Based on current clinical research, it has been
proven that chondroitin sulfate and glucosamine
are benefitial to human and animal joint tissue.
Both chondroitin sulfate and glucosamine have become
important nutrition compositions in pet foods and
animal feeds. Certain raw materials in pet foods
and animal feeds, such as animal cartilage, bone
and trachea, contain chondroitin sulfate in a bound
form (attached to protein and some other substances),
and glucosamine, from shrimp and crab shells, in
varying percentages. Other raw materials might also
contain bound chondroitin sulfate and glucosamine.
Analytical Laboratories in Anaheim, Inc. has developed method utilizing special pre-digestion
procedures to release the free chondroitin sulfate
and glucosamine from their bound form. The free
chondroitin sulfate can be quantitated by enzymatic-HPLC
method, a specific and sensitive method for chondroitin
sulfate. Free glucosamine is tested by a pre-column
derivatization method. Any pre-existing free chondroitin
sulfate and glucosamine (usually is spiked to
the finished products) will be included in the
final result. The detection limit for chondroitin
sulfate is <0.02%; for glucosamine is <0.01%.
Analytical Laboratories in Anaheim, Inc. is able
to test total (bound & free) chondroitin sulfate
and glucosamine in any form of pet food and animal
feed (such as canned food, dry form, biscuit,
etc.), as well as R & D products and raw materials.
