TI  - Effect of pectin-wax coating on the quality of fresh-cut apples
AB  - The effect of edible coating using pectin-wax mixture and its incorporation with pistachio hullextract were investigated on the quality characteristics of fresh-cut apples. For this purpose,fresh-cut apples were treated with citric acid (control), pectin-wax (PW) mixture and pectinwaxmixture containing pistachio hull extract (PWE). The samples were kept under twoseparate temperatures at 5 °C for 8 days and at 20 °C for 32h. Changes in weight, color, totalphenolic content, were examined at different time points along storage time. Resultsindicated that the apple pieces coated with PWE showed the lowest increase in browningindex followed by samples coated with PW. The applications of coatings were effective ondelaying the degradation of samples’ colors. The effect of coating fresh-cut apples with PWEwas less pronounced on a* values than on L* and b* values. Furthermore coating with PWwas affected L* values significantly. The temperature was also a factor affecting the samplescolor. It was observed that samples kept at 5 °C have maintained the color coordinates.Weight loss was observed significantly in uncoated samples comparing to those prepared withcoating. The weight losses were 4.77±0.21% and 6.60±0.24% at 20 °C, while these values were17.29±0.54 and 26.81±0.60 at 5 °C for coated and uncoated samples respectively. The coatingswere effective in maintaining phenolic components. Total phenolic contents were187.86±0.95 and 199.80±0.99 mg GAE 100 g-1 apple at 5°C for uncoated and coated samplewith pistachio hull extract, respectively. However, phenolic contents were recorded as128.89±0.80 and 130.53±0.86 mg GAE 100 g-1 apple after 32 h storage time at 20 °C foruncoated and coated sample with pistachio hull extract, respectively.
