Extended data:
Mass of two oils
First of all, the quality of both oils is good. As long as we directly extract oil from peanuts or rapeseed without adding any additives, these oils taste particularly fragrant and can be safely eaten, because the crops we grow are also squeezed by ourselves and can be safely eaten.
The appearance of two oils
If you look at the appearance of the two oils, there will be a little difference. From the appearance, peanut oil belongs to the yellow and shiny kind and looks very transparent. Therefore, when frying vegetables with important colors and appearances, we often choose peanut oil, which will largely keep the best-selling vegetables, such as shredded potatoes and green vegetables.
However, rapeseed oil is somewhat different. The oil extracted from rapeseed looks slightly black, and some are black. Therefore, many people will misunderstand rapeseed oil because of the color problem, and think that rapeseed oil is not as good as peanut oil. In fact, authentic rapeseed oil is like this. Therefore, rapeseed oil is mostly used for fried meat or stew. Of course, rapeseed oil is also very suitable for frying. The food fried with rapeseed is golden yellow and beautiful.
What kind of stir-fry is more fragrant?
In fact, if two kinds of oil are squeezed by themselves, then no matter which one tastes good. Because these two oils come from different crops, they taste slightly different. Peanut oil is more fragrant, so it has more advantages when cooking and is also suitable for making cakes. This kind of cake smells delicious.
Rapeseed oil also has its own unique advantages. The fried things are attractive in color. The cholesterol content of rapeseed oil is lower than that of peanut oil, which is very suitable for people with high cholesterol. Moreover, the nutritional value of rapeseed oil is comparable to that of olive oil. Therefore, the two oils have their own advantages, and everyone can safely eat them.
Peanut oil contains more minerals. According to the determination, peanut oil and rapeseed oil both contain 9 minerals such as sodium, magnesium, phosphorus, potassium, calcium, manganese and iron, but the content of peanut oil is slightly higher than that of rapeseed oil.
Rapeseed oil contains more unsaturated fatty acids. According to the determination, peanut oil contains 39g monounsaturated fatty acids, 36.6g polyunsaturated fatty acids, 56.2g monounsaturated fatty acids and 23.7g polyunsaturated fatty acids per kloc-0/00g. Compared with the two, rapeseed oil contains more unsaturated fatty acids as a whole.
After all, rapeseed oil and peanut oil are edible oils extracted from two different plants, so there will still be obvious differences in composition between them. Through the comparison of the above data, it can be found that the unsaturated fatty acids in rapeseed oil are obviously higher than those in peanut oil, especially monounsaturated fatty acids, which are about100g higher than those in peanut oil;
Cooking oil with higher unsaturated fatty acids is more nutritious, but it will not be very heat-resistant when cooking (because cooking oil with higher unsaturated fatty acids is more unstable and heat-resistant). So if you buy it for cooking, rapeseed oil is not suitable. On the contrary, peanut oil will be more stable and more suitable for frying. If it is mainly cooking, peanut oil and rapeseed oil will be more useful, and there is no obvious difference between them.
Peanut oil has a good proportion of fatty acids, which is beneficial to human digestion and absorption. According to foreign data, the use of peanut oil can decompose cholesterol in human body into bile acid and excrete it, thus reducing the cholesterol content in plasma.
Peanut oil also contains wheat germ powder, phospholipids, vitamin E and other substances beneficial to human body. Regular consumption of peanut oil can prevent chapped skin, vascular aging, thrombosis, arteriosclerosis and coronary heart disease. Choline in peanut oil can also improve the memory of human brain and delay the decline of brain function.
Rapeseed oil is generally dark yellow or brown. Rapeseed oil contains arachidonic acid 0.4% ~ 1%, oil/kloc-0.4% ~/kloc-0.9% and linoleic acid/kloc-0.2% ~ 24%. In terms of nutritional value, the digestibility of rapeseed oil can be as high as 99%, which is beneficial to bile function. When the liver is in a pathological state, rapeseed oil can also be normally metabolized by the human body.
Rapeseed oil lacks essential fatty acids such as linoleic acid, and its fatty acid composition is unbalanced, and its nutritional value is lower than that of ordinary vegetable oil.
Rapeseed oil contains a lot of erucic acid and glucosinolates, which is generally considered to be unfavorable to human growth and development. If it can be eaten with high-quality edible oil rich in sulfurous acid, its nutritional value will be improved.
Peanut oil is made from peanuts and is rich in unsaturated fatty acids. Proper consumption of peanut oil can reduce cholesterol, increase appetite, promote growth and development, delay aging and improve memory.
1. Lowering cholesterol: The fatty acid composition of peanut oil is reasonable, which is easy for human body to digest and absorb, which is conducive to the decomposition of cholesterol into bile acids and excretion, and can reduce the cholesterol content in plasma;
2, improve appetite and promote growth and development: peanut oil contains a variety of minerals needed by the human body. The content of zinc is several times that of salad oil, corn oil, rapeseed oil and soybean oil. Zinc supplementation can promote appetite, which is beneficial to the growth and development of children and the health of adults.
3, delay aging and improve memory: peanut oil contains phospholipids, vitamin E, choline and other nutrients, which have a certain effect on relieving fatigue, delaying aging and improving memory. Peanut oil contains phytochemicals, such as resveratrol, maltol, β -sitosterol and so on, which is beneficial to the cardiovascular and cerebrovascular health of the elderly.
Although peanut oil has high nutritional value, it has high energy density and belongs to high-energy food. It should be taken in moderation, and it is recommended not to exceed 25g per day. Excessive intake can easily lead to excess energy and obesity, thus increasing the risk of chronic diseases.
