The influence of under-fermented (UF) cocoa (0 to 65 %) on bioactive amines in chocolate and their in vitro bioaccessibility was investigated. The same amines were found in all treatments; however, treatments were divided into two groups regarding total amines [0 & 20 % UF (34 mg/kg) and 35 to 65 % UF (17 mg/kg)] and phenolic levels [lower and higher, respectively]. Serotonin, tyramine, putrescine, cadaverine, agmatine and phenylethylamine were higher in chocolate with ≤ 20 % UF cocoa.

Considering the limited information on the bioaccessibility of these compounds from chocolate, the objective of this study was to characterize their profiles and bioaccessibility in 70% cocoa dark chocolate through in vitro simulation of oral, gastric and intestinal digestions. Seven amines were detected; polyamines were predominant before in vitro digestion, whereas tyramine, cadaverine and spermidine after digestion.

Fresh Agaricus bisporus mushroom was submitted to cooking and canning and samples were submitted to in vitro gastric and gastric-intestinal digestions. An UHPLC method was used for the simultaneous determination of 18 free amino acids, 10 biogenic amines and ammonia in the samples.

However, because of the atmospheric pollution and soil contamination associated with urban areas, this activity may be of concern. In fact, contamination of soil with metals and the transference of contaminants to vegetables can represent health and safety risks associated with urban agriculture.
