Gelatin isolated from limed split wastes can be a high value product due to its special characteristics and has many potential future applications in Food, functional additives, Food and pharmaceutical industries. Concentrations of sodium hydroxide, sulfuric and acetic acids used in processing gelatin from Narrow barred, Carcharhinus Leucas, Siganus Sutor and Indo Pacific king mackerel skins af...

To take advantage of the by-product catfish bone, gelatin is made as a value added fishery industry, because Gelatin using sapa bovine fish bone has same characteristics gelatin. main ingredient in manufacture marshmallows to improve texture and ebilite. The purpose this study was determine panelists' preference for with addition into conduct chemical quality tests (water content ash content) o...

Keratin solution was separately blended with collagen, gelatin, sericin and starch for films preparation. All the blended films had smooth surfaces without phase separation, except the keratin/ starch blend film. The native keratin film showed small particles embedded in all the film surfaces that resulted in them being rough. The structure of the native keratin film changed from beta-sheet to ...

The Gates photographic film method for pepsin estimation as developed by Gilman and Cowgill measures an activity corresponding to that determined by the hemoglobin method of Anson and Mirsky rather than that resulting from the use of the gelatin viscosity technique. Therefore, the presence of gelatinase is not a source of great error in the gelatin film procedure.

Fish hematological changes during osmotic and cold stress are used to introduce the physiological reactions of the animal to an acute stress. Brook char (Salvelinus fontinalis) were subjected to 1 h of stress before being anesthetized and having blood taken from their caudal vein. Glucose, hemoglobin, hematocrit, and osmolarity were determined in the blood samples. Analyses showed that glucose ...

Parasite communities of fishes are known to respond directly to the abiotic environment of the host, for example, to water quality and water temperature. Biotic factors are also important as they affect the exposure profile through heterogeneities in parasite distribution in the environment. Parasites in a particular environment may pose a strong selection on fish. For example, ecological diffe...

For determining the absorbed dose of ionizing radiation is tissues, it is essential to have materials which behave like tissues. These kinds of materials are usually called phantom. Up to now many different compounds like water, rubber, Perspex etc have been used. Unfortunately, the practical use of each of them has had its own problems. Our suggested gelatin phantom is very similar to soft...

A 10-week feeding experiment was conducted to evaluate the effects of feeding level, energy and protein maintenance requirement of rainbow trout, Oncorhynchus mykiss, fingerling (5.65±0.45cm; 1.42 ±0.25g) by feeding casein-gelatin based purified diet (45% CP; 3.67 kcal  g-1 GE) at six feeding levels 2-7% of BW/day in two equal meals, at 0800 and 1700 h, in triplicate, with 20 fish per trough fi...
