The jackfruit (Artocarpus heterophilus Lam) is a large fruit with edible pulp and seeds. It is composed by the union of simple fruits, welded around a central axis. The seeds are wrapped individually by one flesh (berry) yellow, aromatic, sweet, hard to soft consistency. The seed is a byproduct of agribusiness, this can be eaten cooked, roasted or baked. Furthermore, the seeds have potential for use in food formulations because of the starch content and protein. However, jackfruit seeds is potentially even more noble, since 2010-2013 the jackfruit seed was identified as an ingredient with the aroma of chocolate in a project financed by FAPESP premises ESALQ /USP coordinated by Professor Solange G. C. Brazaca. Products like coffee and chocolate have unique aroma and flavor, due to the presence of compounds from the roasting and fermentation processes to which they were subjected. Examples of such heterocyclic compounds the (2- furilmetanotiol, caveofurano, N- furyl- 2-methyl- pyrrole) on coffee, and 3 - hexanone, menthone, hexanol, phenyl acetaldehyde, N-methyl pyrrole - 2 -aldehyde chocolate. The roasting and fermentation are also used in effective substitutes such as carob cocoa and cupuaçu. The results obtained between 2010 and 2013 showed that the seeds of jackfruit (varieties hard), among the varieties evaluated, stood out as the intense aroma of chocolate. However to date there have been further studies that evaluate which one the best (method to obtain flour with jackfruit seeds aroma similar to chocolate, or even the association with obtaining parameters of human perception as much of the ingredient as its application in food formulation. Thus the main objective of this research is to study the production of seeds toasted flour fermented or acidified jackfruit (hard) to obtain similar aroma to chocolate. Evaluating its composition, the human olfactory identification and its use in food formulation and effective substitute chocolate. (AU)
