Abstract
Opuntia ficus-indica is a subtropical fruit rich in dietary fibers, carotenoids, vitamins, minerals, and polyphenols. To substitute synthetic additives, its extracts could become an interesting proposal to preserve quality while adding desirable characteristics to meat products. This study aimed to develop healthier chicken patties (with a structured animal fat replacer) added with prickly pear extract (PPE). The extract was analyzed for total phenolic content and antioxidant activity (FRAP, ABTS, DPPH, and ORAC). Four chicken patty formulations were manufactured with total replacement of animal fat by sesame oil emulsion: control, erythorbate 500 ppm, PPE 500, and PPE 750 ppm. Proximate composition and fatty acid profile were analyzed on day 1, and pH, color, and lipid oxidation on days 1, 4, 8, 12, and 16. PPE treatments showed lower TBARSs (p < 0.05) and greater pigment stability at the end of storage, corroborating its potential to delay oxidation reactions. No significant effects on chemical composition, pH, or fatty acid profile were observed (p > 0.05). Unsaturated represented 76.2% of total fatty acids. Therefore, PPE is an effective antioxidant by improving oxidative stability without promoting changes in other properties, besides adding cleaner label approaches and the use of natural ingredients to develop meat products reformulated with unsaturated oils.
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
