Based on the fact that occurred
in processing industry food and fruits, then it should be found a proper way in
order for the processing of food and fruits can produce a quality product with
high nutritional value and quality have a save the old one without the use of
formalin or preservatives with chemicals that are not dangerous, one of them
namely chitosan from snail Achatina
fulica. Chitosan from snail Achatina
fulica is a product derived from the chitin polymer that is a by product or
waste from the processing of the fishing industry, potentially very chitosan
from snail Achatina fulica to serve
as the ingredient antimicrobial and as a preservative in food and fruit,
because it contains the enzyme lysozim and aminopolysacharida cluster (-NH3)
which is able to inhibit the growth of microbes. Ability to suppress the growth
of bacteria due to the chitosan has polikation. Positively charged polikation
that is able to inhibition the growth of bacteria, in addition chitosan also
acts as a natural preservative that can overlay (edible coating) made of
various materials including polysaccharides, proteins and lipids that can
improve the quality and extend the save, so it slows down oxidation and keeping
the humidity that scientifically proven snail shell Chitosan can be solve the
problem to serve as natural preservatives of fruit and food.
