Abstract
In recent years due to changes in lifestyle, beverages are not only considered
as thirst quenchers, but also potential functional foods. Functional beverages are
exceptional medium for the supplementation of nutraceutical components such as
immunoglobulins, growth factors through fortification, which in turn provide
necessary nutrients to prevent nutrition related diseases, beyond taste. Colostrum is
the first mammary secretion obtained from mammary gland for upto 24 to 48 hours
after parturition. It plays a significant role in curing autoimmune diseases, improves
gut health, builds lean muscle mass and boosts immunological function.
Commercial processing of bovine colostrum is hampered due to its irregular
availability, perishability, heat sensitivity and lack of preservation technology. Thus,
the present study was carried out to develop a functional bovine colostrum beverage
powder with prolonged shelf life without altering its nutritional and
immunoprophylactic properties. Bovine colostrum samples were collected on the 1st
and2nd day after parturition and assessed for the quality using colostrometer.
The samples were stored at - 20°C in deep freezer. Chemical composition and
physico-chemical properties such as fat, protein, lactose, ash, moisture, pH and
titratable acidity were analysed for the collected skimmed bovine colostrum sample.
Beverage powder was formulated using skimmed bovine colostrum (P‘ and 2’“’ day),
beetroot and banana. The inclusion levels of raw materials were standardized using
conjoint analysis. The results suggested that the ratio of 1:1:1, l:0.5;1.5 and
1:0.5:0.5, 1:0.5:0.5 for the development of and 2"'’ day cow and buffalo colostrum
beverage respectively. Response surface methodology (RSM) was utilized to
optimize the spray drying process parameters viz. inlet air temperature and feed flow
rate for the development of functional bovine colostrum beverage powder. The
optimum conditions were found as 180°C inlet air temperature and 200 ml/h feed
flow rate at which the spray dried powder had better physical properties.
