Effects of volatile organic compounds on postharvest brown rot control and sensory quality of peach fruit
Peach fruit is susceptible to Monilinia fructicola during storage and logistics,leading to occurrence of brown rot and fruit quality deterioration.However,the regulatory effects of volatile organic compounds(VOCs)on brown rot remain unclear.This study analyzed the antifungal effects of major VOCs in ripe peach fruit on M.fructicola.The results showed that 12 VOCs involving carvacrol and(E)-2-hexenal were identified to have significant inhibitory effects on the growth of M.fructicola on media.Further research was conducted on the regulatory effects of 12 VOCs on postharvest brown rot of peach fruit.The results showed that the fumigation treatment with VOCs could effectively inhibit the growth of M.fructicola and delay the occurrence of brown rot.Among them,volatile aldehydes exhibited positive effects on maintaining fruit quality.Fumigation with 25 μL/L(E)-2-hexenal significantly inhibited the growth of M.fructicola and reduced brown rot symptoms in peach fruit.Meanwhile,the fruit appearance,ethylene release rate,hardness,total soluble solid content and sensory quality indicators were not affected,therefore maintaining the merchant ability of peach fruit during the postharvest storage.In summary,(E)-2-hexenal has the potential to be developed as a plant-based fungicide,offering quality assurance for the peach fruit supply chain.
