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.
