The encapsulation process has been utilized in the field of food technology to enhance the technofunctional properties of food products and the delivery of nutraceutical ingredients via food into the human body. The latter application is very similar to drug delivery systems. The inherent sophisticated nature of release mechanisms requires the utilization of mathematical equations and statistics to predict the release behavior during the time. The science of mathematical modeling of controlled release has gained a tremendous advancement in drug delivery in recent years. Many of these modeling methods could be transferred to food. In order to develop and design enhanced food controlled/targeted bioactive release systems, understanding of the underlying physiological and chemical processes, mechanisms, and principles of release and applying the knowledge gained in the pharmaceutical field to food products is a big challenge. Ideally, by using an appropriate mathematical model, the formulation parameters could be predicted to achieve a specific release behavior. So, designing new products could be optimized. Many papers are dealing with encapsulation approaches and evaluation of the impact of process and the utilized system on release characteristics of encapsulated food bioactives, but still, there is no deep insight into the mathematical release modeling of encapsulated food materials. In this study, information gained from the pharmaceutical field is collected and discussed to investigate the probable application in the food industry. 相似文献

Microencapsulation has been developed by the pharmaceutical industry as a means to control or modify the release of drug substances from drug delivery systems. In drug delivery systems microencapsulation is used to improve the bioavailability of drugs, control drug release kinetics, minimize drug side effects, and mask the bitter taste of drug substances. The application of microencapsulation has been extended to the food industry, typically for controlling the release of flavorings and the production of foods containing functional ingredients (e.g. probiotics and bioactive ingredients). Compared to the pharmaceutical industry, the food industry has lower profit margins and therefore the criteria in selecting a suitable microencapsulation technology are more stringent. The type of microcapsule (reservoir and matrix systems) produced and its resultant release properties are dependent on the microencapsulation technology, in addition to the physicochemical properties of the core and the shell materials. This review discusses the factors that affect the release of bioactive ingredients from microcapsules produced by different microencapsulation technologies. The key criteria in selecting a suitable microencapsulation technology are also discussed. Two of the most common physical microencapsulation technologies used in pharmaceutical processing, fluidized-bed coating, and extrusion-spheronization are explained to highlight how they might be adapted to the microencapsulation of functional bioactive ingredients in the food industry. 相似文献

Originally developed as a pharmaceutical technique, fluidized bed coating is now increasingly being applied in the food industry to tune the effect of functional ingredients and additives. Main benefits of such miniature packages, called microcapsules, include increased shelf life, taste masking, ease of handling, controlled release, improved aesthetics, taste and color. However, compared with a pharmaceutical technologist, a food technologist is more obliged to cut production costs and, therefore, should adopt a somewhat different approach to this rather expensive technology. As a consequence, conventional top-spray film coating of food ingredients seems the most feasible. Moreover, the barrier characteristics of a top-spray coating serve most food applications. Nevertheless, numerous variables are involved in film coating and a thorough insight into their action is essential for establishing an appropriate thermodynamic operation point that provides the required process and product quality. Finally, the development of continuous fluidized bed coaters will offer new possibilities. 相似文献

亲脂性活性分子如维生素、脂肪酸和香精油等对氧、热、光等敏感,在食品加工或人体生理运输过程中易被氧化和降解,限制了其在食品工业中的应用。在可用于递送亲脂性分子的技术中,乳状微凝胶颗粒是一类相对较新的软固体颗粒递送体系,其因离散程度的大小和“智能”释放特性而引起越来越多的关注。利用微乳液凝胶颗粒包载亲脂活性分子能够显著提高其理化稳定性,并将亲脂活性分子在靶向位置有效释放以提高其生物利用度。本文通过总结国内外文献,综述了微乳液凝胶颗粒的研究进展,重点讨论了微乳液凝胶颗粒的制备、控制释放特性和主要应用。最后对目前食品脂溶性分子的微乳液凝胶颗粒传递体系的问题和发展进行分析和展望,旨在为微乳液凝胶颗粒的应用提供参考。 相似文献

ABSTRACTControlled release packaging (CRP) is an innovative technology that uses the package to release active compounds in a controlled manner to improve safety and quality for a wide range of food products during storage. This paper provides a critical review of the uniqueness, design considerations, and research gaps of CRP, with a focus on the kinetics and mechanism of active compounds releasing from the package. Literature data and practical examples are presented to illustrate how CRP controls what active compounds to release, when and how to release, how much and how fast to release, in order to improve food safety and quality. 相似文献
