Abstract

Refined Bleached Deodorized Palm Oil (RBDPO) is an oil produced from fresh fruit of the oil palm (Elais guineensis Jacq.) by going through an oil refinery process. RBDPO consists mostly of C16 palmitate fat of 44% which can be applied to shortening products. Shortening is a product derived from RBDPO oil, shortening is a processed product of semi-solid oil emulsions. This study aims to determine the process of making shortening, to find out the results of the analysis of shortening quality, to find out the optimum ratio for making shortening. The ratio of solid fat:RBDPO used in the manufacture of this shortening is 100:0, 80:20, 60:40, 40:60, 20:80, 0:100. Optimum results in the manufacture of shortening based on physical and chemical analysis, obtained with a ratio of 80% solid fat: 20% RBDPO with a moisture content of 0.29%, free fatty acid content of 0.54% and a peroxide value of 0.115 mek O2/kg.

Abstract

81.5 million m3 of palm oil stem is produced every year. Stem fiber can be used as source of cellulose for the making of carboxymethyl cellulose(CMC). CMC is widely used in the pharmaceutical, food, textile and cosmetic industries. The aim of this research is to determine the best reaction time. The procedure consists of 3 initial stages and 2 core stages, namely, sample preparation, reducing the size to 50 mesh, delignification using a 15% NaOH solution for 3 hours, bleaching using a 6% NaOCl solution for 3 hours, alkalization using isopropanol and alkalized with 15% NaOH for 1 hour, in the carboxymethylation stage, sodium monochloroacetate (NaMCA) was added with time variations of 2, 3, 4, 5 and 6 hours. The results showed that 5 hours reaction times produces CMC with degree of substitution of 1.64, a viscosity of 123.5 cP, a pH of 6.1 and a water content of 1.2%.
