Caramel Colouring Causes Cancer (E150d)?

Postby Mark C » 18 Feb 2011, 11:41

This is interesting, although I assume it is E150d they are talking about. Will need to check the difference with E150a again.

A consumer advocacy group says chemicals that give cola its distinctive caramel color may cause cancer.

CBS News Medical Correspondent Dr. Jennifer Ashton explained on "The Early Show" that the Center for Science in Public Interest (CSPI) is concerned about a chemical that is liberated during the production process of making colas.

"They say (the chemical) has been found in government studies to cause cancer in animals. The State of California is so concerned about this that they have listed one of these ingredients on their list of substances known to cause cancer, and they want to limit the amount to no more than 16 micrograms a day," she said. "To put that into context for you, 20 ounces of cola can contain 12 times that amount."

The artificial brown coloring, according to the CSPI, is made by reacting sugars with ammonia and sulfites under high pressure and temperatures, and those reactions "result in the formation of 2-methylimidazole and 4 methylimidazole, which in government-conducted studies caused lung, liver, or thyroid cancer or leukemia in laboratory mice or rats."

E 150a is made using a different chemical reaction and it is said to be harmless.

BTW, E 150d is used in Coke and the quantities in a glass should be much larger than the E 150a in a dram of whisky.

I'm aware of that - double checked the different types. What I'm thinking, though, is that this article (and many others like it) will only mention 'caramel colouring' and probably not venture into the different types.

I think that is a really good point and one that can only help the campaign. If we say to the industry that your caramel could be confused with other harmful ones then they are going to want to do something about it. Hopefuly that will mean not using it and proudly displaying the apropriate logo to say so

Unfortunatly you are probably supporting the other side of the story which is it is better to not put it on the bottle so as to not confuse the consumer. You have to look at it from the industries point of view. Unless you are going to get the laws changed then you need to make it benificial to the industry.

I don't think it's good practice to suggest harmfulness if it hasn't been proven yet. And E 150d is in the same carcinogen leauge as acrylamide in chips or nitrosamins and polycyclic aromatic hydrocarbons in a grilled piece of meat. So eating a burger with chips and a coke will cause triple cancer.

I suspect the carcinogen qualities of alcohol to be stronger as any kind of caramel anyway.

'Proven' and 'accepted' are quite different things.

Then that means it's quite acceptable to add it to our alcohol then. We can increase the risk by adding a pointless additive.

A common quote -
Caramel coloring is burnt sugar. Ask any biologist about burnt sugar, and he will tell you that it is a carcinogen. Additionally, scientists have used caramel coloring in lab experiments on mice to interfere with leukocyte action (white cells). In other words, caramel coloring is immunosuppressive. The FDA knows this and insures that anything containing caramel coloring must note this on the label. Just luckily, this immunosuppressive property of caramel coloring drops away when you quit ingesting it.


From a UK site -
"In 1880, Charles Sethness, a 25 year old self-educated immigrant, started a flavor and syrup business in Chicago. Within a few years, he was heating sugar in iron kettles to produce caramel color for whiskey. Today, his grandsons and great grandsons run the Sethness Products Company, the world’s leading supplier of caramel color. Although the single largest use of caramel color is soft drinks, it is also used in an incredible number of other foods. Today, caramel color is manufactured by heating corn syrup, usually under pressure, in large stainless steel reactors."
I also learned that there are four classes of caramel color based on chemical additives:
· Class I Caramel Color (no additives low sulfites)

· Class II Caramel Color (sulfite additives very high sulfites)

· Class III Caramel Color (ammonia additives low sulfites)

· Class IV Caramel Color (sulfite and ammonia very high sulfites)
It seems that some caramel colorings are worse than others, depending on their chemical additives. Manufacturers are required to list caramel coloring when they use it, but they are not required to list the class.


Acrylamides may be more comparable to E150a than E150d ( or not ). Besides it's all about reducing risk.
Laboratory tests highlighted acrylamides as a possible danger five years ago, but the University of Maastricht study, published in the journal Cancer Epidemiology, Biomarkers and Prevention, is the first to find a link between acrylamides in the diet and cancer risk.
Food which has been coloured or burned by cooking is far more likely to contain acrylamides.
Food experts say it is virtually impossible to eliminate them from our diets altogether.
The Dutch study followed the 120,000 volunteers - 62,000 of whom were women - for 11 years after their initial questionnaire, during which time 327 of them developed endometrial (womb) cancer, and 300 developed ovarian cancer.
Analysis of these findings suggested that those who ate 40 micrograms of acrylamide a day - equivalent to half a pack of biscuits, a portion of chips or a single packet of crisps - were twice as likely to fall prey to these cancers compared with those who ate much less acrylamide.
Despite the size of the study, the researchers said that the results needed to be confirmed by other research.

An EU spokesman said: "General advice, resulting from this project, is to avoid overcooking when baking, frying or toasting carbohydrate-rich foods.

I was referring to your suspicion of E150a being a cancerogen. I do not see that this is accepted knowledge.

Wikipedia wrote:Internationally, JECFA has set the Acceptable Daily Intake (ADI) of Class I caramel color as "not specified"; that of Class II as 0-160 mg/kg body weight; that of Class III as 0-200 mg/kg body weight; and that of Class IV as 0-200 mg/kg body weight.

The United States Food and Drug Administration classifies and regulates caramel color in 21 CFR 73.85 as a color additive exempt from certification. Unless a food has a standard of identity, caramel color may be safely used in foods generally at levels consistent with good manufacturing practice.

The International Programme on Chemical Safety (IPCS) has concluded that commercially-produced caramel color has the same toxicological properties as caramel produced by cooking or heating sucrose, except for those prepared using ammonium (Class III and IV). Despite some claims that caramel is toxic or carcinogenic, or leads to intestinal problems,[5] the IPCS has found no evidence of carcinogenicity or mutagenicity in its extensive studies.


E 150a is Class I by definition. I don't see any evidence why it should be harmful.

The cancer card is a very tough one to play, and I would be extremely reluctant to use this as an argument against whisky colouring. You'd have to ban all kinds of sweets like toffee and fudge first. A piece of whisky fudge will probably contain a lot more of that allegedly nasty stuff than an entire bottle of E150a coloured whisky.

That may be the case. We've been eating burnt food ever since we've been cooking it ( the Mrs is very good a producing it quite unnecessarily ) and it improves flavour etc. but to me it's an acceptable risk - we have to eat ( and this includes fudge :lol: ). But e150 is just an additive and not an ingredient ( although i accept that the shady organisations tell us it's harmless ).

How can this be necessarily be attributed to caramel colouring? Maybe it can, for all I know. There are so, so many things that affect the taste of whisky.

Of course it can.
Why add to the chances by adding caramel?

But many people (I don't claim to be one) believe they can detect the caramel and who am I to say they can't.

I suspect JM has tasted more whiskies in a year than you have in your lifetime and he is adamant he can tell - he's certainly got a far better palate than me.
So I don't buy the "it has no effect" line.

Again, maybe it has an effect, and I don't think anyone's lying when they say they can taste it. They could, possibly, be mistaken. Or else they're right.

People with integrity can believe lots of things that just aren't true. There are countless myths doing the rounds that can be proved to be untrue.

Charles Maclean talks about the taste map of the tongue - sure we know this doesn't exist. Homeopathy...
