Strawberry aroma is beneficial to the quality of the fruits and derived foods, as well as consumer health. Light quality affects strawberry aroma emission, which can be conveniently supplied by colored light‐quality selective plastic films. To produce high‐aroma strawberry by using optical colored light‐quality selective plastic film, the aroma emission and key gene expression were investigated under transparent (T), red (R), yellow (Y), green (G), blue (B), and purple (P) films. Moreover, the content of sugar, soluble proteins, and anthocyanins as well as total titratable acidity was also investigated. Strawberry released an abundance of aroma, mainly including esters, terpenoids, alkanes, alcohols, acids, aldehydes, and ketones. T, R, and Y films increased FaAAT (alcohol acyltransferase) expression to promote ester emission. Among strawberry aroma components, trans‐nerolidol showed the maximum emission amount. R film promoted its emission by increasing FaNES1 (nerolidol synthase) expression. Meanwhile, R film was also beneficial to the accumulation of reducing sugar, sucrose, total sugar, anthocyanins, and soluble proteins, and total titratable acidity. Therefore, high‐aroma strawberry can be produced by using R light selective plastic film, with increasing fruit chemical properties.

不同颜色的光质选择性塑料膜下草莓的香气和特定风味的变化

草莓香气有益于水果和衍生食品的质量以及消费者健康。光线质量会影响草莓的香气散发，可以通过彩色的光线质量选择性塑料薄膜方便地提供。为了使用光学彩色光质选择性塑料膜生产高香气草莓，在透明（T），红色（R），黄色（Y），绿色（G），蓝色（B）下研究了香气释放和关键基因表达）和紫色（P）胶片。此外，还研究了糖，可溶性蛋白质和花色苷的含量以及总滴定酸度。草莓释放出丰富的香气，主要包括酯，类萜，烷烃，醇，酸，醛和酮。T，R和Y电影增加了FaAAT（酒精酰基转移酶）表达来促进酯释放。在草莓香气成分中，反式橙花醇释放量最大。R胶片通过增加FaNES1（神经寡糖合酶）表达来促进其发射。同时，R膜还有利于还原糖，蔗糖，总糖，花色苷和可溶性蛋白质的积累，以及总滴定酸度。因此，可以使用R光选择性塑料膜生产高香气的草莓，并提高果实的化学特性。
