Abstract—The effects of ultrasound on coconut milk homogenization were studied. An ultrasonic generator was used to homogenize 100 mL of coconut juice with certain energy levels and exposure times. All samples were analyzed under microscope at 1000× magnification to determine the diameters of fat globules. It was found that ultrasonic treatment with high power level has an important effect on coconut milk homogenization and is an effective technique for the reduction of the fat globule size. Effect of reduction represents the symptom of cavitations phenomenon.
