Researchers at Department of Biotechnology Discuss Findings in Applied Bioinformatics (Extraction and quantitation of coumarin from cinnamon and its effect on enzymatic browning in fresh apple juice: a bioinformatics approach to illuminate its ...)
By a News Reporter-Staff News Editor at Life Science Weekly -- Investigators publish new report on Applied Bioinformatics. According to news reporting out of Tamil Nadu, India, by NewsRx editors, research stated, "Enzymatic browning by polyphenoloxidase (PPO) affects food quality and taste in fruits and vegetables. Thus, the study was designed to reduce browning in apple juice by coumarin."
Our news journalists obtained a quote from the research from the Department of Biotechnology, "The ethanolic extract of cinnamon was prepared and its coumarin content was quantitated by HPLC, using authentic coumarin (AC) as standard. The effect of cinnamon extract (CE) and AC on enzymatic browning, its time dependent effects, and the specific activity of PPO and peroxidase (POD) were studied in apple juice. The docking of coumarin with PPO and POD was also performed to elucidate its antibrowning mechanism. The CE (73%) and AC (82%) showed better reduction in browning, maintained its antibrowning effect at all time points, and significantly (p
According to the news editors, the research concluded: "Coumarin showed strong interaction with binding pockets of PPO and POD, suggesting its potential use as inhibitor to enzyme mediated browning in apple juice."
