Study on effect of rosemary extract on the fresh-keeping of strawberry

Fresh strawberry was used to study the fresh-keeping effect of rosemary extract at various concentrations including 0.10% ,0.30% and 0.60% during storage at room temperature.The results showed that the storage period of strawberries was lengthened after treating by rosemary extract. The reducing sugar content, titration acid content,soluble solids content and VC content were higher than those in the control group,among them with 0.30% of rosemary extract treatment effect was the best,its weight loss rate and the decay rate were 45% and 60% lower than the control group.It was thus clear that rosemary extract as natural antioxidant played a role to the fresh-keeping of strawberry.
