Natural surfactant is developed as fatty acid derivate from natural resources such as palm oil, sunflower oil, and safflower oil. In South East Asia countries, the palm oil is used as the main resources of fatty acid derivate. Seed oil of Morinda citrifolia L. contains unsaturated fatty acid. It is extracted and concentrated. The concentrated fatty acid of Morinda citrifolia L. (CFAMC) is used as deinking surfactant. The CFAMC is analyzed by GCMS for its constituent and its deinking flotation performance is evaluated for yield, brightness, and ERIC of deinked pulp. Based on the old newspaper (ONP) pulp with brightness of 35.84 °ISO, and ERIC of 1982.4 ppm, the deinking flotation performance of CFAMC is approaching the natural surfactant. The brightness increase is 11.36% and 16.35%, and the ERIC reduction is 37.40% and 47.73% for CFAMC and natural surfactant respectively. SEM analysis is provided to see the residual Nanoink particles on the fibers.

There is increasing evidence that the degree of postprandial lipaemia may be of importance in the development of atherosclerosis and IHD. Postprandial lipid, lipoprotein, glucose, insulin and non-esterified fatty acid (NEFA) concentrations were investigated in eleven healthy young males after randomized ingestion of meals containing rapeseed oil, sunflower oil or palm oil with or without a glucose drink. On six occasions each subject consumed consecutive meals (separated by 1·75 h) containing 70 g (15 g and 55 g respectively) of each oil. On one occasion with each oil 50 g glucose was taken with the first meal. One fasting and fifteen postprandial blood samples were taken over 9 h. There were no statistically significant differences in lipoprotein and apolipoprotein responses after rapeseed, sunflower and palm oils, whereas insulin responses were lower after sunflower oil than after rapeseed oil (ANOVA, P = 0·04). The NEFA and triacylglycerol concentrations at 1·5 h were reduced when 50 g glucose was taken with the first meal (ANOVA, P < 0·0001 and P < 0·05 respectively), regardless of meal fatty acid composition. In conclusion, the consumption of glucose with a mixed meal containing either rapeseed, sunflower or palm oil influenced the immediate triacylglycerol and NEFA responses compared with the same meal without glucose, whereas no significant effect on postprandial lipaemia after a subsequent meal was observed. The fatty acid composition of the meal did not significantly affect the lipid and lipoprotein responses, whereas an effect on insulin responses was observed.

Oils extracted from various parts (seed and aril) of Ravenala madagascariensis S. (Musaceae) were studied for their fatty acid and sterol contents. Results showed that these oils, partially solidified, may be used as edible food products and that oil contents of seed and aril are respectively 4.1% and 68.7%. These oils contain rather high levels of oleic (39%) and palmitic (34–42%) acids. Sterol fraction analysis of seed oil reveals 7 sterols, mainly beta-sitosterol (65%), whereas sterol fraction of aril oil reveals 12 sterols, mainly stigmasterol (18%) 24-methyl-5 alpha cholest-7 en -3-beta ol (16%), apha-spinasterol (28%) and delta-7 avenasterol (19%). This study showed that Ravenala madagascariensis S. oils have a fatty acid composition which is intermediary between the palm oil and cocoa butter composition. They form a possible new source of vegetable butter.

Biodiesel Synthesis

The needs of fuel increase along with human needs. However, domestic fuel production is decreasing every year and forcing to carry out import activities to suppress domestic oil drilling. Fuel production is also carried out by using palm oil to be used as biodiesel. However, on further inspection, the use of palm oil is not entirely effective. This is because palm oil is also used as a base for oleochemical and food products. Therefore, we need the right solution to overcome this problem, which is by developing biodiesel as renewable energy from kesambi seed oil. Kesambi oil is obtained from poisonous plant,so it is not used as an ingredient in other products. Then, this potential can be focused as a source of oil for biodiesel production. Kesambi seed oil analyzed with GC-FID to analyze its fatty acid contents. The result of this analysis is kesambi seed oil have cis-10-pentadecenoic and heptadecanoic acids as its dominant acid. Before the main process, kesambi seed oil was pretreated through degumming process using 1% phosphoric acid to remove the gum in kesambi oil. Then, the free fatty acid levels (%FFA) measured using the naoh titrant and have %FFA that meets the standards, 0.37%, which still within the permissible limits to continue the transesterification process. Transesterification process used variety of catalyst (cao) concentration as its variable. The catalyst concentrations used were 0.5%, 1%, and 1.5%wt of oil. The biodiesel synthesis resulted in the amount of yield obtained from the 0.5% catalyst concentration is 54,9%, 1% catalyst concentration is 81,1%, and 1.5% catalyst concentration is 70,2%. The quality of biodiesels also met the requirements of SNI 7182:2015 and ASTM D7467.

Pure phytosterols that are sparingly soluble in oils were subjected to a transesterification reaction using the catalyst sodium methylate in a mixture of palm stearin: palm oil: sunflower oil. As a comparison, transesterification was performed under the same conditions without the addition of phytosterols. To determine the qualitative composition of the mixture transesterified with phytosterols, analyzes were performed on the fatty acid composition, sterol composition, and melting point. The resulting product differed from the control by the presence of a characteristic odor, sterol composition, melting point.

Glycerin residue is waste oleochemical industry that still contain glycerin. To produce quality and maximum quantity of glycerin, then research the effect of pH acidification using phosphoric acid. Glycerin analysis includes the analysis of pH, Fatty Acid and Ester (FAE), and analysis of the levels of glycerin. The maximum yield obtained at pH acidification 2 is grading 91,60% glycerin and Fatty Acid and Ester (FAE) 3,63 meq/100 g. Glycerin obtained is used as a plasticizer in the manufacture of bioplastics. Manufacture of bioplastics using the method of pouring a solution with varying concentrations of starch banana weevil (5% w/v and 7% w/v), variations of the addition of glycerin (1 ml, 3 ml, 5 ml and 7 ml), and a variety of gelatinization temperature (60°C, 70°C, and 80°C). Analysis of bioplastics include FTIR testing, tensile strength that is supported by SEM analysis. The results obtained in the analysis of FTIR does not form a new cluster on bioplastics starch banana weevil, but only a shift in the recharge area only, it is due to the addition of O-H groups originating from water molecules that enter the polysaccharide through a mechanism gelatinitation that generates interaction hydrogen bonding strengthened. The maximum tensile strength of bioplastics produced at a concentration of starch 7% w/v, 1 ml glycerine and gelatinization temperature of 80°C is 3,430 MPa. While the tensile strength bioplastic decreased with increasing glycerin which can be shown from the results of SEM where there is a crack, indentations and lumps of starch insoluble.

Current paper reveals the impact of thermal treatment on the quality of two seed oils – pumpkin and melon compared to the quality of the most used oil – sunflower oil. Conventional and microwave heating were used for processing the oils. The duration of the thermal treatment was 9, 12 and 18 min for the conventional heating. The microwave heating was performed with two microwave powers of the equipment (600 W and 900 W) for 3, 6, 9 and 12 min. At every stage of the thermal processing were determined acid and peroxide value, the absorbance of the oils at 232 and 268 nm, tocopherol and fatty acid composition. It was observed that the degree of oxidation of the examined oils during microwave and conventional heating increased with the duration of the thermal process and the power of the microwaves. Also, the two methods of heating had a little impact on the processes leading to the formation of free fatty acids. Total tocopherols of the melon seed oil were more stable to thermal treatment. The amount of linoleic acid decreased in the pumpkin and sunflower oils during microwave treatment, while that of oleic and palmitic acid relatively increased. The biggest change in the fatty acid composition of both oils was found during microwave heating at 900W. The changes in fatty acid composition of thermally treated melon seed oil were insignificant. Overall, melon seed oil was observed to be more thermally stable than pumpkin and sunflower oils.
