Embodiment 1

[0022]The gelatinization process of the acid-based bone gelatin described in this embodiment is to make bovine bones successively through crushing, degreasing, pickling, liming, washing, gel extraction, purification, concentration, sterilization, forming, drying, inspection and The step of packaging is to produce osteoin gelatin; wherein: the crushing and defatting refers to crushing the bovine bone to 6-10mm, and performing thermal degreasing treatment at 75°C, and using hot air at 80-100°C after sieving the bone particles Drying; the pickling refers to immersing the bone grains in a food-grade hydrochloric acid solution for pickling treatment for 24 hours, and the described pickling refers to immersing the bone grains in a food-grade hydrochloric acid solution, the pH of the hydrochloric acid solution The temperature is 1.0-1.2, and the temperature is 15°C; the liming step includes soaking the bone particles obtained after pickling in a lime emulsion with a concentration of 5...

Embodiment 2

[0025] The difference from Example 1 is only that the lime emulsion treated by liming also contains quaternary ammonium hydroxide, and the quaternary ammonium hydroxide is tetramethylammonium hydroxide, and the described lime emulsion contains 0.5wt% of tetramethylammonium hydroxide. The acid-processed bone gelatin prepared by the gel-making process of this embodiment has stable properties, a yield of over 90%, a viscosity of 29-32 mpa.s (60° C.), and a moisture content of 11.0-13.8.

Abstract

The invention relates to a gelatin preparation process for acid process bone element gelatin. The process is characterized in that animal bones are sequentially subjected to steps of crushing, degreasing, acid soaking, ash soaking, water washing, gelatin extraction, purification, concentration, sterilization, forming and drying to obtain the bone element gelatin; the ash soaking step comprises the processes that bone particles obtained after the acid soaking are soaked for 15 to 20 hours in lime emulsion with the concentration being 3 to 8 baume degree, then, the lime emulsion is completely discharged, 35-percent phosphoric acid water solution is added for treatment for 3 to 5 hours, and 5L of phosphoric acid water solution is added for each ton of bone grains. Through the optimized control and innovation on the gelatin preparation process, the material selection and the parameters, the technical problems of poor product performance stability and low yield in the gelatin preparation process for the acid process bone element gelatin are solved, the production period is shortened to 3 to 5 days, the waste water discharge quantity is low, the cost is low, in addition, the yield is as high as more than 90 percent, and good foundation is laid for the industrial scale production.

Description

technical field [0001] The present invention relates to the preparation technology of gelatin, more specifically the present invention relates to a kind of gelatin making process of acid-processed osteoin gelatin. Background technique [0002] Gelatin is a water-soluble protein mixture, generally produced by partial hydrolysis of collagen in animal bones, ligaments, tendons, etc. by acid or alkali, or by boiling in water, and swells in water at 35-40°C to form a gel. The content of protein in gelatin is greater than 82%, about 2% of various minerals, except tryptophan, which contains 18 kinds of amino acids needed by the human body. Gelatin is soluble in hot water and forms a thermally reversible gel with excellent physical properties, such as jelly force, affinity, high dispersibility, low viscosity characteristics, dispersion stability, water holding capacity and reversibility, etc. Gelatin is usually used as a food additive, such as a food jelly agent, stabilizer, thicke...
