The term “degraded carrageenan” is no longer in use among the scientific community, but because many people still refer to poligeenan as “degraded carrageenan,” there are those who mistakenly assume that the two substances are one and the same.

Regardless, the truth is that carrageenan is not poligeenan, and poligeenan is not used in foods. The process used to create poligeenan requires washing seaweed at 194 degrees Fahrenheit for up to 6 hours in an acidic bath with a p H of 1 — similar to battery acid.

Furthermore, this tiny ingredient would not be able to remain in the stomach for a full 6 hours — it would pass through.

And the average acidity of stomach acid is nowhere near harsh enough to turn carrageenan into poligeenan.

It also prevents food waste by stabilizing foods — which means they stay delicious longer without spoiling.

While the word carrageenan may be unfamiliar, this food ingredient is harvested from a natural source we’ve all heard of, seaweed, which is often praised for its many health and wellness benefits.

Carrageenan is an ingredient in many of the foods we eat every day, from cheese to almond milk to jam to salad dressing.

Among other uses, it makes ice cream and yogurt creamy and serves as a vegan alternative to gelatin.

The temperature inside the stomach during digestion is only 99 degrees Fahrenheit.
