For procurement managers and R&D scientists in the food, beverage, and pharmaceutical industries, identifying reliable suppliers for key ingredients is paramount. D-Xylose (CAS 58-86-6), a natural sugar with significant health benefits and functional properties, is one such ingredient. This guide aims to provide B2B buyers with essential information on sourcing D-Xylose, focusing on quality, price, and the advantages of partnering with a reputable manufacturer.

D-Xylose, often referred to as wood sugar, is a pentose sugar derived from hemicellulose found in plants. Its key attributes include being a non-caloric sweetener, a prebiotic that supports gut health, and an enhancer of calcium absorption. These benefits make it a sought-after ingredient for products targeting diabetic consumers, health-conscious individuals, and those looking for improved digestive and bone health.

When evaluating D-Xylose suppliers, quality is the foremost consideration. Key quality indicators typically include:

• Purity: Look for specifications typically above 98.5%, often meeting BP/USP/EP/FCC standards. Higher purity ensures consistent performance and safety in finished products.
• Appearance: D-Xylose should be a White crystalline powder, free from foreign matter.
• Loss on Drying & Residue on Ignition: These parameters indicate the product’s moisture content and inorganic impurities, respectively. Low values are desirable.
• Specific Rotation: This optical property is a characteristic of pure D-Xylose and should fall within a specified range.
• Heavy Metals & Arsenic Content: Strict limits for these contaminants are critical, especially for food and pharmaceutical applications.

As a buyer, understanding these specifications will help you compare offerings and ensure you are receiving a product that meets your application's requirements. It is also advisable to request Certificates of Analysis (CoA) from potential suppliers.

Regarding price, several factors influence the cost of D-Xylose:

• Raw Material Availability and Cost: Fluctuations in the supply and price of hemicellulose-rich biomass can impact production costs.
• Manufacturing Process: The efficiency and scale of the extraction and purification processes play a role.
• Purity and Grade: Higher purity grades and specific certifications (e.g., Kosher, Halal) may command premium pricing.
• Order Volume: Bulk purchases typically benefit from economies of scale, leading to lower per-unit costs.
• Logistics and Shipping: Costs associated with transportation, customs, and Incoterms can vary.

To secure competitive D-Xylose pricing, engaging with multiple suppliers and negotiating terms based on your projected order volumes is recommended. Inquiring directly with manufacturers or their authorized distributors in China can often yield the best results.
