In addition‚ the neutral lipids are more easily removed than polar lipids‚ phospholipids and free fatty acid are concentrated in the end of the product. In this case Eymard et al. did the experiment washing mince mackerel with cold distilled water three times with evaluated lipid oxidation in mince in each step (Eymard et al.‚ 2009).

Experimental Part 1: Reaction First the glassware apparatus for the reaction was set up. 3.861-grams of isoborneol‚ 2.21-mL of glacial acetic acid‚ and 4.39-mL of 6% NaOCl solution were mixed in a 125-mL Erlenmeyer flask. Another 35-mL of 6% NaOCl solution was added to a separatory funnel and supported over the flask. The NaOCl in the sep funnel was slowly added into the Erlenmeyer flask with vigorous swirling‚ approximately 2-mL every 30 seconds until all the NaOCl from the sep funnel had been

RADICAL HALOGENATION AND GAS CHROMATOGRAPHY Abstract In radical halogenations lab 1-chlorobutane and 5% sodium hypochlorite solution was mixed in a vial and put through tests to give a product that can then be analyzed using gas chromatography. This experiment was performed to show how a radical hydrogenation reaction works with alkanes. Four isomers were attained and then relative reactivity rate was calculated. 1‚1-dichlorobutane had 2.5% per Hydrogen; 1‚2-dichlorobutane had 10%; 1‚3-dichlorobutane

Different surfactants were added to the reaction cocktail. These included; an anionic surfactant (sodium dodecyl sulfate‚ SDS)‚ a cationic surfactant (cetyl pyridinum chloride‚ CPC) and non-ionic surfactant (Tween-80‚ Tween-20) and polyethylene glycol‚ PEG. 2.10.
