Lecithins dispersion test

Dispersion test. Hydration speed of lecithin in water. Standard Uquid lecithins disperse slowly if stirred manually or by a mixer with low-energy input. One may observe different hydration speeds between natural lecithins from various oil mills, due to different production conditions. Modified lecithins usually show fast dispersibility, an indication of stronger surfactant performance. Hydration of lecithin in distilled water is faster than in tap water with a high degree of water hardness. 

A recent method that s still under development is to take vitamin lecithin. This vitamin breaks down your stored fat and disperses it into your blood stream, to help clean out drugs that store themselves in lipid tissue, such as THC. NORML recommends taking Lecithin right up to the day of the test. To me it sounds as though this would work against you because by putting THC back in your blood stream, you are increasing metabolites in the urine. 

Antioxidants are tested for purity by melting point and TLC on heat-activated silica using solvent systems 1) chloroform, 2) chloroform/methanol, 19/1, 3) chloroform/methanol/acetic acid, 19/1/0.1. Antioxidants are added at 0.1% by weight of dispersed lipid. In a typical test, 50 ml of the lecithin microdispersion... 

Sample preparation followed the method described by Ryoto (13). One gram SPE or dry deoiled lecithin was dissolved in 100 g of oil and heated to 60-80°C for complete dispersion of the emulsifier. Ethanol-insoluble lecithin was added at a level of 1 mg/100 g oil and any residual to the ethanol was removed by heating a water bath. Samples with 0.5 and 0.25% SPE or dry lecithin were prepared by diluting the original sample with oil. Deoiling and fractionation of lecithin were done with acetone and ethanol, respectively, as reported by Ziegelitz (15). Turbidity test was conducted on 70 mL oil in a 100-mL tube at different concentrations of DK F-10 (0.0,0.5, and 1.0%) at several temperatures.
