Summary: The susceptibility of pomegranate fruit to chilling injury of the peel (CIp) during cold storage was found to be associated with downregulation of PHENYLALANINE AMMONIA-LYASE (PAL) and upregulation of POLYPHENOL OXIDASE (PPO). Pre-storage washing with CaCl2 and citric acid was effective in reducing CIp incidence by increasing antioxidation-related gene expression.

Summary: Fruit juices are frequently consumed due to their nutritious benefits, appealing flavor, and vibrant color. The stability of enzymes in fruit juices is a concern for their shelf life. In the past two decades, there has been a transformation in the fruit juice processing industry from thermal treatments to nonthermal treatments (NTTs) to meet the requirements for microbiological and enzymatic stability. NTTs have the potential to produce microbiologically safe and enzymatically stable fruit juices with minimal loss of bioactive components. The inactivation of enzymes in NTTs mainly occurs through protein structure modification and active site conformation.

Summary: The study investigated the thermal effects on the inactivation kinetics of polyphenol oxidase (PPO) and peroxidase (POD) in lily bulb as well as the functional properties of its flours. Blanching treatment at high temperatures was found to reduce browning and increase the swelling power and water solubility index of lily bulb flours. The blanching process also resulted in increased viscosity and changes in the rheological properties of the flours.

Summary: This study investigated the effects of ohmic heating blanching (OHB) at different temperatures (67-90°C) on the inactivation of polyphenol oxidase (PPO), color, and texture in Agaricus bisporus mushrooms. Results showed that OHB was able to inactivate PPO more quickly and with less impact on the color and texture of the mushrooms compared to conventional blanching. The OHB process also had a lower energy activation value.

Summary: A study was conducted to investigate the changes in polyphenol oxidase (PPO) activity, surface color, and hydroxymethylfurfural (HMF) content in fresh and pre-frozen peach slices stored at different temperatures. The results showed that browning and PPO activity were more pronounced in peaches stored at -7°C compared to those stored at -9°C and -12°C. The peach slices treated with blanching, followed by ascorbic acid and citric acid dip, exhibited less discoloration and lower PPO activity. Non-enzymatic browning was more significant in blanched peaches during storage. Pretreating blanched peaches with ascorbic acid and citric acid reduced browning during frozen storage at -9°C or -12°C.

Summary: This study compared the composition and bioactivity of oil extracted from pomegranate seeds using different drying methods from sun-burned fruit and healthy fruit. The results showed that oven dried seeds from sun-burned fruit had the highest oil yield and antioxidant activity, while the oil extracted from seeds of healthy fruit exhibited stronger antimicrobial activity. The fatty acid composition was not affected by fruit quality and seed drying method. Therefore, seeds from sun-burned fruit can be used as a good raw material for cosmetic formulation.

Summary: This study evaluated the potential of a chitosan-based melatonin composite coating to maintain the quality and delay senescence of minimally processed pomegranate aril-sacs during refrigerated storage. The results showed that the coating treatments significantly delayed weight loss and respiration rate, retained desirable properties such as color, ascorbic acid content, anthocyanin content, and antioxidant capacity, and suppressed surface browning development. The recommended treatment concentration for optimal results was 0.8-1 mM melatonin. The findings of this study have important implications for preserving the quality and extending the storage life of minimally processed pomegranate aril-sacs.
