Abstract

Idli is a traditional cereal/legume-based naturally fermented steamed product with a soft and spongy texture which is highly popular and widely consumed as a snack food item in India. The predominant fermentation micro¯ora comprises lactic acid bacteria and yeasts and causes an improvement in the nutritional, textural and ¯avour characteristics of the ®nal product. The ¯avour pro®le of idli batter prepared with initial levels of 2 ´ 104 c.f.u. g)1 of Candida versatilis CFR 505 and 2 ´ 101 c.f.u. g)1 of Pediococcus pentosaceus CFR 2123 in 500 g idli batter, packed in polyester polylaminate pouches and stored at 30 � 2 °C was periodically analysed by GC-MS. The desirable ¯avour compounds such as ketones, diols and acids were found to be present upto 8 days of storage, whereas undesirable ¯avours like sulphurous and oxazolidone compounds, ethanone and thiazole appeared in the batter subsequent to 6 days of storage. The sensory attributes of idlis (®nal product) prepared from the stored batter related well to the determined ¯avour pro®le. The present study appeared to indicate that the ¯avour pro®le of traditional fermented foods can be a reliable qualitative and quantitative parameter for objective assessment.
