Abstract

ABSTRACT The inhibition process method of sucrose degradation in sugar cane juice was studied by adding kawao root and mangosteen bark. These two preservative agents were traditionally often used to inhibit degradation process of sugar juice. This research was conducted to characterize sugarcane juice and preservative agent (kawao root and mangosteen bark) and to analyze quality change of the juice during incubation. The results showed that the amount of sucrose was higher (10.29%), reduction sugar was 2.43% of glucose and 0.94% of fructose, acid value was 62.5 mleq and pH value was 5.1. Kawao root and mangosteen bark consist of alkaloid, flavonoid, triterpenoid and glycoside in large portion and saponin, fenolic, triterpenoid and steroid in small portion. Changing quality of sugarcane as sucrose content showed that the preservative agent addition can inhibit sucrose degradation, specifically after 80 minute. Preserved sugarcane juice quality is better than those without preservative in terms of reduction sugar content, acid total and pH value. Keywords: kawao root,  mangosteen bark, sugarcane juice, inhibition, degradation.

Abstract

ABSTRACTCastor oil may be dehydrated in such a way that the hydroxyl group, along with a neighboring hydrogen atom, is eliminated, leaving two double bonds. This new form known as dehydrated castor oil (DCO). In the manufacture of DCO, castor oil is subjected to catalytic dehydration. The choice of catalyst is very important in the catalytic dehydration process because the reaction and quality of the resulting product mainly depend on the catalyst. Sodium bisulfate and attapulgite (aluminum-magnesium-silicate) potential to be utilized as catalyst for dehydration of castor oil. The dehydration reaction kinetics of castor oil was investigated with sodium bisulfate–attapulgite mixture as catalyst. The rate of dehydration of castor oil was constructed from experimental data by considering the disappearance of hydroxyl groups. Reactions were carried out at 190, 200, and 210C, and kinetic model was determined for each case. The equilibrium conditions were investigated based on the decreasing of hydroxyl value during the dehydration process for each temperature. In the equilibrium conditions, hydroxyl value of 80.85, 70.81, and 51.59 were reached 150 minutes at 190 and 200C, and 120 minutes at 210C, respectively. The integral method was used to correlate the experimental data. The second order rate equation showed the best fit to the experimental data for all reaction temperature. The rate constant dehydration of castor oil at 190, 200, and 210C are 4,03 x 10-5 [(w%)-1(min)-1], 4,83 x 10-5 [(w%)-1(min)-1], 10,3 x 10-5 [(w%)-1(min)-1], respectively. The activation energy at that condition is 5,24 kcal/mole. Key words : Castor oil, dehydrated castor oil, kinetics

Abstract

ABSTRACTMost commercial grade coconut oils are made from copr.  Most of the copra is dried under the sun in the open air, where it is exposed to insects and mold. The standard end product made from copra is RBD (refined, bleached, and deodorized) coconut oil. Both high heat and chemicals are used in this method. Some alternative technology to make Virgin Coconut Oil (VCO) have been improved and investigated. These are, centrifugal force, fermentation, enzymes, etc. VCO was not made by using of heat and chemicals, it is just refining  by washing with water, filtration, and centrifugation only. In this research, VCO was made by freezing and thawing the coconut milk to destruct the emulsion of coconut milk cream, then centrifugal force was used to separate the oil from coconut milk cream. The problem of this method was high moisture content, so it must be handled by adding of salt. Salt is hygroscopic so it can absorb some water. The characterizations were done for oil moisture content, oil yield, free fatty acid, acid value and peroxide value. The result showed that all of parameters meet the APCC standard.Keywords : Virgin Coconut Oil, VCO, milk cream freezing method.
