Started off researching on properties that spark off these “keep awake” effect found in sweets. There is no trace of Caffeine/Taurine found in Energy Bars high in sugar content to actually stimulate the brain cell to keep people awake. In these sweets, it is the sour avouring or a sensational burning effect on the tongue or in the mouth for a short period of time. As expected, these sweets mainly contains several consumable weak acids to create and generate these "irritation" effect.
