Lactitol

Core Functional Properties

● Soft sucrose-like sweetness with strong compounding adaptability

Sweetness reaches 30-40 % of sucrose, delivering steady, mild sweetness without bitter after-taste or sharp cooling sensation. Blending with high-potency sweeteners or other polyols can boost sweetness without substantial formula revision, enabling easy low-sugar / sugar-free product transformation.

● Low-calorie & low-glycemic with limited metabolic burden

Far fewer calories than sucrose and an extremely low GI value. Slow human-body absorption with barely insulin-dependent metabolism, resulting in modest post-prandial blood-glucose fluctuation. Ideal for diabetics, glucose-sensitive individuals and weight-loss populations.

● Resistance to Maillard browning for superior thermal-processing performance

Its molecular structure discourages Maillard reactions, resisting discoloration under high-temperature boiling, baking and sterilization. Preserves original product colour and is highly favourable for light-coloured bakery goods, white confectionery and dairy products.

● Potent moisturizing & anti-staling capacity to optimize product texture

Excellent water-binding capability effectively locks internal food moisture, inhibits starch retrogradation, delays hardening and moisture-loss brittleness, extends retention of soft mouthfeel and improves shelf-life performance of end-products.

● Mild prebiotic gastrointestinal properties

Low absorption rate in the small intestine; most fraction reaches the large intestine and acts as a prebiotic substrate to selectively stimulate beneficial gut microbiota proliferation and regulate intestinal microecology. It features a higher diarrhoea threshold than sorbitol and mannitol at equivalent dosage levels.

● Non-fermentable by oral pathogenic bacteria for auxiliary dental protection

Oral pathogenic bacteria such as Streptococcus mutans cannot metabolize lactitol to produce organic acids. It reduces dental-plaque formation and lowers enamel-erosion risk, delivering auxiliary anti-caries effects.

Physiologically Modulating Functions

Lactitol is a well-established disaccharide-based polyol combining food-safety credentials with multiple positive intestinal-metabolism benefits:

● Moderated blood-glucose response:

Slow small-intestinal absorption imposes mild stimulation on blood glucose and insulin, avoiding sharp postprandial glycaemic surges and providing safe, gentle sweet-taste solutions for hyperglycaemic populations.

● Prebiotic intestinal regulation:

Most lactitol reaches the colon to selectively boost proliferation of beneficial probiotics, modulate gut microbiota composition and support intestinal health.

● Higher gastrointestinal tolerance threshold:

Compared with sorbitol and mannitol, it causes lower incidence of bloating and diarrhoea at equal dosage, exhibiting good tolerance for general-population daily consumption.

● Low metabolizable caloric intake:

Delivers low available calories. Replacing sucrose directly cuts total product energy and assists weight management.

Product Applications

● Food & Beverage Industry

➢Dairy Products

• Yoghurt & fermented milk: Partially replaces sucrose without disturbing lactic-acid-bacteria fermentation; preserves texture via moisturization and reduces product calorie.

• Milk-based beverages & plant-protein drinks: Gentle sweetness free of cloying notes with stable system behaviour, suited for low-sugar and sugar-free dairy formulations.

• Ice-cream & frozen desserts: Refines ice-crystal structure, enhances melt-resistance and maintains smooth frozen-product mouthfeel.

➢Baked Foods

• Bread, cakes & toast: Powerful water-locking and moisturizing performance inhibits starch retrogradation, sustains long-term soft-moist texture and resists colour development during high-temperature baking.

• Biscuits, shortbread & pastries: Reduces finished-product calorie and modulates texture hardness-softness; outstanding advantages for light-coloured bakery items.

• Meal-replacement baked goods & energy bars: Matches healthy low-sugar positioning and exhibits stable compatibility with dietary fibres and whey protein.

➢Beverages

• Sugar-free tea drinks, sparkling water & bottled functional beverages: Gentle base sweetness with pH tolerance and minimal colour shift during storage.

• Coffee, meal-replacement shakes, oral liquids & solid instant powders: Fast dissolution yielding clear solutions; no antagonistic reactions with vitamins and active functional ingredients.

• Fruit juices, fruit vinegars & acidic drinks: Acid-resistant system; minimal browning after high-temperature sterilization with high flavour-restoration fidelity.

➢Confectionery & Chocolate

• Sugar-free hard candies, gummies, jellies & puddings: Good boiling-moulding performance, low sanding tendency and bright-transparent candy appearance.

• Chocolate & filled candies: Inhibits Maillard discoloration, modifies paste texture and improves storage stability.

• Chewing gums, mint lozenges & throat-soothing candies: Gentle sweet base supporting auxiliary dental care without intense cooling stimulation.

➢Sauces & Condiments

• Salad dressings, tomato ketchup & fruit jams: Does not add extra cloying sweetness; moisturizes and stabilizes systems and delays quality deterioration after opening.

• Barbecue glazes, cold-mixed sauces & light-food seasonings: Gentle sweetening balances complex savoury-sweet-sour flavour profiles for low-fat and low-sugar formulations.

➢Meat Products

• Low-temperature hams, low-fat sausages & surimi products: Mild sweetening and fish-odour masking; does not destroy meat emulsification systems and maintains colour stability during cooking.

● Health-Food & Dietary Supplements

Glycemic-management solid beverages, weight-loss meal-replacement powders, sugar-free compressed candies, middle-aged-and-elderly nutritional supplements, sugar-free children-targeted chewable tablets. Suited for high-end health-oriented formulations featuring low-glycaemic response, gastrointestinal-friendliness and moisturizing properties.

● Pet Food

Sugar-free pet dental-care snacks, nutritional pastes and dental-chewing gums. Improves feed palatability, assists oral care for pets and mites metabolic burdens caused by excessive sugar intake.

● Cosmetics & Personal Care

Toothpastes, mouth-washes: Mild flavour-masking sweet base to improve oral sensory experience. Skin-care creams & skin toners: Moisturizing auxiliary agent optimizing skin feel with no sensitization risks.

● Pharmaceutical Field

Medicinal flavour-correcting excipient for oral tablets, granules and dry suspensions to mask bitter off-notes of active pharmaceutical ingredients. Used in special-medical-purpose formula foods for metabolic and intestinal disorders to satisfy low-sugar dietary requirements for specific patient groups.

● Feed Industry

Feed additive for livestock, aquaculture and companion animals. Enhances feed palatability and feed intake, and assists regulation of animal intestinal health.
