question 13

Multiple Choice

What is the difference between fermented food and spoiled food?

• A) Fermented foods are made using certain genera of bacteria only. Spoilage of food involves bacteria, molds, AND yeasts.
• B) Fermented foods are changed by microbes but are edible. Spoiled foods are also changed by microbes but are full of microbial toxins that always lead to illness.
• C) Fermented foods may change in appearance but they taste the same as non-fermented foods. Spoiled foods look the same as unspoiled foods but they taste different.
• D) Fermented foods are intentionally altered during production by carefully controlling the activity of bacteria, yeasts, or molds. Spoiled foods have microbe-induced changes that are undesirable.
• E) Fermented foods result from undesirable changes made by microbes. Spoiled foods result from desirable changes made by the same types of microbes.
