The U.S. organic dairy industry has experienced significant growth in recent years: over 10% growth annually since 2009 and 14.5% from 2010 to 2011; total market share is approximately 5% in the United States. The USDA places certain requirements on diary products that are certified organic, some of which are aimed at grazing practices. One challenge farmers must overcome to comply is keeping the cows in optimum conditions in a free-range grazing scenario; poor conditions such as excessive heat can decrease milk production and pose an economic burden on the dairy. The proposed system intends to control environmental conditions for …

Determination of the endpoint of yogurt culture fermentation is a process parameter that could benefit from automation. The feasibility of using a fluorescence sensor technology based on 280 nm excitation and 350 nm emission to predict the endpoint of yogurt culture fermentation was investigated and compared with the endpoint prediction from a near-infrared (880 nm) light backscatter sensor. Yogurt cultures with three levels of milk solids (8%, 10%, and 12%) and three temperatures (40°C, 43°C, and 46°C) were tested with three replications in a 3 x 3 factorial design (n = 27). Prediction models were developed for each optical measurement …
