Recently, the news that tanker trucks transport edible oil affects food safety has attracted widespread attention.
As early as 19 years ago, in 2005, the Nanguo Morning Post reported that "it is difficult to prevent cross-contamination after tanker cleaning and pulling food after pulling dangerous chemicals".
According to the report, gasoline was pulled to pull molasses, diesel was pulled to alcohol, caustic soda was pulled and hydrogen peroxide was pulled...... It is such a tank truck, but it has become a frequent customer of some roadside car washes in Nanning......
Edible oil is polluted by industrial gasoline, kerosene, diesel and other mineral oils! As a result, some netizens recently suggested eating self-pressed oil. However, today's hot search news also said that self-pressed oil aflatoxin is easy to exceed the standard.
Aflatoxins have strong acute toxicity as well as significant chronic toxicity. As early as 1993, it was defined by the World Health Organization as a Group 1 naturally occurring carcinogen and is one of the strongest known carcinogens.
Moreover, aflatoxin is very close to our daily life, and it can be produced from rotten food and damp boards.
What to do? It was also found that the website of the State Intellectual Property Administration can see that a number of applicants have applied for patents related to the removal and degradation of edible oil aflatoxin.
The picture is from the CNIPA website
Including "a method for removing aflatoxin in edible oil", "a method for rapid removal of aflatoxins in edible oil", "a method for removing aflatoxins in peanut oil", "automatic control circulating peanut oil aflatoxin degradation machine", "peanut oil aflatoxin degradation tank and degradation machine" and other patents, applicants include universities, scientific research institutes, food companies, mechanical and electrical companies, equipment companies, etc., some of which have been authorized.
In the above patents, the methods for removing aflatoxin include the use of chemical adsorption and irradiation through ultraviolet lamps. Since so many patents have been granted, have they been used in actual production?
In fact, as early as 2012, Luhua advertised that it had overcome the world's problems and developed aflatoxin removal technology, which removed aflatoxins through low-temperature physics without using chemicals, and this process did not change the quality characteristics of peanut oil such as nutrition and flavor.
Inquire about the relevant patents, this is a utility model patent applied for in 2006, named "a device for removing aflatoxins", patent abstract: the utility model discloses a device for removing aflatoxins, is provided with an ultraviolet pyrolysis device on the pipeline, the device is provided with an ultraviolet generator in the center of the shell, a gap is formed between the shell and the ultraviolet generator, a plurality of ultraviolet cracking devices are connected in series in the pipeline, and the ultraviolet generator is formed by a plurality of ultraviolet generators in parallel, Be provided with cooling device on the pipeline after each pyrolysis device, the inner wall of the shell is a reflective layer, and the utility model has the characteristics of adopting physical method, utilizing ultraviolet irradiation to make aflatoxin all decompose and remove, the operation process is not subject to any external pollution, does not change the nutritional composition and inherent flavor of the processed food, the degree of mechanization is high, the processing capacity is high, and is suitable for the characteristics of continuous large-scale production.
The abstract shows that Luhua is also a place where aflatoxin is carried out by ultraviolet irradiation. The term of protection of a utility model patent is 10 years, which means that the patent expired in 2016. This also means that everyone can adopt this approach.
After discussing for so long, the question now is that the safety of edible oil is not that the technology is not up to par, but how to take measures to ensure safety? Can edible oil companies also carry out a blue sky action?
