ABSTRACT

Indigenous fermented foods are typically unique and their quality characteristics vary according to the regions they are produced. ese are important components of the diets in South Asian countries (Lazos et al., 1993) and provide diversity of avors, aromas, and textures which help to enrich the diet (Ijabadeniyi, 2007; Joshi, 2006a; Joshi and Singh, 2012; Steinkraus, 1997), as discussed earlier also. ese foods are produced by local people who have acquired these skills and continue to produce these products at a small scale and household levels and have remained un-commercialized for several reasons (Arogba et al., 1995), including very short shelf-life, objectionable packaging materials, stickiness, and, sometimes, characteristic putrid or oensive odors. Besides, many small-scale processors of locally fermented foods
