Cow milk lactoferrin content checking method

Abstract

The invention relates to a method for detecting the compositions of the milk, in particular to a method for detecting the content of lactoferrin, belonging to the detection technical field. The method for detecting the content of lactoferrin by a capillary electrophoresis apparatus comprises the following steps of pretreatment of a sample, the sample detection, the calibration and reading, and the edition and report, etc. The electrophoresis is passed through the sample by the capillary electrophoresis apparatus, thereby detecting the absorbance value of the sample by the capillary electrophoresis apparatus, displaying the absorbance value in a form of map, detecting the content of lactoferrin accurately and providing the technical support for the product research, the quality control and the component analysis.

Description

technical field

[0001] The invention relates to a method for analyzing and detecting protein in milk, in particular to a method for detecting lactoferrin content in milk. It belongs to the technical field of detection. Background technique

[0002] Lactoferrin is a glycoprotein with a molecular weight of 70-80kD, which is widely present in milk, saliva, tears and other exocrine fluids, plasma, and neutrophils. The content of lactoferrin in milk is 0.7g / L. Lactoferrin is a multifunctional protein with broad-spectrum antibacterial and antiviral infection effects, and can regulate the balance of iron in the body; regulate the production of bone marrow cells and promote cell growth; regulate the body's immune function and enhance the body's disease resistance; inhibit The role of human tumor cells; it can work synergistically with a variety of antibiotics and antifungal agents to treat diseases more effectively.
