Minimally processed products are highly convenient, and fresh-cut fruits coated with the synbiotic film have many advantages. This study investigated the film-forming components and preservation ability of Da Xanh pomelo and Thai jackfruit fresh-cut by synbiotic pectin film. The results showed that PA70 film combined with 1.5% FOS (fructooligosaccharides) had the highest number of viable cells of after 30 days of storage at 5 °C. The number of probiotic cells existing on fresh-cut products of Da Xanh pomelo and Thai jackfruit was always high (> 8 log CFU/g) and stable during 10 days of storage. In addition, jackfruit and pomelo fresh-cut preserved with probiotic film also showed probiotic activity in simulated stomach and small intestine medium with the number of probiotic cells (> 6 log CFU/g) and survival cell ratio after 4 h in small intestine medium reached 81.20 ± 0.92% (pomelo) and 82.16 ± 0.94% (Thai jackfruit).
最少加工的产品非常方便，而涂有合生元膜的鲜切水果有很多优点。本研究调查了合生元果胶膜对大青柚和泰国菠萝蜜鲜切后的成膜成分和保鲜能力。结果表明，PA70膜与1.5%的低聚果糖（FOS）结合，在5℃储存30天后活细胞数量最多。大青柚和泰国菠萝蜜鲜切产品上存在的益生菌细胞数量在储存10天期间始终很高（>8 log CFU/g）且稳定。此外，用益生菌膜保存的菠萝蜜和柚子鲜切产品在模拟胃和小肠培养基中也显示出益生菌活性，益生菌细胞数量（>6 log CFU/g），在小肠培养基中4小时后的存活细胞比例达到81.20±0.92%（柚子）和82.16±0.94%（泰国菠萝蜜）。
