Technical Field

The invention relates to the field of biology, in particular to a bait preservative and application thereof.

Background

Bait, i.e. food eaten by fish. The bait is food for attracting fishes to hook during fishing, and is further all usable substances capable of gathering fishes or attracting fishes to hook during fishing.

There are two forms of current commercially available baits: a powder is mainly prepared from dry powder and liquid substance by mixing. The fresh-keeping problem does not need to be considered, but the fresh-keeping effect is poor in convenience during use, and the effect of convenient use and storage resistance is difficult to achieve. One is a mixed cake, which can be used directly. It is made up by using beans, grain and flour as main body, and adding small quantity of fish powder, earthworm powder, yeast extract, colloid and rapeseed oil, etc. through a certain preparation process. The component material is not resistant to normal temperature storage, so the refrigeration is mainly used, and the component material needs to be used within 1-2 days after being thawed. Therefore, the product formula for providing the fish bait preservative and the processing mode for preserving the fish bait have important practical significance.

Disclosure of Invention

In view of the above, the invention provides a natural preservative formula for keeping fish bait fresh, and provides a processing mode capable of prolonging the shelf life of the fish bait by analyzing the material characteristics of the fish bait. Therefore, the wet bait is beneficial to storing the wet bait, and the problem of convenient use is also solved.

In order to achieve the above object, the present invention provides the following technical solutions:

the invention provides a bait preservative which comprises the following components in parts by mass:

20-60 parts of lauric acid arginine ethyl ester hydrochloride

10-30 parts of sodium lactate

1-10 parts of ursolic acid.

In some embodiments of the invention, the bait preservative further comprises 0.1-10 parts by mass of citral.

In some embodiments of the invention, the bait preservative further comprises 0.1-10 parts by mass of chitosan.

Lauric acid arginine ethyl ester hydrochloride: is derived from natural substances such as L-arginine and lauric acid, and is a cationic surfactant. It can act on the cell membrane of an organism to change the permeability of the membrane, thereby playing a remarkable role in inhibiting bacteria, yeast and mold. It can be decomposed into compounds commonly existing in daily diet through biochemical metabolic pathway in human body, and has high safety.

Sodium lactate: has strong hygroscopicity, can absorb free water in the bait, effectively reduces the water activity of the bait, and inhibits the growth and reproduction of microorganisms. Meanwhile, the bait can prevent water loss, and can play a role in high-efficiency moisture preservation under a low-temperature and dry state, so that the flavor of the bait is kept.

Ursolic acid: is a kind of triterpenoid compound existing in natural plants, and has antiinflammatory, antibacterial and antioxidant effects.

And (3) chitosan: the antibacterial natural high polymer is nontoxic, has certain effect on cell walls and cell membranes of bacteria, increases the permeability of the bacteria, and causes the outflow of cytoplasmic substances to achieve the antibacterial effect.

Citral: is a good antibacterial spice.

The traditional bait corrosion prevention mainly comprises the steps of freezing storage, or dry powder storage and subsequent water adding and mixing, or the processes of cultivation, fermentation and the like are proposed by the prior patent through biotechnology. These methods either limit the storage conditions or require a complicated process. The raw materials such as lauric acid arginine ethyl ester hydrochloride, sodium lactate, chitosan, ursolic acid, citral and the like are selected for composite use, and the reason is that:

the three raw materials of chitosan and ursolic acid can play a role through cell membranes of organisms, so that the permeability of the cell membranes is changed, once the medium of substances inside and outside the cells is changed, the organisms cannot normally grow and metabolize, and the effect of jointly inhibiting bacteria and killing bacteria is achieved;

secondly, the sodium lactate can lock water, prevent the bait from being dried to lose flavor and taste, and can reduce the water activity of the bait. Since the activity of microorganisms is related to the water activity of food, a specific microorganism can grow only when the water activity of food is greater than a certain critical value. Therefore, the water activity of the food is controlled, so that the growth and the propagation of microorganisms can be effectively controlled;

③ the raw materials of the allowed preservative in the common food are mostly chemically synthesized, which has safety problem, and the preservative substances need a relatively acid environment to exert good preservative effect. However, the bait is specially prepared, and various raw materials are easy to deteriorate under an acidic condition. The flavor of the product is extremely easy to influence.

The formula provided by the invention selects natural raw materials, so that the food safety problem is avoided. And the raw materials are mutually superposed, so that a better synergistic anticorrosion effect can be exerted. Meanwhile, the sodium lactate can synergistically reduce the water activity of the formula, inhibit the growth of microorganisms, lock water and keep good taste of the bait. The raw materials are mutually overlapped, and can better exert good bacteriostatic and bactericidal effects.

The packaged bait is recommended to be sterilized in high-temperature water bath or high pressure after being vacuumized, and is suitable for the bait formula with high content of starch and coarse grain raw materials. Part of pathogens have the characteristic of heat resistance, so most of thermolabile bacteria or bacterial spores can be effectively inhibited after high-temperature sterilization.

In a word, the good fresh-keeping effect can be achieved only by combining the internal and external bacteriostasis and sterilization.

The invention also provides application of the bait preservative in preparation of bait.

On the basis of the research, the invention also provides the bait, which comprises the bait preservative, acceptable raw materials and auxiliary materials.

In some embodiments of the present invention, the bait preservative in the bait is 0.1% to 1% by weight.

The invention also provides a preparation method of the bait, which comprises the step of treating the bait preservative, acceptable raw materials and auxiliary materials for 5-30 min in a high-temperature water bath at 80-100 ℃ or under the vacuum high-pressure condition of 121 ℃ and 0.1 MPa.

The beneficial effects of the invention include but are not limited to:

(1) provides a product formula of the fish bait preservative and a processing mode for fish bait preservation;

(2) natural preservative substances are used as a product formula, so that the harm to human health and environment is avoided, and a good fresh-keeping effect is achieved;

(3) the shelf life of the bait is prolonged, so that the bait has the characteristics of convenience in use, transportation and storage resistance;

(4) the processed bait still keeps good flavor after being stored for more than 1 month at normal temperature (about 20 +/-5 ℃ and humidity of 40-60%) under the condition of not opening the mouth.
