This study was aimed to characterize and identify a fraction from silver carp muscle hydrolysates (SCMHs) with cryoprotective effects on yeast. The SCMHs were obtained from the hydrolysis of silver carp (Hypophthalmichthys molitrix) muscle with Protamex at 50 °C for 15–240 min. The addition of SCMH generated from 30 min of proteolysis (SCMH-30) led to an increase in the yeast survival rate from 0 – 1% (control) to 82–91% after 1–2 freeze-thaw cycles. The SCMH-30 was further separated into two fractions using gel filtration chromatography. ...
