liquid heat fumigation. Background technique [0002] my country is rich in freshwater fish resources, but due to the great constraints on transportation of fresh and live aquatic products, and the sales market radius is small, it is mainly sold regionally. Therefore, it is easy to cause more production and lower prices, and the benefits are very low. However, the demand for freshwater fish series products in the northern domestic market is increasing day by day, and there is a huge room for market expansion. Especially urban residents in the north are already familiar with smoked aquatic products and are very popular. If it can be made into deep-processed products, it can directly enter hotels and supermarkets in large quantities, and become a delicacy on the consumer's table and an accompaniment to ...
