C Chapter 27 Homework MicroCareers: You Are what You Eat! -Food Microbiologist 2 of 12> Food microbiologists are scientists who have a background in both microbiology and food science. They focus on how microbes grow, cause disease, and how they can be identified from food. Their work is of importance to the food industry as it relates to the production, preservation, and spoilage of food; and it is of importance to public health and regulatory agencies due to the many diseases that are related to food intake and consumption. Food microbiologists can have varying backgrounds, including training in veterinary medicine. This scenario is about a food microbiologist who works as a food safety inspector who pays a visit to a cheese manufacturing plant and makes some interesting discoveries Part A-Understanding the Role of Microbes in Fermentation The Midwest is known for its contribution to the dairy industry Fermented dairy products include milk, yogurt, and cheese. The fermentation process relies on lactic acid bacteria and pasteurization. Fermentation can vary based on what food is being produced, the type of bacteria used to produce lactic acid, and the time and temperature of pasteurization. It is important to the manufacturer to produce a product that won't spoil before it is packaged and sold and that won't result in disease for those who ingest and enjoy it. Julie, a food inspector for a local Michigan health department is going to a nearby cheese plant for a biannual inspection. When she gets there, she will take a tour of the plant and allow the operators to describe what makes their cheese so special. She will use what she understands about fermentation to inquire about their production practices Please sort the following statements as being true or false regarding fermentation and its role in food production. Please recall the role that microorganisms can play in the production of foods.

Correct statements:
Fermentation occurs when undesirable metabolic reactions allow for the growth of pathogens or the presence of unwanted microorganisms in food.
Starter cultures are used to initiate the process of fermentation in modern food processing.
Some grains, vegetables and fruits have their own microbes that facilitate fermentation.
Lactic acid is production by certain microorganisms and aids in fermentation.
Incorrect statements:
Fermentation can be used only to make dairy products.
Bacteria are the only microorganisms used in the fermentation process.
Fermentation allow for sugars to be broken down or metabolized to make food such as bread, vegetables and cheese.
