Nanoemulsions by Seid Mahdi Jafari


Original Title: Nanoemulsions

Nanoemulsions: Formulation, Applications, and Characterization provides detailed information on the production, application and characterization of food nanoemulsion as presented by experts who share a wealth of experience. Those involved in the nutraceutical, pharmaceutical and cosmetic industries will find this a useful reference as it addresses findings related to different preparation and formulation methods of nanoemulsions and their application in different fields and products. As the last decade has seen a major shift from conventional emulsification processes towards nanoemulsions that both increase the efficiency and stability of emulsions and improve targeted drug and nutraceutical delivery, this book is a timely resource. Summarizes general aspects of food nanoemulsions and their formulation Provides detailed information on the production, application, and characterization of food nanoemulsion Reveals the potential of nanoemulsions, as well as their novel applications in functional foods, nutraceutical products, delivery systems, and cosmetic formulations Explains preparation of nanoemulsions by both low- and high-energy methods

Stable Nanoemulsions by Joseph S. D'Arrigo


Original Title: Stable Nanoemulsions

Certain stable lipid nanoemulsions, existing in natural waters and certain artificial media, display - upon intravenous injection - a marked capability for rapid active targeting, both to tumors and to certain lesion sites. This category of lipid nanoemulsions contains no phospholipids, no proteins nor peptides, no carbohydrates, and no chemical modification of the lipophilic drugs is required; consequently it avoids various past problems reported for earlier versions of targeted nanoemulsions. The book covers in detail the underlying chemical and biochemical principles of stable lipid nanoemulsions as well as many current and potential applications in nanomedicine such as targeted chemotherapy. It is in harmony with goals of the current US National Nanotechnology Initiative, which include nanomedical approaches to drug delivery that focus on developing nanoscale particles to improve drug bioavailability i.e. often using targeted nanoparticles for delivering drugs with cell precision and less side effects. Despite the obvious practical importance to various fields including nanomedicine there is currently no comprehensive book available in the literature. The proposed book will effectively fill this gap. Detailed coverage of the underlying chemical and biochemical principles of stable lipid nanoemulsions. The book includes many current and potential applications in nanomedicine such as targeted chemotherapy. Contains 67 figures (including 13 microscope photos) and 26 tables Over 1200 literature references, many of them of very recent date.

Techniques For Nanoencapsulation Of Food Ingredients by C. Anandharamakrishnan


Original Title: Techniques For Nanoencapsulation Of Food Ingredients

Nanoencapsulation has the potential to improve human health through its capacity to both protect bioactive compounds and release them at a specific time and location into various substances, including food. Numerous nanoencapsulation technologies have emerged in recent years, each with its own advantages and disadvantages. The goal of this Brief is to discuss the various nanoencapsulation technologies, such as emulsification, coacervation, inclusion encapsulation, anti-solvent precipitation, nanoprecipitation, freeze drying, and spray drying, including their limitations. Recent safety and regulatory issues concerning the various nanoencapsulation technologies will also be covered.

Improving The Stability Of Beta Carotene And Citral By Nanoemulsions by Xiaoqing Yang


Original Title: Improving The Stability Of Beta Carotene And Citral By Nanoemulsions

In this study, various nanoemulsion formulations were prepared to encapsulate non-polar beta-carotene and partly polar flavor molecule citral. For the encapsulation of beta-carotene, the nanoemulsion core material was a mixture of both solid lipid (palm kernel fat) and liquid oil (medium chain triglyceride, MCT). Aqueous nanoemulsion dispersions were obtained by the combination of high speed and high pressure homogenization processes and the solid nanoemulsion powders were also obtained by lyophilization using sucrose as the cryoprotectant. For the aqueous dispersions, the formulation using pure palm kernel fat as the lipid phase was the best one to protect beta-carotene from degradation. For the freeze-dried samples, the incorporation of liquid MCT oil is necessary to disturb solid lipid crystallization to protect beta-carotene. The in vitro digestion experiments were performed to evaluate the bioaccessibility of beta-carotene in palm kernel fat nanoemulsion and MCT nanoemulsion; the results showed that the bioaccessibility of beta-carotene was greatly improved after encapsulation. The palm kernel fat had better performance than the MCT to release beta-carotene from the nanoemulsion formulations. For the encapsulation of citral, two strategies were developed to improve citral stability at acidic condition (pH = 3.0). The first strategy was to incorporate six different natural antioxidants (black tea extract, ascorbic acid, naringenin, tangeretin, beta-carotene and tanshinone) with citral together in the palm kernel fat nanoemulsions. The second strategy was to construct multilayer nanoemulsions to encapsulate citral. The multilayer emulsions were prepared by the layer-by-layer deposition technique between oppositely charged emulsion droplets and two polymer coatings: chitosan (CS) and Îæ-polylysine (EPL). The stability of citral as well as the production of the off-flavor compounds was analyzed by solid phase microextraction gas chromatography (SPME-GC). The results suggested that encapsulation of citral in combine with the appropriate antioxidants (beta-carotene, tanshinone and black tea extract) could greatly enhance citral's chemical stability during storage; and the additional cationic chitosan interfacial layer was also effective to improve the stability of citral.
