Problems solved by technology

Although the soaking method is applicable in a wide range, and the aluminum-tanned collagen sausage casings show ideal frying taste and performance when frying sausages, excessive intake of aluminum is harmful to human health, and aluminum has been identified as a food pollutants and restrict the use of
CN201910529320.9 discloses a method for preparing boiled / fried collagen casings, which pretreats cowhide by adding small molecular polyols, strong oxidants and ferric ions. However, this method has potential toxicity and even causes pollution
At present, there are few reports on preparation methods that are not only suitable for the preparation process of wet casings, but also can significantly improve the fried taste and performance of collagen casings. If a simple, safe and economical technology can be provided to solve this problem, it will be of great significance. Satisfy the needs of consumers to a certain extent and improve economic benefits

Embodiment 1

[0041] The oil-fried collagen casing was prepared by wet immersion, as follows:

[0042] (1) Preparation of Bullithm: Bullocate the pretreated cattle 2 layers, cutting 7 min at a high speed pulverizer, and adding threshing ice to control the temperature at 13 ° C;

[0043] (2) Preparation of mixed acids: 0.36 wt% hydrochloric acid solution, add 2.3 wt% cork, hydrochloric acid solution, mix well to obtain an acid mixture;

[0044] (3) Preparation of colon group: mixed with a maternal mixture prepared in (2) with a leather pulp in (1) to prepare collagen group, stored at 8 ° C for 18 h;

[0045] (4) Extrusion curing: After the collagen group is filtered under 30 MPa pressure, the rotation speed is 20 rpm extruded machine extrusion, venting air and ammonia gas, the pressure is 20 psi, the temperature is at room temperature, the temperature is 2 min ;

Abstract

The invention provides a method for preparing deep-fried collagen casings by wet soaking. The method comprises the following steps: mincing cowhide, pickling for the first time, homogenizing, curing, cross-linking, washing, plasticizing, drying and rewetting to obtain the deep-fried collagen casings. The deep-fried collagen casings prepared by the method have the advantages that the taste, the viscosity and the deep-frying characteristic are obviously improved.

Description

Technical field [0001] The present invention relates to the field of collagen casing processing, and more particularly to a method of preparing oil-fried collagen casings in wet immersing. Background technique [0002] Collagen casings have similar properties with natural casings and less cost, so that artificial collagen casings are often produced to compensate for the production of natural casings, and their preparation process is divided into dry and wet. Unlike the first expansion and drying of the dry method, the wet method first cries and extruded the collagen fibers, and then improving, enhanced, enhanced in the solution, so that the collagen prepared by wet method The casing is more soft and delicate than the dry casings. [0003] However, the performance of the moisture collagen casings in practical applications, the performance of the steamed and fried characteristics is still not as good as natural casings. Through the solution of the crosslinking agent such as glutara...
