© PureCircle Limited 2013Beverage Applications
• Acid and temperature stability
• Sweetness and flavour quality stable through shelf life
• Achieving desired sweetness levels with Reb A alone may be difficult in
some beverages
• The use of Alpha allows for greater sugar reductions with cleaner taste
• Blending small amounts of caloric or non-caloric sweetener provides
improved sweetness profiles
• Stevia shows excellent synergy with fructose, sugar and several polyols
• Acid blends (e.g. citric acid + malic acid or lactic) can contribute to a
better sweetness and flavour profile
• Salts can help achieve improved flavour profile (Na salts)
• Blending stevia sweeteners enables better preservation of flavours and
acids, and creates more sugar-like profiles
