Pay attention when buying oil, don't just look at the brand and price, there is this line on the package, it is a good quality oil
People who know how to buy oil, look at the words on the package and then buy no matter what brand, it is all high-quality and good oil
Vegetable oil is used almost every day for food, whether frying, frying or salad, making all kinds of delicious dishes, all kinds of vegetable oils are inseparable. There are many kinds of vegetable oils in supermarkets, such as peanut oil, soybean oil, rice oil, sunflower oil, rapeseed oil, linseed oil, olive oil, etc. There are many kinds, many brands, and different prices. People are so confused that they don't know what to choose.
Today, let’s talk about how to choose vegetable oil. When buying oil, pay attention to it. Don’t just look at the brand and price. Those with this line on the package are high-quality and good oils.
Vegetable oil is made from oil-rich seed kernels. After pretreatment such as cleaning, removing impurities, shelling, crushing, softening, rolling, and extrusion, crude oil is obtained by mechanical pressing or solvent leaching. Obtained after refining.
China's national standard stipulates that according to the quality and processing technology of edible oil, general edible oil is divided into 4 grades, namely grade one, grade two, grade three and grade four, such as soybean oil, rapeseed oil, corn oil, sunflower oil, etc. Seed oil, leached peanut oil, leached rapeseed oil, etc.; and the pressed peanut oil, pressed camellia seed oil and sesame oil, etc., only have one or two grades.
The higher the grade of vegetable oil, the higher the nutritional value, because the higher the grade, the higher the degree of refining, the higher the purity of the oil and the less impurities, but some nutrients will be lost. For example, the carotene of soybean oil will be lost during decolorization. However, relatively speaking, oils with high grades have a high smoke point, and oils with low grades have low smoke points. They are not suitable for high-temperature frying and frying, and are only suitable for low-temperature cooking.
- Ingredients list
According to the relevant regulations of the state, if it is a genetically modified product, it must be clearly marked on the outer packaging or instructions. Everyone should try to choose non-GMO edible oil. Genetically modified food has been controversial, and it has not been proved that it is harmless to the human body. Therefore, it is not recommended for everyone to buy it. Genetically modified cooking oil.
There are usually 2 forms of vegetable oil processing, pressing and leaching
The pressing method is divided into cold pressing and hot pressing. It is relatively simple. The oil is directly separated from the raw material by physical pressure, without chemical additives, so it is safer and more secure, and the nutritional value will not be damaged. The disadvantage is that the shelf life will be shorter.
The leaching method is much more complicated. The raw materials are dissolved in solvent oil to form a mixed oil, which is then made by a series of processing techniques such as degreasing, degumming, dehydration, decolorization, deodorization, and deacidification. The leaching method has high oil yield and low production cost, but the leaching oil may have some chemical residues left, and the nutrients in the oil will be destroyed.
Another method is pre-pressing leaching, that is, the raw materials are first pressed, and then the pressed residue is leached by leaching, and then mixed.
From the perspective of nutritional content and health, it is recommended that you buy vegetable oil produced by pressing.
- Nutrients
In the nutrient composition table, we mainly look at these indicators. One is the data of fat and vitamins. These two must be high in content, and the higher the nutritional content. The second is the content of cholesterol and sodium. These two data should be 0. .
- Production date and shelf life
Different production techniques and varieties of vegetable oils have different shelf lives, but no matter which oil, you must buy the one with a relatively recent production date, so that it can be stored for a longer time. In addition, vegetable oil should be stored in a cool and ventilated place, not in a place with high temperature.
Pure oil refers to vegetable oil processed from a single variety of raw materials. The country has relevant implementation standards. It is not allowed to add flavors or other spices to these oils.
Blended oil is prepared by mixing different pure oils according to the proportion, and you can eat different kinds of oils at the same time, but the proportion of several oils in blended oil is usually not clear, and some blended oils will also contain additives such as essence.
Therefore, it is recommended that you eat as little blended oil as possible. You can use one pure oil before changing to another.
Daily frying oil: peanut oil, soybean oil, rapeseed oil, corn oil, rice oil, etc.
Daily salad oil: sesame oil, olive oil, linseed oil, etc.
Western cooking oil, baking oil: butter, palm oil, coconut oil, butter, etc.
The types of fatty acids contained in each pure oil are different, and they should be eaten frequently to absorb different nutrients.
The "Dietary Guidelines for Chinese Residents" recommends that residents consume 25-35 grams of edible oil a day, which is a relatively healthy standard.
Now to sum up, when buying oil, you should choose non-GMO edible oil, choose the pressing process as well, and then look at the nutritional composition table, production date, and shelf life, and buy it according to the cooking method you need.
