Peanut protein isolate (PPI) was hydrolysed with alcalase to obtain antioxidant peptides. To purify these peptides, the peanut protein isolate hydrolysates (PPIH) were separated by ultrafiltration (MWCO=3kDa) and the obtained PPIH-II (Mw<3kDa) with higher antioxidant activity was further separated by gel filtration chromatography (Sephadex G-15). After(More)
Sorghum starch and sorghum flour were modified by heat-moisture treatment (HMT) at two different moisture contents, 20% and 25%. The result showed that solubility and swelling power of modified samples decreased. In addition, the pasting viscosities of most modified samples were lower than that of native samples. The onset, peak and conclusion temperatures(More)
To study the control effect of surfactants in the process of formation of starch nanoparticles by self-assembly, different surfactants (sodium dodecyl sulfate (SDS), polysorbate 80 (Tween 80), and sorbitan monooleate (Span 80) were added during the fabrication of waxy corn starch nanoparticles (WCSNPs) and potato starch nanoparticles (PSNPs), and their(More)
To characterize the pea starch films reinforced with waxy maize starch nanocrystals, the mechanical, water vapor barrier and morphological properties of the composite films were investigated. The addition of starch nanocrystals increased the tensile strength of the composite films, and the value of tensile strength of the composite films was highest when(More)
Early indica rice was heat-moisture treated at different temperature (90°C, 100°C and 110°C) for 3h, 5h and 7h at a moisture content of 28%, respectively. The effects of heat-moisture treatment (HMT) on the amylose content, pasting properties, texture properties, solubility and swelling power of early indica rice were studied. After HMT at 110°C for 7h, the(More)
The effect of heat moisture treatment (HMT, 100°C, 10h) on the physicochemical and morphological properties of wheat starch and xylitol mixture (SX) were studied by using Rapid Visco-Analyser (RVA), differential scanning calorimetry (DSC), scanning electron microscope (SEM) and X-ray diffraction pattern (X-ray). The research found that the peak viscosity(More)
Waxy maize starch was treated by a facile and green enzymolysis procedure to fabricate starch nanoparticles (StNPs). The yield of StNPs was raised to 85% by pullulanase treatment, and the preparation duration was two days. Morphology (SEM, TEM), crystalline structure (XRD), thermal gravimetry analysis (TGA), and the group changing (FTIR) of StNPs prepared(More)
Corn starch, potato starch, pea starch were impregnated with ionic gums (sodium alginate, CMC, and xanthan, 1% based on starch solids) and heat-treated in a dry state for 0, 2, or 4 h at 130°C. Effects of the dry heating on paste viscosity (RVA), microstructure and thermal properties were examined. Dry heat treatment with ionic gums reduced the pasting(More)
Proso millet (Panicum miliaceum L.) flour and starch were heated in a dry state at 130°C for 2 or 4 h. The effects of dry heat treatment (DHT) on the pasting, morphological and structural properties of the samples were evaluated. Dry heat treatment had a more significant effect on the pasting viscosity of flour than starch; it increased the pasting(More)
