“…Alginate is mainly extracted (20-40%content of the dry weight) from the cell walls of brown marine seaweed (Phaeophyceae) such as Ascophyllum nodosum, Laminaria species, Fucus species, Macrocystis pyrifera and Ecklonia species [213][214][215] and in low amount extracted from bacterial origin as exopolysaccharides such in the case of Azetobacter and Pseudomonas species [213]. Chemically, alginates are made up of (1→4)-linked α-l-guluronic acid (G) and β-d-mannuronic acid (M).…”

The use of polysaccharide-based materials presents an eco-friendly technological solution, by reducing dependence on fossil resources while reducing a product's carbon footprint, when compared to conventional plastic packaging materials. This review discusses the potential of polysaccharides as a raw material to produce multifunctional materials for food packaging applications. The covered areas include the recent innovations and properties of the polysaccharide-based materials. Emphasis is given to hemicelluloses, marine polysaccharides, and bacterial exopolysaccharides and their potential application in the latest trends of food packaging materials, including edible coatings, intelligent films, and thermo-insulated aerogel packaging.

“…For that purpose, the application of various pre-treatment solvents at different temperatures has been studied. A mixture of methanol, chloroform and water at 4:2:1 (v/v/v) has been successfully used for defatting, and acetone [14] as well as mixture of acetone and ethanol [15] or methanol [16] were used to remove lipids and pigments. The second type of pre-treatments which is carried out in order to disrupt cell wall material and enhance the mass transfer of the target compounds to the extraction solvent result in an improved extraction yield [13].…”

Over the years, brown algae bioactive polysaccharides laminarin, alginate and fucoidan have been isolated and used in functional foods, cosmeceutical and pharmaceutical industries. The extraction process of these polysaccharides includes several complex and time-consuming steps and the correct adjustment of extraction parameters (e.g., time, temperature, power, pressure, solvent and sample to solvent ratio) greatly influences the yield, physical, chemical and biochemical properties as well as their biological activities. This review includes the most recent conventional procedures for brown algae polysaccharides extraction along with advanced extraction techniques (microwave-assisted extraction, ultrasound assisted extraction, pressurized liquid extraction and enzymes assisted extraction) which can effectively improve extraction process. The influence of these extraction techniques and their individual parameters on yield, chemical structure and biological activities from the most current literature is discussed, along with their potential for commercial applications as bioactive compounds and drug delivery systems.(APS) is determined by algae species however it is also influenced by other factors causing inter-species variation, e.g., growth location and harvesting season [8]. Vast structural variation between the APS therefore presents a challenge in terms of pre-treatments application, extraction techniques and optimization, characterization of isolated fractions and determination of their biological properties.Chemical structure and yield of APS isolated from marine macroalgae by conventional extraction (CE) techniques can be affected by various experimental conditions (pH, time, temperature, pressure, particle size, solvent, sample to solvent ratio, agitation speed etc.). In addition, different advanced techniques such as microwave assisted extraction (MAE), ultrasound assisted extraction (UAE), pressurized liquid extraction (PLE), enzyme-assisted extractions (EAE) are assessed and applied for APS extraction [9][10][11].In general, the chemical structure of polysaccharides determines its physical, chemical and biochemical properties as well as its biological activities [12]. Several studies have reported that their biological activity is strongly associated with their chemical structure [9]. Due to very complex mechanisms that are affected by many factors, the correlation between polysaccharide structure and biological activity is still not sufficiently clarified.In order to improve isolation of APS, pre-treatments are usually applied to the algal biomass prior to the extraction process with the two aims: (i) to prevent co-extraction of interfering bioactive compounds with similar solubility; and (ii) to disrupt cell walls and improve mass transfer of APS into extraction solvent. The first type of pre-treatments is therefore used to remove compounds which are highly bound to the APS such as proteins, phenols and lipids, as well as mannitol and chlorophyll [13]. For that purpose, the application of various pr...

Water‐soluble polysaccharides (WSP) were secluded from Tamarindus indica (TWSP) and Pithecellobium dulce (PWSP) seeds by hot water method. The physico‐chemical properties revealed that the polysaccharides might be used as a potential food additive. The micrometric properties of TWSP and PWSP possessed a bulk density of 0.64 and 0.68 g/ml, respectively. The isolated polysaccharides were subjected to Fourier transform infrared spectroscopy and Nuclear magnetic resonance spectroscopy for its compositional analysis and exhibited that both the isolates are heteropolysaccharides. The spectra of both the mucilages were resonating at δ 3.00–δ 5.00 ppm which confirmed the presence of polysaccharides. Thermo gravimetric analysis showed that the isolated polysaccharides were thermally stable. Scanning electron microscopy and X‐ray diffraction depicted the morphological characteristics. The radical scavenging ability and antibacterial activity proved that the polysaccharides can be explored as a functional food ingredient. Furthermore, the prebiotic potential of polysaccharides stimulated the growth of Lactobacillus delbrueckii and Lactobacillus fermentum over inulin. Practical applications The study provides optimum extraction conditions to obtain TWSP and PWSP seeds using response surface methodology. The isolated polysaccharides can be used as therapeutic agent and as a food additive due to its high purity obtained from Fourier transform infrared spectroscopy and Nuclear magnetic resonance spectroscopic analysis. The excellent flowability and compressibility of polysaccharides can be applied in pharmaceutical formulation as an excipient. The active component present in the isolated polysaccharides can be used as a food preservative. The supplement of TWSP and PWSP as a carbon source accelerated the growth of probiotics which could be used as natural prebiotics. Thus the study concluded that the water‐soluble polysaccharide obtained from the agro‐industrial by product has the wide application in food and pharmaceutical industries.
