Available in PDF, EPUB and Kindle. Book excerpt: With the overall goal of advancing nano-scale encapsulation technology, two companion problems in the controlled release of small hydrophobic molecules have been studied: equilibrium partitioning and colloidal transport, each within nano-structured matrices. In the first research focus, a solid phase microextraction (SPME) method was developed to measure air-water-surfactant micelle partitioning of hydrophobic analytes. Vapor-liquid partitioning (Kv̳l̳) measurements were performed independently in the headspace (HS-SPME) and via direct immersion in the liquid (DI-SPME), and the results were compared. The method involves varying the total amount of analyte as well as the ratio of vapor to liquid in the closed, static system, such that the need for an external calibration is eliminated. The compounds studied cover four orders of magnitude in Kv̳l̳, and agreement between DI-SPME and HS-SPME results was good, showing that these two methods were capable of providing accurate, complementary measurements. Equilibrium partitioning of limonene to sodium dodecyl sulfate (SDS) micelles was also measured using HS-SPME by varying the concentration of SDS. By fitting the data to a simple model, the cmc was accurately measured and the micelle-liquid partition coefficient was determined. In the second research focus, the diffusion of SDS in solution and in agarose gel was measured and compared with an a priori model for colloidal transport which invokes hydrodynamic and statistical thermodynamic arguments to account for micelle-micelle and micelle-gel fiber interactions. Experimental results show that the concentration effect is enhanced considerably by the strong charge associated with SDS micelles. At high ionic strength, this concentration effect is further enhanced in 1% agarose gel, but in 2% gel the trend reverses, strongly suggesting a decrease in the micellar aggregation number. At low ionic strength, a concentration effect with a pronounced second order dependence is evident. Results show that the diffusion coefficient does not change appreciably with gel concentration up to 2%, and theoretical analysis suggests that this is due to partial canceling between the effects of solute-gel and solute-solute interactions. The pronounced second-order dependence is explained qualitatively by the changing Debye length and its influence on the thermodynamic driving force.

Download or read book Nano and Microencapsulation for Foods written by Hae-Soo Kwak and published by John Wiley & Sons. This book was released on 2014-04-02 with total page 547 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today, nano- and microencapsulation are increasingly being utilized in the pharmaceutical, textile, agricultural and food industries. Microencapsulation is a process in which tiny particles or droplets of a food are surrounded by a coating to give small capsules. These capsules can be imagined as tiny uniform spheres, in which the particles at the core are protected from outside elements by the protective coating. For example, vitamins can be encapsulated to protect them from the deterioration they would undergo if they were exposed to oxygen. This book highlights the principles, applications, toxicity and regulation of nano- and microencapsulated foods. Section I describes the theories and concepts of nano- and microencapsulation for foods adapted from pharmaceutical areas, rationales and new strategies of encapsulation, and protection and controlled release of food ingredients. Section II looks closely at the nano- and microencapsulation of food ingredients, such as vitamins, minerals, phytochemical, lipid, probiotics and flavors. This section provides a variety of references for functional food ingredients with various technologies of nano particles and microencapsulation. This section will be helpful to food processors and will deal with food ingredients for making newly developed functional food products. Section III covers the application of encapsulated ingredients to various foods, such as milk and dairy products, beverages, bakery and confectionery products, and related food packaging materials. Section IV touches on other related issues in nano- and microencapsulation, such as bioavailability, bioactivity, potential toxicity and regulation.
