Understanding the nuanced interplay between plant polyphenols and starch could have significant implications. For example, it lead to development of tailor-made starches for specific applications, from bakinag brewing pharmaceuticals bioplastics. In addition, this knowledge contribute formulation functional foods with lower glycemic indexes or improved nutrient delivery. Variations in complexes can be attributed differences molecular weight, structure, even content polyphenols. unique structural characteristics starches, such as amylose/amylopectin ratio crystalline density, also observed effects. Processing conditions methods will always alter formation complexes. As type starch/polyphenol a impact on complex, selection suitable botanical sources starch/polyphenols has become focus. Spectroscopy coupled chemometrics is convenient accurate method rapidly identifying starches/polyphenols screening desired source. these relationships crucial optimizing starch-based systems various food technology pharmaceutical formulations.

Summary In this study, a hybrid system was prepared by mixing rice starch (RS) with different mass fractions (0%–10% dry weight) of soy protein isolate (SPI) to investigate its retrogradation characteristics during storage. The results showed that the addition SPI led an increase in pasting temperature and decrease setback (SB) aging rate ( P < 0.05). When level increased 10%, reached peak 75.28°C, resulting 16.52% regrowth 51.61% rate. analysis hardness secondary structure indicated inclusion resulted less robust gel comparison RS, leading short‐range ordered starch. pore observed be smaller more uniform following SPI. presence hindered recrystallisation granules, consequently delay retrogradation. study have validated positive effect incorporating on anti‐aging properties This serves as foundational basis for enhancing processing attributes RS overall quality starchy food products.
