In this study, an edible biocomposite coating of alginate extracted from the brown seaweed Dictyota mertensii was loaded with beeswax nanoparticles (BDMAB) to extend the shelf life of yellow passion fruit (Passiflora edulis f. flavicarpa). The films were characterized by morphology, moisture content, contact angle, water vapor permeability, solubility, and optical and mechanical properties. Using a 4 × 6 factorial design, coated fruit was evaluated during six storage intervals (0, 2, 4, 6, 8, 10 days) at 22.5 ± 0.5 °C and 65 ± 5 % RH, focusing on respiration rate, weight loss, peel thickness and color, pulp yield and color, soluble solids, titratable acidity, ascorbic acid, phenolics, antioxidant capacity, and sensory acceptance. The BDMAB coating, composed of 67.9 % (w/w) ADM (bleached), 5 % (w/w) glycerol, 8.5 % (w/w) beeswax, and 18.6 % (w/w) Tween 80, significantly (p < 0.05) reduced the respiration rate, minimized weight loss, and preserved quality attributes, such as acidity, ascorbic acid, phenols, and antioxidant capacity. A 3-day extension in shelf life was inferred based on the climacteric peak delay of BDMAB-coated fruits compared with the control. Sensory analysis confirmed the acceptance of BDMAB coating. Therefore, BDMAB biocomposite coatings have great potential for preserving yellow passion fruit and promoting sustainability and conservation.
在本研究中，将从褐藻网地藻中提取的藻酸盐可食用生物复合涂层负载蜂蜡纳米颗粒（BDMAB），以延长黄百香果（西番莲黄果变种）的货架期。通过形态、水分含量、接触角、水蒸气透过率、溶解度以及光学和机械性能对薄膜进行了表征。采用4×6析因设计，在22.5±0.5°C和65±5%相对湿度条件下，对涂覆果实进行了六个储存期（0、2、4、6、8、10天）的评估，重点关注呼吸速率、失重、果皮厚度和颜色、果肉产量和颜色、可溶性固形物、可滴定酸度、抗坏血酸、酚类、抗氧化能力和感官接受度。由67.9%（w/w）ADM（漂白）、5%（w/w）甘油、8.5%（w/w）蜂蜡和18.6%（w/w）吐温80组成的BDMAB涂层显著（p<0.05）降低了呼吸速率，使失重最小化，并保留了酸度、抗坏血酸、酚类和抗氧化能力等品质属性。与对照相比，基于BDMAB涂覆果实的呼吸跃变峰延迟，推断货架期延长了3天。感官分析证实了对BDMAB涂层的接受度。因此，BDMAB生物复合涂层在保存黄百香果以及促进可持续性和保护方面具有巨大潜力。
