Products Description
Crystalline Fructose,often referred to as high-purity fructose, is a naturally occurring monosaccharide or simple sugar. It is structurally an isomer of glucose but possesses unique chemical and physical properties. In its pure form, it appears as a white, odorless, crystalline or crystalline powder. It is highly soluble in water and ethanol.

Key physical attributes include a melting point between 103–105°C. A defining characteristic is its exceptional sweetness—Crystalline Fructose is typically 1.3 to 1.8 times sweeter than regular sucrose (table sugar), making it the sweetest of all naturally occurring sugars. It is found in natural sources like honey, fruits (such as apples and berries), and certain vegetables (e.g., Jerusalem artichokes and chicory).
Major Advantages and Functional Properties of Crystalline Fructose：
Its distinct functional profile offers significant benefits over other sweeteners:
High Sweetness Intensity: Allows for reduced usage to achieve the same sweetness, potentially lowering caloric content and ingredient costs in formulations.
Low Glycemic Index (GI): It has a lower impact on blood glucose levels compared to glucose or sucrose, making it a consideration for specific dietary products.
High Osmotic Pressure & Low Water Activity: Enhances microbial stability in certain products, contributing to shelf-life extension.
Flavor Enhancement: Particularly effective at boosting fruit and chocolate notes while masking undesirable bitter aftertastes of some high-intensity sweeteners or functional ingredients.
Humectancy (Moisture Retention): It attracts and retains moisture, helping to prevent products from drying out, which is crucial in baked goods and confectionery.
Freezing Point Depression: It significantly lowers the freezing point, improving texture and scoopability in frozen desserts like ice cream and sorbet.
Maillard Reaction Participation: It browns readily during heating, contributing to desirable color and flavor development in baked goods.
Wide-Ranging Industrial Applications
Crystalline Fructose's versatility makes it a preferred choice across multiple sectors beyond simply replacing sucrose.
1. Food & Beverage Industry
Beverages:
Sports & Energy Drinks: Its rapid energy uptake (via a different metabolic pathway than glucose) and clean sweetness profile are ideal.
Ready-to-Drink (RTD) & Powdered Drinks: High solubility ensures clear solutions and quick dissolution in instant beverage mixes.
Low-Calorie/Reduced-Sugar Drinks: Synergizes with other sweeteners to reduce overall sweetener content while maintaining palatability.
Fruit Juices & Cordials: Enhances natural fruit flavors and provides a balanced sweetness.
Dairy & Frozen Desserts:
Ice Cream & Sorbet: Improates texture, reduces iciness, and provides a smoother mouthfeel and superior flavor release in cold conditions.
Yogurts & Dairy Drinks: Contributes sweetness without overpowering delicate dairy flavors.
Bakery & Confectionery:
Breads, Cakes, & Cookies: Promotes browning, retains moisture for longer softness, and enhances flavors.
Hard Candies & Gummies: Its high sweetness and solubility are advantageous; its hygroscopic nature must be managed in hard candy production.
Chocolate & Coatings: Works well in sugar-free or reduced-sugar chocolate formulations.
Other Food Products:
Jams, Jellies, & Fruit Preparations: Provides sweetness and helps control water activity.
Cereals & Nutrition Bars: Serves as a binding agent and sweetener in granola and snack bars.
2. Pharmaceutical & Nutraceutical Industries
Syrups & Elixirs: Acts as a sweetener and flavor masker for pediatric and adult medicinal syrups, improving compliance.
Lozenges & Chewable Tablets: Provides a pleasant, quick-dissolving sweet taste.
Nutraceutical Powders & Health Supplements: Used in protein powders, meal replacements, and vitamin mixes for its sweetening and carrier properties.
3. Personal Care & Cosmetic Industry
Skincare Products: Its humectant properties help hydrate and soften skin in lotions, creams, and masks.
Oral Care: Used in some toothpastes and mouthwashes for its sweetening effect without promoting cavities to the same extent as sucrose.
4. Other Industrial Uses
Animal Feed & Pet Food: Incorporated as a palatability enhancer.
Tobacco Processing: Occasionally used as a moisturizing agent and flavor carrier in tobacco products.
Key Considerations of Crystalline Fructose for Use
Metabolic Health: While it has a lower GI, excessive consumption of any added sugar, including fructose, should be avoided as part of a balanced diet. The metabolic effects of high-fructose corn syrup (HFCS) and pure Crystalline Fructose are distinct and should not be conflated in product messaging.
Formulation: Its high hygroscopicity requires careful packaging and handling to prevent caking. Its intense sweetness often necessitates recipe adjustments when substituting for sucrose.
Market & Sourcing Information
Crystalline Fructose is produced to meet various international food-grade standards (e.g., GB/T 26762-2011 in China, FDA GRAS status in the USA).
