S ugar is one of the most important substances

for human survival. Together with fat and
protein, they are seen as the three major
nutrients for our bodies. All the carbohy-
drates except cellulose are the main source of body heat,
providing about 60%-70% of total energy that humans
need. Carbohydrate is a different name for sugar; it is
an important most-often-seen and widely distributed
organic compound. Sugars are found in various food like
grains, cereals, tubers, beans, rice and flour products,
vegetables and fruits etc..
As for gelato, sugar is another important and nec-
essary component, standing in the line with fat and skim
solids. Usually people perceive sugar as a sweetener. In
fact, in the total 35%-42% dry matter of gelato, sugar is
the one that takes the biggest share: it does not only
provide the sweet taste for gelato, but also plays a role
as solid contents to improve the chewiness of gelato and
lower the freezing point (the more sugar added or melt-
ed in cream base, the longer it takes to freeze). Moreover,
it has a function of increasing the viscosity and softness
and control ice crystal’s growing.
