Enzymatic hydrolysis and self-assembly are considered promising methods for preparation of starch nanoparticles (SNPs) because they are environmentally friendly, and time- and cost-effective. These methods are based on the self-assembly of short-chain glucans released from the α-1,6 bonds in amylopectin. Since their discovery, many studies have described the structural and physicochemical properties of self-assembled SNPs. Self-assembled SNPs can be prepared by two methods: using only the soluble portion containing the short-chain glucans, or using the whole hydrolyzate including both insoluble and soluble fractions. Although the structural and physical properties of self-assembled SNPs can be attributed to the composition of the hydrolyzates that participate in self-assembly, this aspect has not yet been discussed. This review focuses on SNPs self-assembled with only soluble short-chain glucans and addresses their characteristics, including formation mechanisms as well as structural and physicochemical properties, compared with SNPs prepared with total hydrolyzates.
酶促水解和自组装被认为是制备淀粉纳米颗粒（SNP）的有前景的方法，因为它们环保、省时且经济高效。这些方法基于从支链淀粉中的α-1,6键释放的短链葡聚糖的自组装。自发现以来，许多研究描述了自组装SNP的结构和物理化学性质。自组装SNP可通过两种方法制备：仅使用含有短链葡聚糖的可溶部分，或使用包括不溶和可溶部分的全水解产物。尽管自组装SNP的结构和物理性质可归因于参与自组装的水解产物的组成，但这方面尚未得到讨论。本综述聚焦于仅由可溶短链葡聚糖自组装的SNP，并与用全水解产物制备的SNP相比，阐述其特性，包括形成机制以及结构和物理化学性质。
