使用绿色植物的叶制造含有叶绿素的粉末,作为食品营养添加剂使用正在兴起。本文重点介绍用萝卜叶来生产含有叶绿素的天然色素的方法。其主要工艺流程为:原料拣选→洗净→浸泡→冷冻→解冻→脱水→水洗→脱水、烘干→粉碎→过筛→成品。原料及处理原料要选择绿色的萝卜叶,剔去干枯的黄叶,漂洗干净后沥干、称重。浸泡液配制和浸泡(1)配制浸泡液:1%氯化钠和l%小苏打混合液。(2)浸泡:将洗净沥干的萝卜叶,加入浸泡液中,并用竹垫压住萝卜叶,使萝卜 The use of green plant leaves to produce powders containing chlorophyll is emerging as a nutritional additive for foods. This article focuses on the use of radish leaves to produce natural pigments containing chlorophyll. The main technological process is: raw material selection → washing → soaking → freezing → thawing → dehydration → washing → dehydration, drying → smashing → sieving → finished products. Raw materials and raw materials for processing should be selected from the green radish leaves, and the dried yellow leaves should be removed, rinsed, drained, and weighed. Soaking solution preparation and soaking (1) Preparation soaking solution: 1% sodium chloride and 1% soda mixture. (2) soaking: Wash and drain the radish leaves, add the soaking solution, and press the radish leaves with a bamboo mat to make the radish
