Abstract: In order to study the effect of BioSuee film and silicate materials on the rate of color change of fresh apricot fruit produced in Xinjiang during storage and transportation in e-commerce logistics packaging, Xiaobai, Saimaiti and Liguang apricot fruit were commercially packaged with PE film (control), BioSuee film (T1) or BioSuee film combined with microporous crystal silicate preservative (T2). After simulated transportation at (10 ± 1) ℃, the fruits were stored at (25 ± 1) ℃. The concentration of O2/CO2 in the packaging box, ethylene release, the activities of the enzymes related to ethylene synthesis and metabolism, and the contents of pigments, flavonoids and total phenols were determined during storage. The results showed that T2 resulted in a high CO2 contents and low O2 contents packaging environment, delayed the onset of the peak of ethylene production as well as decreased its peak value, slowed down chlorophyll degradation in fresh apricot peel and flesh, and inhibited the synthesis and accumulation of carotenoids, flavonoids and anthocyanins and total phenols. T2 significantly delayed the color change of ‘Saimaiti’ apricots from green to yellow to red, inhibited its yellowing and senescence, maintain its physiological quality during storage and transportation. The results of this study may provide technical support for the storage and transportation of fresh apricot fruit grown in Xinjiang in e-commerce logistics.
