How can I determine the shelf life / expiration / retest date of this product?
1 answer-
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.

Hello, is it possible to get full specifiaction of this product? (galacturonic acid content, % of esterificatona etc?) Is it pure pectin, or does it contain any stabilisers or sugars?
1 answer-
The % esterification specification for this item is 50 - 75%, Specific impurities have not been identified. The material is tested for appearance, specific rotation, solubility, moisture content, residue on ignition, degree of esterification, and infrared spectroscopy for verification of identity. The tests, specification for each, and lot specific results are reported in the product Certificate of Analysis. Please see the link below to access a sample or lot specific Certificate:

Is this pectin low-methoxy or high-methoxy, and does it gel in the presence of calcium cations?
1 answer-
This product's methoxy content is not tested. Pectin can gel in the presence of Calcium, whereby the Calcium ions act as a cross-linking agent, helping to stabilize the gel structure by forming bridges between pectin molecules. This is particularly true of high methoxy pectin. However, the gelling properties of this product are also not tested.

How is shipping temperature determined? And how is it related to the product storage temperature?
1 answer-
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
