Abstract
This study aims to explore the effects of different pHu ranges [pH < 5.8 (normal); 5.8 ≤ pH < 6.2 (intermediate); and pH ≥ 6.2 (high)] on lipid oxidation in steaks of Longissimus lumborum beef aged for up to 28 days that were grilled or grilled-chilled and reheated. The steaks were cut, vacuum-packed, and aged under vacuum at 2 °C. As major results, the fresh meat with normal pHu showed statistically higher thiobarbituric acid reactive species values than the meat within the other pHu ranges. Accordingly, after grilling-chilling and reheating, the concentration of benzaldehyde, which is a product from thermal degradation of amino acids, fatty acids and other aldehydes, was higher in the meat with normal pHu and lower in the meat with high pHu. Overall, our results contribute to the knowledge of the effects of pHu variations on lipid oxidation and warmed-over flavour in meat after grilling-chilling and reheating.
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.
