Problems solved by technology

Using acid to extract gelatin can shorten the gel-making cycle and increase the extraction rate, but excessive acid action will lead to abnormal breakage of the covalent bonds of collagen molecules, destroy the integrity of collagen subunits, and then affect the quality of the finished gelatin

Embodiment 1

[0029] A kind of method that acid method produces pigskin gelatin, is made by following steps:

[0030] 1) Pretreatment: take fresh pigskin, clean it, depilate it, cut it into small pieces no larger than 4×4mm, add it to a sodium chloride solution with a mass fraction of 5%, soak it at 35°C for 4 hours, wash it with water to remove chlorine Sodium chloride is used to pretreat pigskin;

[0031] 2) Activation: Add the pretreated pigskin to the activation solution, soak it at 40°C for 3 hours, raise the temperature to 93°C, keep it for 4 minutes, cool it down to room temperature naturally, wash it with water, and control the moisture to obtain activated pigskin;

[0032] Said, the activation solution is prepared from the following raw materials in parts by weight: 3 parts of potassium chloride, 2 parts of sodium polyglutamate, 3 parts of citric acid, and 100 parts of water.

[0033] As mentioned, the weight ratio of pretreated pigskin and activation solution is 1:3.

[0034] 3)...

Embodiment 2

[0043] A kind of method that acid method produces pigskin gelatin, is made by following steps:

[0044] 1) Pretreatment: take fresh pigskin, clean it, depilate it, cut it into small pieces no larger than 4×4mm, add it to a sodium chloride solution with a mass fraction of 3%, soak it at 40°C for 5 hours, wash it with water to remove chlorine Sodium chloride is used to pretreat pigskin;

[0045] 2) Activation: Add the pretreated pigskin to the activation solution, soak it at 35°C for 2 hours, raise the temperature to 95°C, keep it for 3 minutes, cool it down to room temperature naturally, wash it with water, and control the moisture to obtain activated pigskin;

[0046] Said, the activation solution is prepared from the following raw materials in parts by weight: 5 parts of potassium chloride, 1 part of sodium polyglutamate, 4 parts of citric acid, and 100 parts of water.

[0047] As mentioned, the weight ratio of pretreated pigskin and activation solution is 1:2.

[0048] 3) ...

Embodiment 3

[0057] A kind of acid method is produced the method for pigskin gelatin, is made by following steps:

[0058] 1) Pretreatment: take fresh pigskin, clean it, depilate it, cut it into small pieces no larger than 4×4mm, add it to a sodium chloride solution with a mass fraction of 7%, soak it at 30°C for 3 hours, wash it with water to remove chlorine Sodium chloride is used to pretreat pigskin;

[0059] 2) Activation: Add the pretreated pigskin to the activation solution, soak it at 45°C for 2-4 hours, raise the temperature to 90-95°C, keep it for 3-5 minutes, cool it down to room temperature naturally, wash it with water, and dry it to get the activated pig Skin;

[0060] Said, the activation solution is prepared from the following raw materials in parts by weight: 1-5 parts of potassium chloride, 1-3 parts of sodium polyglutamate, 2-4 parts of citric acid, and 100 parts of water.

[0061] Said, the weight ratio of the pretreated pigskin and the activation solution is 1:2-4.

Abstract

The invention discloses a method for producing pigskin gelatin by an acid method, which is prepared by the following steps: pretreatment; activation; primary acidification; accelerated activation; secondary acidification and posttreatment. The invention significantly improves the extraction rate of gelatin through two times of acidification, so that the extraction rate reaches more than 85%, and has less waste water discharge and low cost, laying a good foundation for industrial scale production. Through activation, the tissue structure of pigskin is improved, and the acidification gel extraction process is promoted; in the first acidification, the temperature is continuously raised to shorten the acidification time, and the gelatin extraction rate is improved; and then through the activation, the gel strength of gelatin is improved; finally, through the secondary acidification, further The gel strength and viscosity of gelatin are enhanced, and the prepared gelatin has excellent properties.

Description

technical field [0001] The invention belongs to the technical field of gelatin preparation, in particular to a method for producing pigskin gelatin by an acid method. Background technique [0002] Gelatin (Gelatin) is the collagen contained in animal skin, bone, cartilage, ligament, sarcolemma, etc., which is a polymer of high-molecular polypeptide obtained after purification and primary hydrolysis, so it is also called animal gelatin and fat glue. . Gelatin is insoluble in cold water, but can slowly absorb water and swell to soften. Gelatin can absorb water equivalent to 5 to 10 times its weight. Gelatin is a low-calorie health food with high nutritional value. Gelatin shows multifunctionality in processing, heat conversion of glue, and combination with other ingredients, which can improve the elasticity, viscosity and stability of food. It can be used To make candy additives, frozen food additives, etc. In addition, in the industry, gelatin is also an indispensable raw ...
