Research and Development Unit was established, in 1983, for undertaking
research on developing new products for the Royal Chitralada Projects. The unit
also investigates the benefits of utilising agricultural wastes as raw materials for
various products. Examples are research on producing pasteurised fruit juice,
cannery fruit juice, dried fruits, processed fruits, spilurina crackers, granule instant
drinks, cannery rice porridge, organic fertiliser and scented candles.
