(Z)-3-Unsaturated volatile acids, alcohols, and aldehydes are commonly found in foods and other natural sources, playing a vital role in the attractiveness of foods but also as compounds with chemocommunicative function in entomology. However, a systematic investigation of their smell properties, especially regarding humans, has not been carried out until today. To close this gap, the odor thresholds
(Z)-3-不饱和挥发性酸,醇和醛通常在食品和其他天然来源中发现,它们在食品的吸引力中起着至关重要的作用,而且在昆虫学中还具有化学传递功能。然而,直到今天仍未对其气味特性,特别是对人类的气味特性进行系统的研究。为了弥合这一差距,通过气体确定了(Z)-3-烯烃-1-醇,(Z)-3-烯烃和(Z)-3-链烯酸的同源系列的空气中的气味阈值和气味质量色谱-嗅觉测定法。发现(Z)-3-alken-1-ols和(Z)-3-链烯醛随着链长的增加而变化,从草绿色变为整体的脂肪和柑橘样肥皂性状。另一方面,(Z)-3-链烯酸的气味质量从其俗称的俗气,发汗到类似塑料依次变到蜡质。关于它们的气味效力,发现空气中的最低阈值是(Z)-3-己醛,(Z)-3-辛烯酸和(Z)-3-辛烯醛。
