Metabolic response of vitamin C and phenolic compounds in fresh‐cut pineapple induced by pulsed electric fields

open access: yesFuture Postharvest and Food, Volume 1, Issue 4, Page 454-465, December 2024.
The proposed scheme explains the mechanism of action of the pulsed electric field (PEF – 5 pulses) on the metabolism of vitamin C and phenolic compounds during refrigerated storage (10°C) of minimally processed pineapple. Abstract The loss of nutritional quality is the main factor associated with the perishability of minimally processed foods.

Improving blueberry cold storage quality: the effect of preharvest hexanal application on chilling injuries and antioxidant defense mechanisms

open access: yesJournal of the Science of Food and Agriculture, Volume 104, Issue 14, Page 8837-8851, November 2024.
Abstract Blueberries are vulnerable to chilling injury (CI). This can lead to limited longevity when they are subjected to cold storage conditions. This study investigated the effectiveness of a preharvest spray containing 0.02% hexanal in reducing CI and improving the postharvest storage quality of ‘Star’ and ‘Biloxi’ blueberries. The blueberries were
