Pengemasan dan Penyimpanan Dingin Kelapa Kopyor untuk Mempertahankan Mutu

Abstract

The objectives of this research were to study the influence of packaging material and the temperature applied during storage on the quality of kopyor coconut, to predict the shelf-life, and to determine the best packaging material and the storage temperature to keep the kopyor coconut. Research material is kopyor coconut obtained from Kalianda South Lampung. Kopyor coconut packaged in plastic film type Polyamide (PA), Polypropylene (PP), and High Density Polyethylene (HDPE) each weighing 60g. The quality parameter observed are free fatty acids (FFA), total microbes, and sensory characteristics including color, flavor, and taste. This research us Randomized Complete Design with two factors. The first factor was the packaging material with three different types (PA, PP, HDPE), and the second factor was the storage temperature at two levels of 5±2OC and 10±2OC. The shelf-life was predict using Partially Staggered Design (PSD) technique. Principal Component Analysis (PCA) technique was used to determine the best treatment. The results showed that the type of plastic packaging and storage temperature gave an effect on the total microbes, and organoleptics of color, flavor, and taste. PA packaging is the best packaging can be maintained the quality of organoleptic and reduce the microbe growth. The storage temperature of 5±2OC can maintain quality of kopyor coconut better than 10±2OC temperature. Based on PSD method and total microbe as critical parameters, the shelf-life of kopyor coconut at 5±2OC is 27, 26, and 17 days for plastic PA, HDPE, and PP packaging, respectively.
