General description

Starch is a carbohydrate reserve in plants and a major source of energy for humans. In plants, starch is found in chloroplasts of leaf and in the amyloplasts of tuber and seeds. Structurally, starch consists of two major polysaccharides, namely amylose and amylopectin. Both consists of chains of -(1,4)-linked D-glucose residues interconnected through -(1,6)-glycosidic linkages. Potato starch is superior to others, functionally, because of its low lipid level. Nutritional composition of starch comprises of rapidly digestible starch, slowly digestible starch, and resistant starch (RS). Amylases are the starch degrading enzymes. Starch digestibility affects the blood glucose levels and is controlled by factors like carbohydrate contents of foods, nutritional composition of starch and cooking foods. Inhibition of pancreatic amylase is of therapeutic importance for delaying starch digestion, to prevent postprandial hyperglycemia. Food industries use starch as thickening agent.

Application

Starch from potato has been used as a substrate for α-amylase inhibition assay, by use of raw and cooked food samples and aerial parts of Trichosanthes cucumerina Linn, as a substrate to determine SusG activity, in animal gut microbiota activity using DNSA assay.

Questions

1–8 of 8 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

  3. 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
