Abstract
Huaimi is a precious Chinese herbal medicine mainly containing rutin. In this study, Cyan Huaimi (CH) and Golden Huaimi (GH) were introduced at various stages of beer production. A total of 8 beer groups and 1 control group were set up to compare their physicochemical, bioactivity, volatile compounds and sensory characteristics. The results indicated that compared with the control group, adding Huaimi significantly reduced the pH and real extract of beer, and improved the other Physicochemical parameters. Furthermore, the addition of Huaimi brought higher levels of total polyphenols, flavonoids, and phenols compounds in 8 beer groups, particularly rutin content, reaching as high as 212.69 mg/L. Moreover, through the evaluation of DPPH, ABTS, and reducing power methods revealed that adding Huaimi at the boiling stage benefited most in improving antioxidant capacity. However, the results of sensory evaluation demonstrated that panelists preferred the beer with Huaimi added at the saccharification stage because of its smoother foam. Volatiles analysis revealed that adding Huaimi introduced twelve new volatiles to the beer, enhancing its flavor and taste complexity.
期刊介绍:
International Journal of Gastronomy and Food Science is a peer-reviewed journal that explicitly focuses on the interface of food science and gastronomy. Articles focusing only on food science will not be considered. This journal equally encourages both scientists and chefs to publish original scientific papers, review articles and original culinary works. We seek articles with clear evidence of this interaction. From a scientific perspective, this publication aims to become the home for research from the whole community of food science and gastronomy.
IJGFS explores all aspects related to the growing field of the interaction of gastronomy and food science, in areas such as food chemistry, food technology and culinary techniques, food microbiology, genetics, sensory science, neuroscience, psychology, culinary concepts, culinary trends, and gastronomic experience (all the elements that contribute to the appreciation and enjoyment of the meal. Also relevant is research on science-based educational programs in gastronomy, anthropology, gastronomic history and food sociology. All these areas of knowledge are crucial to gastronomy, as they contribute to a better understanding of this broad term and its practical implications for science and society.
