Factors affecting the fate of nanoencapsulates post administration.

Nanoencapsulation has found numerous applications in the food and nutraceutical industries. Micro and nanoencapsulated forms of bioactives have proven benefits in terms of stability, release, and performance in the body. However, the encapsulated ingredient is often subjected to a wide range of processing conditions and this is followed by storage, consumption, and transit along the gastrointestinal tract.

Microfluidic assessment of nutritional biomarkers: Concepts, approaches and advances.

Among various approaches to understand the health status of an individual, nutritional biomarkers can provide valuable information, particularly in terms of deficiencies, if any, and their severity. Commonly, the approach revolves around molecular sciences, and the information gained can support prognosis, diagnosis, remediation, and impact assessment of therapies. Microfluidic platforms can offer benefits of low sample and reagent requirements, low cost, high precision, and lower detection limits, with simplicity in handling and the provision for complete automation and integration with information and communication technologies (ICTs).

Development of iron-vitamin multilayer encapsulates using 3 fluid nozzle spray drying.

Considering the growing concern of iron and folic acid deficiency, encapsulation of these nutrients and fortification into foods is emerging as an effective counter-strategy. The present work focuses on a scalable approach for the production of iron, ascorbic acid, and folic acid core-shell encapsulates using novel 3-fluid nozzle (3FN) spray drying with whey protein as core and either pectin or hydroxypropyl methylcellulose (HPMC) as shell polymers. The effect of shell formation was observed by comparing core-shell encapsulates with conventional 2-fluid nozzle (2FN) encapsulates.

Co-electrospun-electrosprayed ethyl cellulose-gelatin nanocomposite pH-sensitive membrane for food quality applications.

Anthocyanin from red cabbage is an important biomolecule suitable for pH sensing due to its oxidoreduction potential that leads to a color change at various pH conditions. The pH-sensitive anthocyanin compound was extracted from red cabbage (1785 ± 235 mg/L) and encapsulated with gelatin as the wall material at the nanoscale (350 nm) through electrospraying. By using a simultaneous electrospraying and spinning process at 20 kV, nanoencapsulated anthocyanin was immobilized on ethyl cellulose (EC) nanofibers and formed as a nanocomposite membrane.

3D printed MCT oleogel as a co-delivery carrier for curcumin and resveratrol.

Designing a suitable matrix to protect sensitive bioactive compounds is an important stage in nutraceutical development. In this study, emulsion templated medium-chain triglycerides (MCT) oleogel was developed as co-delivery carriers for synergistic nutraceuticals, curcumin, and resveratrol and to 3D print in customized shapes for personalized nutrition. To obtain the stable emulsion, gelatin and gellan gum were added such that their protein-polysaccharide interaction helps in the structuring of the oil phase.

Medium chain triglycerides (MCT): State-of-the-art on chemistry, synthesis, health benefits and applications in food industry.

Medium chain triglycerides (MCT) are esters of fatty acids with 6 to 12 carbon atom chains. Naturally, they occur in various sources; their composition and bioactivity are source and extraction process-linked. The molecular size of MCT oil permits unique metabolic pathways and energy production rates, making MCT oil a high-value functional food.

Synergistic potential of nutraceuticals: mechanisms and prospects for futuristic medicine.

Nutraceuticals are valued for their therapeutic effects and numerous health benefits. In recent years, several studies have demonstrated their superior performances when co-delivered; the concept of synergism has been established for various bioactives. Apart from improvements in the bioavailability of partnering compounds, this approach can protect the radical scavenging potential and biological effects of individual compounds.

Micro- and nano-encapsulation of β-carotene in zein protein: size-dependent release and absorption behavior.

β-Carotene is a lipophilic bioactive compound, providing significant health benefits. Formulation of β-carotene-enriched functional foods is a challenge, due to its poor stability, sensitivity towards light, temperature, oxygen, and its poor water solubility which leads to low bioaccessibility and bioavailability. Targeted delivery and controlled release of bioactive compounds directly depend on the encapsulating matrix and particle size.

Cross-linked chitosan microparticles preparation by modified three fluid nozzle spray drying approach.

Owing to chitosan's incredible biocompatibility and biodegradability, bioactive molecules loaded delivery systems based on this polymer have been widely studied for improved health benefits. In the present work, quercetin and ferulic acid encapsulated core-shell structure chitosan microparticles crosslinked with tripolyphosphate and sodium alginate have been fabricated using unique three fluid nozzle (3-FN) spray drying technique. Fluorescent molecules incorporated into the microparticles aided observation of core-shell structure formation.

Surface functionalization of nanobiomaterials for application in stem cell culture, tissue engineering, and regenerative medicine.

Stem cell-based approaches offer great application potential in tissue engineering and regenerative medicine owing to their ability of sensing the microenvironment and respond accordingly (dynamic behavior). Recently, the combination of nanobiomaterials with stem cells has paved a great way for further exploration. Nanobiomaterials with engineered surfaces could mimic the native microenvironment to which the seeded stem cells could adhere and migrate.
