A method for preventing crystal maltitol from caking in storage, comprising: detecting a temperature and a humidity of a dried crystal maltitol on-line in real time, an on-line temperature and humidity meter being configured to set a sieving and packaging treatment condition, a redrying treatment condition, and an aging treatment condition; performing a sieving and packaging treatment on the crystal maltitol whose temperature and humidity satisfy the sieving and packaging treatment condition, performing a redrying treatment or an aging treatment on the crystal maltitol whose temperature and humidity satisfy the redrying treatment condition or the aging treatment condition; detecting a temperature and a humidity of the crystal maltitol after the redrying treatment or the aging treatment, and performing the sieving and packaging treatment on the crystal maltitol whose temperature and humidity satisfy the sieving and packaging treatment condition, or else continuing with the redrying treatment or the aging treatment.

The present disclosure relates to a method for preparing liquid maltitol and liquid polyols from a raffinate including maltitol. The method comprises the following steps: obtaining a hydrogenated liquid by hydrogenating a pre-treated raffinate including maltitol, obtaining a post-treated liquid by post-treatment of the hydrogenated liquid to remove impurities, obtaining a dilute liquid and a concentrated maltitol solution by membrane-separation of the post-treated liquid, and using the dilute liquid as the liquid polyols, and obtaining the liquid maltitol by mixing the concentrated maltitol solution with a prepared maltitol solution with a maltitol content of over 50%, wherein the liquid maltitol has a maltitol content greater than or equal to 50% and meets a standard. Before the membrane separation process, the present disclosure reduces the reducing sugar content in the liquid by hydrogenation to lower the risk of yellowing during the process and to improve the quality of the final product.
