Preparation and properties of composite films from gelatin and low-methoxyl pectin from simultaneous reversible and permanent polyion-complex hydrogels are presented. Ionic interactions between positively charged gelatin and negatively charged pectin produce reversible physical hydrogels with homogeneous molecular arrangement that improve both mechanical and water resistance but do not alter th...

angelica essential oil (ao), a major pharmacologically active component of angelica sinensis (oliv.) diels, possesses hemogenesis, analgesic activities and sedative effect. the application of ao in pharmaceutical systems had been limited because of its low oxidative stability. the ao-loaded gelatin-chitosan microcapsules with prevention from oxidation were developed and optimized using response...

Angelica essential oil (AO), a major pharmacologically active component of Angelica sinensis (Oliv.) Diels, possesses hemogenesis, analgesic activities and sedative effect. The application of AO in pharmaceutical systems had been limited because of its low oxidative stability. The AO-loaded gelatin-chitosan microcapsules with prevention from oxidation were developed and optimized using response...

In this study, the protein and oleosomes of sesame seeds were extracted individually used to prepare a gel composed gelatin, protein, oleosomes. Mixtures gelatin prepared, with different percentages (0, 10, 20 30% their weight) used. Different amounts in composite samples examined for morphological, rheological, textural properties. The results viscoelastic properties indicated that higher perc...

This study is undertaken to design zinc-stabilized gelatin nano-complexes of tissue-type plasminogen activator (t-PA) for thrombolytic therapy where the t-PA activity can be recovered in the blood circulation upon ultrasound irradiation. Various molecular weights of gelatin were complexed with t-PA by their simply mixing in aqueous solution. Then, zinc acetate, calcium acetate or magnesium acet...

Gelatin cross-linking has recently been discovered to be a very appealing method of producing gelatin-based films. The current research looks at various commercial gelatin (type B) films improve their physical qualities. Bunium alpinum and bunium incrassatum essential oils (EOs) in two quantities (5% 25%) were added the films, which showed substantial biological activity (antibacterial, antioxi...
