Impact of Liquid Smoke and Thyme Oil on Quality of Chicken and Turkey Meatballs Chilled

Abstract

The purpose of this study was to see how liquid smoke made from beech sawdust and thyme essential oil (TEO) affected the stability of chicken and turkey meatballs when kept refrigerated. The study looked at three factors: chicken and turkey meatballs, liquid smoke and TEO concentrations (1 % and 0.1 %, respectively), and shelf life at refrigerated temperatures at 4• +1 C for (0, 3, 6, 9, 12 and 15 days). Physicochemical (moisture, crude protein, crude fat, ash, pH value, water holding capacity) and total bacterial count parameters were examined. The treatments showed a considerable favorable effect on the overall bacterial count and physicochemical parameters. During storage, the samples treated with liquid smoke, then TEO, and control lost the least amount of moisture, protein, and water holding capacity. During storage, the fat, ash, and total bacterial count increased, with the greatest levels in control and the lowest in liquid smoke, followed by TEO. The pH value has decreased during storage by addition of liquid smoke 1% compared to TEO, and control. The interaction between treatments and storage days showed significant effect (P ≤0.05) on protein, fat, pH value, water holding capacity and total bacterial count. Furthermore, the lowest change was noticed in samples treated with liquid smoke during storage. Applications of liquid smoke in meatballs reduced the rate of microbial damage, maintained the physiochemical properties and were better accepted compared to TEO and control.

Anti-Oxidative Impact of Liquid Smoke and Thyme Essential Oil on the Quality Characteristics of Chicken and Turkey Meatballs Products during Frozen Storage

“…The chicken breast and turkey meat were minced separately using a meat mincer. Some samples were used directly for physiochemical analysis at zero time, while others were prepared for processing products [25].…”
