The Dum Messa ensured food security for the ancient people. They stored and preserved the excess produce during the seasons which they are harvested profusely and used at later times when the shortage of food arises. The ancient people also preserved fish and meat by drying them using Dum Messa. Although the storing capacity of the Dum Messa is limited, it was sufficient to serve the day-to-day food preserving needs of the ancient unsophisticated people.
Apart from Dum Messa, other Messa (trellises) can also be seen at a traditional kitchen such as Dara Messa, Kala Messa and Valan Messa. A Dara Messa is set up for storing firewood while cooking utensils are stored in the Valan Messa. A Kala Messa is set up to place drinking water pots.
A Dum Messa is used for drying edibles such as meat, fish, spices and yams and is set up right above the hearth in the kitchen.The heat and the smoke emitted from the hearth beneath the Dum Messa facilitate the preservation of food.
