The name of the crab, the three-parasitic crab, also known as occipital crab, portal crab, and three-pointed crab, is distributed throughout the seas in the north and south of China. It is usually from south to north, and is from March to May and from September to October for the production season. In recent years, as a result of over-harvesting, its resources have declined rapidly and the amount of catches has decreased significantly. However, many farmers in the coastal area have carried out artificial breeding, and the amount of marketed crabs is still sufficient.
Swallow crab meat, fat thin fat, delicious, nutritious, each protein contains 14 grams of crab meat, fat 2.6 grams. Fresh food is mainly steamed and can be salted. Crab sauce and crab eggs are rinsed and dried to become "crab seeds".
At present, the main crabs on the market are mainly cultured, live and dead crabs. Due to the large quantity, the market is in excess of supply. When the crab is under high temperature conditions, the protein is decomposed rapidly, and it is easily spoiled and deteriorated, which is unfavorable for storage and transportation. Therefore, it is very important to do a good job of deep processing and comprehensive utilization of the crab. It can make the product up-grade, increase the added value, and it is also conducive to transportation, transportation, export to foreign countries, increase the exchange rate, and increase economic and social benefits.
The processing and comprehensive utilization of the crabs mainly includes the following aspects:
First, the whole crab processing
1. The chilled crabs use crab cages to capture the crabs. After the crabs are removed from the harbor, the crabs should be immediately assembled and processed in-situ. The individual's size and degree of damage should be used to classify, pack, and re-add ice. In the hot season, it needs to be transported by a freezer truck and sold by freezers.
2. Frozen Crabs The selected chilled crabs are quickly processed into cold-preserved whole crabs in a nearby processing plant. Considering the market efficiency, currently processing female crabs is the mainstay. The processing room requires good conditions such as temperature, light, ventilation and sanitation. When processing, first pass through the high-pressure water wheel, use the seawater to wash away the mud-laden algae attached to the crab body, and then use a rubber band to clamp the crab leg tightly to prevent the leg from missing.
3. Frozen cut crabs are easy to eat and can process frozen cut crabs. The soon-to-be-cleaned crabs were cut from the center and frozen in a steel plate container.
4. Frozen cooked crabs have a high preservation requirement due to crabs, and they are good for freshness, and individual large chilled whole crabs can be boiled and frozen before being processed into frozen cooked crabs. Its characteristic is that it is convenient to eat and is not easy to degenerate, but its taste and flavor are slightly inferior.
Second, crab meat processing (mainly male crab)
1. Frozen fresh crab meat series At present, the main varieties are frozen fresh cooked crab meat, frozen fresh cooked meat (crab meat), frozen fresh cooked leg meat, frozen fresh cooked crab (face with a large chela meat).
2. Crab chilled crabs are washed, cooked, stripped of shells, and dehydrated cooked meat can be made into high-grade seafood.
3. The current export processing of canned crab meat is mostly steamed crab meat. The domestic market is canned glass crab meat, but the lower cost composite flexible packaging cans have yet to be seen and need to be developed.
4. Crab meat is mainly made of crab meat, and starch, seasoning, etc. are made into convenient fried foods - crab steak. Crab steak can be frozen and eaten easily.
Third, the comprehensive utilization of crab juice will be cooked fresh crab juice evaporated after concentration, can be used as food additives, flavor enhancer.
1. Children's puffed snack foods are mainly made of corn flour and starch. Crab sauce and condiments are added as auxiliary materials. The puffed foods are made into delicious children's puffed snack foods, such as crispy crab cakes and crab flavored pine nuts. Crab flavours can also be made according to the process of making prawn slices.
2. The artificial crab meat is mainly made of eel meat, and crab sauce, scallop meat, and seasonings are used as auxiliary materials. Crab meat, crab legs, crab sticks, and the like are manufactured through artificial crab meat processing machines.
