[Analysis of soluble Ca content in banana pulp based on pretreatment of digestion model in vitro].

In the present paper, soluble Ca content in banana pulp was analyzed with pretreatment of digestion model in vitro. All the samples were digested by strong acid (perchloric acid and nitric acid with 1 : 4 ratio) and determined by AA700 flame atomic absorption spectrophotometry (FAAS). Meanwhile, the reproducibility of the analytical method was investigated.

[Analysis of primary elemental speciation distribution in mungbean during enzymatic hydrolization].

In the present paper, trace elements contents of cuprum, zincum, manganese and ferrum in mungbean and their primary speciation distribution during enzymatic hydrolization were investigated with ICP-AES OPTIMA 5300DV plasma emission spectroscopy. The trace elements were separated into two forms, i.e.

Self-assembled natural rubber/silica nanocomposites: Its preparation and characterization.

A novel natural rubber/silica (NR/SiO) nanocomposite is developed by combining self-assembly and latex-compounding techniques. The results show that the SiO nanoparticles are homogenously distributed throughout NR matrix as nano-clusters with an average size ranged from 60 to 150 nm when the SiO loading is less than 6.5 wt%.
