It is not known how to extract carotenoid- which has a high value -optimally from palm oil  mesocarp fiber (POMF). The research objective was to determine the optimization of oil extraction from POMF waste and to determine the optimization of carotenoid extraction from POMF oil. The research was carried out in 2 stages: The first stage was oil extraction from the POMF with the treatment factor ratio of hexane to the weight of the POMF and the extraction time. Stage 2 Optimization of carotenoid  extraction using the solvolitic method with treatment: Minor solvent types Methyl ester (Me) caprylate-caprate (C8 –C10) and Me laurate-myristate (C12-C14) and minor solvent concentrations of 0.1% and 0, 25%. Parameters analyzed were: oil content, Deterioration bleaching of index (DOBI), and carotenoid concentration. Optimization ratio between hexane and POMF weight is 1:40 (vol / g) with an oil content of 2.938%. Optimization of extraction time for 100 minutes with 4.104% oil content. Optimization of carotenoid extraction is by using minor solvent Me C8-C10 with a solvent amount of 0.1% which results in a carotenoid concentration of 302.442 ppm and DOBI of 5.74. The increase in caroten concentration resulted from saponification reached 114.2 times from the carotenoid concentration in POMF oil.

Two Stages

Mesocarp fiber palm oil industrial waste can be processed into pulp, but this fiber still contains oil with varying levels. The difference oil content in fiber affects the amount of cooking solution required to make mesocarp waste into pulp. This study consists of two stages, namely the pretreatment stage of oil extraction to obtain variations in oil content in the mesocarp fiber waste and the delignification stage using the NaOH-ethanol solution with the ratio of solids:solvent is varied to 1: 8, 1:10 and 1:12. Oil content of the fiber was analyzed, it is consist of 9,5% oil. To vary the oil content, the fibers are soaked in ethanol at room temperature and the levels drop to 7%. And soaking at 40°C can lower the oil content drop to 2%. The obtained pulp had the largest cellulose content 50.77% from delignified product from fiber with 7.6% oil content and solids:solvent ratio: 1:10. While the lowest lignin that was 7.39% obtained at 2.5% oil content. In the delignification process with ratio 1:12, pulp produced is decreased in cellulose content and from FTIR results it is known that it occurs because of the degraded cellulose during the delignification process.

In the small-scale dry oil extraction from palm fruit used by palm oil mills, mixed crude palm oil (MCPO) is extracted using a single screw press. The oil palm meal (OPM) by-product can be used as alternative feed for ruminants. Three parameters in further solvent extraction of oil are the ethanol-to-dried oil palm meal (DOPM) ratio (4.9–30.1 g.g-1), the extraction time (0.2–18.8 min), and the speed of stirrer (48–552 rpm). These parameters were optimized to for maximum oil yield by response surface methodology (RSM) while employing hydrous ethanol as the solvent. In our laboratory-scale oil extraction, the maximal experimental yield was 10.27 wt.% under the recommend condition: 20.1 g.g-1 ethanol-to-DOPM ratio, 11 min extraction time, and 300 rpm speed of stirrer. Moreover, prototype-scale oil extraction was tested with recirculated miscella for effects of the number of cycles on oil extraction from fresh DOPM. The results showed approximately 17.4 wt.% oil yield from 5000 g DOPM at the conditions recommended based on laboratory-scale experiments. In this study, recirculated miscella was used to extract oil from fresh DOPM. The first four cycles of oil extraction were almost as efficient as with fresh ethanol. Moreover, the protein content in the defatted oil palm meal (DFOPM) improved with oil extraction, because residual oil in DOPM was removed. The DFOPM should have less rancidity and longer shelf-life than DOPM.

There was a good correlation between the experimental values observed and predicted by the model, indicating that the fit of the model was satisfactory and it can be inferred that the increase of the wort concentration and the nutritional supplementation with the palm oil reached an ethanol volumetric productivity of 0.55 g/L.h and an apparent degree of fermentation of 50.20 %. </P><P> Conclusion: Therefore, it can be concluded that our study demonstrates that nutritional supplementation with palm oil is an alternative and promising option for the breweries to increase productivity. There are recent patents also suggesting the advantages of using alternative nutritional supplements in beverage production.

This research was conducted for evaluation of contamination of pig fat on vegetable cooking oil using transmission polarization method. The sample used is palm oil that has been contaminated with chicken oil and pork oil, with variations of chicken oil and pork oil content. The light source used is a green laser with a wavelength of 532 ± 10 nm. Measurements are made by observing the change in the transmission polarization angle that occurs when no external electric field is provided and by external electric field generated from two copper plates given a voltage of 0-6 kV. Test results show that palm oil contaminated with pig oil has the greatest change in polarization angle compared to pure palm oil and palm oil that has been contaminated with chicken oil. This is because the content of saturated fatty acids in pig oil is greater than pure palm oil and chicken oil. With these results, the transmission polarization method is expected to become a method for the evaluation of halal of cooking oil.Keywords: Transmission Polarization, Electrooptics, Cooking Oil, Impurities of Lard, Halal

Pomelo Peel

Pomelo peel-derived essential oils have been gaining popularity due to greater demand for stress relief therapy or hair care therapy. In this study, we first performed optimization of parameters in the pomelo essential oil extraction process on a pilot scale to gain better insights for application in larger scale production. Then extraction kinetics, activation energy, thermodynamics, and essential oil quality during the extraction process were investigated during the steam distillation process. Three experimental conditions including material mass, steam flow rate, and extraction time were taken into consideration in response surface methodology (RSM) optimization. The optimal conditions were found as follows: sample weight of 422 g for one distillation batch, steam flow rate of 2.16 mL/min and extraction time of 106 min with the coefficient of determination R2 of 0.9812. The nonlinear kinetics demonstrated the compatibility of the kinetic model with simultaneous washing and unhindered diffusion with a washing rate constant of 0.1515 min−1 and a diffusion rate constant of 0.0236 min−1. The activation energy of the washing and diffusion process was 167.43 kJ.mol−1 and 96.25 kJ.mol−1, respectively. The thermodynamic value obtained at the ΔG° value was −35.02 kJ.mol−1. The quality of pomelo peel essential oil obtained by steam distillation was characterized by its high limonene content (96.996%), determined by GC-MS.
