Mixing without oxidation of additives
Dinnissen Process Technology in Sevenum (the Netherlands) is
developing a new method to protect liquid as well as powdered vitamins,
enzymes, pre- and probiotics against oxidation.
Micro-ingredients such as vitamins, enzymes,
pre- and probiotics play a crucial role in concentrated feeds and diet feeds.
However, vitamins, enzymes, pre- and probiotics which are added to feed pellets
in only minute amounts are very fragile. Contact with oxygen causes certain
nutritional compounds to become oxidized and lose much of their effectiveness.
This can easily happen during the transport and storage of the
Based on existing
technology that had been applied earlier for the production of baby foods and
premium diet foods for pets, Dinnissen Process Technology now uses the
technique for cattle feed. The Pegasusâ
Mixer makes it possible to spray vitamins, enzymes, pre- and probiotics in
predefined and very accurate quantities onto the surface of cattle feeds and, in
addition, to optimize process conditions such as temperature, residence time and
After being sprayed onto the pellets, the tiny
quantities of micro-ingredients are transported deep inside the pellet with the
help of the special Pegasusâ
thereby protecting them from falling off and from contact with
Dinnissen Process Technology has
high hopes for this new technology. Henri Michiels, company director: "We expect
to be able to improve the effectiveness of (cattle) feeds with this new
technology, thereby enabling cattle farmers to realize improved results. This
new method creates opportunities in the feed sector to develop improved feed
products and to reduce the use of aggressive acids. The latter are now often
used to improve the shelf life of vitamins, enzymes and pre- and probiotics."
