Nutrition—nutrient delivery

Comparative study of the structural and physicochemical properties of two food derived antihypertensive tri-peptides, Isoleucine-Proline-Proline and Leucine-Lysine-Proline encapsulated into a chitosan based nanoparticle system

“…Chitosan is positively charged under acidic conditions, to an extent which depends on the degree of deacetylation (DD), the percentage of primary amino groups in the polymer backbone and molecular weight. An increase in DD allows the ionisation of the chitosan, which increases the viscosity, resulting in an extended conformation with more charge repulsion and a more flexible chain (Kumirska et al, 2010;Vozza, Khalid, Byrne, Ryan, & Frias, 2016). For encapsulation purposes, chitosan at high DD is usually selected to allow more possibilities for the bioactive to interact (i.e.…”

“…increasing molecular mobility) (Szymańska & Winnicka, 2015). Nanoparticle based drug delivery systems have been widely used in the area of encapsulation, using different carrier systems (Vozza et al, 2016). Studies have shown the potential of controlling NP size and surface properties and the resultant formulations have provided site-specific action of the drug at the optimal therapeutic rate and dose (Yun, Cho, & Park, 2013a).…”

Zein Beta-Cyclodextrin Micropowders for Iron Bisglycinate Delivery

“…An amount of micropowder (100 mg) was treated with water (4 mL) to solubilise free βCD. After centrifugation (5400× g for 30 min), the supernatant was collected and either treated with phenolphthalein (1) or freeze-dried and weighted (2).…”

“…A significant trend in the modern food industry is the development of food supplements specifically designed to improve human health and well-being, reduce the incidence of certain diseases, and improve human performance. In this context, the design, fabrication, and characterisation of polymer-based delivery platforms able to protect and to deliver the bioactive components in the body are in the limelight at the moment [1,2]. Among natural polymers, zein is a corn protein that has been widely employed at an industrial level due to several advantages.…”

Nanoagriculture: A Holistic Approach for Sustainable Development of Agriculture

“…Nanotechnology has broader applications in the food industry; the fabrication of nanoparticles like micelles, liposomes, nanoemulsions, and biopolymeric nanoparticles; and the manufacturing of nanosensors which intends food security. Nanotechnology has evolved some of the bioactive compounds like omega-3 and omega-6 fatty acids, probiotics, prebiotics, vitamins, and minerals and their implementation in nanofoods [36].…”
