_________ is a process that uses sublimation to prepare high-
quality preserved foods.
Pulsed light processing
,Ozonation
Modified atmospheric packaging
Freeze-drying Correct Answers The correct answer is D.
Sublimation is defined as "the transition from the frozen state
directly to the gaseous state without liquefaction" and is used in
food processing to produce foods with superior flavor profiles,
color retention, and results in a product that is both light in
weight and airy in texture. When freeze-drying, foods in the
frozen state are placed in a vacuum chamber to extract all frozen
water from the food's molecules, resulting in a food that has
been dehydrated while in the frozen state.
___________ is a processing method used to extend shelf life of
beverages such as milk and juice.
Dehydration
Canning
Freezing
Pasteurization Correct Answers The correct answer is D.
