    Abstract:
    This study investigated the effects of non-phosphate and low-sodium (NPLS) marination on properties of white striping chicken breasts (WSCB). Chicken breasts were collected from slaughterhouse and classified as normal (NCB, n = 24) and severe WS (WSCB, n = 120). Sixty WSCB samples were vacuum-tumbled (30 min, 2 °C) with NPLS solution, containing 2.8% (w/v) potassium bicarbonate, 2.9% (w/v) potassium chloride, and 1.5% (w/v) sorbitol at the ratio of meat-to-marinade of 4 to 1 (w/w). The other 60 WSCB received no marination were assigned as nonmarinated WSCB. Properties of marinated (n = 12) and nonmarinated (n = 12) WSCB samples were determined at 0, 3, 7, 10, and 14 days of the storage at 4 °C. Properties of the NCB were also determined on day 0. Concerning day 0, the marinated WSCB exhibited higher (p < 0.05) pH, moisture content, total cooked yield, protein solubility, hardness, cohesiveness, and chewiness along with lower (p < 0.05) cooked loss, expressible water, and shear force than those of nonmarinated WSCB and NCB. Based on nuclear magnetic resonance spectroscopy, bound, intra-myofibrillar, and extra-myofibrillar water of cooked marinated WSCB were greater (p < 0.05) than those of cooked nonmarinated WSCB. The greater (p < 0.05) weight loss, moisture content, and total cooking yield were observed in marinated samples compared to those of nonmarinated WSCB throughout the storage period. Although microbial stability was reduced (p < 0.05), no difference (p ≥ 0.05) in lipid oxidation was detected between the treatments. The findings suggest the NPLS marination as a promising process for improving water holding capacity of the WSCB. PRACTICAL APPLICATION: This study presents the promising application of non-phosphate, low-sodium (NPLS) marination combined with vacuum-tumbling in improving water holding capacity of chicken breast meat affected with white striping condition. Although microbial stability of the marinated breast was negatively affected, no adverse impacts on lipid oxidation was observed during storage up to 14 days.
