Problems solved by technology

[0004] The present invention is to solve the production method of dried Antarctic krill products in the prior art. In order to ensure the storage period of Antarctic krill products, the water content of Antarctic krill can only be reduced to 18-20%, resulting in dry shrimp body of Antarctic krill. Hard, poor taste, and brittle, it provides a reasonable compatibility, each component cooperates with each other, does not affect the nutritional content, flavor and color of dried Antarctic krill, non-toxic and safe, easy to obtain raw materials, and low cost , high efficiency, broad spectrum, good stability, can effectively prolong the storage period of dried Antarctic krill products under the condition of increasing the moisture content of Antarctic krill dried Antarctic krill preservative

Embodiment 1

[0021] (1) prepare bamboo leaf extract: fresh bamboo leaf is placed in extraction tank, adding 8 times of the mass content of bamboo leaf quality is the ethanolic solution of 85%, regulating extraction tank pressure is 2.5MPa, after being warming up to 32 ℃, Extraction with the aid of ultrasonic waves with a frequency of 60KHz for at least 3h; filter the obtained extract to obtain a filtrate; place the filtrate in a vacuum concentration tank, and concentrate at 4°C until it becomes a paste to obtain a concentrated paste; Carry out low temperature drying, pulverize and pass through a 150 mesh sieve to obtain the bamboo leaf extract;

[0022] (2) Compounding: weighed according to the weight ratio of 4g calcium propionate, 4g natamycin, 12g bamboo leaf extract, 0.4g vitamin C, 4g sodium lactate, 0.7g sodium EDTA, 2g malic acid After each component, mix each component uniformly to obtain Antarctic krill dry preservative.

Embodiment 2

[0024] (1) prepare bamboo leaf extract: fresh bamboo leaf is placed in extraction tank, adding 7 times of the mass content of bamboo leaf quality is 80% ethanol solution, regulating extraction tank pressure is 2MPa, after being warming up to 30 ℃, with Ultrasonic-assisted extraction with a frequency of 50KHz for at least 3h; filter the obtained extract to obtain a filtrate; place the filtrate in a vacuum concentration tank, and concentrate at 3°C ​​until it becomes a paste to obtain a concentrated paste; Dry at low temperature, pulverize and pass through a 150-mesh sieve to obtain the bamboo leaf extract;

[0025] (2) Compounding: weighed according to the weight ratio of 3g calcium propionate, 3g natamycin, 10g bamboo leaf extract, 0.3g vitamin C, 3g sodium lactate, 0.5g sodium EDTA, 1g malic acid After each component, mix each component uniformly to obtain Antarctic krill dry preservative.

Embodiment 3

[0027] (1) prepare bamboo leaf extract: fresh bamboo leaf is placed in extraction tank, adding 10 times of the mass content of bamboo leaf quality is 90% ethanol solution, regulating extraction tank pressure is 3MPa, after being warming up to 35 ℃, with Ultrasonic-assisted extraction with a frequency of 70KHz for at least 3h; filter the obtained extract to obtain a filtrate; place the filtrate in a vacuum concentration tank, and concentrate at 5°C until it becomes a paste to obtain a concentrated paste; Dry at low temperature, pulverize and pass through a 150-mesh sieve to obtain the bamboo leaf extract;

[0028] (2) Compounding: take by weighing the weight ratio of 5g calcium propionate, 5g natamycin, 15g bamboo leaf extract, 0.5g vitamin C, 5g sodium lactate, 1g sodium EDTA, 3g malic acid. After the components are combined, the components are mixed uniformly to obtain Antarctic krill dry preservative.

Abstract

The invention discloses a preservative for dried Euphausia superb. The preservative comprises, by weight, 3 to 5 parts of calcium propionate, 3 to 5 parts of natamycin, 10 to 15 parts of bamboo leaf extract, 0. 3 to 0.5 part of vitamin C, 3 to 5 parts of sodium lactate, 0.5 to 1 part of sodium ethylenediaminetetraacetate and 1 to 3 parts of malic acid. The preservative for dried Euphausia superb of the invention is reasonable in compatibility of components, and all the components cooperate with each other; the preservative does not affect the nutrient composition, flavor and color of Euphausiasuperb, is non-toxic and safe, uses easily available raw materials, has low cost, high efficiency, broad spectrum and good stability, and can effectively prolong the storage period of dried Euphausiasuperb while improving the moisture content of dried Euphausia superb. The invention also discloses a preparation method for the preservative. The preparation method comprises the following steps: (1) preparation of the bamboo leaf extract; and (2) compounding. The preparation method of the invention has the advantages of simple process steps, good operability, low requirements on equipment, andsuitability for industrial production.

Description

technical field [0001] The invention relates to a preservative, in particular to an Antarctic krill dry preservative and a preparation method and application thereof. Background technique [0002] Antarctic krill is usually the guide giant krill, which belongs to the genus Krillaceae Krill, the order Crustacea of ​​the Arthropoda phylum Crustacea. Antarctic krill itself also contains rich protein, mineral elements and a variety of unsaturated fatty acids such as EPA, DHA, etc., which have good medical and health care functions for the human body. In addition, Antarctic krill also contains a variety of active ingredients, such as enzymes, chitin and astaxanthin, etc. These substances are conducive to the development of high value-added products of Antarctic krill and greatly improve the comprehensive utilization of Antarctic krill resources Rate. At present, the main product forms of Antarctic krill are Antarctic krill meal and Antarctic krill oil, in addition to primary pr...
