Description

Whole krill type bait capable of being directly used and preparation method thereof
Technical Field
The invention relates to the technical field of bait, in particular to direct-use bait prepared from whole krill and a preparation method thereof.
Background
The strong and weak food calling of the bait to fish is one of the key factors influencing the fishing effect. The current common baits mainly comprise two types, one is living baits such as earthworms, flour weevils, shrimps and the like, and the other is dry powder or granular baits which are formed by combining various powder materials as a formula. The live baits have strong food calling performance to fishes, but the live baits are not easy to collect and have short preservation period, are difficult to store for a long time, need to be bought for use at present and are difficult to meet the requirements of fishermen. The dry powder or granular bait is convenient to store and can be used at any time, so that the bait in the market is mainly prepared from the product. However, the product needs to be mixed with water to be prepared into blocks before use, certain experience is needed for reasonable preparation, the bait is easy to unhook when too much water is added, and the bait is not easy to swallow when caking is caused when too little water is added; in addition, reasonable preparation of the bait is important, the food calling performance of the bait relates to the vision, smell and taste of fishes, the bait is closer to the shape of a natural true bait, the fishing effect is better, the dry powder or granular bait is prepared by mixing powder materials such as krill powder, fish meal and the like with spices such as clove and the like, the shape and the fragrance of the bait are greatly different from those of the natural true bait, particularly, the content of natural fish and shrimp flavor substances and a natural food calling agent trimethylamine oxide contained in the powder materials such as the krill powder, the fish meal and the like is reduced after multiple processing, the powder materials are converted into the trimethylamine with fishy smell, although the fishy smell can be covered by adding essence components to a certain degree, most of fishes are sensitive to the change of the smell, and according to experiments, the sensitivity of the fish for sensing the change of the concentration of the granulated sugar is 512 times higher than that of people, so that the certain amount of the trimethylamine can reduce the food calling performance of the bait to a certain degree.
Disclosure of Invention
Based on the problems existing in the background technology, the invention aims to provide the complete krill type bait capable of being directly used and the preparation method thereof.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
a whole krill type bait capable of being directly used is characterized by comprising the following components in parts by weight:
30-50 g of whole krill, 30-50 g of water, 5-10 g of absolute ethyl alcohol, 5-10 g of sodium chloride,
5 to 10 grams of trehalose, 0.5 to 4 grams of sodium alginate, 0.015 to 0.035 grams of carmine,
0.005-0.025 g of sunset yellow and 0.03-0.07 g of green apple liquid essence (YJS 060).
The invention further discloses a preparation method of the whole krill type bait capable of being directly used, which is characterized by comprising the following steps:
(1) ultraviolet light oxidation treatment: rinsing fresh krill or rehydrated krill, removing surface impurities, draining, and performing photo-oxidation treatment under 200-280 nm ultraviolet light for 30-60 min to remove trimethylamine which is a fishy substance in the krill and improve the fresh taste of the krill;
(2) blending anti-freezing components: firstly, uniformly mixing absolute ethyl alcohol and water (reducing freezing point, resisting freezing, increasing aroma and inhibiting bacteria), then adding uniformly mixed sodium chloride, trehalose and sodium alginate powder, and continuously stirring until the mixture is in a gel state to prepare a gel-like anti-freezing component;
(3) blending: adding pigment into krill, stirring, standing for 2-5 min, removing carmine and sunset yellow on surface, adding the gel component prepared in step (2) and green apple liquid essence, mixing, bagging, and storing under freezing condition.
The invention further discloses the application of the directly used whole krill type bait in enhancing the delicate flavor of the bait and removing the fishy smell. Especially the application of effectively prolonging the preservation time of the bait. The experimental result shows that after the bait is stored for 12 months at the temperature of-5 ℃, the ratio of the trimethylamine content to the trimethylamine oxide content is lower, the delicate flavor is better maintained, the volatile basic nitrogen content is 18.73mg/100g and is far lower than the putrefaction critical value by 30mg/100g, the food calling performance is 96 tailings/10 minutes, and the food calling performance is improved by 31.5 percent compared with the conventional bait.
The invention mainly solves the problem of developing the bait which is similar to the natural true bait form and can be directly used by using the intact krill, mainly considers the indexes of the bait such as the delicate flavor, the freshness, the food calling property and the like, and has the main difficulty that the indexes such as the delicate flavor and the like are still better maintained after the bait is stored for a long time in a low-temperature non-freezing state.
The main control indexes of the intact krill bait for direct use disclosed by the invention are as follows
(1) Does not freeze at the low temperature of minus 5 ℃;
(2) the fresh taste can be kept for 12 months at the temperature of minus 5 ℃, the freshness can be kept better, and the food is not decayed;
(3) the food calling performance is still high after the food is kept for 12 months at the temperature of minus 5 ℃.
The directly-usable whole krill type bait and the preparation method thereof disclosed by the invention have the positive effects that:
(1) the ultraviolet light oxidation treatment can effectively promote the oxidation of trimethylamine to generate the trimethylamine oxide which is a natural fish and shrimp delicate flavor substance, increase the delicate flavor of the bait and remove the fishy smell.
(2) The whole shrimps are adopted and dyed, so that the bait form is closer to the natural true bait form and is easier to identify.
(3) After the anti-freezing component is added, the bait is in a gel state at normal temperature and low temperature, can be directly used without thawing, and can be randomly shaped in size and shape; the bait has smooth surface and is easy to swallow by fishes; can be stored at low temperature for 12 months.
