一般描述

木糖醇是一种天然存在的五碳糖醇,相当于蔗糖中的甜度。[1]木糖醇可用于制备糖果、口香糖、牙膏和漱口水。木糖醇是一种不依赖胰岛素代谢的低能甜味剂,使其有望成为糖尿病患者的糖替代品。[1][2]木糖醇是一种天然的防龋制剂,不被致龋菌利用,对龋齿有饥饿作用。[3]木糖醇可预防耳炎和上呼吸道感染。商业上,微生物如细菌、真菌和酵母菌通过发酵生产木糖醇。[2]

应用

木糖醇已用于:
  • 作为高效液相色谱的标准品 [1]
  • 分析口腔生物膜上的抗菌活性,[3]
  • 用于热力学数据和密度测量[4]

生化/生理作用

一种人类可以检测到的糖醇甜味剂。半纤维素水解物发酵生产。

Questions

1–2 of 2 Questions  
  1. 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

  2. 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.
