These consist of chitin, β-D-glucans, and β-glucan polymers. Mushroom wastes can yield cereal β-glucans, which are thought to have immune modulatory properties [1]. Because of their great nutritional value, non-cellulosic β-glucans are added to cereal foods such as whole grains, wheat, bran, oats, etc. These stimulate the immune system of the body, most likely as a result of increased microbial activity in the intestine [2]. Mushroom wastes have a high content of edible nutrients, as demonstrated by in vitro tests and prebiotic efficacy in pre-clinical testing. Experiments revealed that nutrients taken out of mushrooms could eventually be a major source of high-quality prebiotics. As part of the process of figuring out how nutrients function, it was discovered that, in comparison to other probiotic varieties, bifido bacteria are more sensitive to changes in pH, oxygen stress, and temperature. Thus, the nutrients regulated the amount of oxygen that entered the probiotics. This gave the bifido bacteria a safe haven, and as a result, their metabolic activity was observed to rise. Thus, the findings suggest that when utilized as prebiotics, nutrients derived from low-cost mushroom wastes can have a significant impact (Boluduc and others, 2006). When applied to different fruits for preservation purposes, poly-anionic pectin and poly-cationic chitosan have been shown in numerous trials to exhibit protective effect. Both kept the fruit preserved fresher for longer by stopping water and oxygen from evaporating from their skin. (Alvarez and others, 2012). Several experimental studies have demonstrated the use of edible coatings based on polysaccharides, with chitosan on the outermost layer, on citrus fruits to preserve the fruit's outer skin, extend its shelf life, and enhance the aesthetic appeal of different citrus fruit varieties. The goal of these investigations is to create edible coatings based on polysaccharides that can be applied to citrus fruits' outer peel in place of artificial waxes [3,4]. The main ingredients used to make the edible films or coatings that are applied on the outside of fruits are poly-cationic chitosan and poly-anionic pectin. According to scientific research, the layers of edible film shield the fruit's exterior layer from drying out and inhibit the formation of fungi. This suggests that the antibacterial properties of chitosan and the poor oxygen permeability of pectin work together to help prolong the shelf life of fruits when they are used in combination. (Alvarez and others, 2012). Applying a nano-multilayer edible coating made of poly-anionic alginate and poly-cationic chitosan on newly cut mangoes extends their shelf life by up to eight days, according to another experimental study [5].

Applications of Nutrients in the Field of Medicine

The nutrition class that has been examined the most is sulfated nutrients. One type of sulfated nutrient found in seaweeds, particularly green and brown algae, is fucoidan [6,7]. Fucose, a fundamental deoxy sugar group with the molecular formula C6H12O5, is present in these, which are primarily collected from the cell walls of brown algae and other seaweeds. Due to their many therapeutic properties, fucoidans are widely used in the medical and pharmaceutical industries. According to recent studies, many fucoidans have been identified and their biological activities have been revealed over the last few decades. (Li and others, 2008). Since fucoidans are found in the cell wall matrix of seaweeds, extracting biologically active nutrients from them using water as a solvent is a challenging process. Therefore, enzyme-assisted extraction procedures are employed [8]. An internal or external stimulation triggers a series of events inside the body that result in inflammation, often known as an inflammatory process. Anti-inflammatory drugs are intended to lessen the body's response to that specific occurrence, or inflammation. In 2010 [9] Fucoidan, derived from Eklonia cava, a brown algae that is found in the oceans of Korea and Japan, has been shown in a recent experimental study to be a potent anti-inflammatory agent. This is because it effectively blocks the expression of the COX-2 gene and inhibits the lipopolysaccharide-dependent iNOS (inducible nitric oxide synthase) activity. Furthermore, fucoidan prevents lipopolysaccharide in RAW 264.7 from producing nitric oxide and PGE2 (Prostaglandin E2), which in turn reduces inflammation [10,11]. Increased inflammatory cytokine production and a steady supply of inflammatory cells cause the destruction of connective tissues in chronic inflammatory diseases including rheumatoid arthritis and chronic wounds. Ascophyllum nodosum fucoidan has been shown to be a powerful regulator of the proteolysis of aggravated connective tissues. Fucoidan can be utilized to treat certain inflammatory conditions where extracellular matrix degrades uncontrolled, according to other studies [12]. We now know about the isolation and purification of naturally occurring nutrients that are sulfated and function as strong anticoagulants in contrast to heparin and other anticoagulant medications, thanks to the growing interest and advancement in the field of research and drug use following preclinical trials [13]. The anticoagulant activity of fucoidan, which was isolated from the brown alga Eklonia cava, was analyzed in a recent experimental report. Prothrombin, partial thromboplastin, and thrombin times were all measured. It was shown that the anticoagulant properties of heparin and fucoidan were comparable [14]. Fucoidans derived from Eklonia cava have been shown in an in vivo investigation to enhance the activity of AT-III (Anti-Thrombin III) mediated coagulation factor inhibition, contributing to the notable anti-coagulant properties of sulfated fucoidans [15]. Simple fermentation and chromatographic methods can be used to isolate and purify sulfated nutrients with fucose deoxy sugar group from Sargassum fulvellum, a brown seaweed, for use as an anti-coagulant agent. This is because fermentation may enhance the bioactive potentials of fucoidans [13]. Recent developments in research methods have shown a wide range of fucose types that contain fucoidans, sulfated nutrients derived from different kinds of seaweeds and algae species that have anti-tumor or anti-cancer properties. Fucoidans from the edible seaweed species Undaria pinnatifida have been the subject of numerous experimental investigations over the past few decades. These studies have demonstrated that the fucoidans have anti-proliferative or anti-cancer activity in PC-3 (prostate cancer cells), A549 (adenocarcinoma epithelial cells), HeLa (cervical cancer cells), and Hep G2 (liver cancer cells) [16]. Fucoidan isolated from Eklonia cava is observed to cause apoptosis in HS-Sultan cells, a cell line subcloned from Burkitt lymphoma. According to other findings, caspase-3, a mediator of apoptosis, is activated in conjunction with fucoidan's apoptotic action [17]. Experimental investigation conducted in vitro on fucoidans extracted from Laminaria guryanovae on inhibition of EGFR (epidermal growth factor receptor) activation [10]. The results showed a strong inhibitory effect on the phosphorylation of the epidermal growth factor receptor that is triggered by EGF. This receptor is a key target in the therapy of cancer because it regulates cell proliferation, differentiation, and transformation [18,19]. Spirulina platensis or Arthrospira platensis Often referred to as spirulina, this multicellular, filamentous blue-green algae is regarded as an amazing source of nourishment [20]. Spirulina's primary polymeric constituent is a branching polysaccharide with a structure resembling glycogen. High molecular weight nutrients with antiviral and anticancer properties are identified [21]. It has been discovered that macrophages produce more TNF-α (tumor necrosis factor-alpha) when exposed to acidic nutrients that are extracted from spirulina [22]. Additionally, sulfated nutrients found in spirulina exhibit antiviral activity by preventing the growth of the human immunodeficiency virus (HIV), measles, mumps, influenza A virus, herpes simplex, and cytomegalovirus (CMV) [23]. According to an experimental investigation, calcium spirulan, a sulfated polysaccharide found in spirulina, efficiently blocks the adsorption and penetration of viruses into cells, hence reducing viral multiplication by 50%. Nutrients extracted from spirulina microalgae have been shown in certain experimental investigations to have anti-cancer effects on a variety of cancer cell lines. With the help of these nutrients, carcinoma can be prevented or treated at various stages of development—even before symptoms appear [24]. An in vivo investigation conducted on rats revealed that spirulina extract suppresses buccal mucosa tumors. Endonuclease enzyme activity causes DNA damage, which is repaired to make this possible. Certain minerals included in the spirulina extract serve to stimulate the enzyme endonuclease, which repairs damaged DNA [25].
