The food industry has long used thermal technologies to preserve food in large batches. Recent advancements in infrared heating were made through research in Mexico on the preservation of bean flour. Infrared heating is generally considered to be an improvement over more conventional thermal preservation methods: whereas conventional methods transfer energy from the surface of a food to its interior, infrared heating uses high-intensity infrared light to generate heat within the food itself, thus reducing industrial cooking times.
Which choice best describes the function of the underlined portion in the text as a whole?
It emphasizes the simplicity of infrared heating technologies.
A
It explains why conventional heating methods are popular in commercial applications and proposes a shift away from these methods.
B
It suggests that there are possible flaws in infrared heating technologies that have not yet been well researched.
C
It identifies an advantage that infrared heating has over conventional thermal preservation methods.
D
