Butter is an important dairy product of Pakistan. It is widely used
by the bakery, chocolate and confectionary industries and the
people used it as spread on bread and in cooking. Presently in
Pakistan its production rate is very high but it is not exported
due to its poor quality. So, there is a requirement to enhance the
quality of butter. Different treatments had been employed to
enhance the quality of butter manufactured by the sweet creams.
Present work was undertaken to study the effect of 3 treatments of
cream fat percentages and 3 different churning temperatures on
butter quality. In this study different combinations of different
cream fat percentages and different cream feed temperatures had
been studied. This work was helpful to develop better quality
butter at cottage scale.
Dahi is the most popular fermented dairy product of Indo-Pak
Subcontinent. It contains a variety of fermenting microorganisms
particularly belong to genera of Lactic Acid Bacteria. A lot of
research work has been carried out on the isolation of bacteriocin
producing strains of Lactic Acid Bacteria from Dahi particularly
Lactococcus spp., Lactobacillus spp., Streptococcus spp. etc.
However no work has been done regarding isolation and
characterization of bacteriocin producing strains of E. faecium
from indigenous dahi in Pakistan. Bacteriocin producing strain of
E. faecium is first time isolated from dahi in Pakistan. It has
been found that the enterocin AJ01 is a stable bacteriocin produced
by E. faecium AJ01. It shows good anti-bacterial activity against
pathogenic bacteria. It has the potential to be used as natural
preservative in food products. This information may be helpful for
the biotechnologists and microbiologists for carrying out further
research work on the isolation and characterization of E. faecium
strains from different indigenous dairy products.
