Optimization of a macro-element extraction system from cocoa honey samples using ultrasound and Doehlert design with multiple responses.

Cocoa honey is a product obtained at the beginning of the cocoa bean fermentation process that gets its name from its sweet flavor. Information about its chemical composition is still rarely explored in the literature. A simple, fast, and low-cost procedure of sample preparation based on ultrasound extraction and MIP OES was developed to determine the amounts of Ca, K, Mg, and P found in cocoa honey samples.
