Galacto-oligosaccharides (GOS) Applications in Chocolate
1.1 What Are Galacare™Galacto-oligosaccharides
Natural Sweetness, Enhanced Performance
Galacto-oligosaccharides (Galacare™GOS) are functional prebiotic oligosaccharides built from galactose units. Structurally, 1 to 7 galactosyl groups are linked to a galactose or glucose molecule, and commercial Galacare™GOS is a complex mixture containing more than 15 effective monomeric components.
Among the three internationally recognized prebiotics, Galacare™GOS is the only oligosaccharide that occurs naturally in breast milk, and it can be utilized by many species of beneficial bacteria in the human gut, earning it the name golden prebiotic.
GOS is a low-molecular-weight soluble dietary fibre with low viscosity and strong moisture retention. It does not bind minerals, has a clean taste with a sweetness of only 20%-40% that of sucrose and a low caloric value, and is highly stable to both acid and heat.
1.2 Health Benefits of Galacare™GOS
Golden prebiotic that efficiently multiplies bifidobacteria
Of the three major prebiotics, Galacare™GOS is the only one naturally present in breast milk, selectively utilized by many beneficial gut bacteria with strong bifidogenic activity to effectively improve intestinal flora composition.
Improved gut environment and constipation relief
Reaches the large intestine intact where it is fermented by probiotic bacteria, promoting short-chain fatty acid production, lowering intestinal pH, inhibiting harmful bacteria, and stimulating peristalsis.
Low-calorie, low-sweetness soluble dietary fibre
Provides gentle sweetness and fibre intake without a heavy energy load, suiting sugar-reduced, weight-control and health-conscious consumers.
Acid- and heat-tolerant with stable activity
Remains intact under pH 3 acidity and temperatures up to 180 degreesC, surviving processing and gastric conditions without adverse effects on mineral absorption.
1.4 Advantages of Galacare™GOS in Chocolate Applications
A clear gut-health proposition
As the golden prebiotic, Galacare™GOS gives chocolate a direct prebiotic and dietary-fibre concept, matching the trend toward functional snacking and everyday health management.
Synergy with live probiotics (synbiotic formulations)
The fat-rich chocolate matrix naturally protects live bacteria through gastric acid while Galacare™GOS serves as food for probiotics, forming a synbiotic product.
Acid- and heat-stable with no processing loss
Stays stable during refining, conching, tempering and in acidic formulations without decomposition, loss of activity, or affecting chocolate setting and gloss.
Improved texture and moisture retention
Low viscosity and easy dispersibility add no processing burden, while strong moisture retention delays drying and hardening of fillings.
Low sweetness and clean flavor
Clean sweetness has no bitter aftertaste or cooling sensation and does not mask cocoa or fruit notes, suiting dark, milk and fruit-flavoured chocolates.
Label-friendly with high consumer recognition
The image of a breast-milk oligosaccharide golden prebiotic is widely recognized from long use in infant and functional foods, giving it high consumer acceptance.
