概括
这项研究开发了活性生物降解包装 (PLA-PHB-CARV),通过减少腐烂和抑制成熟,显著延长桃番茄的保质期. 这种创新的包装为传统塑料提供了可持续的替代品,最大限度地减少了食品浪费.
科学领域:
- 食品科学与技术 食品科学与技术
- 材料科学 材料科学 材料科学
- 生物技术是生物技术.
背景情况:
- 传统的食品包装通常依赖于石化基塑料,导致环境问题.
- 延长桃番茄等新鲜农产品的保质期对于减少食物浪费和改善食品获取能力至关重要.
- 活性改性大气 (EMAP) 包装提供了一种有前途的方法,通过结合功能组件来提高食品的保存性.
研究的目的:
- 开发和评估一种活性可生物降解的生物基平衡改性大气 (EMAP) 包装,其中包含一种卡瓦克罗尔排放袋.
- 评估这种新型包装 (PLA-PHB-CARV) 在延长桃番茄在不同温度 (15°C和25°C) 的保质期方面的有效性.
- 为了比较开发的包装与传统聚烯 (PP) 和非活性聚乳酸 (PLA) 包装的性能.
主要方法:
- 开发一种以聚乳酸 (PLA) 为基础的EMAP,配有释放卡瓦克罗的聚酸 (PHB) 囊.
- 桃番茄在PLA-PHB-CARV,PP和PLA包装中在15°C和25°C保存20天.
- 综合分析质量参数,包括减肥,衰变,微生物计数 (TVC),pH,可定位酸度 (TA),总溶性固体 (TSS),颜色,纹理和感觉属性.
主要成果:
- 与PP和PLA相比,PLA-PHB-CARV包装显著降低了腐蚀 (40%与25°C的PP相比97%),减轻了体重.
- 在25°C的PLA-PHB-CARV中,成熟显著延迟,这可以通过抑制TSS积累和保留红色来证明.
- 活性包装中的卡尔瓦克罗尔在25°C时抑制了总活力计数 (TVC) 约2.0 log CFU/g,在15°C时影响较小.
结论:
- 开发的活性生物降解EMAP (PLA-PHB-CARV) 通过减少腐烂和延迟成熟,有效地延长桃番茄的保质期.
- 这种先进的包装系统是传统塑料的可持续替代品,为减少食物浪费提供了巨大的潜力.
- 这些发现表明,这种活性EMAP在保存具有类似呼吸速率的其他水果方面具有广泛的适用性.

Biopesticides offer a sustainable alternative to chemical pesticides, utilizing microbial agents to control agricultural pests. Bacillus thuringiensis (Bt) is a widely employed bacterium known for its potent insecticidal activity. Bt biopesticides are favored for their specificity to insect pests, minimal environmental impact, and natural degradability.Mechanism of Bt Toxin Action Bt produces insecticidal crystal (Cry) proteins during its sporulation phase. These proteins form parasporal...

Bioplastics

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...
