Glenn Roy began training in the science of flavors and fragrances in 1971 with Tombarel Freres in Grasse, France. As a field laborer, he harvested raw plant materials and processed them to produce essential oils and absolutes. Additional perfumery was studied at Givaudan Corp and Roure, Bertrand, Dupont, Inc, which are both in NJ.
In 1975 he graduated with a B.S. in chemistry from St. Michael's College in Winooski, VT. There he researched and published a new method for the purification of 1,8-cineole from its undesirable 1, 4-isomer. A M.S. (1977). His Ph.D. (1980) degree in Organic Chemistry resulted from graduate studies at The Ohio State University. His discovery of new organosilicon methodology was illustrated in the syntheses of Frontalin, a beetle pheromone and Latia Lucifern, a firefly luminescence principle. The organosilicon reagent is now commercially available.
In 1980 Glenn entered the food industry as his chosen career. Six years of research were conducted in flavor generation, high potency sweeteners and taste modifiers at General Foods (NY). In 1986 a wonderful opportunity arose to pursue research at The Nutrasweet Co. (IL) in the area of non-fermentable, non-caloric sugar and fat macronutrient substitutes. Additional research in taste modification resulted in the discovery of bitterness inhibitors.
The impending break-up of The Nutrasweet Co. R&D after four years prompted a move in 1990 to a managerial position in Food Processing Technical Services with Calgon Carbon Corp. in PA. In November 1994, the corporate downsizing of Calgon forced unemployment again and in April 1995 he joined Pepsi-Cola (NY) in Product Development of Functional Beverages. He is now a Research Fellow Pepsi-Cola (NY).
Glenn has written two books published by Technomic Publishing Co. in Lancaster, PA now owned by CRC Press, Inc. Boca Raton FL.:
- Activated Carbon Applications in the Food and Pharmaceutical Industry
- Modifying Bitterness Mechanism, Ingredients and Applications
At NERM2008 Glenn Roy will be presenting: The electronic tongue applied to bitterness inhibition of acesulfame and saccharin
