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 preventing Clostridium botulinum growth in salsa.
Adding acidic ingredients is an important way to protect foods from dangerous toxins produced by organisms like C. botulinum, a microbe that is common and harmless in the environment but deadly when sealed with food in a jar. In the lab, testing the pH of a substance (how acidic or basic it is) provides important information for ensuring food safety. This module introduces users to proper sampling techniques when testing pH and explains how adjusting a food’s acidity can keep it safe from C. bot.
Virtual Labs: Acidifying Salsa familiarizes the user with food science lab equipment and teaches standard techniques for sampling. The interactive covers theory and practice of adjusting pH, so learners will have familiarity with concepts and procedures when encountered in a real lab.
