Abstract: | Investigation and modeling of osmotic dehydration parameters on antioxidative activity of peach samples in combined dehydration methods of osmotic dehydration and lyophilization are done to produce the final product of preserved and enhanced antioxidative activity. Antioxidative activity of dehydrated peach samples was investigated by measuring DPPH radical scavenging capacity, and response surface methodology for developing mathematical models was applied. The results showed that combined osmodehydration and lyophilization processes have led to the increased antioxidative activity of dehydrated peaches samples. All three investigated osmodehydration process parameters affected the increase of DPPH values, where process time was found to be the most influential parameter. Maximal obtained DPPH value of 18.25% was achieved in osmotic dehydration process of 5 hours, in 80% concentration molasses, at a temperature of 50 °C and successive 5-hour lyophilization process. Developed mathematical model of DPPH response of dehydrated peach samples was statistically significant, while predicted and observed responses had good correlation, allowing good prediction of the peach samples' antioxidative activity. |
