Sample interview questions: Are you knowledgeable about any specific techniques or methods for analyzing food or beverage samples?
Sample answer:
-
Gas chromatography-mass spectrometry (GC-MS): This technique separates and identifies volatile compounds in food and beverage samples. It is commonly used to detect pesticides, flavor compounds, and other volatile organic compounds.
-
High-performance liquid chromatography (HPLC): This technique separates and identifies non-volatile compounds in food and beverage samples. It is commonly used to detect sugars, organic acids, and other non-volatile compounds.
-
Spectrophotometry: This technique measures the absorbance of light by food and beverage samples. It is commonly used to determine the concentration of specific compounds, such as proteins, sugars, and vitamins.
-
Enzymatic assays: These assays use enzymes to measure the concentration of specific compounds in food and beverage samples. They are commonly used to determine the activity of enzymes, such as proteases, lipases, and amylases.
-
Microbiological testing: This testing involves culturing and identifying microorganisms in food and beverage samples. It is commonly used to detect pathogens, such as Salmonella, E. coli, and Listeria monocytogenes.
