Problems solved by technology

Only a small part of these processing by-products are used to make low-value products such as fish meal and fish paste, and most of the rest are discarded, which not only causes waste of resources and serious pollution to the surrounding environment, but also contains valuable ingredients. fully exploited
The existing use of leftovers is mostly limited to the development of fishmeal feed, etc., without distinguishing the leftovers, increasing their production value and market value

Embodiment 1

[0031] Prepare the canned fish with the raw material of tilapia leftovers as follows:

[0032] (1) Collection of raw materials: 1000kg of fresh tilapia skeletons are rested, and the skeletons coming off the tilapia production line are collected and processed as soon as possible to ensure freshness, and collected in different specifications, according to the raw fish specifications below 500g, 500-800g, Collect fish weighing more than 800g in different sizes; cut the fish jaws from the skeleton, cut off the fins, and make a cut along the middle of the gill bone to remove internal organs and avoid bile contamination as much as possible.

[0033] (2) Cleaning of raw materials: Wash the removed fish chin with running water and place it in ice water in time; manually remove the black film inside the abdominal cavity of the chin, and wash the fish chin twice in a fish washing machine; then Place it in a fresh-keeping store to drain the water on the surface of the fish chin for 60 mi...

Embodiment 2

[0045] Prepare the canned fish with the raw material of tilapia leftovers as follows:

[0046] (1) Collection of raw materials: After thawing 2000kg of frozen tilapia jaws in ice water, arrange them according to the sub-specifications of less than 70g, 70-90g, and more than 90g;

[0047] (2) Cleaning of raw materials: Wash the removed fish chin with running water and place it in ice water in time; manually remove the black film inside the abdominal cavity of the chin, and wash the fish chin twice in a fish washing machine; then Place it in a fresh-keeping store to drain the water on the surface of the fish chin for 60 minutes, and use an electric fan to accelerate the evaporation of water.

[0048] (3) Pickling: marinate the fish chin prepared in operation (2) with the pre-prepared pickling solution at room temperature of 20°C to 25°C for 11 minutes, and then put it in the fresh-keeping store to drain the surface of the fish chin Water, the draining time is 60 minutes, and th...

Abstract

The invention discloses a method for fabricating canned fish from tilapia wastes. The method comprises the following steps: collecting raw materials; cleaning raw materials; pickling; frying; seasoning and softening; bagging and vacuum sealing; and sterilizing and packaging. By adopting the method disclosed by the invention, a traditional treatment mode of the tilapia wastes is broken through; the fish chin part is effectively separated from the tilapia wastes; the canned fish with a unique flavor is prepared by a series of treatment. Thus, the utilization rate of the overall fish is improved by 8%, the industrialized tilapia products are enriched, and a precedent is made for efficient utilization of the tilapia mossambica.

Description

technical field [0001] The invention belongs to the field of food processing, and in particular relates to a method for making canned fish from tilapia leftovers. technical background [0002] The origin of tilapia in mainland China began in the 1950s, and large-scale farming began in the 1980s. Now a good breeding, processing and production system has been formed. my country's tilapia production has ranked first in the world for many years, and tilapia has become a my country's most competitive advantage is exporting aquatic products, and the breeding areas are mainly concentrated in Guangdong, Guangxi, Hainan, Fujian and Shandong. The processing of tilapia is mainly frozen tilapia fillets, which produce a large number of by-products in the process of processing tilapia fillets. According to incomplete statistics, the content of by-products in the processing of tilapia fillets is as high as 54%. The leftovers are treated as waste, which causes a waste of resources and does ...
