The owner of the wholesale store saw Duan Zetao's surprised expression, and introduced it a little proudly: "You can definitely rest assured that you buy my oil, that is, the health and epidemic prevention department will definitely not find out the problem when you go to your restaurant ...".
Speaking of the wholesale store owner walked to the corner, picked up a bottle of sealing small bottled brand to eat oil, and opened a bucket of bulk band edible oil, poured some of the transparent plastic cups, and the bottle -sealed brand edible oil placed
Together, some are morally authentic: "You see the color of this oil, it is very transparent. You can't tell what the difference between these two oils is with the naked eye ...".
Then he picked up the transparent plastic cup and handed Duan Zetao. "You can also smell it and ensure that there is no odor! Come here to buy oil are big customers, there are big hotels, and school canteens
, The amount of goods is very large, there are dozens of barrels at a time ... ", the wholesale store owner has eloquently sold his oil.
Duan Zetao was even more surprised. The cup of oil in front of them was too different from the groove oil in their impression, which also shows that these black -hearted merchants of these ditch oil are also "advancing with the times", and this kind of qualified edible oil is completely completely consumption oil.
The "refined ditch oil" that cannot be seen is even more concealed. It can flow into the big hotel and school cafeteria, and its harm is even greater.
In the end, Duan Zetao bought ten barrels of "refined ground oil" back. This time, when Duan Zetao came, they also brought some simple detection instruments and a staff member who knew the test. After returning, they immediately extracted these ten barrels of oil extraction.
Ten samples were tested with detection instruments.
As a result, the test results surprised everyone, because the test results of these ten sample oil actually met the requirements of the general indicators of edible vegetable oil and edible animal oil!
"How can this?! Isn't we buying a trench oil this time?!", Duan Zetao seriously said very seriously to the staff responsible for testing.
The staff responsible for testing also said at a loss: "Ditch oil testing has always been a problem for us. Just now I follow the conventional edible oil testing standards for polygon aromatic hydrocarbons, cholesterol, conductivity, specific gene composition of these ten sample oil, composition
And several harmful substance indicators such as acid prices were tested, and no abnormalities were found ... "
"But this does not rule out that these oils are not ditch oil. They also need to detect several harmful substance indicators such as patelin B1, trans fatty acid and benzene.
There is no way to detect these indicators in the testing equipment this time. If you must detect it, you can only return it to the detection center of the State Administration. Only there will be a special testing equipment that can detect these harmful substance indicators ... ".
Duan Zetao frowned and asked: "Since patelomycin B1, harmful substances such as trans fatty acids and phenylpheniane are harmful to human health. Why do our edible oil detection standards not incorporate these indicators into conventional testing indicators?
?! ... ".
The staff responsible for testing hesitated: "Now the production of edible vegetable oil in my country generally uses two methods: physical presumption method and chemical immersion method. The physical presumption method is low because of the low output rate, so many formal edible oil production is now produced by many formal edible oil production. Most of the manufacturers will choose chemical immersion method, but chemical dipping oil technology will use chemical reagents throughout the process. Vegetarian B1, trans fatty acids and benzene pheasant and other harmful substances, and these kinds of substances are also the main harmful substances in ditch oil, so it is very difficult to distinguish between ditch oil and qualified edible oil ... " Then, then
Duan Zetao nodded, and his face was dignified: "It seems that our edible oil detection standards still have a big omissions. After we go back, we must organize the technical department to keep in terms of research.
Oil testing methods! ... ".
At this time, Mantan Mountain and Hu Tielong walked in from the outside. When he went more like water, he exuded a sour smell. Everyone laughed at the sight. Zhu Wanjun was even more.
Holding his nose: "Horse, Brother Tielong, go and take a shower, otherwise we will be smoked to death! ...".
Duan Zetao also smiled: "Nanshan, Iron Dragon, you have worked hard, go to take a bath first, change your clothes, and then discuss it to see what the gains you have.
".
Mantan Mountain and Hu Tielong took a bath this time for nearly half an hour. After changing their clothes, they came out, and they still had a touch of strange smell. It can be seen that they live and work under what bad conditions they these days, so they came out, and they came out, and they came out.
Everyone looked at them with admiration eyes.
Duan Zetao filmed Ma Nanshan's shoulders and smiled: "Comrade Nanshan, so good! After returning to the game, I would call everyone to learn about you and Tielong.
Come, talk, what gains do you have?! ... ".
Ma Nangshan told their experience these days, "They may have learned that we have come down to investigate and are going to stop production for a while, so I and I Tielong and I stay there again. It seems that now it seems
The big boss behind this scene not only has huge power, strict organization, high vigilance, but also vast magical powers. The news is very cautious, which is very cunning! It seems not easy to catch this big fish!
The only important clue I got here is the license plate number. I hope that from this, I can find the specific information of the big boss behind that big behind -the -scenes! ... ".
Duan Zetao laughed: "No matter how cunning the opponent is, the fox tail will always be exposed! Nanshan, you have already caught the fox tail now, I believe it won't be long, this fox will completely surface, and nothing will be used.
It's a form! ".
Mantan Mountain nodded heavily. At this time, he also noticed the ten barrels of oil in the room in the room, and asked strangely: "Where did these oils come from? ...".
Duan Zetao also said that their experience in the wholesale market also said that Mantan Mountain learned that these 'refined ditch oils' are actually bought from the wholesale market, and the QS certification logo is shocked.
Look at the samples of the ten 'refined groove oil', and suddenly I slapped my head: "I have a way to distinguish whether this is a trench oil! ...".
