The standard of living has increased, from bulk oil 10 years ago to the small packaged edible oil that is increasingly accepted by people today, from the joint use of animal and vegetable oils to today's complete vegetable oils. It shows that people's consumption habits of edible oils are gradually developing to high standards. However, due to the continuous innovation of edible oil varieties, people's understanding of edible oil is often detached from the inside and outside of the consumption error.
Edible oil, as its name suggests, is an oil product for human consumption. Mainly used for cooking, frying, frying, fried foods and so on.
Seen from the source of oil, edible oil can be divided into vegetable oil and animal oil. According to raw materials, vegetable oil can be divided into: soybean oil, rapeseed oil, peanut oil, sesame sesame oil, corn germ tooth oil, sunflower oil and so on.
According to the degree of refinement, the edible oils from the low grade to the high grade can be divided into the secondary oil, the primary oil, the high cooking oil, and the salad oil. Now people's major edible oils have reached the level of salad oil. What are the characteristics of salad oil and other less refined edible oils?
Salad oil is to remove the impurities and harmful substances contained in the food gradually and retain the nutrients through eight processes such as deacidification, desolvation, deodorization, dehydration, decoloration, degumming, dewaxing and decontamination. While some of the less refined edible oils contain more impurities, more or less negative impact on the human body, so salad oil has become the mainstream of edible oil.
As an essential dietary composition, edible oil has a profound impact on human health. Therefore, the nutritional value of edible oil has become an important reference factor for people to choose edible oils. In fact, the introduction of various nutritive oils in recent years also illustrates this point.
