Facing the "chaos in tanker transportation", technology protects "food safety"

Recently, some media investigated the chaos of tanker transportation and found that some domestic general cargo tankers transported different liquids. They not only transported edible liquids such as syrup and soybean oil, but also chemical liquids such as coal-to-liquids. In order to save costs, many tankers did not clean the tanks during the transportation process. Some edible oil manufacturers did not strictly control and did not check whether the tanks were clean according to regulations, causing the edible oil to be contaminated by residual chemical liquids. This matter subsequently attracted widespread attention.

What harm does mixing tank trucks do to the human body?

According to relevant professionals, coal-to-liquid oil is a chemical product that contains chemical raw materials such as heavy metals and benzene.After the oil tank is filled with chemical raw materials, there will inevitably be residues。

Long-term consumption of cooking oils containing these chemical residues may cause human poisoning, resulting in symptoms such as nausea, vomiting, diarrhea, and even irreversible damage to organs such as the liver and kidneys.

Food testing protects food safety

Food is the first necessity of the people, and food safety is the top priority.Ensuring that food meets safety standards at every stage from production to the table is an important basis for protecting public health, and food safety testing must not be slackened.

It is necessary to adopt scientific, efficient and accurate testing methods and a perfect testing system to conduct comprehensive and detailed monitoring and evaluation of harmful substances, additive residues, microbial contamination, etc. in food to ensure the safety of what you eat.

How to detect different oil products?

The use of Raman or near-infrared spectroscopy technology can effectively distinguish between gas and oil.Raman spectroscopy is a non-destructive molecular spectroscopy that can perform qualitative and quantitative analysis of substances and can provide good monitoring of gas and oil mixtures.It has the characteristics of fast analysis speed and no need to use any chemical reagents.

When a tanker truck enters the factory, we can test its residual oil to identify whether it was previously transporting edible oil and conduct efficient food safety testing.

 ▲Raman spectrum of edible oil

▲Raman spectrum of white oil

▲Raman spectrum of glycerol

As shown in the figure above, the characteristic peaks of the Raman spectrum of gasoline are 731cm-1, 995cm-1, etc.;

The Raman characteristic peaks of edible oil are 1298cm-1, 1439cm-1, 1656cm-1, etc.;

The Raman characteristic peaks of white oil are 1063cm-1, 1303cm-1, etc.;

The characteristic Raman peaks of glycerol are 1055cm-1, 1378cm-1, etc.

Coal-to-oil and mineral oil can be identified through different Raman characteristic peaks.

Near-infrared spectroscopy is also a type of molecular spectroscopy, which can also conduct qualitative and quantitative analysis of substances. By analyzing the functional groups of different molecules in edible oil and coal-to-oil, it can effectively distinguish between edible oil and coal-to-oil.
