Abstract

The aim of the research was to determine the shelf life of white oyster mushroom flour in polyethylene plastic packaging with the Arrhenius method. The study was arranged descriptively with two replications. White oyster mushroom flour was stored at three storage temperature conditions, i.e. 30oC, 40oC and 50o C in polyethylene plastic packaging with a thickness of 0.03 mm and stored for one month (28 days). Observations were made on water content, levels of free fatty acids, protein content, flavour and color of white oyster mushroom flour every once a week i.e. on days 0, 7, 14, 21 and 28. The data obtained were used to determine the shelf life of white oyster mushroom flour using acceleration (accelerated storage) method with Arrhenius equation model using Microsoft Excel software. The results showed that the shelf life of white oyster mushroom flour in polyethylene plastic packaging thickness of 0.03 mm using the Arrhenius method was set at a temperature of 30o C based on the parameters of the zero reaction protein content, which was 130.67 days (4.3 months). White oyster mushroom flour in polyethylene plastic packaging thickness of 0.03 mm during storage temperature of 30o C, 40o C, and 50o C tends to decrease protein content, color and aroma, but experience an increase in free fatty acid levels. White oyster mushroom flour in polyethylene plastic packaging at 30o C tends to increase in water content during storage, and decreased water content at 40o C and 50o C.

Abstract

The purpose of this study was to evaluate the defects, moisture content, flavor, and overall acceptance of Robusta coffee from 20 coffee producers in Tanggamus Regency. Taste testing involved some expert panelists. The data were analyzed descriptively. The results showed that as much as 70% of coffee quality was following SNI 01-2907-2008. The defect value of coffee was at the quality level of 5 until the inferior original quality (“kopi asalan”). The main percentages of the defects were broken seeds, brown beans, black seeds and then followed by hollow seeds. The water content of the coffee was varied between 5.07-7.27.  The taste of coffee was dominated by green/grassy, the average taste was slightly bitter, the colors ranged from brown, black and cinnamon-like color, while, the overall acceptance was somewhat like. This results indicated that standard operating procedure is required to be implemented by coffee producers (IKM) in Tanggamus Regency to improve the quality of the coffee.
