Abstract:

To study the effect of different color bags on Marselan grape berry quality,and providing high quality raw material for vine culture.A complete randomized experiment design was used to analyze the effects of different color bags on berry quality(external quality and internal quality),peel quality and antioxidant activity.100 berries weight,reducing sugar,titrable acid and pH were increased in bags.The red bag increased the total phenols,total flavan-3-ols and total flavonoids,with 376.03,149.78,1 463.53 mg/kg,respectively,there were significantly differences for the total flavan-3-ols and CK,the total flavonoids and the CK.Blue and yellow bag treatments reduced the total phenols,total flavan-3-olsand total flavonoids.Bagging treatment significantly reduced total tannin content,the total tannin content of yellow bag was the lowest at 4.62 mg/g.Generally speaking,bagging treatment decreased DPPH free radical scavenging ability,FRAP(Reducing ability to Fe2+)and ABTS free radical scavenging ability,there was no significant difference for DPPH free radical scavenging ability and FRAP of red bag with CK,yellow bag significantly reduced FRAP,DPPH free radical scavenging ability and ABTS free radical scavenging ability.Correlation analysis showed that the soluble solids were positively correlated with reducing sugar and the sugar/acid ratio,the correlation coefficients were 0.98 and 0.95,respectively.In terms of peel quality,the total phenol was positively correlated with total flavan-3-ols and total flavonoids,the correlation coefficients were 0.95 and 0.98,there was a very significant positive correlation between total flavan-3-ols and total flavonoids,and the correlation coefficient was 0.98.For antioxidant activity,FRAP was very significant positively correlated with DPPH free radical scavenging ability and ABTS free radical scavenging ability free radical scavenging ability,the correlation coefficient were 0.74,0.86,respectively.Soluble solids,reducing sugars and sugar-acid ratio were significantly positively correlated with total anthocyanins,the correlation coefficients were 0.93,0.90 and 0.92,respectively.Principal component analysis was carried out on all the measured indicators,and two principal components with eigenvalues greater than 1 were extracted,the contribution rates of 78.31% and 10.09%,respectively,and cumulative contribution rates of 88.40%,which could basically represent most of the data of quality indicators.Red and blue bags were beneficial to berry quality,and the red bag was better,which can be used in Turpan region.
