Instead of explaining it myself, I will quote someone who is a lot more knowledgable than me.
"Lets talk more about this soy protein that is in the bar. All soy based
Protein Bars and every single "pre packed
Protein Bar" for that matter have one thing in common. They all contain an ingredent known as soy lecithin
What is soy lecithin?
In the early 1900***8217;s, the yet to be named ***8217;soy lecithin***8217; was just a waste product produced during the ***8220;degumming***8221; process of soybean
oil. By 1908 the soy bean crushing and soy
oil refining companies had expanded and they were having trouble disposing of the large amounts of foul smelling, fermenting waste product. Soy plants in Germany decided to name this waste product ***8217;soy lecithin***8217; and looked for ways to utilize it. By 1939 scientists had found more than 1,000 different ways to use soy lecithin.
It***8217;s important to note that solvents are used during the ***8220;degumming***8221; process of soybean
oil, so soy lecithin itself is likely to contain chemical solvents
What is the name of the chemical used for the degumming process?
Hexane!!!!!
Remember that name Hexane!!
The "natural" soy protein used in
Protein Bars today is bathed in a toxic, explosive chemical solvent known as hexane. Hexane is used to process nearly all conventional soy protein ingredients and edible oils
and is prohibited when processing organic foods like that found in Better
Protein Bars.
Hexane is a neurotoxic chemical that poses serious occupational hazards to workers, is an environmental air pollutant, and can contaminate food."
All soy proteins isolate used to make
Protein Bars are made using hexane baths.ALL OF THEM!!! If its in a
Protein Bar, and its soy, it was given a hexane bath!!" -needtogetaas.
So, yes I would not like to be putting that crap into my body....
