Problems solved by technology

The disadvantage is that the food will be contaminated by toxic components in the smoke (such as strong carcinogen: 3-4 benzopyrene (Bap)), some essential amino acids in the protein will be destroyed during the smoke processing, and the ash produced during the smoke And tobacco tar will also pollute food, environment, equipment and pipelines, it is difficult to realize mechanical continuous production

Abstract

The invention relates to a preparation method of a liquid smoked longsnout catfish soft can, pertaining to the technical field of aquatic product processing. In the invention, a channel catfish is taken as a raw material, and the finished liquid smoked longsnout catfish soft can is prepared through pretreatment, deboning and skinning, rinsing, draining, fishy smell removing, draining, liquid smoking, rinsing, drying, ripe preparing, vacuum packaging, sterilizing and cooling. The adoption of the channel catfish as the raw material for preparing the liquid smoked longsnout catfish soft can is very beneficial to elevating the processing level of leftovers of agricultural, livestock and aquatic products in China and can produce great economic benefit.

Description

technical field [0001] The invention discloses a preparation method of liquid-smoked catfish soft can, which belongs to the technical field of aquatic product processing. Background technique [0002] my country is rich in freshwater fish resources. In recent years, the freshwater fish breeding industry has developed rapidly, but the processing technology of aquatic products is backward. The preservation and processing of aquatic products are limited to freezing, drying, and pickling, which seriously restricts the development of freshwater fish farming in my country. [0003] Liquid smoking is a method of smoking food with liquid smoke instead of gas. Applying the liquid smoking method to aquatic food processing can not only obtain attractive smoked color and aroma, but also have antibacterial and antioxidative effects and prolong the shelf life. The flavor of smoked food is liked by quite a few consumers, and its advantages are that it provides specific flavor and good co...
