Specification

Mi453 is a user-friendly photometer for monitoring reducing sugars in wine analysis. It will give you direct readings in g/ L, with a range of 0.00 to 50.00 g/ L.

A reducing sugar is a type of sugar with an aldehyde group. This allows the sugar to act as a reducing agent. Reducing sugars include fructose, glucose, glyceraldehyde, lactose, arabinose and maltose.

The determination of concentration of reducing sugars is one of the most important parametres that need to be measured during the wine making process.

" Reducing Sugar is the amount of sugar, both fermentable and unfermentable, left in a wine after
fermentation is complete or permanently halted by stabilization. Fermentation is complete when
either all the fermentable sugar has been converted by the yeast into alcohol and carbon dioxide
as byproducts or when the concentration of alcohol produced reaches a level that is toxic to the
yeast and they die."

Fermentation is permanently halted by stabilization through several means involving intervention by man. The range of sugar in wine is different from variety to variety and vintage to vintage. The instrument must be used with a reactor.
