An In-Depth Overview of the Structural Properties, Health Benefits, and Applications of Resistant Dextrin

Table 2

Advantages and limitations of different methods to determine the apparent morphology of resistant dextrin.

Methodologies	Advantages	Limitations	References
PLM	(i) Simple preprocessing procedures and low cost; (ii) A quick, clear view of the starch Maltese cross; (iii) Visualization of changes in starch structure during the dextrinization process	(i) Only particle morphology can be observed; (ii) The size and shape of the obtained starch granules are not precise; (iii) To obtain high image contrast requires staining of the sample	Chakraborty et al. [92]; Langenaeke et al. [93]; Tao et al. [94]
SEM	(i) For studying the shape and surface properties of samples; (ii) Relatively easy preparation of specimens; (iii) Higher resolution compared to optical microscopes; (iv) More stereoscopic imaging	(i) Only give qualitative information on the microstructure, not the fine structure of the sample; (ii) Minor differences are not easy to observe; (iii) Inability to observe the hierarchical structure of starch	Chakraborty et al. [92]; Choudhary & Choudhary [95]
