Weighting agents in cloudy soft drinks |
G. MERKT, Nutrinova Inc., 285 Davidson Ave., Ste. 102, Somerset, NJ 08873 Cloudy appearance is important citrus soft drink property (orange, lime, lemon, etc.), since it gives natural fruit juice appeal. Clouding agents achieve this, which also help in uniform distribution of flavors throughout liquid beverage. Cloud effect is due to interaction and diffusion of light by suspended fine particles. Emulsified essential oils and oleoresins possess valuable clouding and flavoring benefits to soft drinks. Due to flavoring oils (0.8 to 0.9 g/ml) and finished beverage (1.00 to 1.03 g/ml) incompatible specific gravities, emulsified oil rises to drink surface and forms unsightly ring at neck of bottle. One emulsion stabilizing method is adjust the flavor oil’s specific gravity by addition of bland high specific gravity substances miscible with flavor oils. Density-adjusting agents are lipophilic compounds with specific gravity higher than 1 g/ml - SAIB, ester gum and BVO are most widely approved, common agents. Brominated vegetable oils (BVOs) have perceived health risk disadvantage of using brominated compounds in foods. Ester gum is solid, difficult to dissolve, has distinctive rosin-like taste and is prone to oxidative instability. In contrast, SAIB or sucrose acetate isobutyrate, which was recently approved in U.S.A. (1999) and EU (1997), has lower cloudiness effect in emulsions and rather high viscosity (difficult to work with.) BalancePlusTM is result of improving SAIB to provide better features in product handling and superior clouding effects in products. BalancePlusTM is liquid at room temperature and doesn’t need any specific equipment, time resources in and avoids the complexity of dissolving process and quality risk of treated material. This makes application specific, tailor-made solutions conceivable since BalancePlusTM is oxidative stable and has no distinctive color or flavor that might impair the finished product during its shelf life.
