Dadih (Indonesian: Dadih,), a traditional fermented milk popular among people of West Sumatra, Indonesia, and Malaysia is made by pouring fresh, raw, unheated, buffalo milk into a bamboo tube capped with a banana leaf and allowing it to ferment spontaneously at room temperature for two days.
The milk is fermented by indigenous lactic bacteria found in the buffalo milk. Its natural fermentation provides different strains of lactic acid bacteria involved in each fermentation. The natural, indigenous, lactic acid bacteria found in dadih could be derived from the bamboo tubes, buffalo milk, or banana leaves.
Dadih is usually eaten for breakfast, mixed together with ampiang (traditional glutinous rice krispies) and palm sugar. Dadih can also be eaten with hot rice and sambal.
Some studies on the probiotic properties of indigenous strains isolated from dadih were found to exhibit antimutagenic and antipathogenic properties, as well as acid and bile tolerance. Natural, wild strains isolated from dadih show inhibitory, competitive, and displacing properties against pathogens, and they are promising candidates for future probiotics. Lactobacillus plantarum strains from dadih play important roles in removing microcystin-LR, cyanobacterial toxin. This wild strain of Lactobacillus plantarum from dadih has the highest removal abilities when compared to other commercial probiotic strains. This finding offers new and economical tools for decontaminating microcystin containing water.
