Effects of Cassai Oil on the Shelf-life and Quality of Sweet Cherry Fruits
To investigate the effects of cassai oil on the shelf-life and quality of sweet cherry fruits in ambient temperature (26℃ to 30℃),the fruits of Brooks sweet cherry were fumigated with cassai oil (10,15 and 20μL· L-1).The decay rate,weight loss,firmness,soluble solid content,titratable acidity,fruit anthocyanin and stalk chlorophyll content were analysed during storage.The treatment by cassai oil fumigating is an effective means to control fruit decay,sustain the weight and firmness loss,as well as keeping higher anthocyanin content in fruit and chlorophyll content in stalk.There were no significant differences on soluble solid content and titratable acidity of fruit among treatment during the whole experiment period.15μL·L-1 cassai oil treatment can obviously inhibit the decay of sweet cherry fruit..Fruit injury was found while cassai oil concentration was over 30μL· L-1.The results showed that the treatment by cassai oil fumigation could effectively prolong shelf-life of sweet cherry fruit in ambient temperature.This reaserch would provides a necessity to guide on developing and using essential oil on preservation and fresh-keeping for sweet cherry.
