The aim of the present study was to examine the efficiency of chitosan-pullulan composite edible coating enriched with pomegranate peel extract (CP-PPE) on the quality and shelf life of tomatoes over 18 days of storage at 23 °C and 4 °C. The applied composite edible coating significantly (p ≤ 0.05) improved postharvest quality (weight loss, maintained total soluble solids, titratable acidity, color, pH, and retained higher phenolic content, flavonoid content, and antioxidant activity) and sensory characteristics throughout the storage at both room and cold temperatures. On day 15, higher overall acceptability was observed in treated samples (6.27 ± 0.20) as compared to untreated (4.41 ± 0.39) at 23 °C. On day 18, the higher sensory scores were also recorded for treated samples (7.15 ± 0.1) compared to untreated (6.41 ± 0.14) at 4 °C. The shelf life of tomatoes was enhanced by 9 days at 23 °C and at 4 °C conditions; both types of samples were good up to the final day of storage.

富含石榴皮提取物的壳聚糖-普卢兰复合食用涂层改善番茄（Solanum lycopersicum L。）的货架期和品质。
本研究的目的是研究富含石榴皮提取物（CP-PPE）的壳聚糖-普鲁兰复合可食用涂层对番茄在23°C和4°C下储存18天的质量和保质期的效率。复合食用涂料的应用显着（p≤0.05）提高了贮藏后质量（重量减轻，总可溶性固形物保持不变，可滴定的酸度，颜色，pH值并保留了较高的酚含量，类黄酮含量和抗氧化活性）以及整个室温和低温下的贮藏感官特征。在第15天，在23°C下观察到与未经处理的样品（4.41±0.39）相比，经过处理的样品（6.27±0.20）具有更高的总体可接受性。在第18天，与未处理（6.41±0.14）在4°C相比，处理过的样品（7.15±0.1）的感官评分也更高。在23°C和4°C的条件下，西红柿的货架期延长了9天；两种类型的样品在储存的最后一天都很好。
