关于海带所含主要化学成分的季节变化,国外自1938年以来已有若干研究报道发表,在我国年来对于大连产及青岛产海带所含主要化学成分的季节变化也开始进行了较有系统的分析工作,这一作,对于海带的食用、工业利用和生理生化的研究,都是很有意义的。我国人工培育的一年生海带,由分苗期的不同,分夏苗和秋苗两种,在三月间,秋苗仅长50余厘米,而夏苗已长一米多,其化学成分的长可能也有所不同。本文仅就海带秋苗的水分、灰分、碘、褐藻酸和粗蛋白含量的季节变化进行了分析。
As for the seasonal changes of the main chemical components contained in kelp, several studies have been published in foreign countries since 1938. In the past years, the seasonal changes in the major chemical components contained in kelp produced in Dalian and Qingdao have also been systematically analyzed Work, this work, for kelp edible, industrial use and physiological and biochemical research, are of great significance. The annual kelp cultivated by our country is divided into two types: summer seedling and autumn seedling by dividing the seedling stage. In March, autumn seedling is only 50 centimeters longer, while the summer seedling is more than one meter long. The length of its chemical composition It may be different. In this paper, we only analyzed the seasonal changes of moisture, ash, iodine, alginic acid and crude protein content in autumn leave of kelp.
