This research developed a biodegradable absorbent pad using polybutylene adipate terephthalate (PBAT) and thermoplastic starch (TPS) films, combined with hairy basil () seed powder (HBP) to extend the shelf life of fresh pork during cold storage. To form the biocomposite film, PBAT was blended with TPS in ratios of 100:0, 90:10, 70:30, and 50:50. The PBAT:TPS ratio of 70:30 (PB7T3) was the most suitable in terms of mechanical properties and water permeation. Therefore, PB7T3 was selected to fabricate the absorbent pad for extending the shelf life of fresh pork during cold storage. For the storage test, 100 g of pork pieces was placed in PET trays (12 cm × 12 cm), each containing a different absorbent: the control (no pad), a commercial absorbent pad, and the PB7T3 absorbent pad. The pork samples were stored at 4 °C for 8 days and analyzed for color change, total plate count (TPC), total volatile basic nitrogen (TVB-N), pH, and drip loss on days 0, 2, 4, 6, and 8. The results indicated that the PB7T3 absorbent pad effectively extended the shelf life of fresh pork compared to the control, with no significant difference compared to the commercial absorbent pad made from plastic. This research opens new avenues for developing sustainable absorbent pads, contributing to reduced reliance on conventional non-biodegradable plastics.
本研究开发了一种可生物降解的吸水垫，该吸水垫使用聚己二酸丁二醇酯对苯二甲酸酯（PBAT）和热塑性淀粉（TPS）薄膜，并与毛罗勒（）种子粉（HBP）相结合，以延长鲜猪肉在冷藏期间的保质期。为了形成生物复合薄膜，将PBAT与TPS按100:0、90:10、70:30和50:50的比例混合。就机械性能和透水性而言，PBAT:TPS比例为70:30（PB7T3）是最合适的。因此，选择PB7T3来制造吸水垫，以延长鲜猪肉在冷藏期间的保质期。在储存试验中，将100克猪肉块放入PET托盘（12厘米×12厘米）中，每个托盘含有不同的吸水材料：对照组（无吸水垫）、商用吸水垫和PB7T3吸水垫。猪肉样品在4℃下储存8天，并在第0、2、4、6和8天分析其颜色变化、总平板计数（TPC）、总挥发性盐基氮（TVB-N）、pH值和滴水损失。结果表明，与对照组相比，PB7T3吸水垫有效地延长了鲜猪肉的保质期，与由塑料制成的商用吸水垫相比无显著差异。本研究为开发可持续吸水垫开辟了新途径，有助于减少对传统不可生物降解塑料的依赖。
