An increased demand for natural products nowadays most specifically probiotics (PROs) is evident since it comes in conjunction with beneficial health effects for consumers. In this regard, it is well known that encapsulation could positively affect the PROs' viability throughout food manufacturing and long-term storage. This paper aims to analyze and review various double/multilayer strategies for encapsulation of PROs. Double-layer encapsulation of PROs by electrohydrodynamic atomization or electrospraying technology has been reported along with layer-by-layer assembly and water-in-oil-in-water (W/O/W) double emulsions to produce multilayer PROs-loaded carriers. Finally, their applications in food products are presented. The resistance and viability of loaded PROs to mechanical damage, during gastrointestinal transit and shelf life of these trapping systems, are also described. The PROs encapsulation in double- and multiple-layer coatings combined with other technologies can be examined to increase the opportunities for new functional products with amended functionalities opening a novel horizon in food technology.
如今，人们对天然产品（尤其是益生菌）的需求不断增加，因为它们对消费者的健康有益。在这方面，众所周知，封装可以积极影响益生菌在食品制造和长期储存过程中的存活率。本文旨在分析和综述益生菌封装的各种双层/多层策略。据报道，通过静电喷雾或电喷雾技术对益生菌进行双层封装，以及通过层层组装和水包油包水（W/O/W）双重乳液来生产多层负载益生菌的载体。最后，介绍了它们在食品产品中的应用。还描述了负载益生菌在胃肠道转运过程中以及这些捕获系统的货架期内抵抗和保持活力的能力，免受机械损伤的影响。通过双层和多层涂层与其他技术相结合来封装益生菌，可以增加具有改良功能的新型功能性产品的机会，为食品技术开辟新的前景。
