Arrowhead Inspection Instructions

There are no U.S. grade standards for Arrowhead. These instructions have been developed by the Fresh Products Branch to assist officially licensed inspectors in making inspections, writing certificates and to assist in the proper identification of specialty type fruits and vegetables.
 
Arrowhead (Ma Tai Koo, Sha Koo , Kuwai, Chee-Koo) is a fleshy bulb from a runner type perennial having long petioles and leaves of arrowhead shape-hence the name. It grows
in marshy or swampy areas. Arrowhead is widely cultivated in Hong Kong, China and some South Pacific Islands. It is marketed in Europe. It is a prolific aquatic plant and when planted will send out eight or more runners as soon as the root system is established. Each of these runners will produce a new bulb at its end. Arrowhead when cut is yellow-buff and has the consistency of a sweet potato. Each bulb weighs approximately one-half to 1 ounce. Arrowhead should be cooked before eating.
