摘　　要：采用50%乙醇溶液从芡实种壳中得到一种提取物(ESE),采用HPLC-UV法对其中的酚类物质组成进行分析,并对其在肉制品保鲜方面的作用进行初步研究。结果表明:ESE中含有丰富的多酚物质,可定性的有没食子酸(364.11mg/g)、绿原酸(42.31mg/g)、表儿茶素(95.95mg/g)、表儿茶素没食子酸酯(3.16mg/g)和芦丁(129.21mg/g)。肉制品保鲜实验表明,单独添加ESE(500mg/kg),可以显著减轻猪肉乳化肠贮存期间的脂类氧化,但不能有效抑制产品pH值升高和改善产品颜色。将ESE、NaNO2和红曲粉进行适当复配,可以有效改善肉制品颜色、抑制其褪色,减轻脂类氧化,并延缓产品pH值升高。结果表明:这3者之间在抑制肉制品中微生物生长和脂类氧化方面存在一定的协同作用。Eruyaleferox is a kind of tonic food and its seed shell is the major by-product. One extract （Eruyale seed extract, ESE） was achieved from Eruyaleferox seed shell with 50% ethanol. The phenolic compounds in ESE were analyzed using HPLC-UV method, and the preservative effect of ESE on pork sausage product was also investigated in the present study. The results showed that ESE was rich in total phenols that were identified as gallic acid, chlorogenic acid, epicatechin, epicatechin gallate and rutin with concentrations of 364.11, 42.31, 95.95, 3.16 mg/g and 129.21 mg/g, respectively. Furthermore, the addition of ESE （500 mg/kg） into sausage alone, lipid oxidation during storage could be significantly inhibited, but the effects on pH and color of meat products were limited. The mixture of ESE, NaNO2 and red yeast rice at the appropriate ratios was added to sausage, the good and stable color of the products was achieved and notably inhibition of lipid oxidation during storage was observed. Therefore, ESE, NaNO2 and red yeast rice can reveal a synergistic effect on the inhibition of microbial growth and lipid oxidation in sausage products.
