in this study, the optimum combination of major factors affecting the acceptability of whey-based ricotta cheese i.e. fat at three levels (0, 5, 10%), salt at three levels (0, 1, 2%), and starter culture at two levels (0, 3%) was determined in a complete randomized design method with a factorial experiment. ricotta cheese trials made by mixing whey and milk in a ratio of 5:1 were then organ...

Background: Environmental problems of the plastic materials used in food packaging and the demand for food quality improvements lead to the development of packaging in natural materials. Edible films such as calcium alginate extend the shelf life by acting as a selective barrier against moisture and oxygen. The main objective of this study was to explore a calcium alginate based edible film to ...

introduction: 99mtc-trodat-1 is a promising new radiopharmaceutical with the potential for routine use as the radiopharmaceutical for dopamine transporters scintigraphy as far as its image quality and daily availability are concerned. here we describe the development of a freeze-dried kit formulation based on the tricine exchange labeling approach for the preparation of this radiopharmaceutical...

objective anti-rh d igg is used for the prevention of anti-d antibody production in rh- individuals who have been exposed to rh+ red blood cells. the stability of igg preparations as a solution is low, with a shelf life of a year or more. formulation of anti-rh d igg as a lyophilized preparation would decrease its degradation rate and increases its shelf life. the objective of this study was to...

introduction: the ability to accurately measure forces produced by orthodontic appliances during orthodontic treatment is desirable. the aim of the present study was to compare forces measured by mechanical formulae designed with a software program and those experimentally measured by a dynamometer to find a scientific way to determine the exact amount of activation needed for applying a force ...

in this study, tretinoin microemulsion has been formulated based on phase diagram studies by changing the amounts and proportions of inactive ingredients, such as surfactants, co-surfactants and oils. the effects of these variables have been determined on microemulsion formation, particle size of the dispersed phase and release profile of tretinoin from microemulsion through dialysis membrane. ...

shampoos are products which remove surface grease and dirt from the hair shaft and scalp. the cleansing or detergent action of a shampoo is a primary function. however, the foaming characteristic of a shampoo has an important role in its acceptability. often alkanolamides are used for the formation of a stable foam; but because of producing nitrosamines, they are potentially carcinogenic compou...

in recent decades, as the result of industrial life, consuming fried and fast foods have increased significantly. excessive use of fat, especially saturated fats and trans fatty acids is one of the important factors that increases heart diseases, weight gain, and cancers. therefore, using effective methods for decreasing fat absorption not only retains desirable features but also seems essentia...
