Hair-Made Soy Sauce: An Update
Status: Gross news

Back in January 2004 I posted a
short entry about a factory in China that had been caught making soy sauce out of human hair. I also mentioned the incident in
Hippo Eats Dwarf (p.76). Now
more gruesome details have emerged, published in the
Internet Journal of Toxicology (link via
Boing Boing):
In late 2003, there was an alternatively produced soy sauce named "Hongshuai Soy Sauce" in China. The soy sauce was marketed as “blended using latest bioengineering technology” by a food seasoning manufacturer, suggesting that the soy sauce was not generated in a traditional way using soy and wheat. The Hongshuai Soy Sauce was sold at a relatively low price in Mainland China and became very popular among the public. The people found its taste to be similar to other brands. Because of its low price, many catering services in schools and colleges decided to use this new product.
An investigation led by TV journalists then revealed why the soy sauce was so cheap. It was being manufactured from an amino acid powder (or syrup) bought from a manufacturer in Hubei province:
When asking how the amino acid syrup (or powder) was generated, the manufacturer replied that the powder was generated from human hair. Because the human hair was gathered from salon, barbershop and hospitals around the country, it was unhygienic and mixed with condom, used hospital cottons, used menstrual cycle pad, used syringe, etc. After filtered by the workers, the hair would then cut small for being processed into amino acid syrup. The technicians admitted that they would not consume the human-hair soy sauce because the dirty and unhygienic hair was used to make amino acid syrup. A quality monitoring staff also revealed that though the hair may not be toxic itself, it definitely consisted of bacteria and other micro-organisms.
Lovely. But what the article doesn't mention, but which I believe to be true, is that soy sauce isn't the only food product made out of this cheap hair-made amino acid powder. The stuff is also sold in large quantities to the
bakery industry which uses it as a source of L-cysteine to make dough softer and more elastic. Think about that next time you're chewing on a bagel.

"Because the human hair was gathered from salon, barbershop and hospitals around the country, it was unhygienic and mixed with condom, used hospital cottons, used menstrual cycle pad, used syringe, etc."
I thought that the trash from hospitals was incinerated? Anyway, is there really that much hair in it? I would think that the biggest mass of it is used bandages, tissues, rubber gloves, tubes, and other single-use instruments, and of course lots of empty drug packs. Oh, by the way, why would hairdressers and doctors use so many condoms?

There would be hair in it, probably from shaving patients for surgery.

Thanks a lot, Alex. I was just eating a bagel when I read that!

Most Top Ramen and other Asian noodles have the human hair stuff in it. No big surprise here.

Glad I read this, I was about to donate my hair to some kid with cancer, but now I can sell it for food use and host a not-so-scary-yet-still-nasty hannible lecter dinner party.

It seems that ATY Lee is not all he seems. The original article in the Internet Journal of Toxicology ( vol2 No 1) has been withdrawn by the publisher.
Why? Don't know. However, whether its true or not is arguable. Recetly in Austraiua there has been discussion of garlic from China gorown it is alleged on human sewage, bleached, treated with growth suppressants etc. We import 90,000 TONNES a year. What the USa imports is way more. I'd say buy local and buy local soy sauce.
