As global demand for sustainable sources of animal feed and food continues to grow, the rendering industry has a pivotal part to play in the supply chain. In particular, meat and bone meal for feed and tallow for food and industry are the two highly popular outputs from the rendering process. At the same time, the recycling aspect of rendering has a positive sustainability angle, for example, by squeezing the last drops from resources and reducing the release of carbon dioxide from carcass disposal.
Nonetheless, challenges to efficiency and profit in rendering remain. Accurate measurement of protein with meat and bone meal analysis is essential. Similarly, parameters such as fat, moisture and ash are important for ensuring an optimal production process and for product declaration purposes according to strict industry regulation. The rendering process involves high temperature and the process is heavy on resources. Once started, the process is not easy to adjust, but for producers who need to meet specific targets in their final product, agility in the production line is a necessity.
Rapid meat and bone meal analysis of rendered meat for parameters such as fat, moisture, ash and protein enables fast adjustment of the production process. Tests can be performed during processing and on the finished meal products. Advantages include ensuring that the right protein content is reached in the final blend of meal, higher yield in processing and improved brand recognition leading to more sales from improved final product quality and consistency.
