“…As can be seem in Table 2, as was described previously for brown seaweeds, administration of red seaweeds or seaweed-extracted polysaccharides resulted in an increase of SCFA production, stimulating of beneficial bacteria grown such as Lactobacillus [86] or Bifidobacterium [57,94,107], whereas inhibited the growth of potentially pathogen bacteria [57,86]. It was also reported red seaweeds activity on the prevention of naproxen-induced gastrointestinal damage [106].…”

“…The most relevant results obtained from the investigation of red seaweeds effect on GM can be found in Table 2. In this table, results about the prebiotic effect of red seaweed species from genus Acanthopora [86], Gracilaria [105,106], Kappaphycus [107], Euchema and Grateloupia [10], Chondrus [57], Gelidium [94], or Osmundea [88] were included.…”

“…As described by Ramnani et al [94], low-molecular-weight agarose exerted a prebiotic effect in vitro by promoting the growth of Bifidobacterium and increasing SCFA concentrations in the medium. Bajury et al [107] conducted an in vitro colon model in which they evaluated the prebiotic capacity of K. alvarezii. This study showed an increase in SCFA (particularly acetate and propionate) and Bifidobacterium.…”

Potential Use of Marine Seaweeds as Prebiotics: A Review

Human gut microbiota plays an important role in several metabolic processes and human diseases. Various dietary factors, including complex carbohydrates, such as polysaccharides, provide abundant nutrients and substrates for microbial metabolism in the gut, affecting the members and their functionality. Nowadays, the main sources of complex carbohydrates destined for human consumption are terrestrial plants. However, fresh water is an increasingly scarce commodity and world agricultural productivity is in a persistent decline, thus demanding the exploration of other sources of complex carbohydrates. As an interesting option, marine seaweeds show rapid growth and do not require arable land, fresh water or fertilizers. The present review offers an objective perspective of the current knowledge surrounding the impacts of seaweeds and their derived polysaccharides on the human microbiome and the profound need for more in-depth investigations into this topic. Animal experiments and in vitro colonic-simulating trials investigating the effects of seaweed ingestion on human gut microbiota are discussed.

“…Recent studies demonstrate the prebiotic potential of edible seaweed and its components, such as polysaccharides fucoidan and β-glucan, which interact with the human gut microbiota in vitro [14][15][16]. Zhang et al (2018) reported significant structural changes in fecal microbiota of mice fed with Porphyra haitanesisi and Ulwa prolifera, which are edible seaweeds [17].…”

Background: Undaria pinnatifida (wakame) is an edible seaweed. Wakame is a common food in the Japanese diet which exhibits various biological effects. Wakame is rich in dietary fiber. Despite the long history of its intake, changes in the intestinal environment following the ingestion of wakame are unclear.Methods: We examined the effect of a 2-week intake of wakame on defecation frequency and the intestinal microbiota of 22 healthy individuals suffering from low defecation frequency. The clinical trial was designed as an open-label study.Results: Defecation frequency, defined in terms of times per week, days per week, and volume per week significantly increased during the wakame intake period. Furthermore, based on terminal restriction fragment length polymorphism (T-RFLP), the fraction of bifidobacteria as a percentage of all fecal bacteria increased significantly during the wakame intake period. At the phylum, next-generation sequencing (NGS) revealed that the relative abundance of Actinobacteria after wakame intake significantly increased while the abundance of Bacteroidetes decreased. Moreover, species-level analyses revealed that the abundance of Bifidobacterium longum increased significantly after wakame intake. B. longum colony counts on wakame-containing medium were significantly higher than those on medium without wakame.Conclusion: These observations suggest that wakame intake improves intestinal environment and increases the fecal population of bifidobacteria, indicating that it may have prebiotic properties.Keywords: Undaria pinnatifida; wakame; bowel movement; intestinal microbiota; fiber; Bifidobacterium

“…Both hydrocolloids increased the levels of these bacteria in the intestine between 12 and 24 hr after consumption. In another study, Kappaphycus alvarezii algae showed an in vitro bifidogenic effect with a significant increase in Bifidobacterium populations after 24 hr (Bajury, Rawi, Sazali, Abdullah, & Sarbini, ). Song, Mao, Siu, and Wu () reported that lower molecular weight fractions of exopolysaccharide and konjac glucomannan were better used as a carbon source by Bifidobacterium .…”

Extrusion was used as a tool for modifying carrageenan gum. Increased extrusion temperature and shear led to a considerable decrease in dissolution time (DT) (7,200 to 30 s) and faster solubilization (30 to 7 s) when coarse particle sizes (> 212 µm) and hot water were used (p < 0.05). Extrusion process has also altered morphology and white index, in which fines were whiter than larger particles as well as bulk density, crystallinity, and GAB parameters are affected by particle distribution. The apparent viscosity at zero‐shear rate of non‐extruded gum was 0.10 Pa.s whereas values of extruded particles ranged from 0.17 to 0.55 Pa.s, evidencing that larger particle size corresponded to lower viscosity. Even after carrageenan’s polysaccharide molecular disaggregation by extrusion, it maintained high fiber content (minimum 38%). Both extruded and non‐extruded gum stimulated the growth of Bifidobacterium animalis subsp. lactis (Bb 12) in in vitro experiment, suggesting a bifidogenic effect. Practical applications Carrageenan presents poor aqueous dissolution, hindering direct application in liquid foods. Besides, marine‐based ingredients are unexploited sources of bioactive compounds. In this context, thermoplastic extrusion was used as a strategy to reduce its high viscosity, modify the physical properties, and increase the gum use. The results showed that extrusion enhanced dissolution properties and extruded λ‐carrageenan gum presented high dietary fiber content (>38%), suggesting in vitro bifidogenic effect. In terms of industrial applications, extruded carrageenan is promising as a food supplement fiber product.
