Blending oil is not the grade of oil, but is generally made by blending more than two kinds of edible oils. The blended oil produced by various enterprises is mostly made of rapeseed salad oil, soybean salad oil, peanut oil and sesame oil in a certain proportion.
2. According to the variety of oil:
1, animal fat
2. Vegetable oils: soybean oil, rapeseed oil, peanut oil, blended oil, sesame oil, corn oil, safflower seed oil, etc.
3. According to fatty acid category:
1, saturated fatty acid oil: animal oil;
2. Monounsaturated fatty acid oils: rapeseed oil, olive oil, etc. ;
3. Polyunsaturated fatty acid oils: sunflower seed oil, soybean oil, corn oil, etc.
4. What's the difference between refined oil/refined oil, high cooking oil, salad oil and blended oil?
Refined oil/refined oil is a conventional saying, and there is no clear definition in the country. Refined oil/refined oil is usually between first-class oil and high cooking oil, and its quality is not stable enough.
Advanced edible oil and salad oil are processed on the basis of secondary oil and primary oil. Comparatively, salad oil is more advanced than high cooking oil. The smoke point of salad oil is higher than that of high cooking oil. Salad oil is slightly lighter in color and smells more fragrant. Cooling below 0℃ for 5.5 hours will not solidify.
Blending oil refers to the mixture of two or more oils in a certain proportion. At present, most blending oils on the market are blended with rapeseed salad oil, soybean salad oil, peanut oil and sesame oil, which are not only delicious, but also comprehensive in nutrition.
Many people have such a misunderstanding when eating oil, that is, the clearer the oil, the higher the quality, and the more beneficial it is to human health. In fact, this idea is one-sided.
The higher the refining degree of edible oil, the clearer and more transparent it is. However, in the process of degumming, deacidification and desolvation, harmful impurities such as aflatoxin are removed, and vitamins and other components beneficial to human body are also removed. If all the impurities in the oil are removed, the refined oil will no longer provide any nutrition to the human body like distilled pure water. Fulinmen refining edible oil process adopts long mixing technology. After eight steps of refining, impurities harmful to human body can be completely removed, and nutrients beneficial to human body can be effectively retained.
8. Why is the liquid level height of oil of the same specification different?
There are three reasons for the inconsistency of the filling oil level line:
① There are differences in the volume of packaging containers: for example, the volume of PET bottles will decrease under certain temperature conditions, so the volume of bottles produced first and those produced later is different;
② Oil temperature: Temperature has a great influence on the volume of oil. This is because the density of oil changes obviously with temperature. Generally, the higher the temperature, the smaller the density of oil and the larger the corresponding volume, and vice versa. Therefore, the oil level produced in winter is definitely different from that produced in summer.
③ Filling accuracy: Due to continuous production, different bottles of oil are filled by different filling heads. Different filling heads have different filling accuracy.
