Embodiment 1

[0030] A low-temperature fresh microfrozen liquid is composed of the following components by weight fraction: 18 parts of sodium chloride; 30 parts of glycerol; 14 parts of erythritol; and 38 parts of water.

[0031] The micro-freezing method of low-temperature fresh and alive micro-frozen liquid, 18 parts by weight of sodium chloride; 30 parts of glycerol; 14 parts of erythritol; In the micro-freezing chamber, after the temperature of the micro-freezing liquid drops to -38°C, the micro-freezing liquid is still liquid and not frozen; wash the salvaged crucian carp and put it directly into the micro-freezing liquid for 2 hours; The frozen objects after freezing were transferred to the heat preservation bin for storage, and the surface temperature and internal tissue temperature of the frozen matter stored in the heat preservation bin were both maintained at -5°C. Under this condition, the fresh crucian carp was taken out after 6 months, and the The quality is basically unchange...

Embodiment 2

[0033] A low-temperature fresh microfrozen liquid is composed of the following components by weight fraction: 8 parts of sodium chloride; 15 parts of glycerol; 10 parts of erythritol; and 67 parts of water.

[0034] The micro-freezing method of low-temperature fresh and alive micro-frozen liquid, by weight parts with 8 parts of sodium chloride; 15 parts of glycerol; 10 parts of erythritol; In the micro-freezing chamber, after the temperature of the micro-freezing liquid drops to -5°C, the micro-freezing liquid is still liquid and not frozen; wash the salvaged crayfish and directly put them into the micro-freezing liquid for 2.5 hours; The slightly frozen frozen objects are transferred to the thermal insulation bin for storage, and the surface temperature and internal tissue temperature of the frozen objects stored in the thermal insulation bin are both maintained at -3°C. Under this condition, the chilled crayfish will be taken out after 6 months. The measured quality is basic...

Embodiment 3

[0036] A low-temperature fresh microfrozen liquid is composed of the following components by weight fraction: 17 parts of sodium chloride; 21 parts of glycerol; 0.1 parts of chitin, 9 parts of erythritol; and 52.9 parts of water.

[0037] The micro-freezing method of low-temperature fresh and alive micro-frozen liquid, 17 parts by weight of sodium chloride; 21 parts of glycerol; 0.1 part of chitin, 9 parts of erythritol; Place the micro-freezing liquid in the micro-freezing chamber. After the temperature of the micro-freezing liquid drops to -35°C, the micro-freezing liquid is still liquid and not frozen; wash the salvaged prawns and put them directly into the micro-freezing liquid for micro-freezing. Freeze for 1.5 hours; the slightly frozen frozen objects are transferred to the insulation bin for storage, and the surface temperature and internal tissue temperature of the frozen objects stored in the insulation bin are both maintained at -5°C. Under this condition, after 6 mon...

Abstract

The invention relates to a low temperature fresh micro-freezing liquid and a micro-freezing method and applications, belonging to the technical field of product preservation. The low temperature freshmicro-freezing liquid is composed of the following components: sodium chloride, glycerol, erythritol, water, and auxiliary additives. The micro-freezing method comprises the following steps of: preparing the micro-freezing liquid from the sodium chloride, glycerol, erythritol, water, and auxiliary additives according to a ratio, placing the micro-freezing liquid in a micro-freezing tank, puttingan object to be frozen into the micro-freezing liquid for 1.5-2.5 hours After the temperature of the micro-freezing liquid drops to minus 5 - minus 38 DEG C, and transferring the frozen object to a heat preservation tank for storage. The low temperature fresh micro-freezing liquid can maintain quality, color, texture and related sensory indexes of all kinds of products, reduce the formation of icecrystal in the product tissue during freezing at low temperature, inhibit enzyme activity and propagation of spoilage microorganisms in the tissue, and can better maintain integrity of product tissuecells.

Description

technical field [0001] The invention relates to the technical field of product preservation, in particular to a low-temperature fresh micro-frozen liquid and a micro-freezing method and application. Background technique [0002] Currently commercially available frozen aquatic products are usually frozen in a freezing chamber, which is frozen in a freezing chamber at -35°C to -30°C, but it takes a long time to freeze, and generally takes 6-8 hours to achieve freezing However, long-term slow dehydration and dry consumption will seriously affect the cell structure of aquatic products, causing serious damage to the cells of aquatic products when returning to normal temperature, and affecting the taste when eating. According to relevant reports, after 10,000 tons of fish enter the city from the place of origin, only about 3,000 tons are edible, and the remaining 7,000 tons become garbage. Of the 10,000 tons of shrimp entering the city, 5,000 tons are garbage. This is enough to ...
