In the present research work, esterified nanoparticles with 2-octen-1-ylsuccinic anhydride were synthesized from waxy corn starch, to our knowledge for the first time, in a single step of ultrasonic treatment. First, the ultrasound time to produce non-esterified nanoparticles was studied. The results showed that non-esterified nanoparticles had sizes ranging from 63 to 48 nm, as well as polydispersity indexes (PDI) ranging from 0.458 to 0.224 and ζ-potential values ranging from -16 to -24 mV in ultrasonication times ranging from 20 to 100 min. Succinylated nanoparticles were obtained at 80 min with two degrees of substitution i.e., 0.003 and 0.01, hydrodynamic sizes of 57 and 83 nm, PDI of 0.479 and 0.91, and ζ-potential values of -6.27 and -14.03 mV, respectively. The succinylation of nanoparticles was confirmed by FTIR spectroscopy, and it was possible to elucidate the conversion of amylopectin molecules into amylose blocks. The nanoparticles showed stability during storage in aqueous suspension at 4 °C. By means of the ultrasonic technology, destructuring of the waxy corn starch and, at the same time, the succinylation of the nanoparticles in a total time of 120 min was effectively achieved.

Phenolic compounds with antioxidant properties are highly sensitive molecules, which limits their application. In response, extruded esterified starch has been proposed as efficient encapsulating material. In this work, we aim to describe the encapsulation of red sorghum phenolic compounds by spray drying using extruded phosphorylated, acetylated and double esterified sorghum starch as wall material. Their respective encapsulation yields were 77.4, 67.4 and 56.8 %, and encapsulation efficiency 91.4, 89.7 and 84.6 %. Degree of substitution confirmed esterification of the sorghum starch and Fourier transform infrared spectroscopy showed the significant chemical and structural changes in the extruded esterified starch loaded with phenolic compounds. Microcapsules from phosphorylated sorghum starch showed the highest endothermic transition (173.89 °C) and provided a greater protection of the phenolic compounds during storage at 60 °C for 35 days than the other wall materials. Extruded esterified sorghum starch proved to be effective material for the protection of phenolic compounds due to its high encapsulation efficiency and stability during storage.

Type 2 diabetes mellitus (T2DM) and cancer are significant contributors to morbidity and mortality worldwide. Recent studies have increasingly highlighted the potential of phytochemicals found in plants and plant-based foods for preventing and treating these chronic diseases. Mexico’s agrobiodiversity provides a valuable resource for phytochemistry. This review presents an examination of essential phytochemicals found in plants and foods within Mexican agrobiodiversity that have shown promising anti-cancer and anti-diabetic properties, including their roles as antioxidants, insulin sensitizers, and enzyme inhibitors. Notable compounds identified include flavonoids (such as quercetin and catechins), phenolic acids (chlorogenic, gallic, and caffeic acids), methylxanthines (like theobromine), xanthones (such as mangiferin), capsaicinoids (capsaicin), organosulfur compounds (like alliin), and various lipids (avocatins). Although these phytochemicals have shown promise in laboratory and animal studies, there is a significant scarcity of clinical trial data involving humans, underscoring an important area for future research.
