Subject - Canning with artificial sweetners
QUESTION - Can artificial sweeteners be used when canning fruits?ANSWER - In general, non-nutritive (artificial) sweeteners are not recommended for canning. Aspartame containing sweetners such as Equal or NutraSweet degrade with heat and lose their sweetening power. Saccharine-based sweeteners such as Sweet'N Low, Sugar Twin, or Sweet 10 become bitter when exposed to canning temperatures and should be added after the canned fruit is opened.
Sucralose or Splenda is a new artificial sweetener derived from sugar molecules and will not produce an aftertaste when heated.
