Research - question about d-glucose, and dextrose

    I can't find a place to "create a topic" in the Research forum, so am posting here.

    Have just read the article in Wikipedia on glucose - and am confused (OK, OK, I know).

    It says that glucose syrup is just another name for corn syrup, and that glucose syrup is extracted from corn starch.  David lists glucose syrup as good, corn syrup as bad.

    I presume that the stuff we call glucose syrup (found in the cooking isle) is made from dextrose, and is different to the stuff they use in the US?   

    What is dextrose made or extracted from?  

    What exactly is corn syrup (not to be confused with HFCS) - and how does it differ from glucose syrup?

    Dextrose is another name for D-glucose which is just to differentiate its physical properties from L-glucose, the other form. Our bodies only use D-sugars. From the wikipedia article, glucose/dextrose is made by 'chopping up' the long chains of glucose molecules that are stuck together to make corn starch. From what I can tell, corn syrup=glucose syrup and is different to the HFCS which is up to 55% fructose and made by enzymatic reaction of some of the glucose in the corn syrup to fructose. There is some confusion regarding whether there is any fructose present in normal glucose syrup at all, so I'm not 100% clear on that. I am assuming that glucose syrup is just glucose molecules derived from corn starch and made into a syrup, without any fructose involved.

    I hope this helps. Anyone else know for sure?

    Hi,

    David F put a reply to the same question on his new topic "Glucose Syrup." Here's the reply he posted with more information:

    I have just received a response from Queen Fine Foods P/L regarding my above query. Their representative, in a display of first class service, has informed me that Queen brand glucose syrup contains only glucose and definitely does not contain fructose. I bought the jar from Coles. It was near cake making thingys, adjacent to vanilla essence etc.
     
    It's easy to get the two confused. I have had to read Sweet Poison several times because there's so much information in it, and it helps motivate me to keep off sugar. Basically, the U.S. found that they could extract a sugar substitute from corn- which grew better and more cheaply. They call this substitute High Fructose Corn Syrup, and they use it in everything. Australia had good sugar crops, so we use sugar in everything. Both HFCS and sugar are similiar in fructose-glucose content and have the same effect on our bodies. I have only seen HFCS in one U.S. product on Australian shelves- it was  a pancake syrup and clearly labelled as HFCS so I didn;t buy it.
     
    As you can see from David F's entry, Australian glucose syrup is glucose, so I guess they extracted just the glucose molecules from the corn. I've noticed it in my gluten free products, and it has been labelled "glucose syrup-from corn," for years, and Coeliacs like me have investigated it to be a pure, highly processed product.
     
    Maybe that means the Amercians get both fructose and glucose out of corn. Well, we have manufactured products which have lactose extracted out, fat extracted out, yeast extracted out... they must be able to pull anything out that they want to.
