Embodiment 1

[0019] (1) Select fresh fish maw, and remove the fat, blood vessels, nerves and other tissues on the surface of the swim bladder;

[0020] (2) Cut the swim bladder into filaments with a width of 0.2cm;

[0021] (3) Soak with 1% NaOH solution for 5 hours, rinse with tap water until nearly neutral;

[0022] (4) Under 40°, dry the fish maw shreds with hot air for 24 hours, and the water content is 13.5%;

[0023] (5) The dried fish maw shreds are pulverized to a particle size of 80 meshes, and the finished fish maw gel is packaged.

Embodiment 2

[0025] (1) Select fresh fish maw, and use a knife to remove fat, blood vessels, nerves and other tissues on the surface of the swim bladder;

[0026] (2) Cut the swim bladder into filaments with a width of 1.0cm;

[0027] (3) with 6% Na 2 CO 3 The solution was soaked for 3 hours, rinsed with tap water until nearly neutral;

[0028] (4) Under 40°, dry the fish maw shreds with hot air for 20 hours, and the water content is 14%;

Abstract

The invention discloses a processing method of fish glue, which is characterized by including the following steps: fresh fish maws are selected; the tissues such as fat, blood vessels, nerves and the like on the surface of the fish maws are removed; the fish maws are cut into filaments with the width of 0.2cm to 1.0cm and dipped in NaOH solution of 1 to 3 percent (weight percentage concentration) or Na2CO3 solution of 2 to 6 percent (weight percentage concentration) for 3 to 5 hours and then washed by tap water for approaching neutral; then the filaments of the fish maws are dried under temperature below 40 DEG C for containing less than 14 percent of water or frozen-dried until the water content is less than 14 percent; and the filaments of the fish maws after being dried are cracked and packaged, thus being the finished product of the fish glue. The processing method of fish glue has the advantages that: the fish glue can be used as medical engineering materials, edible packaging materials, a cosmetic raw materials, beer clarifiers, sherry clarifiers, or water processing clarifiers and the raw materials of health care food.

Description

technical field [0001] The invention relates to the fields of aquatic product processing and preparation of natural polymer materials, in particular, isinglass and its processing method. Background technique [0002] The basic composition of swim bladder is composed of 76.28% to 79.28% protein, 0.17% to 4.34% fat, 17.95% to 20.86% water and 0.25% to 0.99% ash (Duan Zhenhua et al., Analysis and evaluation of nutritional components of several swim bladders [J] Food Research and Development, 2007.28(10): 62~65.). It can be seen that the swim bladder is mainly composed of protein, most of which is collagen fibrous protein, so the swim bladder is a good raw material for producing collagen biomaterials. But, prior art, only fish maw is developed as food raw material, as, the swim bladder glue that Chen Yunti (invention patent 96122976.4) is raw material processing with fish maw, new donkey-hide gelatin, rock sugar, peanut oil, yellow rice wine, has solid type, concentrated Liqui...
