    • PURPOSE: A manufacturing method of jujube origin pectin is provided to effectively extract pectin from a jujube. CONSTITUTION: A jujube origin pectin production method comprises the following steps: a step which treats freeze-dried jujube with hemicellulase; a step which extracts supernatants by extracting the jujube at 60-70 deg. C for 1-3 hours by centrifuging after adjusting in the pH into 0.5-1.5, and adding acid in the jujube which is treated with hemicellulase; and a step which precipitates pectin by adding isopropyl alcohol in the supernatants. The treatment of hemicellulase is executed for 4 hours at 70 deg. C. The isopropyl alcohol is added in a weight ratio of 1:3. The jujube origin pectin has 20-40 mol% methylation degree and 1-5 mol% of acetylation degree, and the contents of galacturonic acid is 40-60 mol%.
    • 目的:提供枣原果胶的制造方法,有效地从枣中提取果胶。 构成:枣原果胶生产方法包括以下步骤:用半纤维素酶处理冷冻干枣的步骤; 通过在60-70度提取枣来提取上清液的步骤。 在pH调节至0.5-1.5之后通过离心分离1-3小时,并在用半纤维素酶处理的枣中加入酸; 以及通过在上清液中加入异丙醇而使果胶沉淀的步骤。 半纤维素酶的处理在70度下进行4小时。 C.异丙醇以1:3的重量比加入。 枣原果胶具有20-40mol%甲基化度和1-5mol%乙酰化度,半乳糖醛酸含量为40-60mol%。
