Question:
Do preservatives affect the speed at with mold grows?
Preservatives
in food are made to kill bacteria and enzymes that cause the food to
go bad, and mold. There are generally 3 types of
preservatives,antimicrobials which prevent the growth of
mold,bacteria,and yeast.Then, there are antioxidants that prevents
the food from “rancidity.” And the last preservative type fights
enzymes that cause the fruit to ripen after being picked.
Sulfites,
these preservatives prevent the growth of certain microorganisms that
disturb the growth process of a cell. Propionates are antimicrobials
and are used to keep baked goods fresh.(According to Hassan Gourama
Ph.D associate professor of food science at PSU.) Propionic acid
grows naturally in some fruits,but is essentially used to keep bread
from going bad, and stop mold from invading cells.
I
believe that preservatives do affect the speed at which mold
grows.Food without
preservatives
will mold more quickly.
