Abstract:

A fresh-keeping film for eggs was prepared with soluble soybean polysaccharides (SSPS), glycerin and anhydrous CaCl2. The film permeability rate (Pv) for water was emphatically investigated. Results revealed that the film exhibited the lowest permeability rate for water when the concentrations of SSPS, glycerin and anhydrous CaCl2 were 6.0%, 3.0% and 1.5%, respectively. The eggs coated with this film still exhibited excellent quality as an A level during storage for 30 days at room temperature. Therefore, SSPS film can provide an excellent fresh-keeping effect on eggs during storage.

Key words: soluble soybean polysaccharides, permeability rate, egg, fresh-keeping film
