Answer 1

these foods are quite potent. While the food is digesting, it has opportunities to give any gas that enters the stomach it’s smell, and if strong enough, this can overcome the smell of stomach acid, carrying the food’s smell back up through your oesophagus. As for why they last so long, this could be due to slow digestion, if a food is in the stomach for longer, your burps will smell like them for longer.
