The preservation effect of 1 g/L trehalose solution was investigated using cherry tomato as the main ingredient.The decay index,weight loss rate,hardness,pH value,total soluble solids(TSS),titratable acid(TA),vitamin C(Vc),lycopene,reducing sugar and soluble protein of cherry tomato were measured at room temperature.The results showed that 1 g/L trehalose treated cherry tomato significantly inhibited the increase of fruit decay index and weight loss rate,and delayed the decrease of TA,Vc,and soluble protein.In conclusion,trehalose treatment suppressed the rising de-cay index of cherry tomato,significantly improved the storage quality of the fruit and extended shelf life.
