Shelf-life studies
Shelf-life studies carried out for high protein,
sugar-free cookies in respect of peroxide value and
acid value is shown in Table 4. It can be seen from
Table 4, both the peroxide and acid values after 2
months of storage is higher than after only 1 month
of storage. However, the cookies are stable as the
peroxide value is less than 10 meq/kg (permissible
limit for peroxide value is 10 meq/kg) and acid value
is also less than 1.2. As per the BIS specification, the
acidity of the extracted fat (% by mass), maximum
limit for cookies is 1.2. Our findings were in
accordance with the studies of Honda et al. (2012).
