ABSTRACT
shops and organised sectors, were collected aseptically and subjected to estimation of total
count, coliform count and psychrotrophic count to determine the microbiological quality of
kulfi sold in Chennai. The level of psychrotrophic count was found to be more in road side local
vendor samples (1.8 x 103 cfu/g) followed by that of samples of small scale producers (1.01 x
103 cfu / g) and branded samples from organised sector (3.5 x 102 cfu / g). Road side local
vendor samples contributed 56.90 % of organisms to the psychrotrophic count, followed by
small scale producers (32.03 %), while organised sector contributed the least (11.07 %).
Pseudomonas fluorescens was found to have greater proteolytic and lipolytic effect when
compared with the activity of Pseudomonas aeruginosa and Pseudomonas putrifaciens. The mean
total count and coliform count were found to be maximum in road side local vendor samples
followed by samples of small scale producers The microbial quality of most of the kulfi samples
needs to be improved in order to avoid any food poisoning and to safeguard the health of the
consumers.
