Question

how to analysis of specific gravity and bulk density of food and write requirements and methadology​

Answer 1

Answer: Specific gravity is a ratio of the density of a substance to the density of a reference substance, usually water. Since the density of water is one gram per cubic centimeter, you calculate specific gravity by dividing the density of a substance by one gram per cubic centimeter.One method uses the hydrometer, an instrument that gives a specific gravity reading directly. A second method, called the bottle method, uses a specific-gravity bottle, i.e., a flask made to hold a known volume of liquid at a specified temperature (usually 20°C).
