Influence of photoselective anti-hail nets on the physicochemical and biochemical parameters of the flesh of ‘Florina’ apple cultivar

The present study determined the influence of differently colored photoselective anti-hail nets on the physicochemical and biochemical performance of fruit flesh of the apple cultivar ‘Florina’. In the Food Testing Laboratory at the Institute of Food Preservation and Quality in Plovdiv (Bulgaria), it was found that the physicochemical parameters water soluble dry matter and insoluble dry matter, as well as the biochemical parameters total sugars, sugar-acid coefficient, antioxidant activity, and total polyphenols, have maximum values in ‘Florina’ fruit flesh grown under red net.
A positive linear relationship was found between the analyzed antioxidant activity and content of total polyphenols of the studied fruit grown under differently colored photoselective nets, with a high coefficient of determination – R²=0.889. Maximum values of the parameters active and total acidity were determined in fruit grown under a black net, and minimal values of these parameters were determined in fruit grown under a yellow net.
