Standards and Practices for Purchasing Quality Oils.
In daily life, oil is one of the important ingredients for our cooking. However, among the many oil products, how to choose high-quality, healthy oil has become a difficult problem for many consumers. This article will break down the criteria for buying high-quality oil to help you make an informed choice.
1. Understand the types and characteristics of oil.
At present, the common edible oils on the market mainly include rapeseed oil, cottonseed oil, sunflower oil, camellia seed oil, corn oil, rice bran oil, etc. Different kinds of oils have different fatty acid compositions and nutritional properties. For example, sunflower oil and corn oil are rich in unsaturated fatty acids, which have a positive effect on lowering cholesterol and preventing cardiovascular diseaseTea seed oil, on the other hand, has high antioxidant properties. Therefore, when choosing an oil, we must first understand its types and characteristics, and choose the right oil according to our own needs.
Second, pay attention to the production process of oil.
The process in which oil is made has an important impact on its quality and taste. Traditional physical pressing process and modern chemical leaching method are the two main methods of oil production. The physical pressing process extracts the oil through physical extrusion, which retains the natural nutrients and pure taste in the oilThe chemical leaching method extracts the oil from the oil through organic solvents, which has a high oil yield but may lead to the loss of some nutrients. When purchasing, you can pay attention to the manufacturing process information on the product label and choose the oil that meets your needs.
3. Check product labels and certifications.
When buying a high-quality oil, carefully check the information on the product label. According to the "National Food Safety Standard General Principles for Prepackaged Food Labeling" and "National Food Safety Standard Vegetable Oil" and other relevant regulations, the label of prepackaged edible vegetable oil should contain the name of the food, the list of ingredients, the net content and specifications, the name of the producer and/or the distributor, the address and the production date and shelf life, storage conditions, food production license number, product standard code and other content. If the quality level is specified in the product implementation standard, the quality level should also be indicated. In addition, you can pay attention to whether the oil has obtained relevant certifications, such as green food certification, organic food certification, etc., which can ensure the quality and safety of oil products to a certain extent.
Fourth, pay attention to the storage and use of oil.
After purchasing high-quality oil, proper storage and use are equally important. The oil should be stored in a cool, dry and dark place to avoid oxidation and deterioration caused by high temperature and direct sunlight. At the same time, the oil temperature should be controlled when using to avoid excessive temperature destroying the nutrients in the oil and producing harmful substances.
In short, when buying high-quality oil, we should pay attention to the type and characteristics of the oil, the manufacturing process, product labeling and certification, and storage and use. By understanding and mastering this knowledge, we can better choose the right high-quality oil for ourselves and provide a healthy diet for our family.
