NH(4)(+) concentration in an individual droplet was determined by forming a Liesegang ring on a gelatin film containing NaB(C(6)H(5))(4). The NH(4)(+) concentration (mol L(-1) abbreviated to M) was calculated from the NH(4)(+) amount (mol) ascertained in a droplet using pixel count measurements. The droplet volume (L) was calculated by measurement of the diameter of a droplet print on the gelat...

Coated hard capsules are becoming increasingly important for a number of reasons such as administration of new active ingredients, oral vaccination, colon drug delivery or their use in preclinical and clinical trials. The independency of coating composition on capsules filling is the major advantage of this dosage form. In our study, two types of hard capsules (gelatin and hypromellose) were co...

Blend film of polyvinyl alcohol (PVA) based gelatin was prepared by mixing aqueous solutions of both samples. The mixed aqueous solutions of both samples in different ratios (P1, P2, P3, P4 and P5) were then cast onto silicon paper covered glass plate to form film. These films were then irradiated under gamma radiation (60Co) with different intensities (total dose) like 50, 100, 150, 250 and 50...

The determination of SO(4)(2-) concentration in individual rain droplets can be achieved using a gelatin film containing 5 mM barium chloride and 5 mM barium nitrate. SO(4)(2-) in droplets reacts with barium chloride in the film to form the characteristic Liesegang rings. The areal ratio of the ring to the droplet print (ARRD) on the film is a good indicator for determining the SO(4)(2-) concen...

background: fillet is a popular part of chicken carcass which its high perishability is an economic problem. the present research was designed to study the microbial, chemical, and sensorial properties of chicken fillets coated by gelatin-carboxymethyl cellulose (cmc) film containing essential oil (eo) of bene (pistacia atlantica). methods: the chicken fillets were coated by gelatin-cmc film co...

Abstract Ariid catfish is a demersal fish species with high production rate. Fishbone by-product protein content converted into gelatin. Gelatin can be utilized as an edible film due to its low water resistance and tensile strength so that suitable polymer needed form good film, namely chitosan tapioca starch. This study aimed determine the effect of on characteristics best formulation ariid bo...

1. The electrophoretic velocities of gelatin-, egg-albumin-, and gliadin-covered quartz particles in various alcohol-water solutions are, within the limits employed in usual experimental procedures, proportional to the field strength. 2. The electrophoretic mobilities of small, irregularly shaped quartz particles covered with an adsorbed film of protein in alcohol-water solutions are equal to t...

The effect of ribose-induced Maillard reaction on the physical and mechanical properties of gelatin films was investigated. Bovine gelatin solution (5 g/100 mL) containing glycerol and sorbitol (1:1) was mixed with 20% (R20), 40% ribose (R40), or 40% sucrose (S40) (weight % is based on gelatin dry weight) followed by heating (90oC, 2 h) and oven drying to produce dried gelatin films. R20 and R4...

A model for volume hologram formation in thick dichromated gelatin fih-ns is given. Using the model and a few basic film measurements, we can quantify the index modulation vs. exposure curve. The effects of saturation and dynamic absorption increase during exposure are considered in the generation of spatial harmonics. The effects of exposure with non-unity beam-ratio and multiple incoherent ex...
