Research & Science

This page summarises, in plain language, what peer-reviewed literature says about resistant starch and green banana — the science behind our ingredient. It is written for formulators and buyers, not as medical advice, and uses market-safe wording.

What Is Resistant Starch?

Resistant starch (RS) is starch that escapes digestion in the small intestine. Type-2 RS occurs naturally in raw green bananas and raw potatoes. Because it arrives in the colon intact, gut bacteria ferment it, producing short-chain fatty acids such as butyrate — a preferred energy source for the cells lining the colon. This is why RS is studied as a prebiotic fibre.

Processing matters: heat and moisture can convert RS2 back to digestible starch. HIVAS dries at controlled low temperatures specifically to protect RS2 content.

A Note on Claims

HIVAS supplies a food ingredient. Regulatory frameworks (EFSA, FDA and others) restrict disease-related claims for foods; the wording on this site intentionally stays within structure/function language. Buyers are responsible for approved claims on finished products in their markets, and our team can share the underlying literature on request.
