Embodiment 1

[0065] Precisely weigh 0.25g to 0.30g (accurate to 0.0001g) of monomenthyl succinate, dissolve it in 50ml of absolute ethanol, use 1% phenolphthalein as indicator, and titrate with sodium methoxide standard titration solution to reddish as the end point. For blank test, record the volume consumed by sodium methoxide standard titration solution, calculate the content of monomenthyl succinate according to the following formula, and the average value through six measurements is 99.35%.

[0066] X = C × ( V - V 0 ) × 256.34 1000 × m × 100 ( % ) ;

Abstract

The invention discloses a method for determination of monomenthyl succinate content. The method comprises accurately weighing 0.25-0.30g of monomenthyl succinate, dissolving the monomenthyl succinate in 50ml of ethanol, carrying out titration by a phenolphtalein indicator with a concentration of 10g/L and a sodium methoxide titrand until the solution has a reddish color, simultaneously, carrying out a blank test, recording a consumption volume of the sodium methoxide titrand and calculating monomenthyl succinate content. In respects of titration solvent selection, titration end point determination and moisture influence, the novel method for determination of monomenthyl succinate content by nonaqueous titration is designed. Compared with the potentiometry and gas chromatographic method, the nonaqueous titration indicator method has result difference of 5% and has no significant difference and thus the method is feasible, has the characteristics of low cost and short time consumption and is conducive to promotion and application.

Description

technical field [0001] The invention relates to the field of food analysis, in particular to a method for determining the content of monomenthyl succinate. Background technique [0002] The structural formula of Momo-menthylsuccinate is It is a white crystalline solid, insoluble in water, soluble in organic solvents such as ethanol. It is a synthetic spice for food that is allowed to be used in my country. Because of its pure, long-lasting and efficient cooling effect and safe use, it is used in food, daily necessities, and medicine It is widely used in the tobacco and tobacco industries, and it can be used in an appropriate amount according to production needs in foods that require a long-lasting cool taste to improve and enhance the flavor of the food. At present, the synthetic research of monomenthyl succinate has been reported at home and abroad, and high performance liquid chromatography (High Performance Liquid Chromatography, HPLC for short) or liquid chromatography ...
