Optimization of Bleaching Process - lipidlibrary.aocs.org

Some consider bleaching the "safety net" of the refining process in that it is the last operation in the oil refining process before going to deodorization. As the focus of this paper would suggest, optimization of the bleaching process is considerably important to both (1) achieving high quality refined oil products and (2) the economic ...

Extraction – European Biomass Industry Association

In mechanical extraction method, techniques such as mechanical pressing, bead mi lling, and homogenization are used and accounts for large scale of cell disruptions. Mechaning pressing puts high pressure on the cells being extracted, ruptures the cell wall, allowing the intracellular lipids to be extracted and co llected. Homogenization ruptures the cell wall by forcing the cells through a ...

Consequently, the oil was extracted by n-hexane for 60 min. ...

Suitability of Soxhlet Extraction to Quantify Microalgal ...

gravimetric lipid content was considerably greater (up to sevenfold) than the FA content of the crude lipid extract. FA content from Soxhlet lipid extraction and ISTE were similar in 12/18 samples, whereas in 6/18 samples, total FA content from Soxhlet extraction was less than the ISTE procedure. Re-extraction of residual biomass from Soxhlet

Determination of Buffalo and Pig "Rambak" Crackers Using ...

Extraction of lipid fraction from Rambak crackers: Rambak crackers were purchased from traditional market in Yogyakarta. Rambak crackers are smooth such as powder before Soxhlet extraction. The extraction process involved the use of hexane as an extracting solvent as described by Association of Official Analytical Chemists, AOAC (1995). The ...

ABSTRACT - biodieseleducation.org

extraction uses chloroform or a mixture of methanol and chloroform to extract neutral lipids, and methanol as the solvent to extract polar lipids in cell membranes (Ferraz et al., 2004). On the other hand, Soxhlet extraction uses hex-ane and can only extract neutral lipids (Ferraz et al., 2004).

amount of lipids remaining after a two-phase extraction. Thus our net yield from a two-phase extraction of the Soxhlet material (5%) plus the lipids obtained from the acid extraction of the Soxhlet residue (4.576) is 9.5%. To compare this net yield with published values of 8% for Soxhlet extraction alone (8, 13), the published yields must

ABSTRACTThe substitution of rat meat (non-halal meat) in beef-based sausage products is illegal practice. This study was aimed to develop Fourier transform infrared (FTIR) spectroscopy in combination with chemometrics for analysis of rat meat in sausage employing three different lipid extraction techniques. Lipid was extracted from the sausages using Bligh and Dyer, Folch, and Soxhlet methods.
