Development and biochemical characterization of freeze-dried guava powder fortified with Lactobacillus plantarum.

Guava (Psidium guajava L.) is one of the most nutrient-dense fruits, which is native to tropical and subtropical regions of the world. The processing of value-added products from guava has not been carried out on a scale similar to some other fruits, which offers an opportunity to fully exploit the potential of this fruit, such as guava-based nutraceutical food products. The objectives of the present study were to develop freeze-dried guava powders (FDGPs) from two guava varieties (white and pink) and characterize their physico-chemical and nutritional properties. FDGP was also incorporated with probiotic strains of Lactobacillus plantarum, to develop a healthy nutraceutical probiotic supplement. Functional groups assessed by Fourier transform infrared (FTIR) spectroscopy exhibited the existence of strong C-Br stretch, O-H stretch, and C=C stretch vibrations; however, scanning electron micrograms (SEMs) showed the flaky structure indicating the presence of starch, dietary fibers, and esterified groups of pectin. Significant mineral concentrations (mg/100g) of potassi-um (323-362), magnesium (26.2-28.8), zinc (0.43-0.51), and iron (0.52-0.63) were observed in FDGPs. The FDGP samples from both guava varieties had high levels of crude fiber (43.94-46.29%), vitamin C (2.27-2.49mg/g), and phenolic compounds (57.50-61.86mgGAE/g) as well as significant antioxidant properties. Fortification of FDGP with L. plantarum strains produced significant results in terms of probiotic viability that was nearly maintained at 108CFU/g up to 60 days in the final product. The viability of probiotics proved that FDGP is a good carrier of prebiotics and can be utilized as a potent probiotic supplement.

Assessment of Ethanolic Extraction of Chlorogenic Acid, Cynarin, and Polyphenols from Burdock (Arctium lappa L.) Roots Under Ultrasound.

The bioactive compounds in burdock (Arctium lappa L.) roots, including chlorogenic acid (CGA) and cynarin, are valuable for use in nutraceutical foods. The ultrasound-assisted extraction of bioactive substances from dried burdock root powder (DBR) was investigated with 95% ethanol to reduce the impact of polysaccharide inulin on the extraction of free CGA and cynarin. The ethanolic extraction of CGA and cynarin was evaluated under ultrasound (300 W) at 40 kHz (U40) and 120 kHz (U120) with shaking at 120 rpm (S120) for comparison. Using a 1/30 (g/mL-solvent) solid-to-liquid ratio at 30 °C in 120 min, amounts of CGA and cynarin with U40 were as high as 818.74 μg/g-DBR and 173.68 μg/g-DBR, respectively, being much higher than those with U120 and S120. Total phenolic content, total flavonoid content, and antioxidant activity of the extract using U40 were significantly better than using U120 and S120. For U40 and U120, CGA increased with a decreasing solid-to-liquid ratio, while cynarin showed a decrease with a decreasing solid-to-liquid ratio using U120. Moreover, no observable degradations of free CGA and cynarin in ethanol were detected. By combining ultrasound and ethanol, the extracts with high-content CGA and cynarin from burdock roots were effectively achieved for use in health foods.

Effects of drying conditions on physical properties, bioactive compounds and antioxidant activity of Andrographis paniculata leaves

Andrographis paniculata (Burm. f.) Wall. ex Nees (AP) is a medicinal plant widely used in the tropical area of Asia. The effects of drying temperature and time on the andrographolide (AG) content, total phenolic content (TPC), 2,2-diphenyl-1- picrylhydrazyl (DPPH) radical scavenging activity and ferric ion reducing antioxidant power (FRAP) activity were investigated. A 3×4 factorial completely randomized design was performed. Sun drying and hot-air drying at different temperatures (50℃, 60℃ and 70℃) and different drying times (5 hrs, 6 hrs and 7 hrs) were investigated. The results demonstrated that a higher drying temperature and a longer time decreased the AG content, the TPC, the DPPH radical scavenging activity and the FRAP activity. Dried AP leaves at 50℃ for 5 hrs had the highest AG content. However, sun drying for 5 hrs resulted in the greatest TPC, DPPH radical scavenging activity and FRAP activity. Therefore, the recommended options for the optimum drying of AP to maintain active ingredients were 50℃ for 5 hrs, while sun drying was recommended to maintain antioxidant activity. These results provided the basis for further development of dried Andrographis paniculata leaf products containing high contents of bioactive and antioxidant activity as functional or nutraceutical foods in the future.

Fast, sensitive, and sustainable colorimetric detection of chlorogenic acid in artichoke waste material

Caffeoylquinic acids (CQAs) are nutraceutical polyphenols highly represented in natural sources, including artichoke waste (AW). In this study a colorimetric method for rapid and sustainable detection of a 5-CQA isomer (Chlorogenic acid) in AW extract was developed by using alkaline Tris buffer (10 mmol L−1, pH 9) to generate a yellow color associated with 5- to 3-CQA isomerization reaction, as suggested by NMR and MS analyses. The strong absorbance at 360 nm was followed by standard UV–Vis methodology. The colorimetric assay was exploited for detection of 5-CQA into leaf extract from artichoke, obtaining a value of 15.2 ± 0.3 μg/mg of dry extract, in agreement with HPLC analysis (14.3 ± 0.7 μg/mg, 106 ± 2 % recovery) used as validation technique, with excellent linear correlation and precision (R2 = 0.9996, avRSD% = 3.2 %). The method is fast and selective, offering a valuable tool for nutraceuticals identification and food waste valorization.

De novo assembly of Idesia polycarpa transcriptome and unsaturated fatty acid biosynthesis candidate genes Mining and functional Identification

Unsaturated fatty acids (UFA) in lipids are the key to nutraceutical oil applications, with various potential applications in nutraceutical functional foods and pharmaceutical industries. In Idesia polycarpa (Salicaceae), more than 80 % of UFA have been found in the fruits; yet, the underlying genetic mechanism remains poorly understood. Due to the lack of theoretical research on the genes related to lipid biosynthesis and the complete genetic transformation system of I. polycarpa fruit, the selection and breeding of I. polycarpa, an excellent oil tree, has been severely restricted. In-depth understanding of the molecular mechanism and gene function of lipid biosynthesis of I. polycarpa fruit is therefore of great significance for the development of I. polycarpa resources. This is not only conducive to the genetic improvement of I. polycarpa by molecular breeding technologies but can also provide a reference for the study of the gene functions of other oil plants. In this study, the FA accumulation patterns of I. polycarpa fruits during 8 growth periods were analysed. Fruit from two developmental periods with different UFA levels were analysed for RNA sequencing by an Illumina NovaSeq 6000 HiSeq platform. De novo transcriptome assembly presented 115,350 unigenes and 4382 differentially expressed genes (DEGs). Functional annotation in the KEGG pathway and combined with DEG data revealed candidate genes potentially involved in UFA biosynthesis. Expression analysis of q-PCR of IpDGAT2, IpGPAT, IpKASII, IpSAD, IpFAD2, IpFAD3 and IpFAD8 suggested that these genes are highly involved in UFA biosynthesis. Full-length candidate genes were cloned and analysed by bioinformatic tools, and function analysis of IpSAD and IpFAD3 showed that these genes regulated the products of linoleic acid metabolism. This study provides a foundation for UFA biosynthesis in Idesia polycarpa, facilitating its genetic breeding in the future.

These agents modulate apoptosis and cellular proliferation, underscoring their potential in preventive strategies. The convergence of nutraceutical and medicine food homology studies highlights a significant shift towards integrating TCM-derived compounds in a preventive health framework. This approach aims not only to enhance efficacy and reduce side effects but also to champion a preventive paradigm using personalized medicine to advance proactive health maintenance and disease prevention. The combination of TCM and western medical practices offers promising avenues for future research and practical applications in GC prevention.

Risk assessment of heavy metals in wild mushroom from Mizoram, India

Heavy metals (HMs) contaminate the environment and pose serious health risks to humans by accumulating in ecosystems, leading to toxicity and various diseases. In Mizoram, HMs pollution is a growing concern, with increasing research on contamination in various environmental sources. Present study aim to evaluate the HMs content in wild mushrooms collected from two different districts in Mizoram, India. Trichaptum biforme and Polyporus philippinensis were collected from Dampa Tiger Reserve (DTR), Mamit and Cantharellus tropicalis and Coprinellus disseminatus were collected from Lalsavunga Park (LP), Aizawl. The collected samples were identified based on standard mycotaxonomical methods and molecular analysis. Four species were evaluated for their cadmium (Cd), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) content and two species were assessed for their health risk associated with consumption of HMs. The ranges of element contents for cadmium (Cd), manganese (Mn), nickel (Ni), lead (Pb) and zinc (Zn) were found to be 0.19 - 0.92, 4.77 - 24, 0.24 - 1.61, 0.23 - 1.84, 9.5 - 30.9 µg/ g dried weight, respectively. The amount of Cd content was found to be over the safety limits values and can cause adverse health effects when consumed regularly. Wild edible mushrooms are valuable nutraceutical foods, but careful collection is essential to avoid health risks from HM contamination.

Insights into diosgenin against inflammatory bowel disease as functional food based on network pharmacology and molecular docking

Inflammatory bowel disease (IBD) is a growing global health problem. IBD is commonly prevalent in Europe and America and the incidence rate in Asia is on the rise due to altered dietary structure. Diosgenin is a natural steroidal saponin derived from Dioscorea plants. Diosgenin is the main active ingredient of some Chinese medicines which are mainly used to treat coronary heart disease, angina and hyperlipidemia. Recently, growing evidence has exhibited a crucial role of diosgenin and dioscin in alleviating IBD in multiple ways. However, the precise mechanism of diosgenin against IBD needs further exploration.In this study, network pharmacological and systematic bioinformatic analyses were performed to investigate the diosgenin's targets against IBD. 71 targets such as SRC, TNF and STAT3 were identified as overlapped genes between diosgenin and IBD. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis exhibited their involvement in the tyrosine kinase signaling pathway and its membrane receptors. Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor resistance and its downstream Ras-MAPK pathway and PI3K-Akt pathway might become the mechanism of diosgenin against IBD. In addition, molecular docking analysis showed that diosgenin has the massive potential of direct binding to tyrosine kinase and its receptors such as SRC, EGFR, FGFR1 and VEGFR. The results above collectively provided evidence that diosgenin is a promising nutraceutical food against IBD.

Assessment of acute, subacute genetic toxicities and immunomodulatory activity of palm (Trachycarpus fortunei) buds

Ethnopharmacology relevancePalm buds are a natural green resource of the forest, which are not only rich in nutrients but contain a large number of phenolic acids and flavonoids, among other components. It has a variety of biological activities such as antioxidant and uterine smooth muscle stimulation.Aim of the study: To evaluate the safety of palm buds for use as a nutraceutical product and food by evaluating the toxicity, subacute toxicity and genotoxicity of the young palm buds. Also studied for its immune-enhancing activity. Materials and methodsAcute toxicity tests were performed in mice using the maximum tolerance method, and the manifestations of toxicity and deaths were recorded after administration of 10,000 mg/mL for 14 consecutive d (days) of observations. To assess subacute toxicity, mice were treated with palm buds (750, 1500, or 3000 mg/mL) daily for 28 days. The teratogenicity of palm buds was assessed by the Ames test, the mouse bone marrow cell micronucleus test, and the mouse spermatozoa malformation test. In addition, we evaluated the immune-enhancing ability of palm buds by the mouse carbon profile test, delayed-type metamorphosis reaction, and serum hemolysin assay. ResultsIn the acute toxicity study, the Median Lethal Dose (LD50) was greater than 10,000 mg/kg bw in both male and female rats. There were also no deaths or serious toxicities in the subacute study. The no-observed-adverse-effect level (NOAEL) was 3000 mg/kg bw. However, the mice's food intake decreased after one week. The medium and high dose groups had a reducing effect on body weight in mice of both sexes. In addition, the changes in organ coefficients of the liver, kidney and stomach in male mice were significantly higher in the high-dose group (3.23 ± 0.35, 0.75 ± 0.05, 0.57 ± 0.05 g) than in the control group (2.94 ± 0.18, 0.58 ± 0.05, 0.50 ± 0.02 g). Hematological analyses showed that all the indices of the rats in each palm sprout dose group were within the normal range. The results of blood biochemical indicators showed that there was a significant reduction in TP in the blood of male mice in the high-dose group (44.6 ± 7.8 g/L) compared to the control group (58.3 ± 15.1 g/L). In histopathological analysis, none of the significant histopathological changes were observed. The results of the immunological experiment in mice showed that the liver coefficient and thymus coefficient of the high-dose group (8400 mg/kg) were significantly lower than the control group. There was no remarkable difference in auricle swelling between each dose palm bud group (1400, 2800, or 8400 mg/kg) and the control group. The anti-volume number of the high-dose group was significantly increased. ConclusionPalm buds have non-toxic effects in vivo and have little effect on non-specific and cellular immunity in the test mice within the dose range of this experiment. The immunoenhancement in mice is mainly achieved through humoral immunity. In conclusion, our results suggest that palm buds are safe for use as healthcare products and food.

Obtaining phenolic-rich extracts from tree nut shells biomass by room temperature green extraction: Molecular insights and attribution analysis

The recycling of tree nut shells biomass (TNSB), a million-tons level inedible food waste, toward food and drug applications should be one of the most promising valorization pathways. However, therein biggest opportunity and challenge is to fully dig for treasure such as its own high-value biomacromolecules and natural active ingredients. This study completed a food and drug grade extraction by using five TNSB sample (i.e., walnut shell, hazelnut shell, macadamia shell, pin nut shell, and pistachio shell), two green solvents (water and ethanol), and cleaner room temperature green extraction (RTGE) technology; and revealed the molecular basis of the raw materials and their extracts through systematic and in-depth molecular analysis. The results showed that TNSB have extremely high lignin content, and their extracts (whether water or ethanol) are rich in phenolic compounds, which results in the latters having extremely strong antioxidant activities (comparable to vitamin C) and α-amylase inhibitory activities (comparable to acarbose). More specifically, walnut shell has the highest ever lignin content of 57% in all reported biomass. The water extract of walnut shell has more excellent properties, such as 147.65 mg/g of total reducing sugars (TRS), 60.49% of total phenolic content (TPC), 0.24 mg/mL of IC50, DPPH, 0.08 mg/mL of IC50, ABTS, and 13.44% of α-amylase inhibitory activity. Further molecular information shows that these reducing sugars are glucose, fructose, arabinose and fucose, and these phenolic compounds include phenol, vanillin, vanillic acid, p-hydroxybenzoic acid, gentisic acid, gallic acid, protocatechuic acid, epicatechin, caffeic acid, and (trans)catechin. These results demonstrate fully that TNSB will become the preferred feedstock species for lignin-first biorefinery in the future, and walnut shell is undoubtedly the best one. Furthermore, TNSB-based RTGE extracts have the potential to be developed into natural antioxidants, preservatives, diabetes-therapeutic pharmaceutical preparations, nutraceutical and functional foods. In addition, we also used XLSTAT software to conduct a systematic attribution analysis, namely, principal component analysis (PCA) and agglomerative hierarchical clustering (AHC), revealing the inner relationship between the multifactors including TRS, TPC, DPPH, ABTS and α-amylase inhibitory activity among TNSB species.

Valorization of Baltic Sea farmed blue mussels: Chemical profiling and prebiotic potential for nutraceutical and functional food development

The severe eutrophication of the Baltic Sea requires mussel (Mytilus spp.) farming to remove nutrients, but farming in a low salinity environment results in smaller mussels that require value enhancement to be economically viable. This study evaluates the biomass valorisation of smaller Baltic mussels, focusing on the extraction of oil, protein and glycogen. It analyses the amino acid profiles, oil and fatty acid contents and glycogen levels of the mussels, as well as their prebiotic properties on beneficial gut bacteria. In addition, the study improves the extraction of bioactive compounds through enzymatic hydrolysis. Results indicate significant seasonal differences, with summer mussels having higher meat and lower ash content, and a rich content of essential fatty acids, particularly omega-3, and amino acids, underscoring the mussels' sustainability as a food source. The enzymatically treated biomass exhibited notable prebiotic activity, proposing health-promoting benefits. The study underscores the valorization of Baltic mussel biomass, highlighting its role in health, nutrition, and environmental sustainability.

Self-assembled α-lactalbumin nanostructures: encapsulation and controlled release of bioactive molecules in gastrointestinal in vitro model.

Implementing encapsulation techniques is pivotal in safeguarding bioactive molecules against environmental conditions for drug delivery systems. Moreover, the food-grade nanocarrier is a delivery system and food ingredient crucial in creating nutraceutical foods. Nano α-lactalbumin has been shown to be a promissory nanocarrier for hydrophobic molecules. Furthermore, the nanoprotein can enhance the tecno-functional properties of food such as foam and emulsion. The present study investigated the nanostructured α-lactalbumin protein (nano α-la) as a delivery and controlled release system for bioactive molecules in a gastric-intestinal in vitro mimic system. The nano α-la was synthesized by a low self-assembly technique, changing the solution ionic strength by NaCl and obtaining nano α-la 191.10 ± 21.33 nm and a spherical shape. The nano α-la showed higher encapsulation efficiency and loading capacity for quercetin than riboflavin, a potential carrier for hydrophobic compounds. Thermal analysis of nano α-la resulted in a ΔH of -1480 J g-1 for denaturation at 57.44 °C. The nanostructure formed by self-assembly modifies the foam volume increment and stability. Also, differences between nano and native proteins in emulsion activity and stability were noticed. The release profile in vitro showed that the nano α-la could not hold the molecules in gastric fluid. The Weibull and Korsmeyer-Peppas model better fits the release profile behavior in the studied fluids. The present study shows the possibility of nano α-la as an alternative to molecule delivery systems and nutraceutical foods' formulation because of the high capacity to encapsulate hydrophobic molecules and the improvement of techno-functional properties. However, the nanocarrier is not perfectly suitable for the sustainable delivery of molecules in the gastrointestinal fluid, demanding improvements in the nanocarrier. © 2024 Society of Chemical Industry.

Effects of Antioxidant Nutraceutical and Functional Foods on Protein Profile of Tuberculosis Patients in Jos Metropolitan, Nigeria

Optimization of concentrations of different n-3PUFAs on antioxidant capacity in mouse hepatocytes

Omega-3 polyunsaturated fatty acids (n-3 PUFAs), mainly including α-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA), possess antioxidant properties and play a crucial role in growth and development. However, the combined effects of ALA, EPA, and DHA at different concentrations have rarely been reported. This work explored the effects of EPA, ALA, and DHA on the viability and antioxidant capacity of mouse hepatocytes, with the objective of enhancing the antioxidant capacity. Within the appropriate concentration range, cell viability and the activity of glutathione S-transferase, superoxide dismutase, and catalase were increased, while the oxidation products of malondialdehyde and the level of intracellular reactive oxygen species were obviously reduced. Thus, oxidative stress was relieved, and cellular antioxidant levels were improved. Finally, response surface optimization was carried out for EPA, ALA, and DHA, and the model was established. The antioxidant capacity of the cells was highest at EPA, ALA, and DHA concentrations of 145.46, 405.05, and 551.52 µM, respectively. These findings lay the foundation for further exploration of the interactive mechanisms of n-3 PUFAs in the body, as well as their applications in nutraceutical food.

Formulation of nanoemulsion parijoto fruit extract (Medinilla Speciosa) with variation of tweens stabilizers.

Nanotechnology has substantial potential for development due to its ability to modify surface characteristics and particle size, facilitating enhanced absorption of functional food compounds and controlled release of active substances to mitigate adverse effects. Nanoemulsion, a stable colloidal system formed by blending oil, emulsifier, and water, was identified as nanotechnology with promising applications. However, investigations into the impact of surfactants on characteristic nanoemulsions need to be more varied. This research gap necessitated further exploration in the advancement of nanotechnology-based foods. The parijoto fruit (Medinilla speciosa), an indigenous plant species in Indonesia, has yet to undergo extensive scrutiny for its potential use as a functional and nutraceutical food. Anthocyanins, a principal compound in the parijoto fruit, had exhibited efficacy in reducing the risk of cardiovascular disease diabetes, demonstrating anti-inflammatory and antioxidant properties. This study aimed to investigate the characteristics of nanoemulsion formulations derived from parijoto fruit extract and to evaluate an optimum condition with various tween surfactants. The findings from this investigation could furnish valuable insights for the further advancement of anthocyanin nanoemulsions from parijoto fruit extract. The results comprised the characterization of nanoemulsion particle size, polydispersity index, ζ-potential, conductivity, pH, and viscosity. Through mathematical modeling and statistical methods, RSM optimizes nanoemulsion by examining the relationships and interactions between independent and response variables. Furthermore, the characterization of nanoemulsion encompassed ζ-potential, polydispersity, particle size, conductivity, pH, and viscosity. Elevated surfactant concentrations resulted in diminished particle sizes and more uniform size distribution, albeit reaching a plateau where surfactant aggregation and micelle formation ensued. Increased concentrations of surfactant type, concentration, and parijoto extract impacted the physical characteristics of nanoparticle size and polydispersity. The optimal process conditions for nanoemulsion consisting of the type of Tween used are Tween 80, Tween concentration of 12%, and parijoto fruit extract concentration of 7.5%, yielding a desirability value of 0.74, categorizing it as moderate.

Antioxidant activity and phenolic content of herbal infusions from medicinal plants used in Argentina

Currently, teas and herbal infusions represent an important part of the human diet. Most contain phenolic compounds with high antioxidant activity, usually associated with human health protective functions. This attribute defines teas and infusions as nutraceutical foods. In Argentina, several native species are traditionally used for medical purposes. Some of those species are Larrea cuneifolia, Larrea nitida, Grindelia chiloensis, Pteromonnina dictyocarpa, Mandevilla laxa, and Monttea aphylla. The objectives of this study were to analyze the antioxidant power and the scavenging capacity of infusions obtained from those six medicinal plants, to characterize the phenolic profile, and to study in vitro their safety or cytotoxicity. Additionally, the potential use of two infusions as antioxidant additives in a food model was evaluated. The results indicated that the analyzed plant species are rich in phenolic acids (e.g., caffeic, ferulic, and chlorogenic acid), and flavonoids (e.g., quercetin and kaempferol), with high antioxidant power. The infusion blend obtained with G. chiloensis and L. cuneifolia exhibited the highest value of antioxidant capacity measured with the FRAP technique (193.4 μg EAA/mg DW). On the other hand, L. cuneifolia infusion showed the greatest antioxidant capacity determined by FRAP (131.9 ± 5.2 μg EAA/mg DW) and DPPH assays (0.453 mL/mg s). Additionally, L. cuneifolia infusion showed the highest phenolic content (232.8 μg GAE/mg DW) and flavonoid content (153.3 μg QE/mg DW). None of the infusions showed toxicity in mammalian cells, except for G. chiloensis. Furthermore, the L. cuneifolia and L. nitida infusions showed a high inhibitory effect on lipid oxidation in ground beef (55% and 51% at 4 days of storage, respectively). The results suggest that the studied infusions are safe and a rich source of antioxidants, which supports their use in traditional medicine. However, further exhaustive studies of G. chiloensis infusion are needed to ensure its safety, as it has shown cytotoxicity. Besides, it is worthwhile to advance the study of L. cuneifolia and L. nitida as sources of dietary antioxidants, due to their high antioxidant power and ability to protect against lipid peroxidation.Graphical

Seaweed as a Safe Nutraceutical Food: How to Increase Human Welfare?

Seaweeds have been utilized for millennia in Asian countries, although they have only more recently become popular in Western society. They began to be used in ancient times because of their long-term properties and, nowadays, seaweeds are being targeted as a potential tool to combat climate change. There are not many laws governing seaweeds because they have just lately been utilized as food. However, guidelines are being developed to regulate their manufacture and use. Because of seaweed’s tendency to accumulate components, whether helpful or poisonous, limited doses of certain substances have been established to prevent consumer overdosage. Aside from chemical safety, microbiological safety is important for people, and preventing any pathogen from spreading and infecting seaweeds is critical. As a result, systems and ways to safeguard consumers must be developed. Because various seaweed species have varied compositions, certain seaweeds may be safer nutraceuticals than others. To ensure the safety of seaweed-based food items, the HACCP (Hazard Analysis Critical Control Point) system needs to be used. The majority of seaweeds consumed come from aquaculture; however, others come from wild harvesting. To ensure the success of the cultures, the waters must be tested for chemicals and biological risks, as well as for the pH, salinity, and temperature. Seaweeds have enormous promise in many industries, but in the food industry, they are beginning to play a major role, and seizing the chances to produce innovative, safe, and sustainable food sources is strongly advised. This critical review investigates the real potential of seaweed as a human food source and as a nutraceutical solution. This review also focuses on the usage of seaweed as a food product and the procedures required to prepare it. In addition, it compiles information on the applicable legislation and regulations, and it addresses the lengthy road that has to be traveled to increase human well-being by employing a new food source in a controlled manner while simultaneously reducing the human population’s health problems.
