PEMANFAATAN KITIN I KITOSAN SEBAGAI BAHAN ANTI MIKROBA
Abstract: Chitin is a natural
polymer which consists in the living thing such as shrimp, crabs, lobsters,
yeast, insect and fungi. Chitin is usually produced from shellfish such as
shrimp shell, crabs, lobsters. They are demineralization of crustacean using
strong acid OT base. Deacetilization of chitin using strong base and heating
gave chitosan. Chitosan has many application such as food preservation, anti
microbial, water treatment, anti oxidation, and fat absorption. Anti microbial
products such as sport dressing, hand globt; linen, and anti virus and
antracnose of red chili pepper. Anti bacterial of chitosan come from the amine
functional group, that strong positive charge. Membrane of cell has negative
charge. Interaction between positive and negative charge resulted membrane
permeable suffer osmotic pressure which affect to the equilibrium inside the
cell, it may cause the inhibition the growth of the microorganisms. There is
also hydrolysis occurs to the cellwall that may cause the leak of electrolyte
from the cell, it may cause the cell becomedead.
