Embodiment 1

[0033] Combined use of hydrogen peroxide and ultraviolet treatment to prepare sheepskin collagen casings, the process route is as follows: the raw sheepskin is cleaned by soaking in water, liming and depilation, hydrogen peroxide treatment, first pickling, mincing and beating, compounding, secondary acidification, homogeneous filtration, extrusion The sheepskin collagen casings were prepared by curing, washing and plasticizing, ultraviolet cross-linking and drying and humidifying.

[0034] The specific steps are:

[0035] (1) Raw sheepskin soaked in water for cleaning: Rinse the raw leather with grass thorns and hair with clean water until there is no sand in the leather water, soak in clean water at 15°C for 3 days, and change the water every 6 hours.

[0036](2) Liming and hair removal: 5% lime, 3% sodium sulfide and 10% water were mixed into a paste, evenly spread on the soaked sheepskin, and the hair was removed for 3 hours. Wash the sheepskin 4 times with water, soak it ...

Embodiment 2

[0048] In order to highlight the advantages of combined hydrogen peroxide and ultraviolet treatment, the hydrogen peroxide treatment in Example 1 is omitted to prepare sheepskin collagen casings. The process route is as follows: the raw sheepskin is washed by immersion, liming and depilation, peeling, pickling once, crushing and beating, and then Sheepskin collagen casings were prepared through compounding, secondary acidification, homogeneous filtration, extrusion curing, washing and plasticizing, ultraviolet crosslinking and drying and humidification.

[0049] The specific steps are:

[0050] (1) Raw sheepskin soaked in water for cleaning: Rinse the raw leather with grass thorns and hair with clean water until there is no sand in the leather water, soak in clean water at 15°C for 3 days, and change the water every 6 hours.

Embodiment 3

[0064] In order to highlight the advantages of combined hydrogen peroxide and ultraviolet treatment, omit the ultraviolet crosslinking treatment in Example 1 to prepare sheepskin collagen casings. The process route is: the raw sheepskin is washed by immersion, liming and depilation, hydrogen peroxide treatment, pickling once, minced Beating, compounding, secondary acidification, homogeneous filtration, extrusion curing, washing and plasticizing, drying and humidifying to obtain sheepskin collagen casings.

[0065] The specific steps are:

[0066] (1) Raw sheepskin soaked in water for cleaning: Rinse the raw leather with thorns and hair with clean water until there is no sand in the leather water, soak in clean water at 15°C for 3 days, and change the water every 6 hours.

Abstract

The invention discloses a preparation method of a sheepskin collagen casing. The preparation method comprises raw sheepskin immersion in water and washing, liming hair removal, hydrogen peroxide treatment, primary pickling, mincing and beating, compounding, secondary pickling, homogenization and filtration, extrusion and curing, water washing and plastification, UV crosslinking, drying and humidification. The preparation method realizes the comprehensive utilization of bur sheepskin, prevents the waste of resources and the pollution of the environment and can produce huge economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of sheepskin utilization, and in particular relates to a preparation method of sheepskin collagen casings. Background technique [0002] Casing is the packaging of enema products, an indispensable material in the molding process, and can keep the product quality stable during the shelf life, occupying an important position in the meat industry. With the sharp increase in the consumption of enema products, the demand for casings has also increased greatly, and artificial collagen casings have emerged as the times require, effectively making up for the shortage of natural casings. Artificial collagen casings are casing casings formed by separating and extracting collagen from animal skins, adding other ingredients, mixing and extruding evenly. After decades of development and continuous updating, the quality of collagen casings has become increasingly stable in industrial production, and its growth momentum i...
