Indigestible oligosaccharides (OSs) with specific properties are known to influence overall health status of individuals as well as that of the gastro‐intestinal tract via alteration of the gut microbial composition. These biomolecules selectively stimulate proliferation of desirable bacterial species while inhibiting harmful microbes. Gut microbiota release short chain fatty acids on fermenting these OSs that also promote a healthy gut. Prebiotic activity is resultant of a synergy between the chemical nature of the OSs and the metabolic machinery of beneficial microflora in the human gut. Prebiotic effectiveness of the OSs is also dependent on processing stability during extraction and incorporation into the edible food‐matrix. The present review provides a structural perspective on conventional and potential prebiotic OSs with regards to their effects on colonic microflora, stability and potential application in food systems. Practical applications Altering intestinal microbiota is being viewed as an active mechanism of developing immune resistance, infectious process control and overall health promotion in individuals. Food researchers and segments of the food industry are actively developing products with prebiotic properties looking to maintain health status of the populace and strengthening the competitive market. The insights from this review can drive towards developing food‐incorporated prebiotic formulations from a number of different sources.

Summary The gut microbiota appears critical in the metabolic health and anti‐disease activity. In this review, we discuss three brown seaweed polysaccharides (alginate, laminarin, fucoidan) for their structural information, the digestive behaviour and the effects on gut microbiota. Bioactivities are associated with various physicochemical properties, like solubility, viscosity, hydration properties, molecular weight, monosaccharide composition, and so on. Brown seaweed polysaccharides can be completely utilised by microbes in the large bowel, and they can regulate the gut microbiota. The ultimate metabolite of these polysaccharides is mainly short‐chain fatty acids, which are able to regulate the ecology of the gut microbiota by increasing the growth of beneficial bacteria and inhibiting the growth of some harmful bacteria. In addition, this article also discusses the relationship between the structure and activity of modulating the gut microbiota. Results show that polysaccharides with low molecular weight are more conductive to modulate gut microbiota.

The gut serves as the body's main immunological and digestive system. Furthermore, host immunity is mostly managed there. Nutrients are further broken down and absorbed here. Numerous research investigations have shown evidence that inflammation, oxidative stress, impairment of the intestinal barrier, and imbalance in the gut microbiota can all contribute to a variety of intestinal illnesses and other issues, underscoring the growing significance of intestinal health concerns. Because of their high biological activity and lack of negative side effects, the organic food‐derived chemicals known as brown algal polysaccharides—mainly fucoidan, laminaran, and alginate—have attracted a lot of attention from academics. Because of its many benefits, sodium alginate is one of the biopolymers that has garnered the greatest attention, research, and application. Carotenoids, which are found in our food, have several positive health effects. Their low solubility in water, oxidation susceptibility, chemical instability, accessibility, and restricted solubility in water, however, restrict their use in food and medicine. In this review and in overcoming these constraints, encapsulation might be helpful. Furthermore, the primary goal of our study is to provide a fresh perspective into the control and avoidance of intestinal diseases. It provides more potent alternatives to this system, clarifies the function of alginates in enhancing the encapsulation of carotenoids, and functions as a model for the synthesis of the intestinal protective agent fucoidan.
