New botanical materials are emerging as unconventional sources of starch, increasing their economic value and, therefore, providing a higher starch demand with novel and unique properties for the substitution of traditional starch sources. Overall, starch isolation from roots and tubers is simple and based on breaking vegetal cells to release the starch. Starch extraction from pulses is more complex due to their higher protein and lipid content and smaller starch granules compared to roots and tuber starches. Starch from pseudocereals can be isolated by wet milling. Recently, alternative sources of starch have been proposed, including tree, herbs/shrubs, and fruits; the isolation of starch from these sources involves wet milling procedures in the presence or absence of the chemical solutions. This review summarizes the usual laboratory methods and recent advances in the extraction of starches from roots, tubers, pulses, and pseudocerals. Starch extraction methods from unconventional sources are also described. This review may be useful to guide researchers and technologists from the industry in their choice of better starch extraction methods, presenting the advantages and disadvantages of each method.

提取根，块茎，豆类，假谷物和其他非常规淀粉的方法来源：综述

新的植物材料正在作为非常规的淀粉来源出现，从而增加了其经济价值，因此，提供了更高的淀粉需求，具有新颖独特的特性来替代传统的淀粉来源。总体而言，从根和块茎中分离淀粉很简单，其基础是破坏植物细胞释放淀粉。与根和块茎淀粉相比，由于豆类的蛋白质和脂质含量更高，且淀​​粉颗粒更小，因此从豆类中提取淀粉更为复杂。假谷物中的淀粉可以通过湿磨分离。最近，人们提出了淀粉的替代来源，包括树木，草药/灌木和水果。从这些来源中分离淀粉涉及在有无化学溶液的情况下进行湿磨。这篇综述总结了常规的实验室方法以及从根，块茎，豆类和假蜡质中提取淀粉的最新进展。还描述了从非常规来源提取淀粉的方法。这篇综述可能对指导行业研究人员和技术人员选择更好的淀粉提取方法很有用，并介绍每种方法的优缺点。
