Effects of animal fat replacement with almond flour on quality parameters of beef patties

Abstract

Almond is rich in vitamins, minerals, and dietary fiber and contains high fat and protein. For this reason, almond flour can be used as an additive in the production of various foods to increase nutritional value, improve texture and flavor, and produce healthier products. The purpose of this study is to determine the availability of almond flour as an animal fat replacer in the production of beef patties. For this purpose, beef patties were produced in five different formulations containing animal fat and/or almond flour, and pH, moisture content, color, and TBARS values were detected in both raw and cooked samples. In addition, cooking yield and shrinkage were calculated and fatty acid composition, texture profile, and sensory analyses were performed on cooked samples. Replacing animal fat with almond flour increased pH in raw and cooked beef patties but decreased moisture content, b* value, and TBARS in cooked samples compared to the control. While cooking yield increased in beef patties containing almond flour, shrinkage decreased. In addition, the cooking process caused decreases in L*, a*, and b* values. Using almond flour in beef patties decreased the SFAs and increased the amounts of oleic and linoleic acids. Hardness, cohesiveness, resilience, and chewiness were significantly affected by the use of almond flour (p < .01), and higher hardness and chewiness, and lower cohesiveness and resilience were determined in the samples containing almond flour compared to the control. On the other hand, the use of almond flour instead of animal fat in beef patties did not have a significant effect on the determined sensory properties (p > .05).
