Microorganisms in Agriculture and Food industry

420
Microorganisms play a crucial role in agriculture and the food industry, contributing to soil fertility, crop protection, and food production. Their functions range from nitrogen fixation and biopesticide production to fermentation and food preservation, making them indispensable to sustainable farming and food safety.Role in AgricultureNitrogen-fixing bacteria, such as Rhizobium (symbiotic) and Azotobacter (free-living), convert atmospheric nitrogen into ammonia through biological nitrogen...

  • 植物生理学 植物生理学
  • 生物化学 生物化学

背景情况:

  • 新鲜切割的果切片在储存期间迅速降解,呈现棕色和生理损伤.
  • 减少的气 (H2) 含量与这种降解有关.
  • 修改大气的包装 (MAP) 是一种常见的新鲜农产品的保存技术.

研究的目的:

  • 调查气 (H2) 在新鲜切割的果片的保存中的作用.
  • 为了确定在储存期间减轻降解的最佳H2度.
  • 探索H2介导保存的基础分子机制.

主要方法:

  • 新鲜切割的果片在4°C和85%的相对湿度下保存了8天.
  • 气 (H2) 改性大气包装 (MAP) 用不同的H2度 (0.01%,0.1%,1%).
  • 评估了质量属性 (棕色,水分损失,感官质量,营养价值,抗氧化能力).
  • 进行了非向的代谢学和分子分析.

主要成果:

  • 0.1%的H2 MAP处理显著延缓了果片的色和水分损失.
  • 这种度部分恢复了H2平衡,并减缓了感官质量,营养价值和抗氧化能力的下降.
  • 非向的代谢学揭示了通过烯代谢途径对黄类生物合成的上调调节.

结论:

  • 气 (H2) 改性大气 (MAP) 包装显示出保存新鲜切割的果片的巨大潜力.
  • 0.1%的H2度有效地保持了质量属性并延长了保质期.
  • H2 MAP可能通过影响关键代谢途径,为保存和加工新鲜切割的产品提供一种新的方法.
