Anonymous users2024-01-24Once "gutter oil" enters the market, consumers must learn to distinguish with their senses. According to experience, edible vegetable oil can generally be identified by five aspects: looking, smelling, tasting, listening and asking.
Take a look. Looking at the transparency, the pure vegetable oil is transparent, and the transparency will decrease due to the mixing of alkali lipids, waxes, impurities and other substances in the production process; Look at the color, the pure oil is colorless, in the production process because the pigment in the oil is dissolved in the oil, the oil will be colored; Looking at the precipitate, its main component is impurities.
Second sniff. Each oil has its own unique smell. You can put a drop or two of oil on the palm of your hand, rub it with your hands together, and smell it carefully when you are hot. If there is a peculiar smell of oil, it means that there is a problem with the quality, and the smell is likely to be gutter oil; If there is a smell of mineral oil, you can't buy it.
Three tastes. Take a drop of oil with chopsticks and taste it carefully. Oil with a sour taste is an unqualified product, oil with a burnt bitter taste has become rancid, and oil with a peculiar smell may be "gutter oil".
Four listening: Take a drop or two of oil from the bottom of the oil layer, apply it to a flammable piece of paper, light it and listen to its sound. Qualified products are those that burn normally and silently; If the combustion is abnormal and makes a "squeak" sound, the moisture exceeds the standard, and it is an unqualified product; When burning, there is a "crackle" explosion, indicating that the moisture content of the oil is seriously exceeded, and it may be an adulterated product, so it should never be purchased.
Five questions: ask the merchant's purchase channel, and ask for the purchase invoice or check the sampling test report of the local food safety supervision department if necessary.

Anonymous users2024-01-23The landlord asked the profoundness.,I'll tell you that I don't have any.。。。 Gutter oil is not only not clean but also uses melted oil many times, just like the oil for frying fritters, it cannot be said that it is all gutter oil, and some are also rapeseed oil, but how many times can it be regarded as unhygienic clean? That has to be exposed to the public or know by yourself, who do you ask, how many people are food inspection departments?

Anonymous users2024-01-22Test it yourself. Pour the point into a bowl and put it in the refrigerator for 2 hours to freeze. There is a white layer of gutter oil.
Yesterday I bought a bucket of 5L, I thought it shouldn't be too bad, but I used this to cook, the color is obedient, and it has a bit of bitterness, I made a bear's paw tofu, and when I fried the tofu, I felt like it was boiled in water, and after the tofu was fried, the oil became like muddy water, and my own rapeseed oil was not like it at all, and the tofu tasted very bitter and greasy!! It's better to buy blended oil!
White stubble furniture brushing rapeseed oil should be on some of the paint accordingly, otherwise, just a kind of rapeseed oil, its brightness is not enough.
If it is a clean plastic bucket and it is sealed, the temperature of the bathroom is generally low and stable, and the light is relatively small, which is conducive to the storage of rapeseed oil! You can put it for a longer time, and if it has been opened, don't put it in the bathroom, because the humidity is relatively high, and it is easy for rapeseed oil to spoil!
In this case, it is necessary to rely on the detergent treatment, you can use the characteristics of oil oxidation when exposed to heat, first spray the oily detergent on the stubborn dirt that is difficult to remove, then spread a layer of plastic wrap, heat it with a hair dryer at a distance of about 10CM for about 2 minutes, and then wipe it with a rag. However, this method is not suitable for objects that will deform or change color when exposed to heat, so special care should be taken. You can also use a detergent to remove the oil from the surface first, and then use a "wipe clean" to remove the final dirt.
To get rid of the old oil smell first of all to find the source of the smell, generally the old house absorbs a lot of oil on the walls and floors for a long time, usually emitting this oil smell, in addition to the old range hood will also have this smell, so to remove the oil smell first to clean the wall, redo the ground, can be inlaid with tiles is the best inlaid tiles, so that it is not easy to absorb oil in the future, the range hood is now very cheap can be replaced with a new one, so that after processing, the kitchen basically does not have the old oil smell of the past.
