Jackfruit Seeds Could Help Ease Looming Cocoa Bean Shortage

Chocolate lovers could soon have a harder time satisfying their sweet tooth. Worldwide demand for this mouth-watering treat is outstripping the production of cocoa beans, its primary ingredient. But in a study published in the Journal of Agricultural and Food Chemistry, scientists report that compounds found in jackfruit seeds produce many of the same aromas as processed cocoa beans and are a potentially cheap, abundant substitute for use in chocolate manufacturing.



Globally, farmers produce about 3.7 million tons of cocoa annually. This yield is not expected to increase significantly in the next decade, but estimates suggest that worldwide demand for these beans will grow to 4.5 million tons by 2020. To meet growing expectations, scientists are investigating alternative sources that can mimic chocolate's distinct aroma and flavor. One of these possibilities is jackfruit, a large tropical fruit found in South America, Asia, Africa and Australia. In some countries, its sweet-smelling seeds are boiled, steamed and roasted before eating, providing a cheap source of fiber, protein and minerals. But in Brazil, the largest cocoa producer in the Americas, jackfruit seeds are considered waste. Looking to put these waste seeds to better use, Fernanda Papa Spada, Jane K. Parker, Solange Guidolin, Canniatti Brazaca and colleagues sought to determine if any of the compounds within them could be used to produce chocolate aromas.
