Forage Polyphenol Oxidase and Ruminant Livestock Nutrition [PDF]

Frontiers in Plant Science, 2014
Polyphenol oxidase (PPO) is associated with the detrimental effect of browning fruit and vegetables, however interest within PPO containing forage crops has grown since the brownng reaction was associated with reduced nitrogen (N) losses in silo and the

Olive Polyphenol Oxidase Gene Family. [PDF]

Int J Mol Sci, 2023
The phenolic compounds containing hydroxytyrosol are the minor components of virgin olive oil (VOO) with the greatest impact on its functional properties and health benefits. Olive breeding for improving the phenolic composition of VOO is strongly dependent on the identification of the key genes determining the biosynthesis of these compounds in the ...

An In Vitro Catalysis of Tea Polyphenols by Polyphenol Oxidase. [PDF]

Molecules, 2023
Tea polyphenol (TPs) oxidation caused by polyphenol oxidase (PPO) in manufacturing is responsible for the sensory characteristics and health function of fermented tea, therefore, this subject is rich in scientific and commercial interests. In this work, an in vitro catalysis of TPs in liquid nitrogen grinding of sun-dried green tea leaves by PPO was ...

Polyphenol oxidases exhibit promiscuous proteolytic activity [PDF]

Communications Chemistry, 2020
AbstractTyrosinases catalyse both the cresolase and catecholase reactions for the formation of reactive compounds which are very important for industrial applications. In this study, we describe a proteolytic activity of tyrosinases. Two different tyrosinases originating from mushroom and apple are able to cleave the carboxylesterase EstA. The cleavage

Effect of antioxidants and pH on browning and firmness of minimally processed eggplant

Notulae Botanicae Horti Agrobotanici Cluj-Napoca, 2020
Minimal processing of eggplant (Solanum melongena L.) generates loss of firmness and polyphenol oxidase catalyzes the oxidation of phenolic compounds producing enzymatic browning. The aim of this study was to evaluate the effect of 1% ascorbic acid and 2%

Characterization of Polyphenol Oxidase from Eruca sativa

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2023
Enzymatic browning reactions by polyphenol oxidases cause alteration of appearance, flavor and nutritive value of vegetables and fruits. It is one of the important problems for vegetables used as salads and causes lots of economic losses. In this study,

Obstruction of Water Uptake in cut Chrysanthemum Stems after Dry Storage: Role of Wound-induced Increase in Enzyme Activities and Air Emboli [PDF]

, 2009
Hydraulic conductance of cut chrysanthemum stems was lowered by the aspiration of air as well as by a wound-induced plant response. By measuring the hydraulic conductance of stem segments in which air could be introduced into and/or removed from the ...
