According to Sid Hulse, vice president of product development at PLT Health Solutions, zümXR technology has been developed to meet a need for predictable, reproducible performance in energy profile design. “Most approaches to making modified release caffeine feature lipids and waxes that were originally focused on masking flavor and later adapted to this application. Most of the early modified release solutions were done ‘in tablet’ rather than as an ingredient matrix, which mean no powders and no beverage applications. Our testing has shown that, quite often, the extended release materials we see on the market either give up too much caffeine too quickly, or don’t give up enough caffeine at all – making it less experiential.” he said. “The zümXR approach has been developed using pharma modeling techniques for our dissolution design with USP methodologies used to measure performance. It features high quality, tightly controlled coating materials that are heat stable, which broadens the applications where these ingredients can be used,” he added.
Designing a Custom Energy Profile
zümXR Extended Release Caffeine is designed to provide long-term energy without the unpleasant effects associated with many caffeine products, according to PLT. In its specification, it delivers not more than 55% of the total caffeine at 1 hour and not less than 80% at 6 hours. The Delayed Release Caffeine delivers not more than 25% at 1 hour and over 80% at 2 hours for a surge of caffeine at a fixed time. To date, most interest in these ingredients have been centered on the concept of using them in conjunction with anhydrous immediate release caffeine in an effort to design an energy profile that closely fits with the application.
The new zümXR Liquid Stable ingredient is based on the Extended Release technology. The delivery system is a non-pH dependent, lipid-based coating. Caffeine is released through enzymatic processes. The caffeine “spheres” do not float at the top, they remain dispersed throughout liquids. PLT is marketing this ingredient into the “shot” application (from 2 oz. to 4 oz.).
