Investigation on the Effects of Plant Oils on the Shelf Life Extending, Qualitative and Quantitative Properties of Golden Delicious Apples

This research was conducted in khorasan Agricultural and Natural Resources Research Center in order to study the effects of plant oils on extending the storage life of apples in cold storage. The experimental design was structured as factorial with 4 factors, 3 replicates based on compeletely randomized design. Factor A was apple cultivars (Golden Delicious and Red Delicious), factor B was plant oils (canola, corn, sunflower), factor C was oil concentrations (0, 0.25, 0.5, 1, 2, and 3 percent) and factor D was time of sampling from cold storage (0, 45. 90. 120, 150 and 180 days). After treatment the fruits were transferred to cold storage( temperature 0-1°C and relative humidity 85%). The results revealed that plant oil had significant effect on pH and decay. Besides, oil concentration had a significant effect on pH. total soluble solids (TSS), TSSITA, fruit flesh firmness and decay. The results of organoleptic tests showed that plant oil had significant effect on odor and taste. Also fruit texture was affected by and oil concentration. Overally results indicated that corn oil (2%) caused to maintain the qualitative and sensory characteristics of apple cultivars Golden and Red Delicious after 6 months keeping in cold storage.
