To increase the palatability, processors often use sugars, meat by-products, enzyme digests and some other natural components.

Palatability means more than just adding a flavour. Increasing the palatability of pet food involves oxidation, mould control and selection of a good and appropriate palatant.

In addition, shelf life stability as well as impact of individual ingredients on taste needs to be taken into account when adding flavours. The easiest way to improve palatability is to provide enhancers which can provide a significant improvement at low inclusion levels.

Much research
Research with flavour enhancers has proliferated intensely and many different flavour enhancers of liquid and dry types are available ranging from those added in minute quantities to macro additives.

Widely known enhancers for dogs include sugars, meat by-products, enzyme digests and some other natural components. Animal proteins, including fresh unrendered vegetable-based products, are commonly used as well.
