This research was done in order to study the effect of packaging films with different permeability on the some of physicochemical properties of rambutan during storage at 10℃. The films used were 0.090 mm low density polyethylene （LDPE）, 0.040 mm polyprophylene and 0.057 mm LDPE compared unwrapped fruits. Fruits were evaluated every 5 days for changes in moisture content, total sugars, vitamin C, hardness and color. Unwrapped rambutan had severe browning after 10 days. Sealed packages especially the LDPE had delayed the development of the browning for 20 days of storage and had the lowest weight loss.展开更多

The novel anti-androgen dimethyl curcumin niosomes were prepared by thin-film dispersion-ultrasonic method, and the prescription composition and preparation process were optimized by single-factor investigation method. Certainly, the solubility and quality evaluation of dimethyl curcumin niosomes were also investigated. The average particle size of prepared dimethyl curcumin niosomes was （310.3＋0.9） nm. The highest encapsulation rate was 88.1%± 1.7%, and the drug-loading amount was 4.03%±1.05%. Moreover, the leakage rate was below 2% within 45 d. Collectively, all these findings indicated that the niosomes, as a vector, could significantly improve the solubility and stability of dimethyl curcumin, offering a theoretical basis for dimethyl curcumin as an anticancer drug in medicine application.展开更多
