This study aimed to evaluate the volatile compounds of chocolates made of Brazilian cocoas and statistically track them according to the products sensorial profile in order to relate them to consumers’ acceptance by preference map methodol. The intensity of the chocolate, acidity, woody, smoked, green, floral, burned, musty, and cocoa notes from chocolates produced with cocoa from different Brazilian states were analyzed by a trained panel and by 128 consumers. Samples from Cote dIvoire, which is known for its high-quality chocolate, were evaluated for comparison. Solid-phase microextraction headspace sampling/gas chromatog.-mass spectrometry was employed to evaluate the samples volatile compounds One hundred volatile compounds were identified within the samples. The results from the preference maps showed that the maximum preference was found for chocolate made of cocoa from Rondonia, Bahia, and Espirito Santo and Cote dIvoire and organic samples from Para. The ideal sample point was characterized by intense chocolate, floral, and woody notes and mild green and burned notes. The presence of furfural, 3-Me butanal, phenethyl acetate, 2-phenyl-5-methyl-2-hexenal, Me pyrazine, phenethyl acetate, 2-phenyl-5-methyl-2-hexenal, and tetra-Me pyrazine were shown to be important for consumer acceptance in the ideal product, whereas the presence of (Z)-2-heptenal and 2-pentyl furan may increase consumer rejection. 2,3-Me pyrazine, Me pyrazine, and 2,3-butanediol, which are important volatile compounds previously reported in the literature, were statistically tracked to both pos. and neg. sample attributes and must be better explored concerning consumers acceptance of chocolates. In the experiment, the researchers used many compounds, for example, Oct-1-en-3-ol (cas: 3391-86-4Related Products of 3391-86-4).
Oct-1-en-3-ol (cas: 3391-86-4) belongs to alcohols. A strong base can deprotonate an alcohol to yield an alkoxide ion (R―O−). For example, sodamide (NaNH2), a very strong base, abstracts the hydrogen atom of an alcohol. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Related Products of 3391-86-4
