Abstract
Five test organisms were used:
Escherichia coli, Salmonella typhosa, Salmonella schottmuelleri, Salmonella enteritidis
, and
Shigella paradysenteriae
. Even when large inocula of these test cultures were introduced into fresh passionfruit nectar base, all test organisms were killed within 1 to 2 hr, provided the nectar base was held at room temperature for more than 1 hr before freezing. If the nectar base was frozen immediately after inoculation, four of the five test organisms were eliminated almost as quickly. But the fifth,
Salmonella enteritidis
, proved to be exceptional: it was being recovered after 90 days of storage at -20 C, when the last available sample was analyzed.
