Combined effects of ascorbic acid and chitosan on the quality maintenance and shelf life of plums

Pre-storage Application of Antioxidant Alleviates Chilling Injury and Maintains Quality of Valencia Orange Fruits Stored at Low Temperature

“…An increase in activity of POX enzyme was observed during exposure of intact plants to low temperature (Xu & Tian, 2008;Chongchatuporn et al, 2013 andLiu et al, 2014). In this study, antioxidant treatments were observed higher activity of POX enzyme than untreated fruits.…”

“…The activity of peroxidase (POX) has also been thought to be related to the prevention of chilling damage, as they also use hydrogen peroxide (El-hilali et al, 2003). The increase in resistance of plants that had become acclimatized to low temperature was correlated with increased POX activity (Chongchatuporn et al, 2013 andLiu et al, 2014).…”

Mild heat treatment inhibits the browning of fresh-cut Agaricus bisporus during cold storage

“…The assay of PAL activity was measured according to the procedure described by Liu, Yuan, Chen, Li, and Liu (2014) with some modifications. For enzyme extraction was as follows: frozen mushroom powder (2.0 g) was mixed in 10 mL of 0.05 mmoL/L sodium borate buffer (pH 8.5) containing 0.4 g of polyvinylpyrrolidone and 5 mmoL/L of b-mercaptoethanol at 4 C. The mixture was centrifuged at 10 000Âg for 15 min at 4 C, and then, the supernatant was collected for performing an enzyme assay.…”

Effect of Hydroxypropyl Methylcellulose-Beeswax Composite Edible Coatings Formulated with or without Antifungal Agents on Physicochemical Properties of Plums during Cold Storage

“…Several works in the literature report that edible coatings based on whey protein [21], hydroxypropyl methylcellulose (HPMC) [2,14,22], alginate [23], and chitosan [24][25][26] preserved the postharvest quality of plums by maintaining fruit firmness and reducing weight loss, internal breakdown and respiration, and decay rates of coated plums. The effect of these coatings on weight loss, firmness, and internal breakdown greatly depended on coating composition.…”
