“…The highest biodiesel yield was accomplished when 9:1 alcohol to oil ratio was used (Santos et al, 2009). In a recent study, Shiu et al (2010) used two-step in-situ transesterification with acid catalyst treatment followed by a base catalyst to produce biodiesel from rice bran. They successfully produced high amount of biodiesel in two-step in-situ transesterification in comparison to one step in-situ transesterification (Shiu et al, 2010).…”

“…Triasilgliserol yang terkandung di dalam minyak jika direaksikan dengan NaOH, maka akan menghasilkan asam lemak dan air sehingga membentuk sabun yang dapat memerangkap pengotor berupa getah dan lendir yang tidak diinginkan ada di dalam minyak. Menurut Shiu et al (2010), NaOH dapat meningkatkan rendemen jika konsentrasinya ditingkatkan, tetapi jika ditingkatkan terlalu tinggi akan menyebabkan reaksi saponifikasi yang berlebihan dan mengakibatkan penurunan rendemen.…”

Fish oil production in Indonesia is not only sourced from fish raw materials, but also could be processed by products of canning and fish siege through purification process. The result of purification with one process was not satisfy yet for the parameter oxidation quality fulfillment aspect. Therefore, fish oil by products of fish encircling need to be purified more intensively, such as stratified purification one of them through the process of stratified purification. The aim of this study was to improve the quality of fish oil by-product through stratified purification. The multilevel purification of once purification (P1), twice purification (P2), and three times purification (P3) gives varying results on physical properties, oxidation parameters, and fatty acid profiles. The color of the brightest fish oil was found in sample P2, the lowest density was found in sample P3 (0.63 g /cm3), the highest yield was in P1 sample (44.42%), FFA was lowest in P3 sample (0.37%), The lowest PV in the P1 sample (25.59 meq / kg), the lowest TOTOX in the P1 sample (48.11 meq / kg), and the highest PUFA content in the fatty acid composition found in sample P2 (37.02%). Purified sardine oil extracted from by products of fish stamping by three-stage purification, FFA parameters are able to meet the criteria of IFOS 2014 standards, while for PV, AnV, and TOTOX parameters are able to meet IFOMA standards.

“…As the methanol-to-biomass ratio increased to 90 mL·g −1 , higher total FAME yields were attained (10.04% ± 0.14%) and the EPA yield reached its highest level (4.02% ± 0.17% of total biomass). When the methanol-to-biomass ratio was increased to 120 mL·g −1 , FAME yield decreased to roughly 9.27% ± 0.02%, which suggests that some protein and carbohydrate components of the biomass may have been co-extracted in the excess methanol [26]. In addition, the free fatty acid (FFA) and triacylglycerol (TAG) in microalgae can both be converted to FAME and less methanol is required for FFA dissolution and conversion than TAG.…”

Optimization of One-Step In Situ Transesterification Method for Accurate Quantification of EPA in Nannochloropsis gaditana

Microalgae are a valuable source of lipid feedstocks for biodiesel and valuable omega-3 fatty acids. Nannochloropsis gaditana has emerged as a promising producer of eicosapentaenoic acid (EPA) due to its fast growth rate and high EPA content. In the present study, the fatty acid profile of Nannochloropsis gaditana was found to be naturally high in EPA and devoid of docosahexaenoic acid (DHA), thereby providing an opportunity to maximize the efficacy of EPA production. Using an optimized one-step in situ transesterification method (methanol:biomass = 90 mL/g; HCl 5% by vol.; 70 • C; 1.5 h), the maximum fatty acid methyl ester (FAME) yield of Nannochloropsis gaditana cultivated under rich condition was quantified as 10.04% ± 0.08% by weight with EPA-yields as high as 4.02% ± 0.17% based on dry biomass. The total FAME and EPA yields were 1.58-and 1.23-fold higher separately than that obtained using conventional two-step method (solvent system: methanol and chloroform). This one-step in situ method provides a fast and simple method to measure fatty acid methyl ester (FAME) yields and could serve as a promising method to generate eicosapentaenoic acid methyl ester from microalgae.
