nifedipine (nif), a 1,4-dihydropyridine calcium channel antagonist, undergoes photo-degradation to dehydro-nifedipine (dnif) upon exposure to ultraviolet (uv) light and to the nitroso analogue of dehydro-nifedipine (ndnif) when exposed to sunlight or some kinds of artificial lights. nif photo-degradation products do not contribute to clinical activity, thus prevention of photo-degradation of ni...

the aim of this study was to investigate the influence of various treatments with filter-aids on pomegranate juice quality. the pomegranate used in this study was malas variety. different treatments in cold clarification method attempted were pectolitic enzyme, pectolitic enzyme-gelatin-bentonit, pectolitic enzyme-gelatin-silica sol, pectolitic enzyme-gelatin-bentonit-silica sol, gelatin-benton...

Purpose: Recurrent aphthous stomatitis (RAS) is the most common painful ulcerative disease of oral mucosa happening in ~20% of people. Aimed to develop Myrtus communis L. (Myrtle) containing oral patches, we applied box-behnken design to evaluate the effect of polymers such as Polyvinyl pyrrolidone (PVP), Gelatin, Methylcellulose (MC) and Pectin. Methods: The patches properties such as tensile ...

It is a recognised phenomenon that mixtures of biopolymers in aqueous solution may result in the formation of a two-phase system. Increasingly biopolymers are being used together in food production. Therefore i t is important to understand the conditions and concentration limits that result in phase separation. Gelatin and pectin are important food polymers having the functional properties of g...

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...

The article is devoted to the expansion of assortment list raw materials in technology food products and use pectin-containing fruit desserts. purpose improve dessert by using semi-finished (puree, jelly juice) from blackcurrant, gooseberry, cranberry, chaenomeles fruits enrich nutritional biological value, structural mechanical properties finished maximize resource potential materials. chemica...

Abstract The food packaging sector is focused on developing innovative materials to enhance safety and quality while reducing environmental impact. Accordingly, this study aimed develop based bovine gelatin (G) blended with crude sweet orange juice pomace pectin (SOPP) at different ratios (G/SOPP = 85/15, 65/35, 50/50, w/w). obtained SOPP was highly methylated exhibited antioxidant antibacteria...

PURPOSE The aim of this study was to prepare the optimized oral paste formulation of Triamcinolone acetonide intended to be used in aphtous stomatitis. METHODS Plastibases were prepared using mineral oil and polyethylene (95:5). Oral paste formulations were prepared with different mixtures of three hydrocolloids solids, including gelatin, pectin and sodium carboxymethylcellulose, with differe...
