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
The invention belongs to the technical field of natural casing processing, and particularly relates to a natural casing lubricant and a preparation method and application thereof.
Background
The intestine is divided into mucosa, submucosa, muscularis and serosa 4 layers from inside to outside. The natural casing is a thin tough and semitransparent sausage prepared from fresh intestine of livestock by processing to remove extra-intestinal adipose tissue, serosa and mucosa. When processing sausage casing, the parts of the sausage tube are separated, the mesentery and the extra-intestinal fat are removed after the intestinal content is removed, and finally the intestinal mucosa is scraped. Because the fat of the intestines is removed and the lubricating effect is reduced, the damage of the primitive intestines is easily caused in the operation process, and particularly, the intestinal wall is easily scratched if the internal and external lubrication degree of the primitive intestines is not good in the intestine scraping stage. The proper force of a scraper or the proper adjustment of the distance between two shafts of a membrane removing machine during the intestine scraping is ensured, so as to prevent the intestinal wall from scraping or tearing the outside of the intestine; more importantly, the original sausage is lubricated, and particularly, when the salt casings of pigs and sheep are processed, only submucosa is kept, so that the salt casings are very thin, the lubricating treatment is needed, and the convenience of subsequent operation is improved.
US4062981 and US3451827 disclose a method and corresponding apparatus for casing lubrication, but mainly aim at artificial casings, such as collagen casings, and require special folding equipment, which requires large investment. However, no relevant report and patent is found for the lubrication treatment of natural casings. Therefore, the sausage casing lubricant with good compatibility with the original sausage is developed, and the sausage casing lubricant is vital to reducing the damage of the sausage in the process of scraping the sausage, facilitating the measurement and inspection operation, improving the convenience of the later sausage filling process and improving the production efficiency in the whole processing process of the natural sausage casing.

Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to make the above objects, features and advantages of the invention more comprehensible.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.
Different from the traditional solvent-based lubricant, the novel O/W emulsion-type lubricant is used in the patent, and before intestine scraping, an emulsifier in the emulsion plays a role in lubrication; when the intestines are scraped, the emulsifier and the grease released inside play a role in lubrication; after scraping the intestine, the remaining released fat acts as a lubricant ensuring lubrication throughout the preparation of the casing. For lubricants, viscosity is of great importance, and the spreading rate and quality of the lubricant on the surface of the sausage casing are directly influenced. During the preparation of the emulsion, the types of the emulsifier, the types of the oil phase and the proportion of the emulsifier play a significant role in the viscosity of the emulsion and influence the formation and the stability of the emulsion.
Experiments show that different emulsifiers have limited capability of independently reducing the interfacial tension of an oil-water interface, and two or more emulsifiers are usually compounded for obtaining stable emulsion, so that the prepared emulsion has different viscosities; in addition, the oil phase property has great influence on the emulsion of the emulsifier, and the selection of proper oil is important for preparing the emulsion with proper viscosity. Meanwhile, the viscosity of the oil phase also influences the lubricating effect during or after the intestine is scraped, the viscosity is too low, the fluidity is large, the adhesion is not facilitated, the viscosity of the oil phase is too high, the dispersion is not facilitated, and the good lubricating effect cannot be achieved; further, the compounding ratio of the emulsifiers and the compounding ratio of the grease influence the viscosity of the emulsifiers, the oil phase and the prepared emulsion. Therefore, when the emulsifier type lubricant is prepared, the selection of the type of the proper emulsifier, the type of the oil phase and the proportion are not required to be considered, so that the preparation of the lubricant with proper viscosity is crucial, the problems that the viscosity is too high, the spreading cannot be well caused and a good lubricating effect cannot be achieved are avoided; the viscosity is too small, the adhesion is not easy, the operation is inconvenient, and the good lubricating effect can not be achieved.
