“…This demonstrated that the higher stability of the emulsions generated by GP-GED-TA as compared with GED-TA was not caused by the viscosity difference of the emulsions. The emulsions formed by GED-TA or GP-GED-TA exhibited the shear thinning behavior at shear rates of 1 to 1000 (1/s), suggesting formation of a weak network structure in emulsion stabilized by the GED-TA or GP-GED-TA [8].

“…Conventionally, O/W emulsions are prepared and stabilized by surfactants, but recent reports have focused on O/W Pickering emulsions, which are stabilized by nanoparticles [4][5][6]. Particles effectively inhibit the flocculation or coalescence of oil droplets in emulsions, by surrounding the oil droplets and keeping them apart [7,8]. In addition, the adsorption energy of a particle at the oil-water interface is much higher than its thermal energy.…”

The aim of this study was to fabricate edible gelatin enzymic digest (GED) based gel particles that can stabilize oil-in-water (O/W) microemulsions. The gel particles were generated by covalent crosslinking, with genipin, the individual protein molecules within tannic acid-induced gelatin hydrolysate (GED-TA) particles. The ability of the genipin-treated GED-TA (GP-GED-TA) to stabilize emulsions was evaluated by Turbiscan analysis and droplet-size changes. For comparison, gelatin hydrolysate (GE) and tannic acid-induced gelatin hydrolysate particles (GED-TA) were used as controls. The mean diameters of GED, GED-TA, and GP-GED-TA particles were 0.68 ± 0.1 nm, 66.2 ± 8.4 nm, and 66.9 ± 7.2 nm, respectively. Nanomechanic analysis using atomic force microscopy(AFM) indicated the average Young’s modulu of the GP-GED-TA particles was 760.8 ± 112.0 Mpa, indicating the GP-GED-TA were soft particles. The Turbiscan stability indexes (lower values indicate a more stable emulsion) of the emulsions stabilized with GED, GED-TA, and GP-GED-TA, after storage for three days, were 28.6 ± 1.5, 19.3 ± 4.8, and 4.4 ± 1.3, respectively. After one, or 60 days of storage, the volume-weighted mean diameters (D[4,3]) of oil droplets stabilized by GP-GED-TA were 1.19 ± 0.11 μm and 1.18 ± 0.1 µm, respectively. The D[4,3] of oil droplets stabilized by GED-TA, however, increased from 108.3 ± 5.1 μm to 164.3 ± 19.1 μm during the storage. Overall, the GP-GED-TA gel particles have considerable potential for stabilization of O/W emulsions in food products.

complex drug delivery systems that are challenging to scale up and therefore have limited clinical and commercial translation. Although numerous nanoparticles have been widely developed and used for various applications, including biomedical applications, [2] there is a growing interest in nontoxic and degradable alternatives to first-generation synthetic nanomaterials. Ideally the synthesis of such nanoparticles needs to be cost effective, simple, green, reproducible, scalable, and the constitutive building blocks of the nanoparticles should be nontoxic, functional, biodegradable, and available on a large scale. Naturally occurring nanoparticles could be such a valid alternative. These nanoparticles include intracellular structures, such as magnetosomes [3] and glycogen, and extracellular assemblies such as lipoproteins and viruses. [3] Among these, glycogen is the most abundant and versatile biological nanoparticle, which fulfils the requirements for the fabrication of nanostructured biomaterials. Glycogen is nature's prime nanoparticle that exists in most organisms, from bacteria and archaea to humans, [4,5] as a vital component of the cellular energy machinery. It is a highly branched polysaccharide comprising repeating units of glucose connected by linear α-d-(1,4) glycosidic linkages with α-d-(1,6) branching, structured into roughly spherical nanoparticles that have a high water solubility and molecular weight.The use of polysaccharides as components for advanced materials has been an attractive concept for decades. [6,7] A key motive is that polysaccharides, as a natural biomaterial, are endowed with a level of biodegradability and biocompatibility. In addition, they can be easily modified chemically or biochemically to produce functional derivatives, which are important for various therapeutic applications. [8] The structures of polysaccharides vary considerably but span from linear to highly branched polymers with molecular weights ranging from thousands to millions, composed of mono-or disaccharides, or short-chain oligomers bound together by glycosidic linkages. [9] There is a rich history of research on the use of polysaccharides in a range of therapeutic applications including: i) soft tissue engineering, [10,11] where the materials can be designed to mimic the mechanical properties of the extracellular matrix in the tissue; ii) as drug, protein, or gene delivery systems, [7,12,13] where polysaccharides have a large number of reactive groups [14] that allow for tunable properties [12] such as pH-responsiveness; [15] and iii) as nanoprobes for cellular Biological nanoparticles found in living systems possess distinct molecular architectures and diverse functions. Glycogen is a unique biological polysaccharide nanoparticle fabricated by nature through a bottom-up approach. The biocatalytic synthesis of glycogen has evolved over time to form a nanometer-sized dendrimer-like structure (20-150 nm) with a highly branched surface and a dense core. This makes glycogen markedly different from other natur...

“…With a properly designed food‐grade delivery system, the bioactive component can be made more bioavailable and stable so that it can be incorporated into pharmaceuticals and functional foods. Modified starches have received attention in encapsulating various types of nutraceuticals and making them available in a controlled‐release manner (Lu et al., ; Ye et al., , , ). As noted above, large‐ring cycloamyloses have hydrophilic external surfaces and relatively hydrophobic cavities giving them the ability to form water‐soluble complexes with various poorly soluble bioactives, including carotenoids, phenolic compounds, and flavonoids (Taira, Nagase, Endo, & Ueda, ; Ueda, ).…”

Starch is an abundant, natural, renewable resource, and present as the major storage carbohydrate in the seeds, roots, or tubers of many important food crops, such as maize, wheat, rice, potato, and cassava. Uses of native starches in most industrial applications are limited by their inherent properties. Hence, they are often structurally modified after isolation to enhance desirable attributes, to minimize undesirable attributes, or to create new attributes. Enzymatic, rather than chemical, approaches are used in the production of starch syrups, maltodextrins, and cyclodextrins. However, the desire for starch-active enzymes working optimally at high temperatures and low pH conditions with superior stability and activity is still not satisfied and this stimulates interest in developing novel and improved starch-active enzymes through a variety of strategies. This review provides current information on enzymes belonging to GH13, 57, 70, and 77 that can be used in structural modifications of the starch polysaccharides or to produce starch-derived products from them. The characteristics and catalytic mechanisms of microbial enzymes are discussed (including 4-α-glucanotransferase, branching enzyme, maltogenic amylase, cyclomaltodextrinase, amylosucrase, and glucansucrase). Product diversity after starch-converting reaction and utilization in industrial applications are also dealt with.
