Abstract
The effects of cowpea (Vigna unguiculata) flour on some physical, chemical, textural and sensory properties of Kırklareli meatballs were investigated. For this purpose, cowpea flour was added to the traditional Kırklareli meatball formulation in four different proportions (2, 4, 6 and 8%). As a result of the analysis on cowpea flour; pH, water activity (aw), moisture, protein, fat, ash, carbohydrate, acidity, starch, total dietary fiber, total monounsaturated fatty acids, total polyunsaturated fatty acids, total unsaturated fatty acids and total saturated fatty acids were found as 6.25, 0.52, 10.20, 20.35, 0.53, 2.94, 65.43%, 0.06, 45.09, 20.90, 5.86, 59.88, 65.74 and 34.26%, respectively. Depending on the increase in incorporation rate of cowpea flour, changes in L* (43,40-53,88), b* (13,92-18,11), pH (5,83-5,94), aw (0,96-0,98), moisture (44,03-50,63%), protein (17,70-21,89%), fat (19,49-22,97%), carbohydrate (6,77-12,11%), salt (1,28-1,74%), total dietary fiber (2,81-5,08%) values of the raw samples and a* (5,64-9,44), b* (9,77-18,06), moisture (39,27-45,24%), protein (19,92-23,45%), fat (23,08-26,19%), carbohydrate (5,92-11,30%), total dietary fiber (3,28-5,40%) values of the cooked Kırklareli meatball samples were statistically significant (P < 0.05), while the changes in weight loss, ash, free fatty acidity, texture and sensory results were found insignificant (P > 0.05). Total saturated, total unsaturated and trans fatty acid contents of cowpea flour added meatball samples were significantly (P < 0.05) different from the control samples. In the sensory analysis, meatball samples with 4% cowpea flour received the highest general acceptability score. According to the obtained data, cowpea flour can be added up to 4% on basic meat values without changing the textural and sensory properties of Kırklareli meatballs. Cowpea flour could be added as a functional ingredient in meatballs.Graphical
