Can phthalates in hot pot seasoning packets migrate into your food?
Yes. Lab testing found DEHP and DBP phthalates in hot pot base products at levels that exceed safe daily intake for regular consumers.
What's actually in it
Hot pot seasoning bases are oily, fatty products packaged in flexible plastic pouches. These pouches contain phthalate plasticizers like DEHP and DBP that keep the plastic soft and flexible. Fat-soluble chemicals love to migrate from plastic into oily food. The longer the seasoning sits in the pouch, the more phthalates dissolve into it.
Hot pot is boiled for extended periods, and the seasoning base makes up a large portion of the broth. Everything you dip in the pot picks up phthalates from the contaminated broth.
What the research says
A 2026 study in Toxics tested hot pot base products for phthalate contamination and calculated health risks for consumers. The results showed DEHP and DBP in multiple products, with some samples exceeding the tolerable daily intake (TDI) for people who eat hot pot regularly.
The oily nature of hot pot seasoning made it especially effective at extracting phthalates from packaging. Products with higher fat content had higher phthalate levels. The risk was highest for frequent hot pot eaters who consume it weekly or more.
Making your own hot pot broth from scratch avoids the packaged seasoning entirely. If you use packaged bases, transferring the seasoning to a glass container before storage and choosing brands that use glass jars or aluminum-lined packaging can help.
