Biocompatible Nanopolymer Coating Based on Chitosan Nanoprecipitation Containing Guava Oil to Control Fruit Rot, Enhance Defense‐Related Enzymes, and Quality of Chili Pepper

Future Postharvest and Food, Volume 2, Issue 3, Page 335-360, September 2025.
ABSTRACT This study evaluates the efficacy of chitosan nanoprecipitation loaded with guava leaf essential oil as a sustainable alternative to synthetic preservatives for reducing postharvest deterioration in Capsicum frutescens (chili pepper). Essential oils extracted from Psidium guajava leaves via hydrodistillation were analyzed by GC‐MS, identifying

Activity and Process Stability of Purified Green Pepper (Capsicum annuum) Pectin Methylesterase

, 2004
Pectin methylesterase (PME) from green bell peppers (Capsicum annuum) was extracted and purified by affinity chromatography on a CNBr-Sepharose-PMEI column. A single protein peak with pectin methylesterase activity was observed.

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

Journal 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

Cold plasma processing of kiwifruit juice: Effect on physicochemical, nutritional, microstructure, rheological properties and sensory attributes

Journal of Food Science, Volume 89, Issue 10, Page 6127-6141, October 2024.
Abstract This study aimed to compare the untreated, cold plasma (CP)‐optimized (30 kV/5 mm/6.7 min), CP‐extreme (30 kV/2 mm/10 min), and thermally treated (TT) (90 ℃/5 min) kiwifruit juices based on the physicochemical (pH, total soluble solids (TSS), titratable acidity (TA), total color change (ΔE)), physical (particle size and rheology ...

Exploring the Effects of Different 1‐MCP Concentration Treatment on Chilling Injury of Postharvest Peach Fruit

Journal of Food Biochemistry, Volume 2024, Issue 1, 2024.
Peach (Prunus persica (L.) Batsch) fruit are susceptible to chilling injury that is often manifested as browning of the internal flesh. As the ethylene antagonist, 1‐methylcyclopropene (1‐MCP) is an important contributor to resist chilling stress during peach (Prunus persica (L.) Batsch) storage at low temperatures, but the molecular mechanism of it is

Texture improvement of fresh and frozen raspberries with pectinmethylesterase and CaCl2 by immersion [PDF]

AIP Conference Proceedings, 2017
The present investigation studied the freezing of raspberries by immersion in CaCl2 solutions and PME and calcium solutions, analyzing textural parameters and microstructure. The combined effects of PME and calcium were confirmed to improve the texture and of both fresh and frozen thawed raspberries.

New NodW- or NifA-Regulated Bradyrhizobium japonicum Genes

Molecular Plant-Microbe Interactions, 2003
A cluster of genes coding for putative plant cell-wall degrading enzymes (i.e., genes for two endoglucanases [gunA and gunA2], one pectinmethylesterase [pme], and one polygalacturonase [pgl]) was identified by sequence similarities in the symbiotic ...
