General description

Guar is extracted from the seeds of Cyamopsis tetragonoloba. It contains polysaccharides of galactomannans. Guar is used in thickening dye solution, production of paper and as a primary gelling agent in water-based slurry explosives. It acts as a fiber deflocculent and dry-strength additive and serves as an additive to dynamite for water blocking. Guar is used as a stabilizer, emulsifier and thickener in food products. It lowers cholesterol and glucose level. Guar aids weight loss and obesity prevention.

Application

Guar has been used:
  • to maintain viscosity during in vitro starch digestion assay
  • to reduce the thinning rate of agarose gel[1]
  • to study its effects on establishing 3D-like neural networks on microelectrode arrays (MEAs)

Biochem/physiol Actions

Guar gum has been shown to have numerous beneficial effects including improved glucose tolerance and attenuation of diabetic nephropathy.

Other Notes

Guar gum is isolated from the endosperm of the guar or gavar bean.

Questions

1–4 of 4 Questions  
  1. How can I determine the shelf life / expiration / retest date of this product?

    1 answer
    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/418/501/product-dating-information-06-25-mk.pdf

  2. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer
    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf
