Abstract

The invention discloses a refining method for medicinal sucrose. The refining method comprises the following concrete steps: juicing of sucrose, pre-filtration, pre-concentration, decoloring with activated carbon, re-filtering, impurity removal via a semi-permeable membrane, purification and crystallization, centrifugation, drying, etc. The refining method has the advantages that an activated carbon process is employed for decoloring, so production cost is greatly reduced compared with an ion exchange decoloring process, the problem of residual sulfur in sucrose produced by using a sulfur fumigation process is avoided, and product quality is improved; a semi-permeable membrane process is employed for impurity removal, so impurities in sucrose can be effectively removed; and through subsequent purification and ultrasonic crystallization, the prepared medicinal sucrose reaches standards prescribed in Chinese Pharmacopeia and meets medicinal requirements, the particle size of the sucroseis controlled in a range of 30 to 100 nm, and the prepared medicinal sucrose has moisture resistance and hygroscopicity.

Description

technical field [0001] The invention relates to a method for refining sucrose, which belongs to the field of medicine and chemical industry. Background technique [0002] Sucrose is a kind of carbohydrate, which widely exists in sugarcane, beet, fruit, etc. The sucrose we eat daily is mainly made from sugarcane and beet. The sucrose molecule is produced through the photosynthesis of plants and is a natural food. . [0003] Sucrose has a history of thousands of years. According to the "History of Sucrose", China's sugar production technology has reached the world's top level in the Tang Dynasty. The so-called "one-step method" usually refers to the on-site processing of sugar materials (sugar cane, sugar beet) in the field sugar factory in the sugar production area to directly produce refined sugar, that is, "farmland sugar"; including: cultivated land white sugar, cultivated land Brown sugar, cultivated brown sugar, etc. The sugar produced by the "one-step method" can be ...
