in turn, suggested that addition of chitosan to fruit juice during processing may
increase the risk of poisoning by E. coli O157:H7, via knocking out
a portion of the prevailing native yeast population. Ausar et al.
(2002) showed that the inhibiting effects of chitosan upon three
representative milk fermentation bacteria were reversed when
that biopolymer was incubated with milk prior to exposure to
those bacteria.
