Blending oil is not the grade of oil, it is usually blended from more than two kinds of edible oils. Blended oils produced by various enterprises are mostly made by blending rapeseed salad oil, soybean salad oil, peanut oil and sesame oil according to 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 categories:

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 is the difference between refined oil/refined oil, high cooking oil, salad oil and blended oil?

Refined oil/refined oil is a customary saying, which is not clearly defined by the state. The refined oil/refined oil is usually between first-class oil and high cooking oil, and its quality is not stable enough.

High cooking oil and salad oil are processed on the basis of secondary oil and primary oil. Comparatively speaking, 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 better. It will not solidify when cooled below 0℃ for 5.5 hours.

Blended oil refers to two or more oils blended according to a certain proportion. At present, most blended 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.

5. What kind of oil has multiple nutritional functions?

Edible blending oil has many nutritional functions in oils and fats. Blending oil, as its name implies, is made by adding two or more oils in a certain proportion. Common blending oils are blended by rapeseed salad oil, soybean salad oil, peanut oil and sesame oil according to a certain proportion, which can develop strengths and avoid weaknesses, maintain nutrition and essential fatty acids, thus being beneficial to health. It has a mellow and delicious smell and taste on the taste, a compound aroma of peanut oil and sesame oil, and no smell of rapeseed oil, which can stimulate appetite.

6. From the health point of view, how to choose suitable edible oil?

Nutrition and health care experts point out that vegetable oils with high polyunsaturated fatty acids content, such as safflower seed oil, corn oil and sunflower seed oil, can reduce cholesterol in blood. Proper consumption (daily 1-3 tablespoons) is beneficial to heart patients, but excessive consumption can lead to some cancers and gallstones. Because polyunsaturated fatty acids are easily damaged by oxidation in the body, they may become the cause of some heart diseases and cancers.

Vegetable oils containing monounsaturated fatty acids, such as olive oil, rapeseed oil and tea seed oil, are mostly used as cooking oils. Among them, olive oil is the best, which will not only increase cholesterol in blood, but also increase high-density lipoprotein beneficial to human health.

7. Is the edible oil as clear as possible?

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 more clear and transparent it is. However, in the process of degumming, deacidification and desolvation, the harmful impurities such as aflatoxin are removed, and at the same time, the vitamins and other components beneficial to human body are also removed. If all impurities in the oil are removed, the refined oil at this time will no longer provide any nutrients to the human body like distilled pure water. Fulinmen refining edible oil process adopts long mixing technology. After eight-step refining, the impurities harmful to human body can be completely removed and the nutrients beneficial to human body can be effectively preserved.

8. Why is the liquid level height of the same specification oil different?

There are three reasons for the inconsistency of 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 is different from that of bottles produced later;

② Oil temperature: Temperature has a great influence on the volume of oil. This is because the density of oil changes obviously with the temperature. Generally, the higher the temperature, the smaller the density of oil, and the larger the corresponding volume, and vice versa. So the oil level line 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.

What is grease? What effect does oil have on human body?

Oil is a kind of natural organic compounds, and its chemical composition is a mixture of triglycerides. It, together with protein and carbohydrates, constitute the three major nutrients in nature.

The human body's intake of oil has four major functions:

1. provides heat for human body;

2. Provide essential fatty acids (linoleic acid, linolenic acid, etc.) that cannot be synthesized by human body but must be obtained from plant oil;

3. supply fat-soluble vitamins (VA, VD, VE, vk);

4. Provide food flavor and production function (baking oil, sesame oil flavor, etc.).
