Book Synopsis Mechanism of the Novel Antisolvent Vapour Precipitation (AVP) Process by : Jiunn Yuan Tan
Download or read book Mechanism of the Novel Antisolvent Vapour Precipitation (AVP) Process written by Jiunn Yuan Tan and published by . This book was released on 2015 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrafine spherical maltodextrin and maltose particles were successfully produced with the Antisolvent Vapour Precipitation (AVP) technique. Comparison between lactose and maltodextrin reaffirmed that a key requirement for the process is its ability to inhibit crystallization of the material. The precipitation process consists of: (1) an initial phase separation forming an emulsion, (2) phase inversion and (3) finally a water-maltodextrin shrinkage phase which forms the spherical particles driven by interfacial surface tension. Dehydrating the droplet at different stages of the process resulted in different particle morphologies; porous, smooth, microsphere network and microspheres. Higher ethanol relative humidity, higher ethanol absolute humidity and lower initial weight concentration were found to favour the formation of amorphous microspherical particles upon drying. A unique liquid phase separation was observed which leads to the proposed particle formation mechanism for the AVP process. Further quantitative study were conducted using a newly built vapour generation system, incorporating the LabView control and monitoring system and a new humidity measurement technique based on fundamental mass and energy balance. Analysis of the mass change of the droplet throughout the AVP drying process revealed a trend which suggests that the maximum ethanol concentration within the droplet may be the prevailing factor governing microsphere formation. In addition, an interesting observation on the final solid mass recorded for the porous and microsphere network structures showed that these structures exhibit liquid retention behaviour which could be useful for encapsulation applications.In order to better understand the mechanism of the AVP process, additional research was conducted to develop an AVP drying model to describe the simultaneous absorption and evaporation of ethanol and water within the droplet. This model was developed based on fundamental heat and mass transfer analysis and the incorporation of Raoult's Law and UNIFAC model to account for the binary interaction between water and ethanol. Comparison between the model and the experimental measurements revealed overestimation of ethanol absorption and total drying time. Further analysis suggests that this may be attributed to the counter diffusion of water and ethanol during the drying process and possibly non-Fickian diffusion behaviour of ethanol within the droplet. This work provides a fundamental basis for future work on modelling of this physical phenomenon.The mechanism and analysis provided in this work have contributed to a fundamental understanding of the AVP process in forming microspherical particles, which has potential application in drug delivery. Based on the mechanism proposed, the underlying principles of particle formation under AVP drying can be applied to other materials. The formation of porous and microsphere network, with high liquid retention behaviour suggests possible encapsulation application. In addition, the analysis and considerations employed for the AVP drying model provide a fundamental basis for further model development which would be useful in scaling up the AVP process.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this third edition is to consolidate within a single text the most current knowledge, practical methods, and regulatory considerations pertaining to formulations development with poorly water-soluble molecules. A pharmaceutical scientist’s approach toward solubility enhancement of a poorly water-soluble molecule typically includes detailed characterization of the compound’s physiochemical properties, solid-state modifications, advanced formulation design, non-conventional process technologies, advanced analytical characterization, and specialized product performance analysis techniques. The scientist must also be aware of the unique regulatory considerations pertaining to the non-conventional approaches often utilized for poorly water-soluble drugs. One faced with the challenge of developing a drug product from a poorly soluble compound must possess at a minimum a working knowledge of each of the above mentioned facets and detailed knowledge of most. In light of the magnitude of the growing solubility problem to drug development, this is a significant burden especially when considering that knowledge in most of these areas is relatively new and continues to develop.

Book Synopsis Innovative Food Processing Technologies by :
Download or read book Innovative Food Processing Technologies written by and published by Elsevier. This book was released on 2020-08-18 with total page 2482 pages. Available in PDF, EPUB and Kindle. Book excerpt: Food process engineering, a branch of both food science and chemical engineering, has evolved over the years since its inception and still is a rapidly changing discipline. While traditionally the main objective of food process engineering was preservation and stabilization, the focus today has shifted to enhance health aspects, flavour and taste, nutrition, sustainable production, food security and also to ensure more diversity for the increasing demand of consumers. The food industry is becoming increasingly competitive and dynamic, and strives to develop high quality, freshly prepared food products. To achieve this objective, food manufacturers are today presented with a growing array of new technologies that have the potential to improve, or replace, conventional processing technologies, to deliver higher quality and better consumer targeted food products, which meet many, if not all, of the demands of the modern consumer. These new, or innovative, technologies are in various stages of development, including some still at the R&D stage, and others that have been commercialised as alternatives to conventional processing technologies. Food process engineering comprises a series of unit operations traditionally applied in the food industry. One major component of these operations relates to the application of heat, directly or indirectly, to provide foods free from pathogenic microorganisms, but also to enhance or intensify other processes, such as extraction, separation or modification of components. The last three decades have also witnessed the advent and adaptation of several operations, processes, and techniques aimed at producing high quality foods, with minimum alteration of sensory and nutritive properties. Some of these innovative technologies have significantly reduced the thermal component in food processing, offering alternative nonthermal methods. Food Processing Technologies: A Comprehensive Review, Three Volume Set covers the latest advances in innovative and nonthermal processing, such as high pressure, pulsed electric fields, radiofrequency, high intensity pulsed light, ultrasound, irradiation and new hurdle technology. Each section will have an introductory article covering the basic principles and applications of each technology, and in-depth articles covering the currently available equipment (and/or the current state of development), food quality and safety, application to various sectors, food laws and regulations, consumer acceptance, advancements and future scope. It will also contain case studies and examples to illustrate state-of-the-art applications. Each section will serve as an excellent reference to food industry professionals involved in the processing of a wide range of food categories, e.g., meat, seafood, beverage, dairy, eggs, fruits and vegetable products, spices, herbs among others.
