葡萄酒中主要矿质元素的研究

Study on the main mineral elements in wine

对葡萄酒酿造过程中的矿质元素进行了系统的研究。结果表明,果皮中矿质元素的含量要高于果肉中的。在酿酒过程中,所有矿质元素的含量都在发生变化:K、Ca、Na、Mg、Fe的含量有所上升,但是Cu、Zn含量稍有下降。不同矿质元素的含量因产区、种类及年份而不同。

Mineral elements during winemaking were studied systematically. The results showed that the content of mineral elements in grape skin was higher than in the pulp. The content of all mineral elements varied during winemaking, in which, contents of potassium、calcium、sodium、magnesium、iron increased, but contents of copper and zinc decreased slightly. The content of mineral elements varied with different production regions, cultivars and vintage.
