The invention discloses margarine without trans-
fatty acid and a preparation method of the margarine without trans-
fatty acid. Considering total weight of the raw materials as 100 parts, the formula of the margarine without trans-
fatty acid comprises the following raw materials in parts by weight: 70-80 parts of 
grease gel, 15-20 parts of skim milk, 0.1-0.3 part of diglycerides, 0.05-0.20 part of 
phytosterol ester, 0.08-0.15 part of 
lecithin, 0.1-0.2 part of table salt, 0.02-0.04 part of 
citric acid, 0.007-0.01 part of 
EDTA calcium disodium and 0.05-0.2 part of 
potassium sorbate. The preparation method comprises the following steps: mixing the 
grease gel, the diglycerides, the 
phytosterol ester and the 
lecithin according to the ratio of the formula to obtain an 
oil phase; mixing the skim milk, the table salt, the 
citric acid, the 
EDTA calcium disodium and the 
potassium sorbate according to the ratio of the formula to obtain an aqueous phase; mixing the 
oil phase with the aqueous phase; then emulsifying, kneading and shaping the mixture to obtain the margarine without a trans-fatty acid product. The trans-fatty acid product is free of trans-fatty acid and 
cholesterol and is obviously reduced in 
saturated fatty acid content. Furthermore, the preparation method is simple in process.
