| Abstract | ||||
| The present work introduces whole whey as a new in bulk additive during papermaking and paper coating processes. In bulk Addition of whole whey to pulp during papermaking, as well as, paper coating with whole whey both succeeded in promoting strength of paper and decreasing its water vapor permeability in comparison to paper, which did not involve whole whey as an additive. Previous studies, by the authors and others, have shown that each of the three major components of dairy products, as an isolate, improves paper properties (protein isolates, sugars, and fat isolates). Whey is a dairy Industry byproduct -involving these three non-isolated components. Whole whey -including the three non-isolated previous mentioned components- has not been evaluated for papermaking. Using whole whey for paper improvement is more money, time, and energy saving compared to separating each component and using it alone as isolate. Moreover, such approach avoids the use of chemicals and processes required for isolation of the previous mentioned dairy components. This would increase the sustainability of both milk and paper industries by finding new uses for dairy industry byproducts and improving paper properties through natural environmentally safe additives in contrast to synthetic additives. | ||||
