The appearance of edible oil mixed with gutter oil is no different from that of ordinary edible oil, and there is no obvious abnormality. Commonly used test methods cannot be identified. Some media speculated that gutter oil may contain aflatoxin, and the claim that aflatoxin poison is 300 times stronger than arsenic is mistakenly claimed to eat 3 million tons of arsenic per year. Therefore, some media have fabricated and exaggerated the description of gutter oil.

From the appearance, sensory color and sense of smell and common detection and identification methods, it is impossible to distinguish between incorporating gutter oil and ordinary oil.

It is reported that some finely processed gutter oils on the mainland Chinese market can already pass the national standard for edible oil testing. This does not mean that the quality of these oils has met the food safety requirements, but that they use some methods in processing for national standards. They still contain dangerous ingredients.

Although scientists have not yet found an ideal means of detecting and identifying gutter oil, consumers can learn to identify the true and inferior edible oil through five aspects: seeing, smelling, tasting, listening and asking.

When you look at the transparency, pure vegetable oil is transparent. During the production process, the transparency will decrease due to the mixture of alkaline fat, wax, impurities, etc.; when you look at the color, pure oil is colorless, and during the production process, the oil will be colored because the pigments in the oil are dissolved in the oil; when you look at the precipitates, its main component is impurities.

Secondly, smell the unique smell of different oils. You can drop one or two drops of oil on your palms, rub them with your hands together, and carefully smell the smell when it is hot. Oil with a odor indicates that there is a problem with the quality, and the smell may be gutter oil; if there is a smell of mineral oil, you cannot buy it.

Trial its taste three times. Oils with sour taste are unqualified products. Oils with burnt and bitter taste have already become rancid, and oils with peculiar smells may be gutter oil.

Four listening to the sound, take one or two drops of oil at the bottom of the oil layer, apply it on a flammable piece of paper, ignite and listen to its sound. A qualified product that burns normally and does not sound sounds; a "squeak" sound that exceeds the standard moisture, which is an unqualified product; a "crackling" explosion sound is made during combustion, indicating that the oil's moisture content is seriously exceeding the standard, and it may be an adulterated product, so it must not be purchased.

Five questions about the merchant’s purchase channels, and ask for a purchase invoice or check the edible oil test report if necessary.

The gutter oil found today is the gutter oil of No. 1 Middle School. If ordinary people are not able to find the problem here, only Jiang Feng’s sensitive feeling of a super expert who has reached the innate realm can find that there is something wrong with the smell.

In other words, if it weren't for being with Jiang Feng, Premier Wen would have to taste the taste of gutter oil himself.

"How could this happen?" After hearing this report, Premier Wen felt very angry when he thought that he almost ate gutter oil. "What did the quality supervision department do in a day? Such things should be their work responsibility, why have they never checked it? If I hadn't discovered this when I had dinner with President Xiao Jiang today, I would have been kept in the dark!"

When Premier Wen was angry, the problem became very serious. Soon, the head of the State Administration of Quality Supervision and the head of the food safety department rushed over. When he saw Premier Wen getting furious, he felt a little nervous.

When they heard Premier Wen ask about gutter oil, both sides were confused. It was obvious that they themselves didn’t know what gutter oil was. Later, they called experts from the State Administration of Quality Supervision and the experts from the National Grain and Oil Society, and everyone understood what this was.

Experts told Premier Wen that there is no unified standard for detecting gutter oil in China. In the current national mandatory standard "Edible Vegetable Oil Hygiene Standard" (2716-2005), the physical and chemical indicators for edible oil include acid value, peroxide value, leaching oil solvent residue, free phenol (cottonseed oil), total arsenic, lead, aflatoxin, benzopyrene, and pesticide residues, and different standards are tested for plant crude oil and plant edible oil respectively.

However, plant crude oil and plant edible oil are not gutter oil. The 9 basic edible oil testing indicators in the standard may pass the oil refined from gutter oil, and it is impossible to identify and test the name for gutter oil.

Officials from relevant departments who rushed over frankly said that if it weren't for Premier Wen asking about gutter oil this time, they had never even heard of the term gutter oil.

"You are a corpse-positioning meal!" Premier Wen said furiously, "Then I don't ask what you can't do, I'll ask, what can you do?! It's just that during the holidays, I go to the market for a while, and then I have been taking the goods as a sample for many years as a sampling sample. Or do I charge the inspection fees twice a year, which makes the public resentment? Apart from these, what else can you do?!"

Everyone looked at each other, and Xindaowen, why did Premier Wen even know about this? Who probably reported this in front of him? Otherwise, how could he know about this?

When everyone was thinking about this, they turned their eyes to Jiang Feng sitting on the side, thinking that it must be the boy who made a report. However, they quickly turned their eyes away because these guys were all deputy ministerial level.

The above big names, and all of them are from central ministries and commissions, are not unfamiliar with Jiang Feng. They dare not treat Jiang Feng as they make a report, so they still look down on them.

In fact, the quality inspection department also has its own difficulties on this issue. At present, the country has not issued a unified testing method and standard, which has brought insufficient judgment basis to the report of many ingredients that cannot be added. Therefore, they are not able to issue certain testing reports. Some merchants can also grasp this point after their products are found, claiming that there has never been a gutter oil indicator in the food safety inspection report. Regarding the name of gutter oil, the country has not issued official materials.

It is prohibited without checking, and there is no standard to follow, and there is no basis for the basis, which makes it impossible to effectively prohibit oil such as gutter oil.

According to the available data, "gutter oil" emerged in the 1990s. Illegal additives were basically products of the same era as "gutter oil", and even earlier than "gutter oil". More than ten or twenty years have passed, and today we are not clear about the impact of "gutter oil" on human health, so it should not be. Is this because "gutter oil" and illegal additives are not worthy of attention, or is it difficult to evaluate the impact on human health?

Taking "gutter oil" as an example, the media has reported a lot of impacts on human health, such as indigestion, diarrhea, gastric cancer, intestinal cancer and other diseases. It can be seen that the impact of "gutter oil" on human health is not difficult to evaluate. If you analyze harmful substances in "gutter oil" or let the hospital count relevant cases, you believe that the evaluation results will be soon. However, the information obtained by the public is "needed to be evaluated". As for when the evaluation results will be available, it is still a question mark.

"Gutter Oil" has appeared for many years, but there is no answer to the assessment of the impact of human health so far. The reason is not that it is difficult to evaluate, but that the relevant public services are too lagging behind "gutter oil" for many years. It is obvious that if health services cannot keep up with the pace of "gutter oil", they cannot accurately judge the harm of "gutter oil", and then affect the efforts to control "gutter oil". From this perspective, the health department may have negligence.

"No matter what, what are you doing over the years?" Premier Wen naturally refused to listen to their ruthlessness. In fact, as Premier Wen said, they were not interested in collecting money, but they did not have any enthusiasm for actively conducting business, which led to today's situation.

Finally, Premier Wen asked all departments to conduct self-inspection and correction to see how many additives that endanger food safety cannot be checked or have no processing standards within their respective jurisdictions. He said that today, as the commodity economy is developing faster and faster, relying on the initiative and integrity of merchants is not enough, and the government department must take on its own responsibilities tangibly.

In addition, the food safety department is ordered to conduct random inspections of relevant products in major supermarkets across the country to determine whether there is still gutter oil.

After sending these people, Premier Wen said to Jiang Feng with some headaches: "Look, this is the case. From top to bottom, you don't realize where your responsibility is. When fighting for power and profit, everyone rushed up to break the head. When it was time to discuss responsibility, they would shrink their heads like turtles. If you sit in my position, you would have to be old for at least twenty years!"

Jiang Feng smiled slightly when he heard this, "I believe this, so I will never enter the officialdom. I will do my business with my conscience and be free and free. I will also contribute to this country and nation, and I will do a great job. What's wrong with it?"

Premier Wen shook his head after hearing Jiang Feng's words and said, "Your idea seems to make sense at first glance, but it is not right. It is precisely because of this system that we have to work harder to transform it. Otherwise, what else do we need to do?"

"I don't deny this. Actually, I still admire your labor efforts." Jiang Feng said righteously.

"I can't see anything that I admire. I guess you are laughing at us in your heart now that we are laughing at us for being pedantic and unrealized!" Premier Wen would not be moved by Jiang Feng's words, and shook his head with a smile.

The two of them discussed for a long time, and they were all related to the national economy and people's livelihood, and Premier Wen was unlikely to know. After all, in such a general environment, people with the status of Premier Wen could not be exposed to it. Just like he went down to inspect, it was also carried out according to a fixed route under the arrangement of local governments. Things like private visits were very resentful to everyone.

After having supper with Premier Wen, Jiang Feng said goodbye and left. (To be continued.)
