Abstract： As an important edible oil raw material， the relationship between structural modification and physicochemical properties of soybean oil has atracted much attention. This article systematically elaborates on the principles and characteristics of three types of structural modification methods： chemical， enzymatic，and physical.Fromtheaspects of melting point，freezing point，oxidationstabilityetc.，itdeeplyanalyzestheimpactand mechanism of structural modification on the physicochemical properties of soybean oil. Research has shown that by regulating the composition of faty acids，triglyceride structure，and trace components，the melting characteristics， antioxidant properties，and crystaline polymorphismof soybean oil can be significantly changed.This not only helps to broaden the application fieldsofsoybean oil and enhance its added value，butalso providesa theoretical basis for the development of new structural fats.

Keywords： soybean oil; structural modification; physical and chemical properties
