| titleOfInvention | A kind of detection method of trans-oleic acid content for edible oil production |
| abstract | The invention discloses a method for detecting the content of trans-oleic acid for edible oil production. Take 100 mg of edible oil, put it in a 50 ml reflux bottle, add 4 ml of 0.5 mol/L potassium hydroxide methanol solution, and heat and reflux in a water bath until the oil droplets disappear. , let cool, add 5 ml of 14% boron trifluoride methanol solution, then heat and reflux in a water bath for 5 minutes, let cool, add 2 ml of isooctane, continue to heat and reflux in a water bath for 1 minute, let cool, add saturated sodium chloride 10ml, shake well, let stand for stratification, take the upper layer liquid, dry it over anhydrous sodium sulfate, as the test solution, take methyl oleate 10mg, trans-methyl oleate 10mg, methyl linoleate cis 25 mg of mixed solution of trans-isomer and 25 mg of mixed solution of cis-trans isomer of methyl linolenic acid, accurately weighed, placed in a 10-ml volumetric flask, dissolved in isooctane and diluted to the mark to make about methyl oleate per 1 ml Ester 1mg, methyl trans-oleate 1mg. The method for detecting the content of trans-oleic acid for edible oil production according to the invention belongs to the field of edible oil production and detection, and can quickly detect the content of trans-oleic acid. |
