Abstract

The objective of this project was to reduce the final ash content of sweet whey powder. The data for this project was collected over a two-week period, from July 13th to July 27th 2010 in a dairy plant in the Mid-West of the United States. The data is composed of particle size test, ash test, and pH test. The conclusions of this study are that multiple pre-heat treatment tank changes contribute to mineral content by requiring more buffering than usual. The low pH of this pre-heat liquid forces a need for more buffering. Particle segregation may play a role in increasing the final mineral content, however more analysis needs to be done to determine the extent of this contribution. Finally, the increase in ash content may be due to seasonal variations in the cows environment and feed composition.
