Fucoidan Extracted from Undaria pinnatifida: Source for Nutraceuticals/Functional Foods

Abstract

The importance of fucoidan as a functional ingredient in food, health products, and pharmaceutics is well-recognized due to its beneficial biological effects. Fucoidan is usually extracted from brown seaweeds, including Undaria pinnatifida. Fucoidan exhibits beneficial bio-activity and has antioxidant, anticancer, and anticoagulant properties. This review focuses on the biological activity of U. pinnatifida-derived fucoidan and investigates its structure–activity or fraction–activity relationship. It also describes several fucoidan extracts, along with their claimed anticancer effects. It aims to provide information and thoughts for future research such as the development of fucoidan into functional foods or nutraceuticals.

“…However, fucoidans used in most of these studies were crude fucoidan extracts that contain non‐fucoidan components such as laminaran and polyphenols, which also have bioactivities such as antioxidant activity and may interfere the functional studies of fucoidan. Thus, highly purified fucoidan fractions are required to be used in any biological function studies of fucoidan (Fitton, ; Fitton et al, ; Zhao et al, ).…”

Ultrasound‐Assisted Extraction of Fucoidan from Vietnamese Brown Seaweed Sargassum mcclurei and Testing Bioactivities of the Extract

“…According to previous study carried out on Undaria pinnatifida (U. pinnatifida) to extract fucoidan, while yield of fucoidan extracted by HWE method was 12.9%, that extracted by UAE was 33.0% . The higher extraction yield can be explained because the formation of cavitation by ultrasonic wave degrades brown seaweed cell wall, leading to the acceleration of the extraction of fucoidan …”

First Genome of the Brown Alga Undaria pinnatifida: Chromosome-Level Assembly Using PacBio and Hi-C Technologies

“…The brown alga Undaria pinnatifida (Harvey) Suringar is an economically important kelp species native to the Northwest Pacific and has been extensively farmed as human food in East Asia for more than half a century (Yamanaka and Akiyama, 1993). It is also an important resource for extracting biologically active compounds such as fucoidans which have diverse applications in pharmaceutical and cosmetic industries (Zhao et al, 2018;Yoo et al, 2019). Its annual yield worldwide has been more than two million tons since 2012 (http://www.fao.org/fishery/species/ 2777/en).…”
