Preliminary Study on Sweetness-rising Experiment of Mango after Picking

[Objective] The aim was to study the sweetness-rising effect of sucrose-based polymers on mango.[Method] Mango was treated with the 5% sucrose-based polymer solution and the effect of the treatment on the activities of sucrose synthetase(SS) and sucrose phosphate synthetase(SPS) in the fruit were studied.[Result] The SS activity of mango treated by sucrose-based polymers was decreased slowly and it could keep higher activity in the storage period.The treatment delayed the time of the mango SPS activity peak.The SPS activity of the treatment was a little lower than that of the CK in the 5th day,all higher obviously in other time than the CK during the storage period.Meanwhile,the treatment was helpful to accumulate the sucrose in the fruit after the fruit was picked,which increased the soluble solids and total sugar content obviously,improved the fruit quality and the sweetness-rising effect was obvious.[Conclusion] The research laid the foundation for the mechanism discussion on the sweetness-rising effect of sucrose-based polymers on mango.
