| Summary: | Black garlic is a processed product prepared via the heat treatment of whole garlic bulbs (<i>Allium sativum</i> L.) at high temperatures and humidity levels for several days, resulting in black cloves with a sweet taste and increased bioactive substances. The purpose of this study was to evaluate the quality, chemical and functional characteristics, and shelf life of bread with different percentages (0.5%, 1%, 2%, and 3%) of Voghiera black garlic powder (BGP). The analysis conducted on the powder showed important changes in composition, and the polyphenol content and antioxidant activity increased when the garlic was processed. The data obtained demonstrated that BGP did not modify the nutritional composition of the bread, while the total polyphenol and total flavonoid content and antioxidant activity progressively increased from 1.40 mg GAE/g, 0.28 mg CE/g, and 0.15 mg TE/g to 1.75 mg GAE/g, 0.56 mg CE/g, and 0.47 mg TE/g, respectively, as the amount of BGP increased from 1 to 3% in comparison with wheat bread. Moreover, BGP improved the shelf life of breads enhanced with 2 and 3% of powder, reducing microorganism growth and water loss; however, on the other hand, the added powder caused an increase in acidity and color intensity. At higher powder percentages, the acceptability and palatability of the bread to the consumers were reduced. |
