Food Grade Stachyose Powder – Functional Prebiotic Ingredient for Healthy Foods & Drinks

Stachyose is a naturally occurring tetrasaccharide with the molecular formula C24H42O21, the relative molecular weight is 666.59. Its structure consists of two galactose, one glucose and one fructose. It is a non-reducing functional oligosaccharide. Stachyose is not decomposed by human gastrointestinal digestive juice and belongs to soluble dietary fiber.

• White powder in appearance, fresh taste without peculiar smell.
• Sweetness is 22% of sucrose sweetness.
• Easily soluble in water (130g/20ºC); insoluble in organic solvents like ether and ethanol.
• Lower moisture retention than sucrose, but higher than high fructose syrup.
• Osmotic pressure similar to sucrose.
• Melting point of 101ºC; anhydrous stachyose melting point is 167ºC~170ºC.
• Non-reducing properties.

1. Proliferate Bifidobacteria: Stachyose effectively regulates intestinal flora balance. Bifidobacteria preferentially consume stachyose over other sugars, allowing for direct proliferation of beneficial bacteria.

2. Relieve Constipation: As a small molecule water-soluble dietary fiber, it produces short-chain fatty acids in the large intestine to enhance intestinal function and absorb water to alleviate diarrhea.

3. Liver Protection: Reduces ammonia production from amino acid decomposition, avoiding ammonia poisoning and fighting liver cirrhosis.

4. Immunomodulatory Function: The α-1,6-galactose structure helps prevent pathogen infection and neutralize toxins while improving human immunity factors.

5. Lead Removal: Reduces food residue residence time and inhibits lead absorption by promoting B vitamin synthesis.

6. Metabolism Regulation: Significant in improving glucose and lipid metabolism, reducing fasting blood glucose and total cholesterol levels.

• Flora Balance: 0.5~3 g per day for 15-30 days.
• Constipation Relief: Adults: 5~10 g/day; Children: 1~3 g/day for 1-7 days.
• Poultry Feed: 0.5~1.0% in ration.
• Pig Feed: 0.8~1.0% in ration.
• Aquaculture: 0.8~1.25% in feed.
