Abstract

ABSTRACT A novel edible coating with marine yeast in chitosan matrix was prepared. The biocompatibility of yeast cell incorporation of developed coatings was evaluated in terms of viability. Furthermore, the application of chitosan-based coatings was investigated in order to evaluate their efficacy to preserve postharvest quality and prevent fungal establishment of Penicillium italicum during storage under refrigeration. Results revealed that commercial chitosan as a matrix is compatible with Debaryomyces hansenii by maintaining 100% viability of the initial inoculum using chitosan at 0.5%. Preventive application of chitosan combined with the antagonistic yeast was more effective for controlling fungus infection than individual treatments of chitosan and yeast, showing an additive effect. Chitosan concentration had an impact on pH, TSS, acidity, and colour values. Further, the addition of yeast improved the barrier properties of coatings. This study demonstrates the potential application of chitosan-based coatings with antagonistic yeast D. hansenii for Persian lime quality maintenance as well as an effective alternative against blue mould disease.

生物活性壳聚糖基涂层与海洋拮抗剂防治意大利青霉引起的波斯石灰采后腐烂的应用

摘要:制备了一种新型的壳聚糖海洋酵母可食用涂层。从生物活性的角度评价了该涂层与酵母细胞结合的生物相容性。此外，还研究了壳聚糖基涂层在保鲜保鲜和防止意大利青霉在冷藏过程中产生真菌的效果。结果表明，以0.5%的壳聚糖作为基质，初始接种量可保持100%的生存力，与汉斯德巴氏菌相容。壳聚糖与拮抗酵母菌联合预防性应用对真菌感染的防治效果优于壳聚糖与酵母菌单独应用，具有加性作用。壳聚糖浓度对pH、TSS、酸度和颜色值有影响。此外，酵母的加入改善了涂层的阻隔性能。本研究证明了壳聚糖基抗生酵母涂层在波斯石灰质量维护中的潜在应用，以及蓝霉病的有效替代。
