Novel food preservation methods, along with preservatives have been employed to prevent food products from spoilage. There is an increasing demand to substitute synthetic preservatives with natural bioactive compounds since they are safe and environmentally friendly. Bioactive compounds with functional and therapeutic properties are found in foods and have also beneficial physiological and immunological health effects. However, there are some issues associated with bioactive compounds, such as low stability, solubility, and permeability. Encapsulation techniques, especially nano-encapsulation, are a promising technique to overcome these restrictions. A range of the plants' constituents can be converted into bio-nanomaterials. Major plant constituents are polysaccharides which have good biocompatibility properties and therapeutic activities, such as antioxidant, antiviral, anti-inflammatory, anti-allergic, and anti-tumor. Among plant and marine-based polysaccharides, cellulose, starch, alginates, chitosan, and carrageenans have been used as carrier materials to preserve core material. Moreover, many studies indicated that favorable sources such as plant and marine based polysaccharides are emerging. This chapter will cover plant and marine-based polysaccharides for nano-encapsulation and their application in the food industry.
新型食品保鲜方法和防腐剂已被用于防止食品变质。由于天然生物活性化合物安全且环保，因此越来越需要用它们替代合成防腐剂。具有功能和治疗特性的生物活性化合物存在于食品中，对生理和免疫健康也有有益的影响。但是，生物活性化合物存在一些问题，例如稳定性低、溶解度低和渗透性差。包封技术，特别是纳米封装，是克服这些限制的一种有前途的技术。一系列植物成分可以转化为生物纳米材料。主要的植物成分是多糖，具有良好的生物相容性和治疗活性，如抗氧化、抗病毒、抗炎、抗过敏和抗肿瘤。在植物和海洋来源的多糖中，纤维素、淀粉、藻酸盐、壳聚糖和卡拉胶已被用作载体材料来保存核心材料。此外，许多研究表明，植物和海洋来源的多糖等有利来源正在出现。本章将涵盖用于纳米封装的植物和海洋多糖及其在食品工业中的应用。
