Abstract

Storage time greatly influences the quality of raw eggs, such as sensory changes in egg white (EW) and egg yolk (EY), decreased polyunsaturated fatty acids (PUFAs), and increased monounsaturated fatty acids (MUFAs). However, few studies have attempted to investigate its impact on further egg processing. Marinated eggs, including salt-baked marinated eggs (SBMEs), are one of the traditional egg products in China. This study thus aimed to the effects of raw egg storage time (0, 7, 14, 21, and 28 d) on the quality of SBMEs, by examining the color, texture, sensory, fatty acid composition via gas chromatography, and volatile organic compounds (VOCs) profiles via gas chromatography-ion mobility spectrometry. PUFAs and MUFAs in SBMEs made from eggs stored for 28 days decreased significantly (P < 0.05) by 10.50% and 10.54%, respectively, compared to those from fresh eggs. Aldehydes were the main substances constituting the VOC profiles of SBMEs. The main aldehydes in EW was benzaldehyde, while hexanal was found in EY. Hierarchical cluster analysis indicated that the VOCs of EY changed more rapidly compared to EW. The present study would further help to provide the industry with the indication of appropriate egg preservation measures and the subsequent processing quality control.

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.
