A novel process to separate the eggshell membranes and eggshells via flash evaporation

Eggshell membrane is a kind of cheap, abundant resources with great potential utilization value. A variety active ingredients in it can be used as raw materials for medicine, light industry and other industries. At present, soluble protein, collagen, keratin, sialic acid, hyaluronic acid antimicrobial protein have been successfully extracted from eggshell exploited various fields. This study aimed to separate the fully exploiting value eggshell, reduce amount waste discharged, which conducive protecting ecological environment on we depend. In order energy consumption separation, membranes eggshells by flash evaporation was investigated. The separation conditions were optimized considering three independent variables at different levels response surface methodology. results showed that processing parameters separating 1.0 Mpa pressure, 45% moisture content, 5 mm eggshells’ particle size. Under these conditions, rate 69.16%. Therefore, promising approach membranes.
