This paper has given an account of and the reasons for the use of
ultrasound in the food industry. This study was designed to
determine the effects of different ultrasound powers (30 W, 60 W,
90 W) and treatment times (5M, 10M) on quality of strawberry.
Contrary to expectations, this study did not find a significant
difference between treatment times. It was however found that,
ultrasound power between 30Wand 60Wcould be used to extend
shelf life of strawberry. It was observed that the high power
ultrasound (90 W or higher) presents detrimental effects on
strawberry quality. The empirical findings in this study provide
a new understanding of ultrasound power. Finally, this research has
