VANILLIN PRODUCTION grades

The particle size distribution of Rhovanil Extra Pure vanillin shows a less narrow profile than other standard mesh grades available on the market. The product shows an improved mixabiUty in blending operations, allowing shorter blending time of compounds or food mixes, and better homogeneity of vanillin content, especially in low content vanillin blends. 

Pharmaceutical Products. Rhc ne-Poulenc offers a flaked technical-grade vanillin, Vaniltek, to be used in pharmaceutical appHcations. The single largest use for vanillin is as a starting material for the manufacture of an antihypertensive dmg having the chemical name of Methyldopa or L-3-(3,4-dihydroxyphenyl)-2-methylalanine. 

For the production of vanilla extract ethanol (min. 35%) is used. In the USA I 1 alcohol is used to extract 100 g beans for the I-fold quality. For a 10-fold quality the same amount of ethanol is used to extract 1 kg of beans. In Europe the ethanol extract frequently is concentrated to yield a dark, viscous extract or oleoresin, wherein, among others, the vanillin content determines the grade of quality.
