The use of chloroplast markers for the traceability of certified sustainably produced cacao (Theobroma cacao) in the chocolate industry (2018)
Conference Proceeding
Allainguillaume, J., & wetten, A. (2018). The use of chloroplast markers for the traceability of certified sustainably produced cacao (Theobroma cacao) in the chocolate industry. In International Cocoa Symposium 2017 Proceedings

Recently the chocolate industry has changed to a higher demand for sustainably certified cacao (Rainforest Alliance, UTZ, and FairTrade) and closer attention is being paid to how this sustainably produced cocoa can be traced. Companies like Mars, Her... Read More about The use of chloroplast markers for the traceability of certified sustainably produced cacao (Theobroma cacao) in the chocolate industry.
