Low Fat Natural Cheese Strategic Platform Study. Objective 3.

Principal Investigators:  Jeffrey R. Broadbent, Utah State University

Project Summary:

There is a lack on information and scientific understanding related to the flavor defects that are
prominent in lowfat cheese. A key to understanding why flavor development in low fat cheese
is so different to that which occurs in full fat cheese (for which there is a large knowledge base
accessible by scientists and the cheese industry) is to determine the differences in microbial
populations and microbial activities between cheeses with different fat levels. This project
addresses the research target of better understanding the effects of micro-environment and
make-procedures of lowfat cheese on the microbiology and consequent flavor chemistry and
flavor sensory properties of such cheese.
