Food is often wasted due to real or perceived concerns about preservation and shelf life. Thus, precise, accurate, and consumer-friendly methods of indicating whether food is safe for consumers are drawing great interest. The colorimetric sensing of biogenic amines released as food degrades is a potential way of determining the quality of the food. Herein, we report the use of the fruit extract genipin, a naturally occurring iridoid that reacts selectively with primary amines, as a colorimetric sensor for biogenic amines under conditions that mimic food degradation.

用于生物胺检测的可食用京尼平传感器

由于对保存和保质期的真实或感知担忧，食物经常被浪费。因此，指示食品对消费者是否安全的精确、准确和消费者友好的方法引起了极大的兴趣。食品降解时释放的生物胺的比色传感是确定食品质量的一种潜在方法。在此，我们报告了使用水果提取物京尼平（一种天然存在的环烯醚萜类化合物，可与伯胺选择性反应）作为模拟食品降解条件下生物胺的比色传感器。
