Testing for Corn Mold

Описание: These Virtual Labs help students learn basic laboratory techniques and practice methods used by lab technicians and researchers in a variety of careers, using specific food science lab processes.
The process of testing corn for the presence of aflatoxin.

Corn that is intended for consumption by humans or animals must be tested for the presence of the dangerous Aspergillus mold, which produces a toxin. In this virtual lab, look at a sample of corn under black light to see if it glows. Then, grind up the corn, prepare a solution, and use a test strip to determine whether aflatoxin is present. You’ll practice using a pipette, adding solvent to extract toxins, diluting a solution, and maintaining consistent procedures.
