How do you determine the density and moisture content of a food sample?

Answer 1

The density is the mass divided by the volume. So weigh the food to get it's mass. Then imerse it in some liquid to see how much it makes the level rise by, that give you the volume. Divide the former by the latter to give density.

To get the moisture content you weigh the food before and after completely drying it in an oven. The difference in weights gives you the weight of the moisture initially present in the food.

Answer 2

I work in a food processing plant, and they use machines to calibrate the moisture, ash, density, and protein of a product.
I don't know of any way that you can do it without some sort of equipment.

Answer 3

Using a pyknometer.
