Modified Natural Materials for Rendering Applications

This project continued our prolonged efforts toward the development of new functional materials for technologies to reduce odor emissions from the rendering industry. In the beginning of our work with FPRF, the main target of this work was to develop engineered, biodegradable poly(lactic acid) (i.e. PLA) nanomaterials whose surface could be decorated with appropriate reactive sites (i.e. functional groups) that would, in turn, capture or destroy malodorous volatile organic byproducts of rendering processes.

Livestock Feed Preservatives Based on Antioxidant Enzymes Extracted from Animal Blood

Autooxidation of unsaturated fats is one of the primary mechanisms of quality deterioration in animal feeds and pet food. These alterations in quality are manifested through adverse changes in flavor, color, texture, and nutritive value and there is some concern that toxic compounds are produced during the deterioration process.
