It has been shown that the physical properties of three anti-caking conditioners added garlic powders can be monitored and evaluated by some tests. The test parameters obtained are all quantifiable for powders fundamental properties. It is clear that cellulose powder and calcium carbonate are not attributed to the particle surface improvement effects. When SSA added 2% (w/w) for garilic powder which is improved flow ability and attractive index. Bulk density and compressibility were more sensitive indices to changes occurring in some conditioner added garlic powders.
