Abstract

The invention discloses a decolorizer for reducing an anisidine value in soybean oil for injection and a method for preparing the same. According to the mass percentage, modified attapulgite is mixed with 2 to 3 percent of carbonized bean husk ash to prepare the decolorizer; and the method comprises the following steps: 1, purifying the attapulgite; 2, activating the attapulgite; 3, modifying the attapulgite; 4, preparing the carbonized bean husk ash; and 5, according to the mass ratio of 97-98:2-3, mixing the modified attapulgite with the carbonized bean husk ash in a stirring tank, and grinding the mixture by a pulverizer to obtain the decolorizer. The decolorizer prepared by the method has the advantages of quick decolorizing speed and good decolorizing effect.

Description

technical field [0001] The invention relates to a decolorizing agent and a preparation method thereof, in particular to a decolorizing agent for reducing the anisidine value of soybean oil for injection and a preparation method thereof. Background technique [0002] Soybean oil for injection is a light yellow clear liquid with a weak and specific smell, light taste, slightly soluble in ethanol, and can be mixed with ether, chloroform or petroleum ether arbitrarily. It can be used as injection or intravenous fat emulsion raw material. Fat emulsion infusion is a concentrated high-energy parenteral rehydration solution, which can be used for intravenous injection and can be completely metabolized and utilized by the body. It is mainly used for patients who have difficulty eating before and after surgery and severe It is a kind of high-calorie and nutrient-rich natural vegetable oil that has important physiological functions for the human body. The oil contains a variety of esse...
