Gökkuşağı Alabalık (Oncorhynchus mykiss Walbaum, 1792) Kıyması ile Üretilmiş Geleneksel Türk İçli Köftesinin Besinsel Komposizyonu ve Dondurularak Depolama Boyunca (-18ºC) Renk ve Duyusal Kalitesinin Belirlenmesi

Abstract

The nutritional value of stuffed meatballs made with minced rainbow trout rather than red meat in the stuffing was investigated, as well as color variations (L *, a *, and b *) and sensory quality, using two different cooking methods (boiling and frying) on samples stored in the freezer (-18 oC). As a result of this research, the moisture, the crude ash, the lipid, and the crude protein contents of stuffed meatballs produced with rainbow trout were found as %58.25 ± 0.93, %2.01 ± 0.05, %5.28 ± 0.29, and %7.69± 0.08, respectively. The content of total saturated fatty acids composition (∑SFA), total monounsaturated fatty acids composition (∑MUFA), and total polyunsaturated fatty acids composition (∑PUFA) was found to be 12.52 ± 0.23%, 39.11 ± 1.27%, and 43.73 ± 1.98%, respectively. The atherogenic (AI) and thrombogenic indexes (TI) for dietary factors associated with cardiovascular disease were found to be 0.10 and 0.25, respectively. In the evaluation of color (L *, a *, and b *) of frozen samples, L * (black-white) and b * (blue-yellow) values in all groups (raw, boiled, and fried) increased significantly at the end of storage compared to the initial value ( p<0.05). Following frying and boiling, the * (green-red) values of the frozen-stored samples decreased significantly (p<0,05). Sensory quality was assessed in this study using two cooking methods: boiling and fried, both of which are common serving methods for stuffed meatballs. Although a significant decrease was detected in all sensory quality parameters of samples during frozen storage, it was determined that it did not reach the unacceptable limit at the end of storage.
