Abstract

PKO (palm kernel oil) is made from palm kernel of Elaesis gueneensis Jacq, which is a mixture of triglycerides. Triglycerides can be converted into a number of derivative products such as mono-diglycerides (MG-DG). MG-DG can be formed by ethanolisis reaction. In this study ethanolisis reaction of PKO was done by adding 96% of technical ethanol containing NaOH 1% (w/w PKO) on PKO solution at a room temperature and a shorter time than the another PKO ethanolisis before. This study was aimed to find the best PKO ethanolisis reaction time in providing products of ethanolisis PKO with yield and high emulsion stability. The experiment was a nonfactorial  and arranged in a complete randomized block design (CRBD) with four replications.  The single factor studied was 7 levels of  the reaction time in which  were 1, 3, 5, 7, 9, 11 and 13 minutes.  The data  were analysed using ANOVA and  further by Orthogonal polynomial on the significant level of 1% and 5%. The results showed that the reaction time ethanolisis had no effect on the yield and stability of the emulsion of fresh coconut milk. The yield of the resulting range between 17.32% - 18.07% and the stability of emulsion ranged between 88.88% - 92.50% during one day and 85.23% - 89.50% during two days. The sensory observation indicated that PKO ethanolisis product can preserve coconut milk for 3 days of storage time with color and scent of fresh coconut milk, and  more stable compared to control.Keywords: emulsion stability, ethanolisis, PKO, time, yield

Abstract

Dietary fiber with a high fermentability can be considered as prebiotic.  Inulin and Fructo-ligosaccharides has been well known as prebiotic resources. Dietary fibre with lower fermentability has a better laxative effect. Green cincau (Premna oblongifolia Merr.) as one of dietary fibre that contains pectin as it’s main gel forming agent. The previous study showed that pectin has a prebiotic function because it could increase beneficial bacteria level in digestion system with fermentability between 50% to 100%. The objective of this research was to compare the prebiotic function of  green cincau’s gel forming agent extract in increasing the lactic acid bacteria and it’s laxative effect (faecal proportion and faecal consistency) with a commercial prebiotic resource (inulin). This research was designed in a completely randomized block design, with a single treatment (different fiber resource added to the diets : green cincau’s gel forming agent extract, inulin, and selulose)). The results showed that green cincau’s gel forming agent extract has a lower prebiotic function but has a higher laxative effect if compared to commercial prebiotic (inulin) with total lactic acid bacteria  was 11.97,   the pH of the digesta was  6.27, and fecal proportion was 6.296%.
