摘要

由于真菌感染导致柑橘采后质量下降,因此需要创新的包装解决方案。本研究提出了一种含有生物防治酵母菌的拉鲁兰基可食用薄膜(PBYFs),其设计可溶于液体和土壤中。这种薄膜能够包裹整个柑橘类水果,有效控制采后病害并延长其货架期。PBYF 的配方包括 0.1 M 的 NaCl、1.0 × 107 CFU mL-1 的 Kloeckera apiculata 34-9、3 % w/v的 pullulan、0.5 % w/v 的 SA 和 1 % w/v 的甘油。我们在八个柑橘品种上进行的实验表明,PBYFs 能显著减少绿霉、蓝霉、酸腐病和炭疽病的发生。此外,涂有 PBYFs 的水果还能延长保质期,而不会影响重量损失、TSS(总可溶性固形物)、TA(可滴定酸度)、VC(维生素 C)或异味挥发物积累等质量指标。这项研究为创建可扩展、经济高效、环境可持续的柑橘类水果生物降解抗真菌包装系统提供了一种前景广阔的方法。

Pullulan-based coatings carrying biocontrol yeast mixed with NaCl to control citrus postharvest disease decays

The decline in postharvest citrus quality due to fungal infections necessitates innovative packaging solutions. This study presents a pullulan-based edible film (PBYFs) with biocontrol yeasts, designed to dissolve in both liquid and soil. This film is capable of enveloping entire citrus fruits, effectively managing postharvest diseases, and extending their shelf life. The formulation of PBYFs includes NaCl 0.1 M, Kloeckera apiculata 34–9 at 1.0 × 107 CFU mL−1, pullulan 3 % w/v, SA 0.5 % w/v, and glycerin 1 % w/v. Our experiments, conducted on eight citrus varieties, demonstrated that PBYFs significantly reduced the occurrence of green and blue molds, sour rot, and anthracnose in vivo. Moreover, PBYFs-coated fruits exhibited an extended shelf life without compromising the quality parameters such as weight loss, TSS (total soluble solids), TA (titratable acidity), VC (vitamin C), or the accumulation of off-flavor volatiles. This research presents a promising approach for creating scalable, cost-effective, and environmentally sustainable biodegradable antifungal packaging systems for citrus fruits.

期刊介绍: Pesticide Biochemistry and Physiology publishes original scientific articles pertaining to the mode of action of plant protection agents such as insecticides, fungicides, herbicides, and similar compounds, including nonlethal pest control agents, biosynthesis of pheromones, hormones, and plant resistance agents. Manuscripts may include a biochemical, physiological, or molecular study for an understanding of comparative toxicology or selective toxicity of both target and nontarget organisms. Particular interest will be given to studies on the molecular biology of pest control, toxicology, and pesticide resistance. Research Areas Emphasized Include the Biochemistry and Physiology of: • Comparative toxicity • Mode of action • Pathophysiology • Plant growth regulators • Resistance • Other effects of pesticides on both parasites and hosts.
