What can’t Masterflex® peristaltic pumps do?

October 28, 2010

Who doesn’t love the great taste of caviar?  This gourmet hors d’oevre is considered a luxury delicacy.  Caviar is the salted, non-fertilized roe, or ripe internal ovaries or egg masses of fish and certain marine animals, and more commonly from the sturgeon species of fish.  Harvesting caviar has become regulated over the years, particularly as some species of Beluga sturgeon are now endangered.  The high price of caviar, and the harsh methods of collecting the sturgeon roe, discourage some from indulging in this delicacy.

However, there are alternatives to the traditional caviar or fish eggs. The method of producing these alternatives is much more cost-effective and certainly less taxing on the sturgeon.  One company uses kelp, a marine plant filled with nutrients, which is fat free, cholesterol free, and has zero calories.  Plus, because kelp caviar is a plant, this “caviar” may appeal to vegetarians.

The kelp is ground into a thick gelatinous solution and, with the help of a Masterflex® pump, the solution is pumped through a separator which outputs tiny kelp “pearls.”  This brief video shows how kelp caviar is made with a Masterflex pump, and raises the question, what can’t you do with a Masterflex pump?
