No. The $250 test covers identity, purity and quantity by a chromatographic assay, with detection selected for the compound. Full testing to the USP Cocoa Butter monograph is available and quoted.
Cocoa butter is a mixture of triglycerides. The fatty acids are converted to methyl esters and measured by chromatography, which gives the fatty acid profile that identifies the fat.
The fatty acid profile is the main check. Cocoa butter is rich in palmitic, stearic and oleic acids, and blending with other fats shifts that profile.
No. Cocoa butter can set in several crystal forms with different melting behavior, and the $250 test reports composition and purity only.
