Tables 2 and 3 depicts changes in the TVC and LAB
counts in the vacuum-packed cold smoked salmon after pressure
treatment and during storage at 5.5 C. The LAB count was considerably
higher than TVC or log 5.5 compared to log 3.7 in untreated
samples indicating that by using LH at 15 C some LAB cannot grow
(Table 2).Unfortunately the LABwere not identified downto species.
At day 5 the TVC count was 0.2–1.2 log lower in samples treated at
500 MPa compared to untreated samples (Table 2). During the
storage the number increased steadily and after the 41 days storage
about 0.8–2.7 log increases were observed. The number of LAB
reduced significantly (p< 0.05) compared to untreated samples but
during storage 4–6 log increasewas observed indicating that the LAB
