Gutters are underground sewers. So, what are the harmful effects of gutter oil that people often say? Let’s start with what gutter oil is and learn more about “gutter oil”!

1. What is waste oil?

In layman terms, gutter oil can be divided into the following categories: First, gutter oil in a narrow sense, which refers to the greasy floating objects in the sewer or leftovers from hotels and restaurants (commonly known as swill). The oil is simply processed and refined; the second is the oil produced after processing and refining low-quality pork, pig viscera, and pig skin; the third is oil used for fried foods that has been used more than the specified requirements and then is reused or added to it. Oil that is reused after adding some new oil.

2. Advantages and Disadvantages of Gutter Oil:

Advantages of Gutter Oil: Gutter Oil produces biodiesel. According to experts, after the waste oil is added to the reaction tank, its alcoholysis and esterification can be carried out at the same time through a slightly acidic catalyst technology, and the reaction speed is also significantly accelerated. In addition, a metal salt treatment agent solves the key problem of using waste animal and vegetable oils to produce diesel with high residual acid value. These two key technologies have reduced the production cost of biodiesel, allowing biodiesel to move from the laboratory into the production workshop. The biggest feature of this fuel is that it has good environmental protection. The exhaust gas emitted by diesel vehicles does not contain sulfur dioxide, and hydrocarbons and carbon monoxide are also greatly reduced.

Disadvantages of gutter oil: Garbage oil is non-edible oil with extremely poor quality, extremely unhygienic, and seriously exceeds the peroxide value, acid value, and water content. It contains toxins, and if it flows into rivers, it will cause nutrient content in the water. Once eaten, it will destroy white blood cells and the mucous membrane of the digestive tract, causing food poisoning and even cancer. Frying oil, one of the "vegetable oils", is used repeatedly at high temperatures for a long time. When it comes into contact with oxygen in the air, complex reactions such as hydrolysis, oxidation, and polymerization occur, resulting in an increase in oil viscosity, a deepened color, an increase in peroxide value, and It produces some volatile compounds and substances with pungent odors such as aldehydes, ketones, and lactones, which are carcinogenic. The main hazard in "swill oil" is the toxicity of aflatoxin. According to medical research, it is 68 times more toxic than arsenic.

3. What are the sources of gutter oil and what are the hazards of gutter oil?

(1) Sewers are called trenches. Gutter oil is the residue of household oil that accumulates in sewers over many years. Nowadays, many unscrupulous traders go to restaurants and other places where cooking oil is used a lot, take out the oil that others wash into the sewers from their gutters, and then directly reuse it... Especially in Shenzhen, China, the most prominent, roadside food stalls, breakfast vendors The use of sewage oil is obvious. The most shocking thing is that a large chain restaurant in Shenzhen, "xx Frog", also discovered the use of sewage oil. However, the Shenzhen Health Bureau has now strictly controlled most regular businesses, but many roadside snacks The problem remains serious.

(2) There is no obvious difference in color and taste between mixed gutter oil and ordinary bulk cooking oil.

(3) According to experimental measurements, the rancidity index of "gutter oil" far exceeds the national regulations. Long-term intake will cause people to lose weight and have developmental disorders, be prone to diarrhea and enteritis, and have liver and liver diseases. Diseases such as heart and kidney enlargement and fatty liver. In addition, the aflatoxin toxicity produced by contaminated gutter oil not only easily causes liver cancer, but can also cause tumors in other parts of the body, such as gastric adenocarcinoma, kidney cancer, rectal cancer, breast cancer, ovary, small intestine and other parts of the body.

Anorectal experts explained that "gutter oil" is indeed the enemy of people's health, especially its gastrointestinal health, which has immeasurable destructive power.

1. "Gutter oil" can cause indigestion

In the process of refining "gutter oil", animal and vegetable oils undergo a series of chemical processes such as rancidity, oxidation and decomposition after being contaminated. Changes, producing substances that are highly toxic to the human body; arsenic is one of them. Once people use "gutter oil" with a huge amount of arsenic, it will cause symptoms such as indigestion, headache, dizziness, insomnia, fatigue, and liver discomfort. .

2. "Gutter oil" can cause diarrhea

The production process of "gutter oil" is doomed to be unhygienic, and it contains a large number of bacteria, fungi and other harmful microorganisms once it reaches people. In the intestinal tract, mild cases can cause diarrhea in people, while severe cases can cause a series of gastrointestinal diseases such as nausea and vomiting.

3. "Gutter oil" can cause severe abdominal pain

"Gutter oil" is mixed with a large amount of sewage, garbage and detergents. It is refined in the open air in underground workshops and cannot remove bacteria at all. and harmful chemical ingredients. It is an indisputable fact that all "gutter oil" will contain lead that seriously exceeds the standard. Eating food made from "gutter oil" that contains excessive lead will cause symptoms such as severe abdominal cramps, anemia, and toxic liver disease. .

4. "Gutter oil" can cause gastric cancer and intestinal cancer

The disgusting refining process is the reason for the growth of gutter oil toxins. "Gutter oil" is a refined oil produced by processing and refining gutter oil (swill, leftovers, etc.) collected from hotels and restaurants to remove the odor and flowing to the edible oil market. Gourmet oil contains aflatoxin and benzopyrene. These two toxins are carcinogens and can cause gastric cancer, intestinal cancer, kidney cancer, and cancer of the breast, ovary, small intestine and other parts of the body.

Anorectal experts remind consumers that once symptoms such as abdominal pain, nausea, and vomiting occur after eating in restaurants, food stalls, or vendors, they must go to the hospital for treatment as soon as possible. To avoid causing more harm to your body.

The main hazard in "swill oil" - aflatoxin is 68 times more toxic than arsenic.

Raise health awareness and avoid eating gutter oil.
