A few simple tips on how to stay away from gutter oil

The Fuxi Incident in Shanghai has not disappeared yet, and the Gully Oil Incident in Taiwan has once again triggered a food safety storm. At present, 1247 enterprises have been affected. Many well-known brands such as Weiquan, 85C, Qimei, Meixin, Dale, Starbucks and 7-11 have been involved to varying degrees.

Now let's see how to identify the gutter oil in a sensory way to provide a safeguard for our healthy diet.

see

Look at transparency, pure vegetable oil is transparent, in the production process because of the mixing of alkali grease, wax, impurities and other substances, transparency will decline; Look at color, pure oil is colorless, in the production process because the pigments in oil dissolved in oil, oil will be colored; Look at sediments, its main component is impurities.

smell

Each oil has its own unique odor. You can drop one or two drops of oil on the palm of your hand, close your hands and rub them together, and carefully smell the smell when you get hot. Odorous oils indicate quality problems. Odorous oils are likely to be gutter oils; mineral oils are not available if they smell.

taste

Take a drop of oil with chopsticks and taste it carefully. Oil with sour taste is not a qualified product. Oil with tar and bitter taste has gone sour. Oil with peculiar taste may be gutter oil.

hear

Take one or two drops of oil from the bottom of the reservoir, apply them on flammable paper, ignite them and listen to their sounds. It is qualified product that burns normally and soundlessly; it is unqualified product that burns abnormally and produces "squeaky" sound with excessive water content; it is unqualified product that emits "cracking" explosion sound when burning, which indicates that the water content of oil is seriously exceeded the standard, and it may be adulterated product, and absolutely can not be purchased.

ask

Ask the merchant's purchasing channel, ask for the invoice or check the sample inspection report of the local food hygiene supervision department if necessary.

Seeing, smelling, tasting, listening and asking above are simple sensory identification, and in real life, they can not effectively distinguish the gutter oil products. When we buy oil, we try to choose regular packaged company brand products. Relatively speaking, regular company self-regulation will be more stringent and the quality will be more guaranteed.
