yogurt


yogurt

Semisolid, fermented, often flavoured milk food. Yogurt is known and consumed in almost all parts of the world. It is traditionally made by adding common strains of Streptococcus and Lactobacillus bacteria to raw milk. The culture is produced by taking a portion of a previous batch. In modern commercial yogurt making, a blend of concentrated sterilized milk and milk solids is inoculated with the two bacteria; sometimes L. acidophilus or a lactose-fermenting yeast is also added. The product is then incubated four or five hours at 110–112 °F (43–44 °C) until curd forms. Various flavours and sweetening may be added.
