Canola oil pressing and leaching are two different processing methods, each with its own advantages and disadvantages, and which is better depends on the individual's needs and preferences.
Crushing is a traditional method of oil production, usually using low temperature and physical methods to separate the oil from the raw material. No chemical solvents are used during the pressing process, so the oil is naturally pure, relatively high in nutrients and has a natural aroma. However, the oil yield of the press method is relatively low and requires a lot of labor to operate.
Leaching is a modern method of oil production, usually using organic solvents or water to extract the oil from the oil. The leaching method has a high oil yield, low processing cost, and good production conditions. However, chemical solvents are used in the leaching process, and while the oil has been scientifically treated to meet the food standards, some people are still concerned about the impact that residual solvents may have on the oil.
From a nutritional point of view, pressed oil can better retain the original nutrients of oil crops, such as vitamins, minerals, trace elements, etc., as well as the original natural flavor of plants. And leaching oil may destroy some of the nutrients and natural flavor. As a result, pressed canola oil may be more popular for people who are concerned about nutrition and taste.
In addition, pressed oils usually do not contain chemical solvent residues, so they are considered to be more natural and healthy oils. However, chemical solvents or other harmful substances may remain in the leaching oil, although it meets the food standards, it is still necessary to choose carefully.
In summary, for rapeseed oil processing methods, pressing and leaching have their own advantages and disadvantages. If you are concerned about nutrition and taste, and prefer natural and pure oils, you can choose pressed canola oil. If you're more concerned about oil yield and processing costs, and don't have particular concerns about chemical residues, you can opt for canola oil leaching.
No matter which processing method you choose, you need to pay attention to choosing regular channels to ensure the freshness and quality of the oil. In addition, correct storage and cooking methods are also important factors in ensuring the nutritional value and taste of rapeseed oil. When storing rapeseed oil, it should be kept away from direct sunlight and high temperatures, and should be kept in a cool and ventilated place as much as possible. When cooking, you should choose the right oil and oil use method according to different cooking needs to make full use of the nutritional value and flavor of rapeseed oil.
Finally, it should be pointed out that for any kind of food processing method, it needs to be selected according to the actual situation and individual needs. When choosing the processing method of rapeseed oil, you can choose the most suitable processing method according to your preferences and needs.
