Title

Effect of soy protein isolate and TiO2 edible coating on quality and shelf-life of grapes varieties Hosseini and Ghezel Ozom

Pages

  29-41

Abstract

 The most important post harvesting factors that limiting grape berries after post harvesting are water losing and fungal decay. In this study, effect of titanium dioxide (TiO2) and Soy protein isolate Edible coating against postharvest decay and increasing the storage life of table grape cultivar was investigated. Uniform clusters with no disease and physical damage were packed with coated and uncoated (control) TiO2 nanoparticles. Then clusters were maintained for 31 days in cold storage at 0 ± 1 ° C and RH 90 ± 5%. Grape berries abscission rate, total soluble solids (TSS), titratable acidity (TA), total phenolic content, color and clarity of grape berries, pH, antioxidant activity and total sugar characteristics were measured at intervals 6 days. The statistical analysis of results showed that the TiO2 nanoparticles treatment had significant effects in cluster and grape berries weight losing, fungal infection, TA, total phenol content and coefficient of ripening. This treatment had best flavor, quality, appearance and marketability compared with the samples without TiO2 nanoparticles treatment. In addition, the samples that treated with TiO2 nanoparticles showed higher TSS, TA, antioxidant activity, total sugar and total phenolic content. In the present study, two varieties of Grapes treated with TiO2 nanoparticles in the comparison of control samples had higher quality at the end of the storage period.
