俄罗斯采购需求：食品添加剂、产品

I'm interested in procuring 2 kg of high-purity Stachyose with a purity level of 99%. To ensure it meets our specifications, could you please share detailed information about potential impurities, particularly the presence of glucose and sucrose? Additionally, if there are any available certificates of analysis or relevant documentation regarding the purity and impurity levels, I would appreciate your prompt sharing of those as well. This will help us in making an informed decision. Thank you!
