Resistant starch (RS) plays a key role in providing metabolic and colonic health benefits. In particular, RS type III (RS) is of great interest because of its thermal stability and its preserved nutritional functionality. RS can be prepared by physical treatment, including high hydrostatic pressure, ultrasound, extrusion, autoclaving, microwave cooking, and heat-moisture treatment.

All processed pea starch was transformed from a C- to a B-type crystalline structure. The power law exponent (α) ranging from 1.

The size exclusion chromatography (SEC) results showed that UL-RS, RL-RS, and GL-RS (Group A samples) exhibited higher values of M and R¯ than FL-RS, ML-RS, AL-RS (Group C samples), and CL-RS (Group B sample). In parallel with the SEC result, other structural characteristics followed similar trends, where Group C samples exhibited the lowest values of double helix content and crystallinity by C NMR, and degree of order/double helix by FT-IR.
