Alternatives to increase fruit shelf life without the addition of synthetic preserva-tives, such as the use of edible coatings incorporated with bioactive compounds, should be explored. This study evaluated the effects of edible coating with fish pro-tein hydrolysate on the quality and shelf life of cherry tomatoes. The cherry tomatoes were divided into four treatments: Control; coated with glycerol (5%; w/v); coated with glycerol (5%; w/v) and added with protein hydrolysate (1%; w/v) and coated with glycerol (5%; w/v) and added with protein hydrolysate (2%; w/v). The coated or uncoated cherry tomatoes were evaluated at 0, 7, 14, 21, and 45 days of chilled or room temperature storage for color, weight loss, firmness, soluble solids, pH, and molds and yeasts. The microbiological data suggested the edible coating with protein hydrolysate has bioactivity because inhibited the proliferation of molds and yeasts. However, in the other analyses showed no superior shelf life compared to the control. |

Abstract: The distinct properties of cocoa beans may be due to their different geographical and genetic origins which lead to chocolates with different characteristics. This study aimed to evaluate dark chocolate samples made with hybrid cocoa cultivated in the Bahia State, Brazil, regarding the composition of bioactive compounds (spectrophotometry, High Performance Liquid Chromatography) and the sensory characteristics (Quantitative Descriptive Analysis-QDA®), and acceptance test). External preference mapping was conducted by first using principal components analysis (PCA) on the QDA data, and then relating consumer preference (overall liking) to this PCA space by regression analysis. Significant differences among the cocoa varieties were found. Chocolate samples that showed lower acceptability also presented higher content of theobromine, caffeine, anthocyanins, and gallic acid which conferred greater intensities of bitterness, astringency, and intense cocoa flavor. Lower levels of methylxanthines, monomeric phenolic compounds, and anthocyanins allowed the highlight of fruity, sweet and caramelized notes, which contributed to greater acceptance of the chocolate samples. Therefore, these characteristics can be recognized as consumer preference drivers (negative and positive, respectively) for the high cocoa chocolates. It seems that higher values of ephicatechin and catechin had no negative contribution to the flavor of the chocolate samples. The findings of this study can be used in agriculture and in the cocoa/chocolate industry, suggesting the potential and applicability of promising hybrid cocoa, with important characteristics, representing a genetic material of great quality, that may be classified as fine flavor cocoa, associating greater value to the product, and contributing to meet consumer needs.
