The sol-gel approach to encapsulate fragrance and aroma chemicals in porous silica-based materials has the potential to afford odorant and flavoured materials with novel and unique beneficial properties. Amorphous sol-gel SiO2 is non-toxic and safe, whereas the sol-gel entrapment of delicate chemicals in its inner pores results in pronounced chemical and physical stabilization of the entrapped actives, thereby broadening the practical utilization of chemically unstable essential oils. Reviewing progress in the fabrication of diverse odorant and flavoured sol-gels, we show how different synthetic strategies afford advanced materials suitable for practical application with important health and environmental benefits.
溶胶-凝胶法将香味和香气化学物质封装在多孔硅基材料中，有可能提供具有新颖独特有益特性的香味和调味材料。无定形溶胶-凝胶 SiO2 是无毒和安全的，而将精细化学品溶胶-凝胶包埋在其内部孔中会导致包埋活性剂的显著化学和物理稳定化，从而拓宽了化学不稳定的精油的实际应用。通过回顾各种香味和调味溶胶-凝胶的制造进展，我们展示了不同的合成策略如何提供适合实际应用的先进材料，这些材料具有重要的健康和环境效益。
