Aquasta ®
DESCRIPTION
Aquasta ®
is Astaxanthin Partners Ltd's trade
name for its inactivated dried yeast product made from the
organism Phaffia rhodozyma. Aquasta®
provides a natural
source of the pigment astaxanthin, which imparts the
characteristic red color to the flesh of salmon, trout, and other
aquatic species. Astaxanthin Partners Ltd's yeast is specially
formulated to maximize bioavailability of the pigment.
APPLICATION
Aquasta ®
is a free-flowing granular powder
that can be readily blended with other feed ingredients to meet
formulator's specifications. Aquasta®
is available with different concentrations of astaxanthin and this
has to be considered to calculate the appropriate inclusion
rate. For example, if the astaxanthin content is 10,000ppm,
and the target is to obtain 60 mg/kg astaxanthin in the feed, 6 kg
of Aquasta® should
be incorporated per tonne of feed.
This product is for use as a coloring agent in
fish feeds at a rate not to exceed 100 mg/kg astaxanthin in the feed.
