Since dissolved CO2 is a natural component of freshly
drawn milk that is subsequently lost during processing and
transit, there is an ample scope for its utilization as a
simple, inexpensive technique to extend shelf life of dairy
products. This technique has already been reported for
extension of shelf life of milk (Hotchkiss and Lee 1996)
and dairy products like yoghurt (Karagul-Yuceer et al.
1999), ice cream mix (Hotchkiss and Chen 1996) and
cheese (Mann 1991). The present study pertains to
investigations on use of carbonation as a means to extend
the shelf life of a flavoured dairy drink and its effect on the
chemical and microbial quality of the beverage.
