Effects of Çemen pastes prepared in different formulations on physicochemical, microbiological, and textural properties of beef hamburger patties during refrigerated storage

Abstract

AbstractThis study aimed to investigate the effects of çemen pastes prepared in different formulations on physicochemical, microbiological, and textural properties of hamburgers during refrigerated storage (4°C; 60 d). Çemen pastes were produced by using different combination doses of fenugreek seed flour, sweet red pepper, and garlic powder. As a result of çemen paste usage in hamburgers, cooking losses and dimensional shrinkage decreased, whereas moisture and fat retention ratios increased (p < .05). The hardness, gumminess, and chewiness values of hamburgers containing çemen paste were generally lower than those of control (p < .05). Çemen paste addition to hamburgers generally did not cause a difference in terms of microbial growth and moisture, fat and ash contents. Protein contents of hamburgers containing çemen paste or breadcrumbs were generally higher than that of control (p < .05). Çemen paste usage in hamburgers generally decreased the L* values and increased the b* values (p < .05). In general, addition of 3.5% or higher doses of both sweet red pepper and garlic powder caused higher a* values in hamburger patties (p < .05). Lower oxidation levels were generally observed in hamburgers containing 3% or lower doses of fenugreek seed flour and 4.5% of garlic powder in çemen paste (p < .05). It was concluded that çemen paste usage in hamburger patty processing has the potential to improve the quality characteristics and delay oxidative changes.
