Bioactive peptides from blackberry (Rubus L.) seed proteins: enzymatic production, fractionation, and multi-functional properties
Blackberry (Rubus L.) seeds are an underutilized processing byproduct containing 20–25% protein, yet their protein fraction has received limited attention. This study aimed to optimize enzymatic hydrolysis of blackberry seed protein isolate (BSPI), fractionate the resulting hydrolysate, and comprehensively evaluate the...
