Method for producing oyster tablet by adding oyster shell superfine powder

Abstract

The present invention belongs to the field of deep aquatic product processing technology. The oyster producing process includes separating oyster shell and meat, washing the shell with detergent and soaking in hydrochloric acid solution to eliminate organic impurity, water washing, drying, and crushing into average size below 8 micron; washing the meat first with clear water and then with salt water, rinsing, milling in colloid mill into slurry of average size below 25 micron; mixing the shell powder and meat slurry in the weight ratio of 1 to 4-6; vacuum concentrating the mixture, adding starch as stuffing, wet pelletizing, tabletting and coating with sugar coat to obtain the product. The oyster tablet product has the nutritious components of oyster meat and easy-to-absorb active calcium component.

Description

technical field [0001] The invention discloses a method for producing oyster tablet by adding superfine powder of oyster shell, which belongs to the technical field of deep processing of aquatic products and relates to functional food processing. Background technique [0002] Oyster is a kind of shellfish, more than 70% of its body weight is shell, and more than 90% of the shell is calcium carbonate, which is a good source of calcium. In order to make full use of the calcium content in oyster shells, Weng Zhenhui et al. (1992) prepared food fortified calcium agent - calcium citrate from shells; Hong Pengzhi et al. (2000) prepared active calcium from oyster shells; Ionized calcium is produced from the shell; the patent CN1046442A uses processes such as roasting, ball milling, and screening to extract active ionized calcium containing CaO80%-90%. However, their common disadvantage is that the oyster shells have undergone a complicated extraction process to obtain the product....

AI Technical Summary

Problems solved by technology

However, their common disadvantage is that the oyster shells have undergone a complicated extraction process to obtain the product. When the process is increased, the original active ingredients in the oyster shells will inevitably be lost, and the general pulverization process is used, which is not conducive to Calcium is fully absorbed

The disadvantage is that the raw materials will inevitably lose nutrients such as amino acids (such as taurine) through a series of processes such as heating and filtering. Moreover, although the finished product can reduce the degree of fishy smell, it cannot completely remove the fishy smell. There may also be a characteristic odor that is not pleasant to the senses
