Are spicy hot pot soup bases adding phthalates to your meal?
Often yes. Oily packaged hot pot bases test high for DBP and DEHP from plastic packaging.
What's actually in it
Packaged hot pot bases are typically a brick or pouch of chili oil, spices, and beef tallow sealed in plastic. The plastic uses DBP and DEHP as softeners. Both phthalates love fat, so they migrate from the pouch into the oily base. Cooking with that base then mixes the chemicals into the broth and eventually into the meat and vegetables.
Loose-leaf spice mixes and bone broth blocks have less of the issue.
What the research says
A 2026 study in Toxics ran a hybrid model on phthalate levels in commercial hot pot bases. DBP and DEHP exceeded safe daily intakes for frequent eaters, especially kids and pregnant women. Spicier and oilier bases tested worse.
The team called regular hot pot a real exposure path that nobody on dietary advice has been talking about.
Make hot pot at home with fresh aromatics: ginger, garlic, scallions, dried chilies, and sesame oil. Use a steel pot and steel ladle. Skip the chili oil packet that comes with hot pot kits, or transfer the base into a glass jar before cooking with it.
