    • A method for increasing the stability of a food-grade or pharmaceutical-grade liquid, such as an extracted oil, herbal extract, flavor, color, or volatile chemical component used in the flavor industry, is provided. The method comprises mixing the liquid with an amphoteric polymer, preferably polyvinylpyrrolidone, to thereby infuse the liquid into the amphoteric polymer matrix and form a generally-solid, stabilized product. Optionally, bulking agents, absorbents, and flowing agents can be mixed with the liquid and amphoteric polymer to enhance the properties of the stabilized product. The inventive method is particularly useful for entrapping liquids that are highly volatile, heat sensitive and/or easily oxidizable.
    • 提供了用于提高食品级或药用级液体如风味工业中使用的提取油,草药提取物,风味剂,颜色或挥发性化学成分的稳定性的方法。 该方法包括将液体与两性聚合物(优选聚乙烯吡咯烷酮)混合,从而将液体注入两性聚合物基质中并形成通常为固体的稳定化产物。 任选地,填充剂,吸收剂和流动剂可以与液体和两性聚合物混合以增强稳定化产物的性质。 本发明的方法特别适用于捕获高挥发性,热敏性和/或易于氧化的液体。
