[Method] Taking jujube, medlar and soybeam as raw material, the technologies to process compound drinks were studied. The key working procedure was determined. Factors that influenced quali-ty of drinks were studied.[ Result] The best formula was： 30% ：30% ：30% of jujube： medlar： soybean. The color fixative of Vc was 0.02%. The ratio of materials and water was 1 ： 5 mg/ml. The addition of stabilizer xanthan was 0.20%. The addition of white crystal sugar was 6%. [ Conclu-slo] The sensual evaluation of the compound juice of jujube, medlar and soybean was good and the quality achieved national standard.展开更多

[ Method] Various raw materials were dried for different time at 50℃, and then the sticking degree of EGCG effervescent tablets was reviewed. Hereafter, the formula of EGCG effervescent tablets was optimized by orthogonal test. [ Result] Effervescent tablets without sticking were smooth after being dried for 150 rain. The optimal formula of EGCG effervescent tablets was composed of 4% EGCG, 45% citric acid and sodium carbonate （Citric acid： Sodium carbonate = 1.6：1 ）, 20% lactose, 4% L-leucine, 4% sodium cyclamate and 23% orange powder. [Condusion] The prepared EGCG effervescent tablets without sticking has a good effervescence effect and taste.展开更多

Since first reported in 1990, MOFs have attracted extensive attention and the fabrication of MOF membranes has expanded their applications and endowed them with a bright future in various fields. The mass transportation process through MOF membranes is vital during their diverse applications. In this review, the strategies of preparing continuous and well-intergrown MOF membranes are presented firstly.The selective transportation processes of gas molecules, liquid molecules and ions through MOF membranes are discussed in detail, respectively. The effects of pore entrance size, interaction, functional groups decorating on the ligands and guest components on mass transportation have been summarized in this review as well. In addition, MOF membranes with selective transportation performance demonstrate potential in separation, catalysis, energy transformation and storage devices,and so on.展开更多
