纤维素稳定Pickering乳液的研究进展及在食品领域的应用

纤维素作为一种可再生资源，具有来源广泛、绿色环保、可生物降解性、生物相容性等优点。研究发现，由固体颗粒作为稳定剂制备的乳液较传统表面活性剂稳定的乳液具有更高的稳定性，而纤维素凭借其生物相容性、来源广、绿色环保等优点，成为一种良好的Pickering乳液稳定剂，同时纤维素作为一种天然的可食用膳食纤维，在食品领域中具有广阔的应用前景。本文综述不同种类纤维素稳定Pickering乳液的特点，介绍不同处理方式赋予纳米纤维素稳定Pickering乳液不同的性能，并对纳米纤维素基乳液在制备食品级高分子材料、制备新型低热量食品、输送生物活性物质及辅助消化等食品领域的应用进行叙述，为拓宽纤维素基Pickering乳液应用提供参考。

Research Progress on Cellulose-Stabilized Pickering Emulsion and Its Application in Food Field

As a renewable resource, cellulose has the advantages of wide source, environmental friendliness, biodegradability and biocompatibility. It is found that emulsions prepared with solid particles as stabilizers have higher stability than traditional surfactant-stabilized emulsions, and cellulose is an excellent stabilizer for Pickering emulsions due to its biocompatibility, wide source and environmental friendliness and has a broad prospect for application as a natural dietary fiber in the food field. In this article, the characteristics of Pickering emulsions stabilized by different kinds of cellulose and the different properties different treatments impart to nanocellulose-stabilized Pickering emulsions are reviewed. The recent applications of nanocellulose-based emulsions in the food field such as preparation of food-grade polymer materials, preparation of new low-calorie foods, delivery of bioactive substances and auxiliary digestion are described, which can provide a reference for broadening the application of cellulose-based Pickering emulsions.
