Abstract

Waxing is one way that can be used to extend the shelf life of horticultural products with a relatively low cost. By doing waxing on sapota, it was expected to increase the shelf life of the fruit, so in marketing, sapota quality could be improved. The material used to coat the sapota was beeswax, Sapota cultivar Sukatali ST1 was obtained from the farmers at Sumedang, Jawa Barat. Several concentrations of wax were applied in the preliminary experiment, i.e, 0%, 2%, 4%, 6%, 8%, 10%, and 12% at room temperature. The results indicated that sapota coated with a wax concentration of 10% had longer shelf life of 5 days. In the next stage, the wax applied in the treatments were 9%, 10% , 11%, and without wax coating as control. In addition to room temperature, 15°C storage temperature was also applied as treatment. Observations were made on the respiration rate, weight losses, total soluble solids, hardness, and organoleptic for every 2 days. The results of this experiment saw that sapota coated with a wax concentration of 10% and 11% at room temperature achieved the longest shelf life for 5 days. At 15 ° C storage temperature, longer shelf life of sapota was performed by sapota coated with 9% wax with a shelf life of 11 days.
