The samples were procured from street food vendors located at six different areas of Jaipur city. Twelve samples of each were collected aseptically and were assessed for organoleptic characteristics, nutritional quality and microbial quality. All the samples analyzed possessed good sensory quality and were found to be nutritionally adequate but the microbial quality was reported to be very poor, all samples were heavily contaminated by bacteria's.
