Problems solved by technology

The above-mentioned biotechnology requirements are relatively high, and the conditions such as retention time and temperature of the activity of various preparations extracted are harsh, and it is difficult to master and control
In addition, the price and cost of biological preservatives are relatively high, which limits their popularization and application to a certain extent; some biological preservatives will cause changes in food color and flavor; aquatic products are generally stored at low temperatures, which will make biological preservatives The effect is limited

Embodiment Construction

[0048] In a plant-derived biological fresh-keeping liquid applied to aquatic products of the present invention, the effectiveness test of the main active ingredients is as follows:

[0049] Table 1 Determination of Ginger Extract Concentration Range

[0050]

[0051] Note: *, ** indicate significant difference at 0.05, 0.01 levels. The table below is the same.

[0052] Table 1 shows that ginger extract can significantly improve the anti-hypoxic ability of loach, river shrimp, and river crab at a concentration of 1.5‰, and can significantly improve the anti-hypoxia ability of loach, river shrimp, and river crab at a concentration of 0.8‰ and 2.5‰ . For crucian carp, ginger extract can significantly improve its anti-hypoxia ability at a concentration of 2.5‰, and can significantly improve its anti-anoxic ability at a concentration of 0.8‰ and 1.5‰. Finally, the concentration range of ginger extract is considered to be 1.5‰~2.5‰.

Abstract

The invention discloses plant-derived biological fresh-keeping alive-keeping liquid applied to aquatic products and a preparation method of the plant-derived biological fresh-keeping alive-keeping liquid. The technical scheme adopted by the invention lies in that the plant-derived biological fresh-keeping alive-keeping liquid consists of the following components in volume ratio concentration: 0.04-0.08% of membrane materials, 0.1-0.5% of an anaesthetic, 0.015% of a preservative, 0.4-1.0% of an oxygen deficit resistant agent, 0.2-0.8% of a bacteriostatic agent, 0.025% of active ferment and the balance of water. According to the plant-derived biological fresh-keeping alive-keeping liquid applied to aquatic products disclosed by the invention, active components of raw materials of the fresh-keeping alive-keeping liquid applied to aquatic products are all extracted from Chinese herbal medicines through a supercritical extraction technique, the Chinese herbal medicines having various special efficacy are screened, and effective components and plant essential oil in the Chinese herbal medicines are extracted. The invention further aims to provide the preparation method of the plant-derived biological fresh-keeping alive-keeping liquid applied to aquatic products.

Description

【Technical field】 [0001] The invention belongs to the technical field of fresh-keeping and storage of aquatic products, and in particular relates to a plant-derived biological fresh-keeping liquid applied to aquatic products and a preparation method thereof. 【Background technique】 [0002] The new technology of fresh-keeping aquatic products mainly includes three aspects: physical fresh-keeping, chemical fresh-keeping and biological fresh-keeping. [0003] Physical preservation methods can be divided into modified atmosphere preservation methods, low temperature preservation methods, ozone preservation methods and cold sterilization preservation methods, among which cold sterilization methods mainly include irradiation preservation methods, ultra-high pressure preservation methods and high-voltage pulse electric field preservation methods. [0004] The chemical preservation method is mainly to add anesthetics, preservatives, antibacterial agents and antioxidants to aquatic p...
