How to choose a good peanut oil when you buy oil in the store?

Good oil does not smoke when the temperature is low.

First, look at the quality standards of peanut oil. The new peanut oil standard is divided into two series: physical pressing and leaching (solvent extraction). Pressed peanut oil is divided into crushing primary and crushing secondary.

Leaching peanut oil is divided into leaching grade 1 to 4. As for the strong fragrance, special fragrance and other titles, it is just that the process of pressing peanut kernels is different.

Second, look at the production date. Peanut oil is a food, and freshness is the best. The flavor substances of peanut oil exist in the oil by adsorption in the process of oil making, so this flavor substances are easy to volatilize or decompose.

Peanut oil has an automatic oxidation, decomposition process even during the shelf life. If the peanut oil is left for a long time, the aroma will gradually fade until it disappears, and the acid value will also rise, the peroxide will increase, the taste will deteriorate, and the nutrients will be destroyed. Generally speaking, peanut oil produced recently is more intrinsic than peanut oil produced earlier.

3. Look at the senses. The peanut oil squeezed from fresh peanuts is natural, golden and bright, and smells like peanut oil. If the peanut oil squeezed out of the peanut kernels that are moldy or past the summer is dark in color, dull, bitter in smell, astringent in taste, light in the mouth, and has a feeling of being stuck in the throat.

Fourth, the actual test. Good peanut oil appears at a high temperature of oil smoke. And as the temperature rises, the color of peanut oil basically does not change, and the taste is still smooth and deep after high temperature.

If the peanut oil is already full of wolf smoke at low temperatures, and the fragrance is quickly dissipated, it is definitely not a good peanut oil.

Fifth, look reasonable**. Many consumers think that the high price is ***, but in fact, this is a misunderstanding. Even though the production process of each manufacturer is slightly different, the pure manufacturing cost of peanut oil of the same level and specification is almost the same.

Some manufacturers add heavy advertising costs and sales costs to the products they recommend, or take advantage of consumers' "** is high-quality" psychology to set the price of the product extremely high.

High price does not mean good quality.

Judging from the sampling of the peanut oil market announced by the national quality inspection department, the quality indicators of the same level of peanut oil of various manufacturers are almost the same, and the unqualified factors mainly appear on the logo. After the implementation of the new peanut oil standard, manufacturers are required to label the oil making process, product grade and other related content, which actually plays a role in educating consumers, and will promote the public peanut oil consumption to abandon the concept of supremacy and rationally turn to quality-oriented.

Look up online what brand is the best you need.

Sniff it with your nose and you'll know.

The earliest production of peanut oil has Luhua, orchid, Arowana, Fulinmen, etc., which are deeply loved by the general public. It should be considered a relatively good sales volume.

Peanut oil is a relatively easy edible oil to digest. Peanut oil contains more than 80% unsaturated fatty acids. It also contains saturated fatty acids such as palmitic acid, stearic acid and eicosanic acid.

The fatty acid composition of peanut oil is relatively good, which is easy for the human body to digest and absorb. In addition, peanut oil also contains sterols, wheat germol, phospholipids, vitamin E, choline and other substances that are beneficial to the human body. Regular consumption of peanut oil can prevent wrinkles and aging, protect blood vessel walls, prevent thrombosis, and help prevent arteriosclerosis and coronary heart disease.

The choline in peanut oil can also improve the memory of the human brain and delay the decline of brain function. It is one of the rare edible oils.

The peanut oil of Arowana is relatively good, because of the occurrence of Arowana, the peanut oil of Arowana is relatively good, because the peanut oil of Arowana, its taste and color are non-Arowana peanut oil is relatively good, because of the peanut oil of Arowana, its taste and color are very lubricated. The taste of it is also very good, because the peanut oil of Arowana is very lubricated, and the taste and color of it are also very good.

There are many brands and qualities of peanut oil that are easy to use.

Now there are many varieties of peanut oil quality, such as Luhua peanut oil, such as orchid peanut oil, such as Arowana, peanut oil.

The key is that you have to see the blending concentration of peanut oil and the proportion of naughty oil, some peanut oil, he has other oil products.

Some peanut oil is pure peanut oil, while some peanut oil has other oils and fats added to it, is it not pure to blend peanut oil?

Therefore, good peanut oil is pure peanut oil, not prepared peanut oil.

It's good to squeeze it yourself.

In fact, the quality of the edible oil bought in the supermarket is guaranteed, and most of the oil sold in the supermarket is from large manufacturers, such as Luhua, Arowana and other brands.

However, most of the edible oil in the supermarket does not have the aroma of self-squeezed oil, this is because large factories generally use the method of organic solvent extraction to extract oil, which has a high oil yield, but the fragrance is relatively light, which makes many people who are used to eating self-pressed oil not accustomed to the main reason for not being accustomed to refined oil.

Many people like to press oil by themselves, mainly because the raw materials are their own, plus they can see it when processing, and they feel very safe. But self-pressed oil also has a fatal drawback, which is that it may contain Aspergillus flavus.

In the rural areas, there are basically small oil mills, these small oil mills have poor machines, and there is no equipment to remove Aspergillus flavus, in the list of suspected carcinogens announced last year, rural self-pressed peanut oil occupies the first place, which is mainly related to the rural oil extraction equipment does not remove Aspergillus flavus equipment.

In comparison, it is better to sell regular oil in supermarkets, but it should be noted that to buy oil, you must go to a regular supermarket to buy big brands of oil, and you must not try to buy cheap oil sold by small stalls, it is likely to be the oil squeezed by the black-hearted boss with scraps.

In general, the regular oil bought in the supermarket is still a little better, of course, it does not refer to the kind of small supermarket, everyone still has to go to the regular big supermarket to buy the kind with the brand, but don't try to buy the kind of small stall vendor cheaply, because if you are not careful, you will buy the scrap oil of the black-hearted boss!

Of course, it's the peanut oil that I squeezed myself.

The peanut oil sold in the supermarket is not pure, and other low-quality oils are added.

Therefore, peanut oil in supermarkets is sometimes cheaper, because other low-cost oils are added.

I recommend going to a big supermarket to buy a big brand of peanut oil, because peanuts are particularly difficult to store, if the storage method is not large, Aspergillus flavus will be produced, and the naked eye can not distinguish, so the requirements of large factories are more stringent, and the quality is more ***, it is not recommended to buy homemade peanut oil in the countryside, because the pressing process is limited, and it cannot be taken into account everywhere.

Of course, it is better for rural people to squeeze their own peanut oil, because this self-squeezed oil does not add any preservatives, nor does it add other oils, and the taste is more pure.

The peanut oil sold in the supermarket is good. The peanut oil sold in supermarkets is generally made through advanced technology, and the safety level is higher, so the peanut oil sold in supermarkets is better.

Careful citizens may find that when peanut oil is placed in a lower temperature place in winter, the peanut oil will coagulate to varying degrees, some will be half solidified, some only have a little coagulation at the bottom, and some will mostly or even completely coagulate. In this regard, experts said that it is normal for peanut oil to coagulate when the temperature is lower than that of Qi Chunji, but only half of the coagulation is pure peanut oil.

Three notes on choosing peanut oil:

The first is to identify the brand and be wary of the "three nos" from unknown sources. "Farmers produce their own peanuts, hand-squeeze, physical pressing, and primitive soil pressing"The author learned from the market and shopping ** that some merchants sell farmhouse peanut oil** much more preferential than brand merchants, but they do not standardize the QS quality and safety certification, trademark label pants or product labels, which belong to the "three no products".

Zeguo Industry and Commerce reminds consumers that most of the "three no-products" lack the necessary sterilization, disinfection, inspection and quarantine conditions, and there are serious food safety hazards and edible risks, such as poisoning and death. Consumers should try their best to go to the regular market or supermarket to buy "Luhua", "Arowana", "Fulinmen", "Duoli" and other well-known brands of peanut oil, refuse to buy "three no" products and actively report to the industry and commerce, food and drug regulatory authorities.

The second is to choose sellers with good reputation, and be cautious about buying bulk oil. At present, the quality of barreled oil sold on the market is generally better than that of bulk oil, because the sealing of bulk peanut oil is not good, it is easy to deteriorate, and it is difficult to detect adulteration. It is recommended that consumers try to choose large supermarket chains or shopping malls with large scale, good reputation and mature operation system to buy barreled oil with strict packaging, complete labeling, and close to the purchase date of production.

Open the package as soon as possible after purchase, and the storage date should not exceed one year, and pay attention to keep the shopping receipts or receipts to ensure that there is a basis for consumer disputes and protect their own rights and interests.

The third is to master the identification method of high-quality peanut oil. Do "one look, two smells, three tastes, four listens, five fried and six refrigerated": look at the color and transparency, the color of high-quality peanut oil is light yellow or brownish yellow, good transparency, no impurities, sediment and suspended solids;Second, the high-quality oil has a rich and long-lasting peanut fragrance and does not have any pungent odor;Three tastes, rancid, bitter, mildew, burnt, grassy peanut oil should be avoided;Four listen to the sound, the high-quality oil is silent after burning on the paper;Five stir-fried, the color of high-quality peanut oil has no obvious change after being put into the pot, there is no overflow, foaming or fume, and the color becomes dark and black for inferior peanut oil; 6. Put it in the refrigerator and refrigerate, if the peanut oil is more than 15 or less than 5 does not solidify, it should attract the attention of consumers.

Peanut oil can improve the taste of food and stimulate people's appetite, so it is deeply loved by people. There are many types of peanut oil in the market, and different peanut oils have different nutritional benefits. So how to choose high-quality peanut oil? Let's take a closer look!

Look at its "primary color".

High-quality peanut oil has a yellowish-red appearance in the color and luster of the oil. This feature is mainly due to the fact that high-quality peanut oil is made by physical pressing process, and the production process completely relies on physical pressure to directly separate the oil from the oil, without using chemical leaching and high-temperature refining, without going through the six decolorization processes such as "dewaxing" and "decolorization", so as to retain the natural original color of raw peanuts.

Smell its "original fragrance".

After opening the cap of the oil bottle, you can smell the mellow and rich natural fragrance of peanuts. This feature also depends on the physical pressing process, which produces peanut oil through a pure physical pressing process, which retains the natural aroma of the raw material in the oil, while the chemical leaching process destroys the active nutrients and aroma of the oil.

Identify its "original species".

Check the raw material non-GMO label on the outer packaging of the peanut oil product. High-quality peanut oil has a great relationship with the quality of the raw materials themselves, and the quality of the raw materials directly depends on the original seeds, natural high-quality, non-GMO peanut seeds can ensure the high quality of peanut oil raw materials, thereby ensuring the safety of peanut oil products.

Know its "original pressing".

Check the production process identification on the outer packaging of the peanut oil product. High-quality and pure peanut oil is produced by pure physical pressing process, taking the current domestic advanced Luhua 5S pure physical pressing process as an example, Luhua 5S pure physical pressing process directly squeezes the oil out of the oil through the original pressing method, the whole production process does not use any chemical agents, does not go through high-temperature refining, does not add any antioxidants, and uses high-tech technology to achieve a breakthrough in peanut oil Aspergillus flavus is not detected, reaching the world's leading level, and the safety of the human body is more guaranteed. Luhua 5S pure physical pressing process not only ensures the safety and health of the oil, but also can completely retain the natural nutrients and active substances of the raw peanuts in the oil.

Taste its "original taste".

High-quality peanut oil often only squeezes the first peanut juice, and the original peanut juice is squeezed through the original seed, and finally the natural original fragrance of peanut oil is realized, which ensures the pure taste of peanut oil and tastes natural and healthy.

Verify its "originality".

The most noteworthy. The trick to identify pure peanut oil is to test the physical properties of peanut oil by refrigerating it. Pure and high-quality Hua Hongchai raw oil will show coagulated or semi-coagulated characteristics below 12.

The method is to adjust the temperature of the refrigerator to below 12, and then put the peanut oil into the refrigerator for about 10 minutes, the pure peanut oil will coagulate or semi-coagulate, which is the physical characteristics of pure peanut oil, and it is also the simplest and most effective way to identify whether the peanut oil is pure.

In general, high-quality and pure peanut oil should have the characteristics of original seed, original pressing, original color, original fragrance, etc., and is the high-quality and healthy edible oil that can best interpret the "taste of China".
