Rendering industry

Animal by-products in the rendering industry

In rendering, inedible animal tissues and by-products are converted into stable, usable materials. This significantly increases the degree of utilisation of carcasses and thus conserves resources. There are significant risks to consider when handling raw materials such as viscera and offal used in the rendering process. Delays in processing can have unintended effects on the oxidative and microbial quality of fat and proteins.

Natural support for long-term freshness

Since the trend in the pet food industry has been moving towards naturalness for quite some time and the rendering industry is an important upstream supplier, the trend here is also following the same direction.

Loxidan products by Kaesler Nutrition are highly effective antioxidant blends that can slow down oxidative and microbial spoilage, depending on the requirements. Different antioxidant blends are available for specific purposes. Some of the blends are particularly suitable for protecting nutrients during high-temperature processes while others are targeted at providing good storage stability.

It is important to add antioxidants as early as possible in the production procedure when processing animal by-products in order to ensure to gain fats of particularly high quality for the pet food industry. Oxidation is irreversible, meaning once the damage has been done, it cannot be reversed.
