Next to protein, starch is one of the primary ingredients used in animal feed. However, starches from different sources offer a range of functional properties that need to be considered, not only from a nutritional perspective, but also from a technological aspect.
Starch gelatinisation is one of the three most important and effective drivers for improved pelleting, together with steam management and compression ratio/friction.
This is why information about starch (type of raw material, date of harvest, how it was stored and/or processed) should be communicated on a very frequent basis within your feed plant, i.e., shared among formulators, the production manager and operators. This is to facilitate adjustment of process parameters in parallel to the reformulation of raw materials.
