crystalline fructose

Crystalline fructose is a refined monosaccharide sweetener derived primarily from corn or sugar cane through enzymatic hydrolysis and crystallization. It is chemically identical to the fructose found naturally in fruits and honey, consisting of a six-carbon sugar molecule (C₆H₁₂O₆) in its D-form. The production process involves converting glucose (from starch hydrolysis) into fructose using the enzyme glucose isomerase, followed by separation and crystallization to yield white crystals resembling granulated sugar. Pure crystalline fructose contains 99%+ fructose content and is notably sweeter than table sugar (sucrose), with a sweetness intensity approximately 1.2 to 1.7 times greater than sucrose, while providing a clean, fruity flavor profile without aftertaste.

Crystalline fructose differs from high-fructose corn syrup (HFCS) in form and concentration: while HFCS is a liquid containing 42-55% fructose mixed with glucose, crystalline fructose is a solid containing nearly pure fructose.

Crystalline fructose is utilized as a bulk sweetener in beverages, baked goods, confectionery, and processed foods where its higher sweetness intensity allows for reduced quantities. Its lower glycemic index compared to sucrose makes it attractive for diabetic-friendly formulations, though nutritional profiles should be verified by individual products. It dissolves readily in liquid applications and may be used in a 1:0.6 to 1:0.75 ratio in place of sucrose in many recipes, though it can produce darker browning in baked goods due to enhanced Maillard reactions. Crystalline fructose is commonly found in functional beverages, energy bars, low-calorie desserts, and specialty dietary products.
