标准摘要
[中文适用范围]： ISO 15788 的这一部分规定了甾二烯，特别是豆二烯的测定方法。 甾二烯是在漂白过程中以及部分在蒸汽洗涤和除臭过程中由甾醇脱水形成的。 该方法还适合作为检测初榨油（例如初榨橄榄油）中精炼植物油的存在的筛选方法。 注：ISO 15788-1 是测定植物油中豆二烯的参考方法，而 ISO 15788 的这一部分可用作快速筛选方法。 鉴于该方法的精确度（见附录A），接近国际法规（IOOC、EC）采用的限量的初榨橄榄油样品可以通过ISO 15788-1中给出的GLC方法进行验证。 [外文原描述]： ISO 15788-2:2003 specifies a method for the determination of steradienes, especially stigmastadienes. Steradienes are formed by dehydration of sterols during bleaching and also partially during steam washing and deodorization. The method is also suitable as a screening method to detect the presence of refined vegetable oils in virgin oils such as virgin olive oil.
