Application
KERA’SOL has excellent nutritional and attractant properties allowing it to replace a part of other tasty protein sources in petfood. The wide range of smaller peptides increase the palatability and the binding properties of the pellet of the feed, so to improve the feed intake.
Its specific smell and taste is very much appreciated by dogs and other pets. 
 
Process
KERA’SOL is a premium hydrolysed keratin concentrate produced from purified chicken feathers at a ‘unique poultry’ dedicated facility in Dendermonde, Belgium, using a patented production process.

The highly soluble fraction obtained after the hydrolysation process is concentrated and spray dried, guaranteeing the overall quality and organoleptic characteristics. 

Spray-dried keratin hydrolysate refers to a specific ingredient that is used in the production of pet food. Let's break down the key components:

1. Keratin: Keratin is a protein that is abundant in many animal tissues, such as hair, feathers, and skin. It is a durable and fibrous protein that provides structural support and protection. In the context of pet food, keratin is often sourced from animal by-products, such as poultry feathers or other keratin-rich sources.

2. Hydrolysate: Hydrolysis is a process that breaks down complex molecules into smaller components by adding water. Keratin hydrolysate is created by subjecting keratin protein to hydrolysis, resulting in the breakdown of its protein structure into smaller peptides or amino acids. This hydrolysis process makes the protein more easily digestible and absorbable for pets.

3. Spray-dried: Spray drying is a common technique used in food processing to convert a liquid substance into a dry powder form. In the case of spray-dried keratin hydrolysate, the hydrolyzed keratin solution is atomized into fine droplets and then rapidly dried using hot air. This process removes the moisture from the liquid, leaving behind a powdered form of the keratin hydrolysate guaranteeing the overall quality and organoleptic characteristics of the product.

The resulting spray-dried keratin hydrolysate powder can be used as an ingredient in pet food formulations. It is often added to enhance the nutritional profile of the food, as keratin hydrolysate is a good source of amino acids. These amino acids are essential for various physiological functions in pets, including muscle development, tissue repair, and the maintenance of a healthy coat and skin.

By incorporating spray-dried keratin hydrolysate into pet food, manufacturers aim to provide pets with a balanced and nutritious diet that supports their overall health and well-being.
