Tag: D allulose

With only 0.2 to 0.4 calories per gram, allulose is a non-metabolized sugar gaining popularity for keto and diabetic diets. It is not uncommon to see it labeled as either "allulose" or "d-allulose," leading many to wonder: are allulose and d-allulose the same thing? The simple answer is yes, with the "D-" prefix clarifying its specific molecular form.

While found naturally in trace amounts in fruits like figs and raisins, commercial allulose is produced via enzymatic conversion from corn starch or sugar beets for mass production. This industrial process, along with factors like purity and form, means not all allulose is the same when you buy it.

According to the International Society of Rare Sugars (ISRS), the vast majority of possible monosaccharide isomers are considered rare, existing only in limited quantities in nature. These least common monosaccharides, also known as rare sugars, possess unique physical and biological properties that set them apart from their more abundant counterparts like glucose and fructose.
