【摘要】：对不同性别美国野山鸡肌肉色泽和系水性之间的相关性进行研究和比较分析。选择120 d健康,体重无明显差异的美国野山鸡24只(公母各12只),取胸肌和腿肌样,分析宰后和冷藏48 min、24 h、48 h和72 h时的色泽、含水率和系水性指标并进行相关性分析。结果表明,公野山鸡胸肌亮度(L*)和黄度(b*)与解冻损失率和失水率间存在显著(P0.05或P0.01)正相关,而腿肌48 min和48 h的L*与水浴损失间显著(P0.05)负相关;母野山鸡腿肌48 min、48 h和72 h的L*与解冻损失率和含水率间显著(P0.05或P0.01)正相关,而红度(a*)与其存在显著(P0.05)负相关,且48 h后的腿肌a*和b*与滴水损失率间显著(P0.05)正相关。综上所述,美国野山鸡肌肉色泽和系水性之间存在明显的相关性,且与其性别、部位和宰后时间密切相关。
[Abstract]:The correlation between muscle color and water quality of American wild pheasant was studied and compared. Twenty-four American wild pheasants with no significant difference in body weight were selected for 120 days. Breast muscle and leg muscle samples were taken to analyze the color, moisture content and water content of postmortem and cold storage for 48 min,24 h and 72 h, and the correlation analysis was carried out. The results showed that there was a significant positive correlation between breast muscle brightness (L *) and yellowness (b *) and thawing loss rate and water loss rate (P 0.05 or P 0.01), while 48 min and 48 h L * of leg muscle were negatively correlated with water bath loss. There was a significant positive correlation between leg muscle L * and thawing loss rate and moisture content at 48 min,48 h and 72 h in female wild pheasant (P 0.05 or P 0.01), but a significant negative correlation between redness (a *) and leg muscle loss rate (P 0.05), and a significant positive correlation between leg muscle a * and b * and drip loss rate 48 h later (P 0.05). To sum up, there is an obvious correlation between muscle color and line water in American wild pheasant, and it is closely related to its sex, location and postmortem time.
