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)
Starch nanoparticles were prepared from proso millet starch using a green and facile method combined with enzymolysis and recrystallization. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), differential scanning calorimeter (DSC) and thermal gravimetric analysis (TGA) were used to characterize the(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)
Mechanical, barrier and morphological properties of edible films based on blends of Pea starch (PS) and Peanut protein isolate (PPI) plasticized with glycerol (30%, w/w) were investigated. As PPI ratio in PS/PPI blends increased, the thickness of films decreased, the opacity slightly elevated and color intensified. The addition of PPI to the PS film(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)
Polyphenols are known to have potent antioxidant capacity and other health-beneficial bioactivities. However, extremely low absorption rate of polyphenols restricts their bioactivity in vivo. Development of biopolymer nanoparticle carrier is a promising solution. For the first time, we have successfully prepared worm-like amylopectin nanoparticles (APNPs)(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)
Taro starch nanoparticles (TSNPs) obtained by hydrolysis with pullulanase and the recrystallisation of gelatinised starch were used as reinforcing agents in corn starch films. The influence of TSNPs contents (0.5-15%) on the physical, mechanical, thermal, and structural properties of starch films was investigated. An increase in the concentration of TSNPs(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)
