Crystalline fructose is a nutritive sweetener derived from corn that offers a fast sweetness onset and clean finish in food and beverage formulations. With fructose purity levels of 99.5% or higher, it delivers consistent sweetness performance while helping mask the aftertaste of high-potency sweeteners like stevia and monk fruit.
For kosher food manufacturers, crystalline fructose is a practical sweetener choice because it is widely available with recognized kosher certification. However, buyers should still verify certification details for each supplier and lot to maintain full compliance.
Kosher Status of Crystalline Fructose
Crystalline fructose produced by major manufacturers such as Tate and Lyle (marketed as KRYSTAR) holds Orthodox Union (OU) kosher certification. The product is certified kosher for year-round use, though it is typically not certified kosher for Passover due to its corn-based origin, which falls under the kitniyot category observed by Ashkenazi communities.
The corn-based production process involves enzymatic conversion of corn starch to fructose, followed by crystallization and purification. Each step must comply with kosher standards, and the certifying agency audits the facility to confirm that no non-kosher processing aids or shared equipment compromise the product’s status.
Technical Specifications for Food-Grade Product
Commercial crystalline fructose must meet strict quality parameters. According to published specifications, key benchmarks include fructose content of 99.50% minimum, moisture at or below 0.06%, and color no greater than 30 RBU. Sulfur dioxide must remain below 9.0 ppm, and heavy metals below 5.0 ppm.
Microbial standards require total plate count under 200 CFU/g and osmophilic mold and yeast each below 10 CFU/g. The product complies with FDA regulation 21 CFR 182.1, which classifies fructose as Generally Recognized as Safe (GRAS). It is also suitable for vegetarian and vegan diets.
Applications in Food and Beverage
Crystalline fructose works well in bakery products, beverages, and confections where a clean sweetness profile is needed. KRYSTAR 300 offers a medium granulation suited for dry blending, while finer grades dissolve quickly in liquid applications.
One of its most valuable functions is as a sweetness profile balancer. When combined with stevia, erythritol, or other natural-origin sweeteners, crystalline fructose rounds out the flavor and reduces lingering aftertaste. This makes it a popular choice in reduced-sugar beverage formulations that still need appealing taste.
Sourcing Considerations for Bulk Buyers
Crystalline fructose is available from multiple global suppliers, including manufacturers in the United States, Europe, and China.
When requesting quotes, confirm that the supplier provides lot-specific kosher certificates and a full certificate of analysis covering all parameters listed above. Standard packaging is 50 lb bags, with bulk quantities available for large-scale food manufacturing operations.
