# Upcycled Sargassum Seaweed Ingrdients Florida International University Finds Uses for Sargassum By Kalin Ned | Published 2026-05-06 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/sargassum-seaweed References: [bioengineer.org](https://bioengineer.org/florida-beaches-overrun-by-sargassum-fiu-scientists-discover-novel-food-grade-applications/)  Florida International University researchers have developed a method to extract alginate from Sargassum seaweed. This news is ground-breaking because the method transforms an [invasive marine plant](https://www.trendhunter.com/trends/Bioengineered-pollution-remediation), which routinely floods Florida beaches, into a potential food-grade ingredient. Florida International University's innovation addresses the massive blooms of brown algae that wash ashore, which are the culprits for foul odors, ecosystem harm, and incur high cleanup expenses. The study, published in Food Hydrocolloids, demonstrates that Sargassum seaweed contains significant alginate levels with extraction yields around 45%, positioning the biomass as a possible alternative source for a common food additive used to stabilize and thicken products like ice cream, sauces, and dairy alternatives. The need for further testing and regulatory approval means consumers will not see sargassum-based products immediately, but the promise of a sustainable, locally sourced thickener that simultaneously cleans beaches and creates value offers a compelling reason to pay attention to future product releases.
