Raw ginger was introduced to a series of composite antioxidants. The specimens performed better efficiency than ordinary antioxidants while extracting vitamin C from strawberry. The results suggested that, by employing raw ginger composite antioxidant, the reservation of vitamin C could be 91.63% in washing process and 76.68% in squeezing process respectively. Furthermore, in squeezing process, the reservation of vitamin C reached 84.78% while the concentrate of raw ginger antioxidant was 0.03%. The both deposits performed perfect synergy effectively. Raw ginger composite antioxidant could be the well agent to extract vitamin C from fruit.

Mesoporous V 2 O 5 @TiO 2 composites were fabricated by an ultrasonic method with V 2 O 5 sol as the guest precursor. The prepared materials were characterized by powder X-ray diffraction, field emission-scanning electron microscopy, transmission electron microscope, X-ray photoelectron spectroscopy, UV-Vis spectroscopy and nitrogen sorption analysis. The results indicated that V 2 O 5 nanoparticles dispersed well on/into the porous structure of TiO 2 matrix. The composites presented typical IUPAC IV isotherms with type H 2 hysteresis loops, revealing the mesoporous structure. It was observed that V 2 O 5 loading led to red shift of the absorption edge to 540 nm and reduced the band gap < 3.0 eV. The V 2 O 5 @TiO 2 composites with V/Ti molar ratio of 0.1 exhibited outstanding degradation efficiency of gaseous benzene.
