2.6 Preservatives
The shelf life of raw noodle could be prolonged
by inhibiting growth of micro-organisms with the
inclusion of alcohol in the formulation [42, 44].
Usually, the noodles are immersed in dilute solution
of organic acids prior to packaging. Steamed and
deep-fried instant noodles have comparatively
higher fat concentration (> 15%), hence there is
greater chances of oxidative rancidity. The use of
antioxidants such as butylated hydroxy-anisole
(BHA), tertiary-butylhydroquinone (TBHQ),
butylated hydroxytoluene (BHT) and propyl gallate
are commonly used to avoid oxidative rancidity.
Among these, TBHQ greatly reduced the oxidation
process [1, 31].
