摘　　要：将生物活性物质封装于纤维素稳定的乳液载体中,可以有效实现功能成分的封装保护、分散利用和运载释放。纤维素的结构特性使其在提高乳液稳定性的同时,也为乳液体系的荷载和释放创造了广阔的设计空间。鉴于此,本文从纤维素乳液的稳定机制、稳定乳液载体的纤维素类型、体系负载的主要生物活性物质及影响其释放的主要因素出发,对基于纤维素稳定乳液的生物活性物质运载体系研究进展进行了系统综述。本文重点阐明了纤维素乳液在功能因子的递送过程中,由其自身高长径比及高机械强度的特性调节的乳液系统释放过程及相关的控释与缓释机制,以期为食品级生物活性物质递送体系的开发利用提供借鉴与参考。研究证实,纤维素稳定的乳液载体可以在改善活性组分的分散性及氧化稳定性的同时,控制其负载的功能因子的释放,进一步提高活性组分的生物利用度。然而,其在食品体系中的安全性评价等方面还存在广阔的研究空间,相关毒理学试验亟待开展。Protection,dispersion and delivery of the functional components can implement in the emulsion-encapsulating systems.Among the stabilizers of the emulsion,specific structure of the cellulose may improve the stability of the system,and supplying the utilization of the bioactive substances on encapsulation and release.Therefore,the recent advances on stabilizing mechanism,cellulosic materials,properties of bioactive substances and factors affecting on the release of cellulosic emulsion-encapsulating systems are summarized in this review.In addition,the paper focuses on the release process and regulated mechanism of cellulose,which shows high length-diameter ratio and mechanical strength in the emulsion-delivery system of bioactive substances,and providing reference for the development of the food-grade delivery system.Studies indicates that cellulose-stabilized emulsion can improve the dispersion and oxidation stability of the bioactive substances,while controlling the release and improving the bioavailability of the functional factors.However,there is still vast research space for its safety evaluation in the food system,and related toxicological experiments urgently need to be carried out.
