General description

丙二醇是一种脂肪族二元醇,在食品工业中应用广泛,可用作抗结剂,抗氧化剂,保湿剂,风味剂,乳化剂,稳定剂,增稠剂等。

Application


  • 丙二醇对埃及伊蚊葡萄糖消化的致命损害(双翅目:库蚊)和与萜类化合物共同配制,以增强有毒糖饵的吸引力。:本研究探讨了丙二醇在破坏蚊子葡萄糖消化中的应用,为通过增强毒性糖饵控制病媒提供了一种新的方法。与萜类化合物的协同作用扩大了其影响力,标志着病虫害管理战略取得重大进展(Maes et al., 2024)。

  • 嗅觉训练对6 ~ 9岁儿童视觉、听觉或嗅觉工作记忆的无交叉模态影响。:本神经科学研究利用丙二醇在嗅觉训练练习,调查其影响跨模态感觉处理的潜力。尽管研究还没有结果,但它提供了对感觉统合疗法的重要评估(Pieniak et al., 2024)。

  • 青少年慢性摄入玉米淀粉继发的丙二醇毒性。:本医学案例研究解决了过量摄入丙二醇的相关风险,强调了其潜在的毒性作用。这项研究提醒人们,需要对食品中的化学添加剂进行监管审查并提高公众意识(Downey et al., 2024)。
