Acesulfame K 23<br />

were preferred over aspartame-sweetened colas throughout an 18-week storage<br />

period (34). Because the cola with the sweetener blend exhibited greater sweetness<br />

retention as a result of the stability of acesulfame, the preference was attributed<br />

to this.<br />

When blending acesulfame K with other intense sweeteners for beverage<br />

applications, the blend ratio may depend on different factors, including the flavor<br />

or flavor type. Blends of acesulfame K and aspartame (40:60) in orange-flavored<br />

beverages have been noted to have time intensity curves of sweetness and fruitiness<br />

similar to sucrose-sweetened beverages (35). In raspberry-flavored beverages<br />

containing natural flavors, 40/60 to 25/75 (acesulfame K/aspartame) blend<br />

ratios are considered optimum, whereas beverages with artificial raspberry flavors<br />

were considered optimum with blend ratios of 50/50 to 20/80 (36). Optimum<br />

taste profiles when using intense sweeteners are considered to have high fruit<br />

flavor and minimum side tastes or aftertastes, and sweetener mixtures containing<br />

acesulfame K exhibit these properties (18). When only single sweeteners are substituted<br />

for sucrose in beverages, flavor problems are encountered, and it has been<br />

noted that mixtures of sweeteners can minimize these flavor problems (37). Most<br />

notable are mixtures including acesulfame K, which produce taste profiles similar<br />

to sucrose (18). Optimum blend ratios complement the taste profile of the specific<br />

flavor of beverage and are best determined by sensory testing various blends.<br />

Emerging trends in beverages include replacement of sugar in fully sugared<br />

beverages with intense sweeteners like acesulfame K. In regions of the world<br />

where sugar is expensive or has inconsistent quality, intense sweeteners are used<br />

in combination with sucrose to sweeten many different beverages. Stability in<br />

warm climates for longer storage conditions and stability at low pH are necessary<br />

for sweeteners that can replace sugar. Acesulfame K exhibits excellent properties<br />

for use in this type of application.<br />

Producing jams and marmalades with intense sweeteners only is difficult.<br />

Bulking agents are important to improve the texture and shelf-life of such products.<br />

In trials for the production of jams with acesulfame K, highly acceptable<br />

preparations were prepared with sorbitol as bulking material. Other sugar alcohols<br />

and polydextrose proved to be suitable, too. In combinations with acesulfame<br />

K, the concentration of sorbitol or other bulking agents can be reduced, yielding<br />

products with a noticeable reduction in caloric values compared with to sucrosecontaining<br />

products. These jams and marmalades are less protected from microbial<br />

spoilage compared with sucrose-containing products. In view of the low<br />

concentration of osmotically active compounds, the addition of preservatives can<br />

help to avoid such microbial spoilage. The flavor stability of jams and marmalades<br />

containing low levels of dry solids, however, is normally lower than the<br />

storage stability of standard products (20).<br />

Confectionery items can be made with acesulfame K if suitable bulking<br />

ingredients or bulk sweeteners are added to give the necessary volume. Because
