Galactooligosaccharide /GOS
What is the difference between GOS and probiotics?
GOS is a prebiotic: it is the "food" of probiotics, which is not a live bacterium and will not be digested by the human body. It directly reaches the large intestine and is utilized by beneficial bacteria.
Probiotics: live microorganisms that directly supplement beneficial bacteria in the intestine.
The two can be used in synergy (i.e. Synergetic) for better results.

Q1:What are the main application areas of GOS?
A: Infant formula food (core application)
Dairy products (yogurt, milk, dairy beverages)
Dietary supplements (capsules, powders, tablets)
Functional foods (baked goods, nutrition bars, candies)
Special medical formula food and pet food.
Q2:Is GOS stable in food processing?
A: Very stable. GOS has excellent heat and acid resistance, can withstand high temperatures above 120 ℃ for sterilization, and can maintain stability in the pH range of 3-7. Therefore, it is suitable for various food processing techniques, including fermentation, baking, and sterilization treatment.
Q3:Is GOS a vegetarian source?
A: Traditional GOS uses lactose as its raw material, which is derived from milk and therefore does not belong to strict vegetarianism (Vegan). But currently, there are studies using plant-based substrates or non dairy raw materials to produce GOS to meet the demand of the vegan market.
