Effect of Phospholipids on Storage Stability of Soybean Oil

The effect of phospholipids on storage stability of soybean oil at 65 ℃ was explored using first-grade soybean oil with different amounts of added phospholipids(2.5%,2.0%,1.5%,1.0%).The results indicated that the refractive index of soybean oil was increased during storage;phospholipids exhibited a little effect on the amount of acids;peroxide value and p-anisidine of high phospholipid content in soybean oil revealed slower growth,suggesting that phospholipids play a role in inhibiting oxidative rancidity.From the viewpoint of storage,the presence of phospholipids was beneficial to the storage of soybean oil.
