Preparation of a cooked and salted chicken breast product using alcalase-hydrolyzed wooden breast fillets

Abstract

Wooden breast (WB) is a myopathy characterized by functional changes and excessive hardness in chicken fillets. Alcalase, a proteinase capable of hydrolyzing meat proteins, has been shown to improve protein functionality and promote meat tenderization. This study evaluated the application of alcalase in the preparation of cooked and salted chicken breast from WB chicken fillets. WB fillets were divided into two groups: an enzyme-treated and an untreated (control) group. Enzymetreated fillets had lower pH values, total and soluble collagen contents, collagen/protein ratio, and shear force than control. No changes in color, chemical composition, or water-holding capacity compared between groups was observed. After 2 days of storage, enzyme-treated fillets had lower lipid oxidation and total color change. Alcalase hydrolysis of WB fillets improved the tenderness and nutritional value of the cooked and salted chicken meat product. This strategy shows promise for minimizing economic losses caused by the WB myopathy.

Meat quality evaluation of breast fillets of different strains of chicken broilers with deep pectoral myopathy

“…Overall, it has been described that myopathy fillets have lower WHC than standard samples (Fig. S3), which leads to water losses during the processing and storage of the meat (Zago et al ., 2023). In this study, the WHC from the control sample was lower for Ross AP95 when compared to Cobb 500 ( P < 0.05).…”

“…Machine olfaction is a technology that enables gas detection by simulating the human olfactory system. It has been widely used and has shown significant advantages in scientific research fields such as gas composition analysis 8 VOLUME XX, 2017 [7], chemical analysis [8,9], agriculture [10,11], medicine [12], food [13][14][15], and criminal investigation [16]. In electrical equipment overheating detection, some scholars have used gas sensors combined with machine olfaction techniques to detect overheating of cables [17,18].…”
