Enzymatic polyphenoloxidase inactivation with temperature and ozone in sugarcane variety RB 92579 to produce lower color sugar

Brazilian Journal of Food Technology, 2019
Some sugarcane varieties have high activity of polyphenoloxidase enzyme, impairing the production of lower color sugar. Polyphenoloxidase (PPO) is an enzyme from the oxidoreductases group and it is present in a greater or lesser amount depending on the ...

Polyphenoloxidase activity in peaches after vibration [PDF]

Engenharia Agrícola, 2013
The vibration during transportation is one of the main causes of fruit damage. The actual methodologies used for damage evaluation in fruits seem to be subjective, since most of them are based on visual evaluation. In this study the effect of vibration, for one and two hours, on polyphenoloxidase (PPO) activity in peach pulp was investigated.

Enzymatic and Nonenzymatic Antioxidant Systems Affected by the Application of Hydrothermal Treatment and Calcium Chloride in Papaya Fruit

International Journal of Food Science, Volume 2026, Issue 1, 2026.
Papaya fruits have a high content of bioactive compounds that provide them high antioxidant capacity; however, these fruits undergo rapid deterioration processes once harvested, which implies a decrease in antioxidant activity. In order to reduce the oxidative stress that causes deterioration in the fruit, it is important to use technologies to ...

Progress in the study of dioecy in Mexican cycad species and its implications for conservation

Plant Species Biology, Volume 40, Issue 6, Page 556-571, November 2025.
Cycads are endangered dioecious plants of great ornamental value that have a long period of sexual maturity. Therefore, it is crucial to have methods for early sex determination that can help to develop effective strategies for their conservation. Abstract Dioecy is a system of sexual reproduction in plants, characterized by the spatial separation of ...
