Abstract

Belonging to the field of gelatin preparation, the invention relates to a method for preparation of gelatin by a composite bioorganic acid and a composite bio-enzyme. The method includes: 1) putting the composite bioorganic acid composed of pyroligneous liquor, citric acid and hydrogen peroxide and the composite bio-enzyme composed of protease, lipase and catalase into a reaction tank for reaction, and performing stirring at intervals; 2) washing the product at the end of the reaction in step 1), then transferring the product into a neutralization tank containing a neutralizer so as to adjustthe pH value of the product; and 3) when the pH of the product regulated in step 2) reaches the standard, transferring the product into a glue pot for multi-pass boiling so as to obtain gelatin gel liquid, and then carrying out filtering, evaporation, skin cutting, refrigeration and crushing, thus obtaining the product. The method provided by the invention utilizes natural bioorganic acids and bio-enzymes to prepare gelatin, and can greatly reduce the production cost, shorten the production cycle and improve the production efficiency.

Description

technical field [0001] The invention belongs to the field of gelatin preparation, and in particular relates to a method for efficiently producing gelatin by using compound biological organic acids and compound biological enzymes. Background technique [0002] Gelatin is partially degraded from collagen in connective tissues such as animal skin, bone, sarcolemma, and muscle. It is white or yellowish, translucent, slightly shiny flakes or powder, so it is called animal gelatin, fat glue, Industrial gelatin is colorless to yellow, transparent or translucent, and tasteless. It absorbs water and expands in cold water. Soluble in glycerin and acetic acid, not in ethanol and ether. [0003] Gelatin is a kind of macromolecular hydrocolloid. It is a low-calorie health food with high nutritional value. It can be used to make candy additives, frozen food additives, etc. In addition, gelatin is also widely used in the pharmaceutical and chemical industries. At present, my country's ...
