Abstract

(The Use of Tapai Yeast and Papaya Fruit Sap on Coconut Oil Extraction By Fermentation)ABSTRACT. In Aceh, coconut oil extraction is traditionally done through a natural fermentation of fresh coconut meat to produce simplah and pliuk u oil. Simplah oil and pliek u oil have high level of moisture content, free fatty acids, and peroxide value due to long fermentation process. The study was conducted by using the fresh shredded coconut meat. Then mixed with tapai yeast and papain from immature papaya fruit sap and were fermented for 48, 72, and 96  hours respectively. The yield of coconut oil produced in this study was from 8.53 % - 19.0 %, moisture content 12.58 - 2.66 %, free fatty acid content 3.29 % - 11:55 %, and peroxide value 0.76 - 1.75 mg O2/g of oil sample. The highest yield of coconut oil was obtained in the control treatment which significantly different from other treatments. The highest moisture content and free fatty acid were obtained on the treatment of using tapai yeast during fermentation process of coconut oil and did not meet the requirements set by the Indonesian National Standard (SNI 01-2902-1982), while the peroxide value of coconut oil produced in various treatment have met the criteria of SNI. The average organoleptic score of coconut oil color 3.38 (from moderate to clear) which the highest score was obtained on fermented coconut oil with the addition of tapai yeast. The highest hedonic score of aroma was found in the coconut oil fermented with the addition of papain from papaya fruit sap with fermentation time of 48 hours is 2.9 (from dislike  to moderate).

Abstract

The study aimed to evaluate the influence of blanching methods to the quality of oyster mushroom flour. The treatments were non-blanching, hot water blanching and steam blanching at 3 replications. The amount of mushroom used for each treatment was about 500g. The mushroom was cut into cube shape sizing approximately 1cm. The drying process was conducted by using solar tunnel dryer type Hohenheim Aceh. The temperature and relative humidity were recorded by using proportional integral derivative (PID) controller connected to the outlet fans. The moisture was analyzed by using a moisture analyzer XY105MW, while color was examined by using a colorimeter LS171. The protein content of mushroom flour was determined by Kjeldahl method, and the ash content was identified by dry ashing method at temperature of 400-550°C. Data were analyzed by using analysis of variance (ANOVA). Results showed that the blanching method could cut the drying time approximately for 3h. The ANOVA had shown a significant influence of blanching methods to the moisture, yield, ash content and whitness index (WI). However, there is no significant influence of treatments to the protein content. This study suggests the hot water blanching in processing the oyster mushroom flour because it produced the best performance of oyster mushroom flour i.e moisture of 5.78%, yield of 6.26%, protein content of 19.32%, ash content of 4.99% and whitness index of 63.88. Further study is necessary to determine the best combination of temperature and drying time in order to increase the yield.
