摘要: 用热水浸提法提取了安徽宁国山核桃的外果皮色素,同时对其外观、颜色,溶解性,光谱特性,稳定性等性质进行了研究,结果表明宁国山核桃的外果皮色素呈酒红色,是一种混合物,溶解性良好,对光的稳定性稍差,但对温度、乙醇、食盐、蔗糖等的稳定性较好。宁国山核桃的外果皮色素是一类有较好应用前景的食用色素。

Abstract: The pigment of walnut (Ningguo, Anhui Province) outer peel was extracted by the means of soaking in hot water. Meanwhile its outward, color, solution, light spectrum characteristics and stability were studied. The result indicated that the pigment of walnut outer peel is a wine-red mixture and well dissolved. The pigment is unstable under light but has a good stability for temperature, alcohol, salt and sucrose. Thus the pigment of walnut outer peel has a good prospect as an edible pigment.
