preparation example Construction

[0028] A kind of preparation method of large yellow croaker preservative provided by the invention comprises the following steps:

[0029] Step 1: After stunning the freshly farmed large yellow croaker to death, scrape off and collect the mucus on the surface of the fish to obtain the mucus on the surface of the fish;

[0030] Step 2: Mix the fish body surface mucus in step 1 with sterile ice water to obtain diluted fish body mucus;

[0031] Step 3: Grinding and sieving the star anise, white pepper and cinnamon respectively, adding them to the diluted fish body mucus in step 2 and mixing in order to obtain the preservative for large yellow croaker.

[0032] It can be seen from the above description that the present invention has the following beneficial effects: the large yellow croaker antistaling agent of the present invention contains the surface mucus of the large yellow croaker itself, and in addition it interacts with other auxiliary materials, so the large yellow croake...

Embodiment 1

[0058] A fresh-keeping method for chilled large yellow croaker (a method for using a fresh-keeping agent for large yellow croaker), which comprises the following steps: after the fresh and live cultured large yellow croaker is stunned to death, the mucus on the surface of the fish body is scraped off and collected to obtain the mucus on the surface of the fish body; Mix the mucus on the surface of the fish body with sterile ice water at a mass ratio of 1:1 to obtain the diluted fish mucus, and then crush star anise, 0.02% white pepper and 0.1% cinnamon, which account for 0.2% of the mass of the diluted fish mucus, through 80 meshes respectively After sieving, add it to the diluted fish body mucus in turn to make a large yellow croaker preservative. Soak chilled large yellow croaker in large yellow croaker preservative for 30 minutes, then take it out, soak it in 8g / L chitosan solution for 30s, drain and form a film, sterilize for 90s under 20 w ultraviolet light, vacuum pack at...

Abstract

The invention provides a pseudosciaena crocea preservative, a preparation method and an application method thereof. The preparation method comprises the following steps: stunning fresh cultured pseudosciaena crocea to death, scraping off the mucus on the surface of the fish body and collecting to obtain the fish body mucus; mixing fish body mucus with sterile ice water to obtain diluted fish bodymucus; and respectively crushing and sieving illicium verum, white pepper and cinnamon, and then sequentially adding into the diluted fish body mucus and mixing to obtain the pseudosciaena crocea preservative. The application method comprises the following steps: soaking chilled pseudosciaena crocea in the pseudosciaena crocea preservative for 20-40min, then taking out, soaking in a chitosan aqueous solution for 25-35s, draining to form a film; and sterilizing the treated chilled pseudosciaena crocea by ultraviolet and vacuum-packaging. The prepared pseudosciaena crocea preservative can effectively prolong the shelf life of chilled pseudosciaena crocea, has no influence on the organoleptic quality of pseudosciaena crocea, is safe and harmless, improves the eating quality of the chilled pseudosciaena crocea, and is helpful to expand the sales areas of the chilled pseudosciaena crocea.

Description

technical field [0001] The invention relates to the technical field of fresh-keeping of aquatic products, in particular to a fresh-keeping agent for large yellow croaker and its preparation method and application method. Background technique [0002] large yellow croaker ( Pseudosciaenacrocea ), belongs to Osteichthyes, Perciformes, Totoaceae, Yellow Fish, also known as yellow croaker, Kingfish, Golden Dragon and so on. According to the "China Fishery Statistical Yearbook" in 2018, the production of large yellow croaker in my country reached 177,600 tons, of which Fujian Province produced 150,500 tons, accounting for 84.7% of the national total. The nutritional value of large yellow croaker is extremely high, and its amino acid composition is higher than the evaluation standard of the FAO / WHO ideal model. Studies have shown that the content of EPA+DHA is as high as 18.39%, which can reduce blood lipids and prevent cardiovascular and cerebrovascular diseases. [0003] Stud...
