Abstract

The present research work was based on evaluating the effects of Eucommia ulmoides leaf extract (EULE) on the technological quality and protein oxidation of cooked pork sausage during refrigerated storage. Sausages were manufactured with different levels of EULE (0, 0.15, and 0.3 g/kg) and stored at 4 °C for 3, 20, and 40 d, respectively. Quality attributes including cooking loss, texture, and color were evaluated, and the total carbonyl and total sulfhydryl as well as the specific markers α-aminoadipic acid semialdehyde (AAS) and lysinonorleucine (LNL) were analyzed for protein oxidation. The results revealed that the inclusion of EULE exhibited effectiveness in reducing the formation of protein carbonyls, particularly AAS and LNL, while inhibiting the loss of total sulfhydryl. Nevertheless, EULE increased the cooking loss, hardness, and chewiness of the sausages compared to the control group. These findings demonstrated that EULE could be considered a potential natural antioxidant for use in sausage production.

期刊介绍： Foods (ISSN 2304-8158) is an international, peer-reviewed scientific open access journal which provides an advanced forum for studies related to all aspects of food research. It publishes reviews, regular research papers and short communications. Our aim is to encourage scientists, researchers, and other food professionals to publish their experimental and theoretical results in as much detail as possible or share their knowledge with as much readers unlimitedly as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. There are, in addition, unique features of this journal: manuscripts regarding research proposals and research ideas will be particularly welcomed electronic files or software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material we also accept manuscripts communicating to a broader audience with regard to research projects financed with public funds
