Sweetener Artificial sweeteners fall into two categories. The bulk sweeteners, such as mannitol, sorbitol, xylitol and hydrogenated glucose syrup, have approximately the same calorific value as sugar and replace it in many processed foods, but they are not so readily absorbed.
Higher heating value. The quantity known as higher heating value (HHV) (or gross energy or upper heating value or gross calorific value (GCV) or higher calorific value (HCV)) is determined by bringing all the products of combustion back to the original pre-combustion temperature, and in particular condensing any vapor produced.
Energy content or calorific value is the same as the heat of combustion, and can be calculated from thermodynamical values, or measured in a suitable apparatus:. A known amount of the fuel is burned at constant pressure and under standard conditions (0°C and 1 bar) and the heat released is captured in a known mass of water in a calorimeter.
