Go down to the bottom of this post if you're interested in learning how the Soxhlet extractor works.* Although we were enthralled by the sheer ingenuity of this piece ...
Aug 01, 2013· INTRODUCTION. Lipids from marine organisms have received increasing attention because of their positive effects on cardiovascular diseases that are mainly a result of the biological and pharmacological role of polyunsaturated fatty acids (PUFAs) (La Guardia et al. 2005, Calder & Yaqoob 2009).Furthermore, other nutritional properties, such as high-quality protein, iron, zinc, copper, and ...
Keywords: lipid, Soxhlet, extraction, rainbow trout. Introduction The fast-growing rates of aquaculture reproduction of salmon due to the high content of polyunsaturated fatty acids (an average of 2.3 grams per 100g fillets) increase the interest of scientists and stimulate new researches on the chemical composition and the development of new ...
Soxhlet extraction is likely the oldest form of organic matter extraction. Archeological evidence from Mesopotamia places the use of a Soxhlet-like device that utilized hot water at ~3,500 BC 1,2.Modern Soxhlets use sophisticated blown glass condensers and organic solvents in this "continuous" extraction method (Figure 2).Solvent is refluxed from a round-bottomed flask upward into a condenser ...

In this study the extraction of lipid from sardine fish waste was carried out using microwave-assisted extraction (MAE) and compared with Soxhlets and Hara and Radin methods.
2.3.3 Total lipid. Lipid content was determined according to standard methods 21 with the Soxhlet extraction using petroleum ether. The collected fat was expressed as the mass percentage of extracted lipid to the original sample mass (5 g) used in the analysis.
The by-products generated from the processing of fruits and vegetables (F&V) largely are underutilized and discarded as organic waste. These organic wastes that include seeds, pulp, skin, rinds, etc., are potential sources of bioactive compounds that have health imparting benefits. The recovery of bioactive compounds from agro-waste by recycling them to generate functional food products is of ...
Moringa oleifera seed powder. 0–20%. The results showed an increase in the value of proteins, minerals, ash, lipids, and fiber; however, there was a decrease in the value of carbohydrates. There were no sensory differences with the control when incorporating 5% of Moringa oleifera seed flour. 59) Snack.
