Flavor development in ripening Cheddar cheese depends on complex microbial and biochemical processes that are difficult to study in natural cheese. Thus, our group has developed Cheddar cheese extract (CCE) as a model system to study these processes. In previous work, we found that CCE supported growth of Lactobacillus casei, one of the most prominent nonstarter lactic acid bacteria (NSLAB) species found in ripening Cheddar cheese, to a final cell density of 108 cfu/mL at 37°C. However, when similar growth experiments were performed at 8°C in CCE derived from 4-mo-old cheese (4mCCE), the final cell densities obtained were only about …

The broad ecological distribution of L. casei makes it an insightful subject for research on genome evolution and lifestyle adaptation. To explore evolutionary mechanisms that determine genomic diversity of L. casei, we performed comparative analysis of 17 L. casei genomes representing strains collected from dairy, plant, and human sources. Results Differences in L. casei genome inventory revealed an open pan-genome comprised of 1,715 core and 4,220 accessory genes. Extrapolation of pan-genome data indicates L. casei has a supragenome approximately 3.2 times larger than the average genome of individual strains. Evidence suggests horizontal gene transfer from other bacterial species, particularly lactobacilli, …

Effect Of Emulsifiers On Shortenings, Silvana Martini, Maria Lidia Herrera
Nutrition, Dietetics, and Food Sciences Faculty Publications
The quality of a shortening depends on its physicochemical characteristics. These include amount of solids, texture and melting behavior, among others. The type of shortening, the processing and storage conditions strongly affect these characteristics. Different strategies can be used to formulate shortenings with low trans fatty acids content while maintaining their physicochemical characteristics. This article describes some of these strategies and aims to provide information about the different variables that need to be controlled to obtain a high quality shortening.
