    Cross-Contamination and Grain Processing Equipment

    Reviewed and edited by a celiac disease expert.

    From Brian Kuhl (Open Original Shared Link) of Dantec Corp. - Waterloo, ON, Canada

    (Celiac.com 06/12/2000) I work for a company that supplies computerized control equipment to the grain handling industry. I have been in grain elevators across Canada and the US. I have limited experience with flour mills. Virtually all grains and bean crops are contaminated, their is little economic incentive for the elevators to fix this problem as most often a small amount of a less expensive crop is contaminating a more expensive one. I have even seen elevators intentionally contaminate certain high price commodities (i.e. bean crops), though to be fair most of this is removed by cleaning equipment at the mills. And if the allowable limits are exceeded the train-car or transport-truck will be rejected by the mill and sent back to the elevator at a considerable expense. Since all grains are moved by the same equipment and this metal equipment is forever wearing out allowing small amounts of amounts of grain to spill into the holding area for another. Also the same equipment is used to move different grains, it is possible for a truck carrying one grain to dump into the same elevating equipment that was just used to carry another, a certain amount of residue is left in even the most well maintained equipment.

    As someone with mild wheat intolerance (I have never been tested for celiac), I do not worry about this. The intolerance is not an allergic reaction, the miniscule amounts of gluten I would encounter from this sort of thing is miniscule, and I have never had a symptomatic reaction to any oat product. But I am forever reacting to restaurant food that has been dusted with flour, or potato soups that have been thickened with flour. My worst experience is when I was served cream-of-wheat as oatmeal.

    Very informative with very interesting links. While writing a thought came to me the other day that for those who are intolerant to gluten, as opposed to being allergic, it would be helpful, where appropriate, if both the approximate concentration and the type of gluten were to be displayed on the container.

     

    Thank you for what you are doing

    The chance of contamination can be reduced greatly. I buy blue corn from a grain elevator in San Jon, NM, that handles only that grain, and no wheat is grown in the area. So the farm combines and trucks do not handle wheat. I mill the corn on a dedicated mill, and offer the cornmeal for sale at Santa Fe Farmers' Market. I once found a half of a legume seed (maybe a pea) in the corn, but in a 50# bag, what matter?

    So, what is the name of the grain elevator that has the blue corn, and is the corn non-GMO? Thanks.

    Scott Adams was diagnosed with celiac disease in 1994, and, due to the nearly total lack of information available at that time, was forced to become an expert on the disease in order to recover. In 1995 he launched the site that later became Celiac.com to help as many people as possible with celiac disease get diagnosed so they can begin to live happy, healthy gluten-free lives.  He is co-author of the book Cereal Killers, and founder and publisher of the (formerly paper) newsletter Journal of Gluten Sensitivity. In 1998 he founded The Gluten-Free Mall which he sold in 2014. Celiac.com does not sell any products, and is 100% advertiser supported.

    The connection with wheat (and rye and barley) wasnt recognized until the 1950s - (a)nd it wasnt until the 1960s that intestinal biopsies began to become commonly used in the diagnosis of celiac disease. With regard to the harmfulness of barley malt, the situation is complicated. I will give you my best shot with the qualification that the ideal experiments have not been done and a definitive statement is not possible at this time.
    Because barley malt is made from barley grain that has been...

    Celiac.com 01/14/04 – German researchers have developed a new test to determine the level of gliadin, the portion of gluten that is toxic to celiac patients, in foods. This new technique is called immunopolymerase chain reaction (iPCR), and it utilizes immunological detection of gliadin by a monoclonal antibody R5 conjugated when an oligonucleotide is amplified by PCR. The technique yields a "30-fold above the level reached by enzyme immunoassay" in laboratory tests, and it detects concentrations in food "as low as 0.16 ng/ml corresponding to 16 microgram gliadin/100 g food or 0.16 ppm (corresponding to 0.25 g of food extracted in 10 ml of solvent and 25-fold dilution of the extract prior to analysis)." This is the first time that this highly s...

    Celiac.com 10/02/2008 - Whole grains are good sources of B-Vitamins and minerals such as calcium, iron, magnesium, and selenium, but one of their most important nutritional benefits is the fiber they bring to our diets.  Whole grains such as wheat, brown rice, and oats include both soluble and insoluble fiber.  Soluble fiber is easy to remember – it is water soluble, and as such can be assimilated into the body, where it plays an important role in blood sugar regulation and cholesterol balance.   Soluble fiber also helps provide a sense of fullness or satiety.  Insoluble fiber is - you guessed it - insoluble in water, and is not assimilated into the body, but passes through the digestive tract and is eliminated.  That does not mean insoluble fiber has a less important nutritional role to...

    Celiac.com 09/28/2010 - Buckwheat-enhanced gluten-free breads taste better than regular gluten-free breads, and have properties that may benefit people with celiac disease, according to a new study.
    Moreover, buckwheat-enhanced gluten-free flour could be used to create high quality, antioxidant rich bread products that benefit people with celiac disease and offer new market possibilities, says the team behind the study, M. Wronkowska, D. Zielinska, D. Szawara-Nowak, A. Troszynska, and leader M. Soral-Smietana of the Polish Academy of Sciences.
    Soral-Smietana notes that buckwheat's mineral content and antioxidant activity make it ideal for new buckwheat-enhanced gluten-free breads. Buckwheat flour contains high-quality proteins, and is rich in antioxidants and minerals such as, flavonoids...
