Microbial count-time interval
Microbial count of the juice rises with time. In some cases it was increasing rapidly such as in
the case of room temperature and preservative storage but in some other cases it was slowly
increasing such as in refrigerated storage. From
Figure 2 and Figure 4 it is evident that the juice
with microbial count at 80ºC and 85ºC respectively, when preserved at room temperature the
count was increasing but in the case of refriger
ated temperature it was slowly increasing. In
Figure 6 the juice with microbial count at 90ºC preserved at room temperature was found to be
slightly increasing and that of the refrigerated
sample was not changing and it was 1/10 times
lesser than 80ºC and 85ºC. Figure 8 shows that the
juice stored with preservative at 1000 ppm, a
favourable curve and better storage quality was obtained.
