bromelain/potato

The inhibitory specificity of a protein from potato tubers that inhibits cysteine proteinases (potato cysteine proteinase inhibitor, PCPI) has been compared with that of chicken egg-white cystatin. Most proteinases that are inhibited by cystatin were also inhibited by PCPI, but the potato inhibitor

Three protein inhibitors of proteolytic enzymes with molecular weights 21, 22, and 23 kD were isolated from potato tubers (Solanum tuberosum L.) by ammonium sulfate precipitation followed by gel and ion-exchange chromatography. The 21- and 22-kD proteins were shown to be serine proteinase inhibitors

This study investigated the physicochemical characteristics of potato protein isolate hydrolysate (PPIH) and its antioxidant activity. Potato protein isolate (PPI) was hydrolyzed into PPIH by the proteases bromelain, Neutrase, and Flavourzyme. Compared with PPI, the resulting PPIH had a lower

The aim of this study is to analyze the efficacy of natural bleaching agents and the current technological development in this research field. Two reviewers performed a literature search up to July 2019 in 15 databases. Five laboratory studies and 25 patents were included. Data regarding natural

The papain inhibitor isolated from chicken egg white inhibits the enzymatic activity of cathepsin B1 and cathepsin C. The inhibitor bears two nonoverlapping reactive sites: one binds cathepsin B1, papain, ficin, and bromelain, the other one cathepsin C. The inhibitor decreases the degree of an
