Biscuits are small baked products made principally from wheat flour, sugar and fat. It has a longer shelf life as compared to other baked cereal products if they are protected from moisture from the surrounding air.
Effects of Uncontrolled Humidity
Biscuits/ Cookies being highly hygroscopic in nature, it absorbs moisture during storage before being packed.Some of the common problems are:
- Become soggy, rubbery and lose their crispness
- Loss of appeal, taste and flavour
- Reduction in shelf life
Causes of Uncontrolled Humidity
In the biscuit manufacturing unit, the hot and fresh biscuits are cooled to ambient temperature before packing. Also, the packing rate is lower than biscuit production rate, the unpacked biscuits are shifted to a temporary store where they are exposed to the surrounding humid air.
Therefore it becomes essential that the humidity in the store-room (hot room) to be controlled to a level so that the quality of the biscuits is not spoiled.
General Recommendation
It is recommended to maintain the relative humidity (inside the temporary store ) at 30 to 35% at ambient temperature, to overcome the problem of moisture gain.
