Production method of gelatin

Abstract

The invention discloses a production method of gelatin and particularly discloses a production method of gelatin suitable for novel capsules and food additives. The method comprises the technological processes of acid pickling, removing acid and washing, neutralizing, washing, enzymolysis and gelatin extraction, refining treatment, concentration, evaporation, sterilization, and extruding and drying. According to the technique, liming treatment is not carried out any more, so that the production period is shortened to 3-7 days, the time is short and the fund occupancy rate is low. Meanwhile, a liming pool does not need to be constructed, so that land and investment are saved. In addition, according to the enzymolysis technology, water consumed for producing one ton of gelatin is only 50-60 tons, and the method is free of solid waste and small in discharge amount of waste residues and wastewater. The treatment time is relatively short and the factors affected by the environment are relatively few, so that the stability of the quality of a product can be ensured, the gelatin is prepared only through one-time enzymolysis under the condition of 45-55 DEG C during gelatin extraction, and the method has the advantages of low energy consumption and high quality gelatin rate.

Description

technical field [0001] The invention relates to a gelatin production process, in particular to a production method of gelatin used for novel capsules and food additives. Background technique [0002] At present, domestic bone gelatin production enterprises are still using the traditional alkaline process to make gelatin. The process includes: pickling→acidification and water washing→liming→ash removal and water washing→neutralization→water washing→heating and gel extraction→refining treatment→concentration→evaporation→extinguishing Bacteria→squeeze glue, dry, such as figure 1 As shown, the production cycle of this process method needs 50-90 days, which takes a long time and has a large capital occupation rate. The liming process needs to build a large number of liming tanks, which occupies a large area and requires a large investment. In addition, every ton produced by this process method Gelatin, 600-1000 tons of water consumption, 10-20 tons of solid waste, large waste re...
