At day 20 and day 30 only the treatments
25CHeTPP and 50CHeTPP were significantly (P < 0.05) lower in
APCs compared to the rest of the treatments. It has been reported
that after 9 days of storage, the mesophilic and psychrotrophic
counts (aerobic plate counts) in samples treated with 1 (g/100 mL)
chitosan were reduced by approximately 2 log units and 1 log unit,
respectively, compared to control samples (Tsai, Su, Chen, & Pan,
2002).
