Absorption of free radicals
Analysis of variance showed that these compounds have been affected by the coverage (p‹0.01). Comparison of treatment means showed that the maximum absorption of free radicals in a coating of 60% chitosan + 40%aloe vera and the lowest level in the control sample was observed. Significant differences were not observed between the coverage of 60% chitosan + 40% aloe vera and 100% in absorbance of free radicals.
The absorption changes rate of free radicals showed differences at different days of storage. On all sampling days (days 7, 14, 21) the highest free-radical absorbance was observed with a 60% chitosan + 40% coating, which indicated this type of coverage to have the ability to maintain the favourable properties of kiwi fruit. During different days of sampling the absorption change rates of free radicals were different between samples: the rate on the seventh day was increased with 100% chitosan coverage but with this coverage day 21 free radical absorption was reduced by 15% compared to the seventh day. Similar changes to the 100% chitosan coverage were observed in 80% chitosan + 20% aloe vera. But the 60% chitosan + 40%aloe vera coverage from
