Physicochemical Properties of Various Shellac Types
Shellac in its acid form undergoes aging, resulting in the change of its physicochemical properties. Therefore, various shellac types were investigated as free films prepared from ammoniacal solutions and as micronized powder in its acid form. Due to its acidic character, shellac shows a pH-dependent solubility. The dissolution properties of shellac films prepared from ammoniacal solution were ...
متن کاملFatty acids profile and physicochemical properties of various shortenings formulated with palm oil
Shortenings are a mixture of one or more vegetable edible oil with partial hydrogenation in mixed with or without animal fat. In this study, three formulations of shortenings, with the best commercial and technological properties were prepared. Increasing consumption of shortenings at the human daily diet, with low adverse coronary effects in human daily diet, three formulations prepared using ...
متن کاملPhysicochemical Characteristics of Various Milk Samples
Milk is an important source of all basic nutrients required for mammals including human beings. The study was conducted to evaluate physiochemical quality of milk samples in selected dairy plant of Iran. Various physiochemical properties of milk were analyzed by Lactostar analyzer and compared to the related standards. Also another major concern of this study was to consider the presence of mel...
متن کاملEffects of Various Salts on Physicochemical Properties and Sensory Characteristics of Cured Meat
This study was carried out to investigate the effects of refined, solar, and bamboo salt on the physico-chemical properties and sensory characteristics of cured pork loin. Moisture, protein, fat, and ash content, lightness, yellowness, cooking yield, and color, juiciness, and tenderness of sensory properties on curing pork loin exhibited no significant differences regardless of the nature of sa...
متن کاملEffect of Various Polymers Concentrations on Physicochemical Properties of Floating Microspheres
Floating microspheres have emerged as a potential candidate for gastroretentive drug delivery system. For developing a desired intragastric floatation system employing these microspheres, it is necessary to select an appropriate balance between buoyancy and drug releasing rate. These properties mainly depend on the polymers used in the formulation of the microspheres. Hence it is necessory to s...
