Question:
The carbohydrates responsible for causing flatulence are -
The carbohydrates responsible for causing flatulence are -
Show Hint
To reduce the flatulence-causing oligosaccharides in beans:
- Soak them in water and discard the soak water before cooking (as these sugars are highly water-soluble).
- Germination (sprouting) also activates endogenous \(\alpha\)-galactosidases, naturally breaking down these oligosaccharides.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
Humans lack certain digestive enzymes required to break down specific complex oligosaccharides found in legumes and beans.
Step 2: Detailed Explanation:
- Raffinose (trisaccharide) and Stachyose (tetrasaccharide) are \(\alpha\)-galactosyl oligosaccharides abundant in beans, lentils, and peas.
- The human gastrointestinal tract lacks the enzyme \(\alpha\)-galactosidase necessary to hydrolyze the \(\alpha\)-(1\(\rightarrow\)6) glycosidic bonds of these sugars.
- Consequently, these oligosaccharides pass intact and undigested through the small intestine into the large intestine.
- In the colon, the anaerobic intestinal microflora ferment these sugars, producing significant quantities of carbon dioxide (\(\text{CO}_2\)), hydrogen (\(\text{H}_2\)), and methane (\(\text{CH}_4\)) gases, leading to abdominal flatulence and bloating.
Step 3: Final Answer:
The carbohydrates responsible are Raffinose and Stachyose, which corresponds to option (C).
