Abstract

The invention relates to a lipid emulsion with a low anisidine value, which contains oily constituents, water, an emulsifying agent and an osmotic pressure regulator, wherein the lipid emulsion contains a metal ion chelant but not an antioxidant. The content of the metal ion chelant is below 100mg/ml. The metal ion chelant is one or more of sodium calcium edentate, edetate disodium, edetate sodium and edetic acid. The invention relates to a method for preparing the lipid emulsion with the low anisidine value as well. According to the invention, in the process of preparing the lipid emulsion, other antioxidants are not needed to add, such as Vitamin E (VE), the antioxidation can be implemented only by using the metal ion chelant, and the low anisidine value can be greatly reduced. The low anisidine value of the lipid emulsion cannot be reduced by adding other antioxidants.

Description

technical field [0001] The invention relates to a fat emulsion with low methoxyaniline value and a preparation method thereof. Background technique [0002] Fat emulsions for intravenous injection are mainly oil-in-water emulsions made by emulsifying an oil phase, such as soybean oil, medium-chain triglycerides, and an aqueous phase. Among them, the oil phase components contain unsaturated bonds, which are easily oxidized and converted into peroxides. The methoxyaniline value is an index reflecting the decomposition of peroxides into aldehydes and ketones. If the value is high, it may damage the liver function of the human body. In order to further strengthen the quality control of emulsion products, it is necessary to increase the control of the value of methoxyaniline in fat emulsions, in order to expect to strengthen the quality control of emulsions. The existing technology is mainly to avoid the occurrence of oxidation by strictly filling the whole process with nitroge...
