4. Conclusions
Based on the present study findings, it appears the salted solar
drying technique was more favorable than freeze drying for preparation
of Jameed in terms of product yield. On the other hand,
salted freeze dried Jameed showed better product characteristics
in terms of color appearance. Although solar dried unsalted
Jameed showed the highest protein content and lowest total fat
content, the saturated and unsaturated fatty acid profiles of
unsalted solar dried and freeze dried Jameed were less favorable
than the salted versions. Solar dried salted Jameed was also associated
with significantly higher antioxidant and ACE inhibitory activities
than the unsalted version of solar dried Jameed. Overall, these
study results indicate better nutritional and biofunctional properties
were associated with solar dried salted Jameed. These findings
also illustrate the need for the testing of multiple nutritional and
biofunctional properties of fermented dairy products in order to
characterize the most favorable nutritional characteristics
