preparation example Construction

[0026] A preparation method based on a shell powder-based aquatic product preservative, comprising the following steps:

[0027] Step 1, the preparation of micronano shell powder:

[0028] Wash the shells first, and then use the concentration of 0.3wt%-1wt% (for example, in 0.3%, 0.4%, 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, etc. or between any two) value) of hydrochloric acid solution or concentration of 0.5wt%-1wt% (such as in 0.5%, 0.6%, 0.7%, 0.8%, 0.9%, 1%, etc. or any value between the two) sodium hydroxide solution Desalting and degreasing the washed shells to obtain desalted and degreased shells; the desalting and degreasing treatment is: soak the washed shells with the above hydrochloric acid solution or sodium hydroxide solution for 30-60 minutes (such as 30 minutes, 35 minutes, 40min, 50min, 55min, 60min, etc. or any value between the two), preferably 45min; the shell is one or more of mussels, scallops, oyster shells, river clam shells, flower shells, etc.; desalination...

Embodiment 1

[0042]Among the raw materials of the fresh-keeping agent for aquatic products in this embodiment, the weight-to-number ratio of micronano shell powder, deionized water, and natural thickener is 0.2:100:4.

[0043] (1) Wash the shells first, and then use a hydrochloric acid solution with a concentration of 0.5wt% to desalt and degrease the washed shells: soak for 45 minutes to obtain desalted and degreased shells, and then dry or dry to obtain dry shells. a shell; the shell is a mussel;

[0044] (2) The dried shells are coarsely pulverized by a pulverizer to obtain coarse shell powder with an average particle diameter of about 1 mm;

[0045] (3) Carry out high-temperature calcining and puffing treatment of shell coarse powder in a high-temperature resistance furnace or a muffle furnace at 800°C for 4 hours to obtain a calcined coarse powder; then slowly cool in a drying oven to room temperature to obtain a cooled coarse powder. powder;

[0046] (4) The cooled coarse powder is...

Embodiment 2

[0052] Among the raw materials of the fresh-keeping agent for aquatic products in this embodiment, the weight-to-number ratio of micro-nano shell powder, deionized water, and natural thickener is 0.3:100:1.75.

[0053] (1) Wash the shells first, and then use a sodium hydroxide solution with a concentration of 0.6wt% to desalt and degrease the washed shells: soak for 32 minutes to obtain desalted and degreased shells, and then dry or dry to obtain dried shells; the shells are scallops;

[0054] (2) The dried shells are coarsely pulverized by a pulverizer to obtain coarse shell powder with an average particle size of 0.5 mm;

[0055] (3) Carry out high-temperature calcining and puffing treatment of shell coarse powder in a high-temperature resistance furnace or a muffle furnace at 900°C for 4 hours to obtain calcined coarse powder; then slowly cool in a drying oven to room temperature to obtain the cooled coarse powder. powder;

[0056] (4) The cooled coarse powder is subjecte...

Abstract

The invention discloses a preparation method of an aquatic product fresh-keeping agent based on shell powder. The preparation method comprises the following steps of preparing micro nanometer shell powder; sequentially performing desalting and degreasing treatment, drying treatment, coarse grinding treatment, calcining and expanding treatment, cold treatment and micro nanometer crushing treatment on shells so as to obtain the micro nanometer shell powder; adding a natural thickener: adding water and the natural thickener to the micro nanometer shell powder, and performing mixing so as to obtain the aquatic product fresh-keeping agent. The aquatic product fresh-keeping agent prepared by the method disclosed by the invention can be rapidly adhered to the surfaces of the aquatic products, has favorable sterilizing and fresh-keeping properties, is natural and harmless, and is a promising purely natural aquatic product fresh-keeping agent.

Description

technical field [0001] The invention belongs to the field of food fresh-keeping agents, and in particular relates to a preparation method of an aquatic product fresh-keeping agent based on shell powder, which uses natural shells as main raw materials and has good fresh-keeping effect. Background technique [0002] Aquatic products such as fish, shrimp, crab, and shellfish are indispensable foods in people's daily life. They are rich in nutritional value and are good sources of high-quality protein, unsaturated fatty acids, vitamins, and inorganic salts. Therefore, it is very important to inhibit or delay the spoilage and deterioration of fresh aquatic products and maintain their good freshness and quality. [0003] At present, the commonly used technologies for fresh-keeping of aquatic products include low-temperature preservation, chemical substance treatment, biologically active substance treatment, modified atmosphere and gas preservation, and irradiation preservation. U...
