Which term completes the sentence: '_____________ involves forcing the milk through small openings under high pressure, thus breaking up the fat globules and producing a stabilized emulsion'

• A. Pasteurization
• B. Sterilization
• C. Clarification
• D. Homogenization

Answer: (D)

The process described is homogenization. In homogenization, milk is forced through small openings under high pressure, which creates intense shear that breaks the fat globules into many tiny droplets. These smaller fat droplets stay suspended in the liquid because proteins and phospholipids rapidly coat their surfaces, forming a stable emulsion that prevents the fat from aggregating and separating out. This gives milk a uniform texture and prevents cream from rising to the top. This differs from pasteurization, which uses heat to kill microbes; sterilization, which uses even more extreme heat; and clarification, which removes solids to produce a clearer liquid. None of those processes focus on breaking fat globules or stabilizing the fat droplets into a stable emulsion like homogenization does.
