Variation of Total Polyphenol and Polyphenol Oxidase Activity during Maturation of Mango Fruit (Mangifera indica L. ‘Irwin’) Cultured in a Plastic House
‘Irwin’ mango fruit maturation of mango variation of total polyphenol
2009/7/8
Variation of total polyphenol (TPP) and polyphenol oxidase activity (PPO) was investigated in ‘Irwin’ mango fruit in various color stages of development: green, purple, purplish red and red. Fruits us...
Effects of Polyphenol Oxidase Activity in Wheat Flour on Protein-Bound 5-S-Cysteinyldopa Formation in Gluten
5-S-cysteinyl-3 4-dihydroxyphenylalanine (5-S-cysteinyldopa) polyphenol oxidase
2009/7/8
The effects of polyphenol oxidase (PPO) activity in wheat flour on the formation of protein-bound 5-S-cysteinyl-3, 4-di-hydroxyphenylalanine (5-S-cysteinyldopa) in gluten have been studied. The wheat ...
Effects of Sucrose Palmitic Acid Ester Coating on the 1-Aminocyclopropane-1-Carboxylate (ACC) Oxidase Activity in the Peel and Pulp of Ripening Banana Treated with Ethylene
Banana ripening sucrose palmitic acid ester
2009/7/7
Bananas were coated with 2% sucrose palmitic acid ester after treatment with 100 ppm ethylene for 12 h and stored at 20°C. The use of 2% sucrose palmitic acid ester coating significantly reduced weigh...
Banana Polyphenol Oxidase: Occurrence and Change of Polyphenol Oxidase Activity in Some Banana Cultivars during Fruit Development
polyphenol oxidase tyrosynase development period
2009/5/31
Occurrence of polyphenol oxidase (PPO, o-diphenol: oxygen oxidoreductase, EC.1.10.3.1) in the fruits of nine cultivars of banana (Musa spp.) commercially cultivated in China was investigated. All bana...
