Embodiment 1

[0030] (1) Preparation of lubricant: with 3.2% sorbitan trioleate, 4.8% sorbitan monooleate, 2% soybean oil, 1% food grade paraffin oil, 1% batching (dibutyl 0.2% of hydroxytoluene, 0.2% of tert-butyl hydroxyanisole, 0.1% of propyl gallate, 0.1% of calcium sulfate, 0.2% of sodium polyphosphate, 0.2% of lactic acid) after mixing and stirring evenly, add to the aqueous solution containing 12% glycerin Stir evenly in medium, and disperse at a high speed for 5 minutes at 10000 rpm to obtain the emulsion lubricant according to the present invention. Among them, the viscosity of soybean oil mixed with food grade paraffin oil is 3.5 Pa.s, and the viscosity of the prepared lubricant is 0.05 Pa.s.

[0031] (2) Infiltration: After removing the content, flushing with water and soaking, infiltrate the pig original intestine with the lubricant prepared in step (1) for 10 minutes.

[0032] The breakage rate of pig casings has been reduced from the initial 10% to less than 1%.

Embodiment 2

[0034] (1) Preparation of lubricant: 4% sorbitan trioleate, 4% sorbitan monooleate, 2.5% corn oil, 0.5% food grade aromatic paraffin oil, 0.5% batching (dibutyl 0.2% of hydroxytoluene, 0.1% of propyl gallate, 0.1% of sodium polyphosphate, 0.1% of lactic acid) were mixed and stirred evenly, then added to the aqueous solution containing 15% glycerin and stirred evenly, and dispersed at a high speed of 10000rpm for 10min to obtain the present invention. lubricant, wherein the viscosity of corn oil mixed with food-grade aromatic oil is 2.5Pa.s, and the viscosity of the prepared lubricant is 0.04Pa.s.

[0035] (2) Soaking: After removing the content, flushing with water and soaking, soak the bovine gastritis with the lubricant prepared in step (1) for 15 minutes.

[0036] The breakage rate of cattle casings has been reduced from the initial 8% to less than 0.5%.

Embodiment 3

[0038] (1) Preparation of lubricant: with 5.6% sorbitan trioleate, 2.4% sorbitan monooleate, 1% lard, 2% food grade paraffin oil, 1% batching (dibutyl 0.2% hydroxytoluene, 0.2% tert-butyl hydroxyanisole, 0.1% propyl gallate, 0.1% calcium sulfate, 0.2% sodium carboxymethyl cellulose, 0.2% lactic acid) after mixing and stirring evenly, add to 8% glycerol Stir evenly in the aqueous solution of 10000rpm and disperse at a high speed for 5 minutes to obtain the emulsion type lubricant of the present invention. Among them, the viscosity of lard and food-grade paraffin oil is 6Pa.s after mixing, and the viscosity of the prepared lubricant is 0.09Pa.s.

[0039] (2) Infiltration: After removing the content, flushing with water and soaking, soak the sheep gastritis with the lubricant prepared in step (1) for 20 minutes.

[0040] The breakage rate of sheep casings has been reduced from the initial 15% to less than 2%.

Abstract

The invention discloses a lubricant for natural casings and a preparation method thereof. According to the invention, the lubricant for the natural casings is composed of the following components by mass: 1 to 10% of a surfactant, 0.2 to 4% of animal and vegetable oils, 0.5 to 5% of mineral oil, 8% to 15% of glycerol and 0 to 2% of ingredients, with the balance being water. The method comprises the following steps: removing contents in original intestines and then carrying out watering and soaking, and fully infiltrating the intestines into the lubricant so as to promote infiltration and adsorption; thus, lubrication effects are obtained, and breakage of casing products in processing process is greatly reduced. The lubricant provided by the invention has low cost, is convenient to prepare, improves operability of the intestines, reduces economic loss and can be widely applied in production of the natural casings.

Description

technical field [0001] The invention belongs to the technical field of natural casing processing, and in particular relates to a natural casing lubricant and a preparation method and application thereof. Background technique [0002] From inside to outside, the intestine can be divided into four layers: mucosa, submucosa, muscular layer, and serosa. Natural casings are fresh intestines of domestic animals, which are processed to remove extraintestinal adipose tissue, serosa and mucous membranes, and obtain thin, translucent intestines that retain toughness. When processing casings, separate the parts of the intestine first, remove the intestinal contents, remove the mesentery and extraintestinal fat, and finally scrape off the intestinal mucosa. Since the fat of the intestine is removed, the lubricating effect is reduced, so the original intestine is easily damaged during the operation, especially in the stage of intestinal scraping, if the internal and external lubrication...
