1, lard:
(1) Fatty acid composition
Saturated fatty acids: 42%.
Unit unsaturated fatty acid: 48%.
Polyunsaturated fatty acids: 10%.
(2) Expert analysis: Eating too much, the body's cholesterol is easy to increase, easily lead to cardiovascular disease, but can be used for a long time high temperature cooking.
2. Soybean oil (salad oil):
(1) Fatty acid composition
Saturated fatty acids: 15%.
Unit unsaturated fatty acid: 24%.
Polyunsaturated fatty acids: 61%.
(2) Expert analysis is rich in lecithin and carotene. However, it is not suitable for high-temperature oil pressing, low smoke point (180°C) is easy to produce soot, and many antioxidants must be added when refining.
3, rapeseed oil:
(1) Fatty acid composition
Saturated fatty acids: 6%.
Unit unsaturated fatty acid: 58%.
Polyunsaturated fatty acids: 36%.
(2) Expert analysis: Because of containing higher unsaturated fatty acids, cardiovascular disease can be reduced. However, high erucic acid requires refined deacidification and poor stability.
4, olive oil:

Saturated fatty acids 14%.
Unit unsaturated fatty acid: 29%.
Polyunsaturated fatty acid: 57%.
(2) Expert analysis contains rich vitamins E and F, which can lower blood cholesterol, increase metabolism, have anti-oxidation, high temperature fuming point up to 245°C, and still contain lecithin and tocopherol as a high grade edible oil. .
6, peanut oil:
(1) Fatty acid composition
Saturated fatty acids: 21%.
Unit unsaturated fatty acid: 49%.
Polyunsaturated fatty acids: 30%.
(2) Expert analysis: Because peanut oil contains a special flavor and flavor, there is a certain favorite consumer group, for the average fatty acid composition, the oil is relatively stable for high temperature frying.
7, sesame oil:
(1) Fatty acid composition
Saturated fatty acids 16%.
Unit unsaturated fatty acid: 54%.
Polyunsaturated fatty acids: 30%.
(2) Expert analysis Since ancient times, sesame oil has been indispensable for cooking in the country. It differs from other oil products in that sesame oil contains more antioxidants, such as vitamins and sesameol, which are beneficial to human health. It is best not to cook sesame oil at high temperature, and the lower smoke point of sesame oil is not suitable for cooking.
