Making method of high-nutrition euphausia superba dry bait

Abstract

The invention discloses a making method of a high-nutrition euphausia superba dry bait. The making method comprises the following steps of (1) performing cleaning; (2) performing blanching and shaping; (3) performing water cooling; (4) performing hot air drying; (5) performing water content equilibrium; (6) performing cold air drying; and (7) performing packaging and sterilizing. According to themaking method disclosed by the invention, a production technology is optimized and adjusted, many treatment measures of performing sterilization twice, performing blanching and shaping, performing water cooling, performing drying treatment twice, performing acidification and the like are used, the technological steps are simple, the operability is high, few nutrient components are lost, the made dried euphausia superba is complete and plump, consistent in shape, uniform in color, free from brown stains, capable of being stored at room temperature for a long time, and good in palatability and food calling properties, and the moisture content can reach 30-40%, so that the high-nutrition euphausia superba dry bait is especially suitable for being used as a bait of various large-and-medium-scale aquarium fish of arowana, blood parrots, pseudorabora parva and the like.

Description

technical field [0001] The invention relates to the technical field of aquatic product processing, in particular to a method for preparing high-nutrition Antarctic krill dry bait. Background technique [0002] Antarctic krill belongs to the phylum Arthropoda and belongs to the genus Krill. Its resource reserves can reach hundreds of millions of tons. It has high nutritional value and is a new type of marine protein source resource with great development potential. However, Antarctic krill has the characteristics of enriching fluorine and has potential safety hazards to human health, which has become an important bottleneck restricting the comprehensive processing and utilization of Antarctic krill. It is a new way to use Antarctic krill to make dry products of Antarctic krill as bait for various large and medium-sized ornamental fishes such as dragon fish, blood parrot, monkfish and so on. [0003] At present, there are two main production processes of dried Antarctic krill...

AI Technical Summary

Problems solved by technology

This production method has the following defects: (1) the Antarctic krill is boiled for a long time, and the nutrients are lost greatly; (2) the fat in the Antarctic krill is easily oxidized to produce browning during the drying process by hot air drying or drying in the sun. And affect the sensory quality (color and luster appearance is not good); (3) direct cooking, the krill made is dry or curved or straight, and the shape is different; (4) the moisture content of the product is 18~20%, and the moisture content is lower , the dried Antarctic krill products are relatively brittle, dry in shape, rubbing and colliding with each other will produce more shrimp powder, resulting in the loss of dried shrimp, and the palatability and food-attracting effect are poor

[0006] Compared with heat drying, the drying temperature of low-temperature drying is lower, which can better preserve the nutritional components of Antarctic krill, but various endogenous enzymes (especially polyphenol oxidase) in Antarctic krill remain high during preservation. activity, resulting in oxidation and black spots, which affect the sensory quality of dried Antarctic krill, and the drying time of low-temperature drying is longer, the energy consumption is high, and the drying cost is relatively high, which has certain disadvantages in practical application.
