Ultrasonic detection of adulteration in fluid foods

Fluid foods, like, milk, honey, alcohol, fruit juices and other beverages fall easy prey to adulteration as a number of cheap liquids are easily miscible with them. Sometimes, they are highly toxic and when mixed unscrupulously with liquids for human consumption, may cause serious health problems. Propagation of ultrasonic waves through the fluid foods was studied because mixing of adulterants in them changes their physical properties, such as density, viscosity and homogeneity, etc. These have direct impact on the velocity of ultrasonic waves passing through these media. This study would help in easy and quick detection of adulteration in fluid foods thereby resulting in better health care of the masses.
