Abstract

Dry fractionation will produce a fraction of olein and stearin with different composition of high melting and low melting as well the distribution of triacylglycerol (TAG) in the form of trisaturated (St3), disaturated (St2U) and monosaturated (StU2). This research aimed to study the effect of critical cooling rate and crystallization temperature on the composition and profile of TAG changes as well the melting properties of the fractionated coconut oil products. Coconut oilwas heated at 70°C then cooledat differentcooling rate to reach various crystalization temperatures. The oil was then stirred at 15rpm and allowed to crystallize at different period of time, and finally fractionated by vacuum filtration using Whatman #40 paper. Fractionation temperatures were the same as crystalization temperatures. The results showed that the critical cooling rate was proportional to the solid-like to liquid-like ratio, the content of St3 and SFC profile of olein fraction but inversely proportional to the content of St2U and StU2 TAG. Interval crystallization temperature between 21.30 and 21.73 °C produced the S/L ratio, the content of St3 TAG and SFC profiles of olein fractions lower and the content of St2U and StU2 TAG higher than the temperature interval below or above it. Coconut oil fractionation more effective in higher crystallization temperature or lower critical cooling rate. In these cooling treatments, St3 TAG which has high melting pointwould be concentrated at stearin fraction, while St2U and StU2 TAG and MCTwould be at olein fraction. Therefore, it will increase melting properties of stearin fraction and decrease olein fraction.

Abstract

Coleus amboinicus (Lour) (torbangun) has been used traditionally as a breast milk stimulant, flavoring agent in many cuisines, and reported to possess many pharmacological values. The aim of this study was to explore the utility of the Pressurized Liquid Extraction (PLE) technique to identify the phytochemical contents of torbangun. In this study, total phenolic content and flavonoid in torbangun were determined using spectrophotometric method. The GC-MS analysis was used to identify the chemical constituents of torbangun, which was sequentially extracted with a wide range of solvent or solvent mixture from nonpolar-moderately polar and finally polar solvent. Total phenolic and flavonoid contents in the methanol extract of torbangun were 42.17±2.96 mg GAE/g and 11.20±0.58 mg QE/g, respectively. The identified chemical constituents in torbangun were sugar, hydrocarbon, ketone, terpenes, phenolics, fatty acid, fatty alcohol, steroids, alkaloids, and others, whereas the dominant constituents were phenolic compound, alkane, and sugar. In conclusion, this study demonstrated the effectiveness and rapid extraction of the PLE technique. Many valuable compounds in torbangun were extracted using gradual composition of solvent and were able to identify certain compounds in different polarities of solvents that are important in functional food preparation, pharmaceutical, and metabolomics research. Keywords: bioactive, extract, nontoxic, plant, solvent
