The study explored the plasma-activated water (PAW)-assisted heat-moisture treatment (HMT) on the structural, physico-chemical properties, and in vitro digestibility of extrusion-recrystallized starch. Native starch of hausa potatoes underwent modification through a dual process involving PAW-assisted HMT (PHMT) followed by extrusion-recrystallization (PERH) using a twin-screw extruder. The PHMT sample showed surface roughness and etching with a significantly greater (p ≤ 0.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disease in aged populations. Aberrant amyloid-beta accumulation is a common pathological feature in AD patients. Dysfunction of autophagy and impairment of α7nAChR functioning are associated with enhanced amyloid-beta (Aβ) accumulation in AD patients.

The consumer demand for safe, "healthy," and premium foods, preferably with an extended shelf-life; demand for easy packaging; and choice for more sustainable food packaging have contributed to the development of novel packaging technologies. The application of adequate packaging materials has recently become a major post-harvest challenge concerning the control of fungi and mycotoxin. This review will describe the current antifungal packaging technology involved to prevent the contamination of fungi and mycotoxin, along with the characteristics and mechanism of action in food products.

In this study, the effect of chemical modifications such as oxidation, esterification and crosslinking was investigated alone and in combination with microwave irradiation on a non-conventional starch with 76% starch yield acquired from the trunk of matured talipot palm. The single- and dual-modifications imparted significant changes in the morphological, crystalline, pasting and rheological properties and digestibility of talipot starch. Characteristic peaks were observed in single- and dual-oxidized, esterified and crosslinked starches indicating their respective functional groups.

Article Synopsis
  • Talipot starch, sourced from the stem pith of the talipot palm, has a high yield of 76% and underwent three thermal treatments (dry-heat, heat-moisture, and autoclave) before phosphorylation.
  • Phosphorylation combined with thermal treatments significantly increased the phosphorus content and crosslinking degree, with the autoclave pretreatment resulting in the highest degree of crosslinking and notable changes in starch granule structure.
  • The modified starches exhibited decreased amylose content and crystallinity, with dry-heat treated samples showcasing improved light transmittance and stronger gel properties, while autoclave treatment yielded the highest resistant starch content.

Article Synopsis
  • Researchers treated starch from the talipot palm trunk with varying concentrations of citric acid to create citrate starch and analyzed its properties.
  • The treatment led to the formation of an ester bond, as indicated by a new peak in FTIR spectra, while decreasing the relative crystallinity of the starch significantly.
  • Results showed reduced gelatinization parameters and lower general digestibility, but increased amounts of slowly digestible starch and resistant starch after citric acid treatment.

Kithul starch was treated by EN (energetic neutral nitrogen) atoms at 6 W,12 W and 18 W for 15 min and incorporated lauric acid for the development of starch-lauric acid inclusion complexes. EN atoms treatment significantly (p ≤ 0.05) increased the complex index (CI).

Differential regulation of Brn3b is essential for the Retinal Ganglion Cell (RGC) development in the two phases of retinal histogenesis. This biphasic Brn3b regulation is required first, during early retinal histogenesis for RGC fate specification and secondly, during late histogenesis, where Brn3b is needed for RGC axon guidance and survival. Here, we have looked into how the regulation of Brn3b at these two stages happens.
