College of Engineering News

Cheese manufacturing is under attack by a type of virus called bacteriophages. The viruses infect bacteria used in the dairy fermentation process that yields our beloved cheese and yoghurt. Utah State’s 2015 International Genetically Engineered Machines, or iGEM, team has been researching ways to fight back against the virus. The iGEM event is a competition that promotes student involvement in real world synthetic biology research.

Makara Journal of Technology

The objectives of this research are to study the effects of different types of milk and enzymes toward the yield and quality (moisture, ash, protein, fat content, and texture) of cheddar cheese and the interaction between those two variables during the process. The types of milk are cow, goat, and soya milk, while the types of enzymes are rennet, papain, and bromelain enzymes. Regarding the procedure, the milk is first pasteurized before CaCl2 and Lactobacillus lactis that acts as the acidifier starter as much as 0.2% (w/v) and 0.5% of the milk volume are added respectively. The amount of enzyme …
