Özet
The aim of this study was to determine the effects of different doses (0.4, 0.8, 1.2, 1.6 and 2.0 mM) of putrescine treatments on the post-harvest weight loss, decay, firmness, soluble solids content, titratable acidity, pH, respiration rate, L* , a* , b* , Chroma and hue angle and phenolic compounds, organic acids and vitamin C content of kiwi (cv. Hayward. The fruits were kept in a cold storage at 0 +/- 0.5 degrees C and 90 +/- 5% relative humidity for 140 days. The weight loss, soluble solids content, increases in respiration rate and high decreases in fruit density, firmness, and titratable acidity were detected in the control group fruits during storage. Among the putrescine treatments, 1.2 mM concentration was observed to be more effective than other concentrations and providing better protection for organic acids, while treatment with 2.0 mM was determined to be providing more protection in preventing the loss of vitamin C. The dominant organic acid of kiwi was determined as citric acid, followed by malic acid, succinic acid and vitamin C. Similarly, it was determined that treatment with 2.0 mM putrescine prevented the loss of phenolic acid and flavonoid more than the control group and other treatments. It was determined that the most common compound found among phenolic acids in kiwi was protocatechuic acid, followed by chlorogenic acid. At day 140 of storage, the minimum change was observed in protocatechuic acid with the application of 1.6 mM putrescine dose, while chlorogenic acid and catechin were the most conserved compounds under treatment with of 2.0 mM.
