Abstract

Macro- and microalgae-based foods are becoming popular due to their high nutritious value. The algal biomass is enriched with polysaccharides, protein, polyunsaturated fatty acids, carotenoids, vitamins and minerals. However, the most promising fraction is polysaccharides (PS) or their derivatives (as dietary fibers) which are not entirely fermented by colonic bacteria hence act as potential prebiotic. Primarily, algae become famous as prominent protein sources. Recently, these are widely adopted as functional food (e.g., desserts, dairy products, oil-derivatives, pastas etc.) or animal feed (for poultry, cattle, fish etc.). Besides prebiotic and balanced amino acids source, algae derived compounds implied as therapeutics due to comprising bioactive properties to elicit immunomodulatory, antioxidative, anticancerous, anticoagulant, hepato-protective, and antihypertensive responses. Despite the above potentials, broader research determinations are inevitable to explore these algal compounds until microalgae become a business reality for broader and specific applications in all health domains. However, scale up of algal bioprocess remains a major challenge until commercial affordability is accomplished which can be possible by discovering their hidden potentials and increasing their value and application prospects. This review provides an overview of the significance of algae consumption for several health benefits in humans and animals mainly as prebiotics, however their functional food and animal feed potential are briefly covered. Moreover, their potential to develop an algal-based food industry to meet the people's requirements not only as a sustainable food solution with several health benefits but also as therapeutics is inevitable.

  • Microalgal polysaccharides selectively promote growth of beneficial gut microbes such as Lactobacillus, Bifidobacterium, and Faecalibacterium prausnitzii.

    “These compounds have been shown to selectively promote the growth of beneficial gut microbes such as Lactobacillus, Bifidobacterium, and Faecalibacterium prausnitzii, as supported by recent studies on microalgae-derived prebiotics [60,61].”

    From Microalgae Bioactives for Functional Food Innovation and Health Promotion (2025) · cites this paper as [61]

    The Background and Table 4 (pages not provided) report that algal extracts or oligo-/polysaccharides promote Lactobacillus and Bifidobacterium. Table 4 lists Faecalibacterium prausnitzii as increased by fructans, not by microalgal polysaccharides, so the claim's attribution for that species is unsupported. (LLM, conf=0.88)

  • Microalgae contain non-digestible polysaccharides and fibres with prebiotic effects, including sulphated polysaccharides, β-glucans, and xylans/rhamnose-rich polysaccharides.

    “Microalgae contain various non-digestible polysaccharides and fibres with prebiotic effects, including sulphated polysaccharides (e.g., from Porphyridium), β-glucans (e.g., from Chlorella), and xylans and rhamnose-rich polysaccharides (e.g., from Spirulina).”

    From Microalgae Bioactives for Functional Food Innovation and Health Promotion (2025) · cites this paper as [61]

    The ‘Prebiotic potential of algal compounds’ section says algal polysaccharides are generally undigested in the upper gut and can act as prebiotics; it also identifies β-glucan in C. vulgaris. It does not identify sulphated polysaccharides in Porphyridium or xylans and rhamnose-rich polysaccharides in Spirulina, although Table 4 lists prebiotic effects for oligo- and polysaccharides in Spirulina biomass. No page numbers are available in our copy. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
