Embodiment 1

[0021] A kind of preparation method of pigskin collagen frozen food provided by the present embodiment, it comprises the steps:

[0022] 1) Preparation of pigskin collagen:

[0023] 1.1) Pretreatment of pigskin raw materials: remove blood from fresh pigskin, degrease, rinse with distilled water, dry and set aside;

[0024] 1.2) Extraction of pigskin collagen: put the above-mentioned pretreated pigskin into a temperature-controlled furnace, add enzyme and acetic acid solution for hydrolysis, control the temperature at 3°C, stir slowly for 4 days, then centrifuge, and take the supernatant solution, Prepare crudely extracted collagen solution;

[0025] 1.3) Purification of pigskin collagen: Slowly add 6mol / L sodium hydroxide solution to the crude collagen solution to adjust the pH value to 7. Under the condition of 3°C, freeze and centrifuge to remove the precipitate, and add Grind sodium chloride solid into fine powder, stir slowly, keep standing at 3°C ​​for 1d; centrifuge to...

Embodiment 2

[0038] A kind of preparation method of pigskin collagen frozen food provided by the present embodiment, it comprises the steps:

[0039] 1) Preparation of pigskin collagen:

[0040] 1.1) Pretreatment of pigskin raw materials: remove blood from fresh pigskin, degrease, rinse with distilled water, dry and set aside;

[0041] 1.2) Extraction of pigskin collagen: crush or chop the above-mentioned pretreated pigskin with a shredder, put it into a temperature-controlled furnace, add enzyme and acetic acid solution for hydrolysis, control the temperature at 3°C, Stir slowly for 4 days, then centrifuge at 3000r / min, take the supernatant solution, and prepare a crude collagen solution; to remove peculiar smell, add 1% white wine and 1% white vinegar in a volume ratio to the crude collagen solution, and let it stand for 2 hours.

[0042] 1.3) Purification of pigskin collagen: Slowly add 6mol / L sodium hydroxide solution to the crude collagen solution to adjust the pH value to 7. Under t...

Embodiment 3

[0054]Embodiment 3 is basically the same as Embodiment 2, and its difference is:

[0055] Step 2) Preparation of pigskin collagen frozen food:

[0056] 2.1) Weigh the components in the following weight ratios:

[0057]

[0058] Among them, the yam powder is dry-fried and dehydrated at 70°C.

[0059] 2.2) Dissolve pigskin collagen, yam powder and carrageenan in 500g of water, boil and add hawthorn powder, tangerine peel powder and citric acid to prepare;

[0060] 2.3) Add konjac flour and sodium carbonate to 350g of water and heat. When the water temperature is 70°C, add lysine, heme and vitamin A respectively, stir for 8 minutes, keep heating in a water bath at 90°C for 70 minutes, and add to the mixture after gelling The good pigskin collagen is stirred evenly while it is hot, cooled and finalized, and the frozen food of pigskin collagen is obtained.

[0061] In addition, in step 2.1), 15g of cellulose with the following weight ratio can also be included; and in step 2....

Abstract

The invention discloses a preparation method of a pigskin collagen jelly food. The preparation method is characterized by comprising the following steps: 1) preparing the pigskin collagen: 1.1) pretreating the pigskin raw material, 1.2) extracting the pigskin collagen, and 1.3) purifying the pigskin collagen; 2) preparing the pigskin collagen jelly food pigskin collagen jelly food: 2.1) weighing components in parts by weight, 2.2) dissolving the pigskin collagen, yam flour and carrageenan in 40-60 parts of purified water, boiling, and then adding hawthorn powder, dried orange peel powder and citric acid; 2.3) dissolving konjaku flour and sodium carbonate in the rest purified water and heating, adding lysine, heme and vitamin A, respectively, gelatinizing and then adding the prepared pigskin collagen, evenly stirring while hot, and then cooling and setting, thereby obtaining the pigskin collagen jelly food. The invention also discloses the pigskin collagen jelly food prepared by the method. The pigskin collagen jelly food is added with yam, hawthorn, dried orange peel, cellulose and the like, and thus tastes fragrant and sweet and is capable of promoting the appetite.

Description
