Obtention and characterization a vacuum-dried starch aerogel-type biomaterial from A98 rice (Oryza sativa)

“…Then, the characteristic peaks of starch are observed at 900-1200 cm -1 , attributed to the stretching of C-O and C-H bonds. The signals represent the presence of glucose (Mohammadi & Moghaddas, 2020), and the intensity of the peaks in the wavenumber range 1047-1022 cm -1 is related to the starch crystallinity (Smits et al, 1998;Salgado-Delgado et al, 2022). The peak located in the 1600 cm -1 region has been described in previous works as a result of the bending and stretching of the OH groups in the hydrogen bridges in water (Qin et al, 2016).…”

Structural, thermal, and functional properties of Agave tequilana fructan fractions modified by acylation

“…The introduction of a new functional group caused significant changes in the polarity of each of the samples (p < 0.05). This is attributed to the insertion of lauroyl chloride converting the hydroxyl (OH) groups of the fructan units into hydrophobic esters, hindering the interaction with water molecules, which modifies the solubility and hydrophobicity of the polysaccharide (Salgado-Delgado et al, 2022). Table 2 presents the functional properties evaluated in the unmodified and acylated agave fructans at three different pH.…”

Development of modified cassava starches by ultrasound-assisted amylose/lauric acid complex formation

“…The granular morphology of the starches was analyzed in a scanning electron microscope (JEOL, JSU-5600 LV, Japan). Starch samples were coated in with gold with a thin film sputtering unit (model Desk V, Denton Vacuum) (Salgado-Delgado et al, 2022). Samples were observed under a scanning electron beam column, operating at 10 eV voltage acceleration in an ultra-high-vacuum.…”
