Compared the degree of retention of polyphenols within a hot air drying technique with sun drying and discovered that–with respect to fresh samples–retention in the former system was within the 8.33.two variety, whereas inside the latter it was 11.4 3.2 [28].Antioxidant capacity[61][62][48] NR NR NR 1.548 0.001 mg/g 0.752 0.081 mg/g 1.eight Cocoa items: dark JAK2 Inhibitor Purity & Documentation chocolate Croatia NR 1.384 0.001 mg/g 1.7 Cocoa products: semi- sweet chocolate 0.416 0.011 mg/g NR NR 1.108 0.539 mg/g 1.025 0.798 mg/g Chk2 Inhibitor list Commercial cocoa: milk chocolate (MC) 1.1 Commercial cocoa: choco-syrup (CS) 1.0 Cocoa products: milk chocolate 1.three 0.242 0.027 mg/g 1.163 0.070 mg/g NRRef.NRProcyanidinsNR epicathechin 0.16 g/mL cathechin 0.13 g/mL 0.three Milk chocolate NRepicathechin 0.59 g/mL cathechin 0.32 g/mLNRTotal Polyphenols Content (mg GAE/g)Protocatechuic acid0.Table 1 (continued )CountryKoreaItalyCommercial cocoa: dark chocolate (DC)Dark chocolateMatrix4.4.269 1.761 mg/gNRNRM. Gil et al.Heliyon 7 (2021) eFinally, epicatechin the most abundant compound in the catechins household, is found in higher quantities in fresh cocoa seeds, and, by the finish with the cocoa fermentation and drying processes, epicatechin concentration is decreased by 75 [41]. The research reviewed right here have reported concentrations of epicatechin in nations such as Colombia and Ecuador, where its values have already been in between eight,256 mg/g and 1 mg/g in unfermented dry samples and in fermented dry cocoa, respectively, which highlights the impact of fermentation on the loss of this compound. The same behavior has been observed with regards to anthocyanins, which are affected by the fermentation and drying course of action, as verified in two studies carried out in Colombia. Within the first one, the authors applied the ICS-1 clone, as well as the total anthocyanin content reduce from 1.26 0.045 mg/g to 1.05 0.021 mg/g. The second study investigated a mixture of clones in 3 regions and reported an average lower of 67.2 0.01 ; in that case, the greatest adjust occurred from two.63 0.12 to 0.84 0.04 [44,74]. Monitoring the anthocyanin concentration in the clone mixture, it was observed that between 72 and 96 h of fermentation and optimal conditions (45 C in addition to a pH in between 3.eight and 4.five) made the greatest advance in hydrolysis of anthocyanins. This was possibly as a result of action of glucosidase enzymes causing the breaking of your glycosidic bond of the two major fractions of anthocyanins present in cocoa (i.e., cyanidin-3-O-galactoside and cyanidin-3-O-arabinoside), that are hydrolyzed to anthocyanidins. This lower in anthocyanins, is linked using a color adjust (decrease in violet) throughout postharvest, is usually a sensible indicator for producers, permitting them to visually differentiate the stage of fermentation. 3.2. Industrialization 3.2.1. Roasted matrix Cocoa roasting is actually a decisive step in aroma development as a result of interaction of flavor precursors resulting from fermentation. Good roasting prevents sensorial defects for instance bitter, acidic, astringent and nutty flavors. Nonetheless, within this course of action, nutrients and functional compounds responsible for well being advantages (e.g., polyphenols) are lost, and also the thermic contaminants for instance acrylamide are generated [58]. Additionally, roasting can market lipid oxidation and non-enzymatic browning, which tremendously depend on the operation parameters utilized for the duration of this step and the composition of cocoa, both dried and fermented [37]. Urbnska and Kowalska (2019) reported polyphenol contents inside a chocolate ready with roaste.
