Effect of Anti Browning Agents on Partial Purified Polyphenol Oxidase of Hawthorn (Crataegus Spp
Objective: Polyphenol oxidase or PPO (EC 1.14.18.1) is considered the enzyme responsible for quality deterioration and browning in different fruits during postharvest period. The objective of this study was to evaluate the antibrowning (inhibition of polyphenol oxidase activity) effect of Cysteine, Ascorbic acid, citric acid, kojic acid and glycine at two different pH (6 and 7) in hawthorn. Me...

متن کاملDirect Electrochemistry of Polyphenol Oxidase
The electrochemistry of banana tissues on a carbon paste electrode modified with multi-walled carbon nanotubes (MWCNTs) is presented. Cyclic voltammetry is applied to investigate the direct electrochemistry of banana tissues i.e. a source of polyphenol oxidase (PPO). A redox couple with an anodic and counterpart cathodic peak is obtained. The influence of various parameters such as pH,...
متن کاملEffects of Rice Bran Extract on Browning and Polyphenol Oxidase Activity in Vegetable and Fruit
The effects of rice bran extract (RBE) on browning in potato, banana and apple slices compared with distilled water (DW) were investigated by measuring the changes of color values. Potato slice treated with RBE had lower browning value than that treated with DW during storage 9 to 12 hrs (p≤0.05). The browning values of potato treated with RBE and DW stored for 12 hrs were 4.72 and 7.64, respec...
متن کاملCharacterisation of Polyphenol Oxidase and Peroxidase and the Role in Browning of Loquat Fruit
Zhang X., Shao X. (2015): Characterisation of polyphenol oxidase and peroxidase and the role in browning of loquat fruit. Czech J. Food Sci., 33: 109–117. Polyphenol oxidase (PPO) and peroxidase (POD) were extracted from a new loquat fruit cultivar (Ninghaibai) and characterised using reliable spectrophotometric methods. In both cases, the optimum pH for PPO was 4.5 and 5 for POD, and their opt...
