This study was aimed at comparing the stability of carotenes (α- and β-carotene) in oil solutions with their stability when spray-dried encapsulation is applied. The carotenes were isolated from carrot. A storage test was subsequently performed. The stability of carotenes in oil solutions was determined with the HPLC method. The color of the samples was also analyzed. The oil solutions of carotenes...
The influence of oil phase concentration on rheological properties and stability of the beverage emulsions with selected hydrocolloids was studied. The emulsions were stabilized by arabic gum, ghatti gum and modified starch. The stability of emulsions was determined by turbidimetric method and laser scattering method. Storage test of emulsions and beverages was carried out for 12 weeks. The apparent...
The aim of this study was to work out a recipe for fruit ice with addition of soy protein isolates. The influence of sorts and dose of hydrocolloids on the physicochemical and sensoric properties of fruit soy ice was studied. The soy and whey proteins were compared as ice stabilizer. The investigations were performed to work out recipes for soy ice containing similar contents of protein as that of...
The aim of this study was to work out a recipe for sterilised soy puddings which, as an analogue of milk pudding, could compose a significant source of the soy protein in the diet. The investigations were performed to work out recipes for sterilised soy puddings containing similar contents of protein as those of based on milk or containing higher contents of soy protein up to 6.25 g in a 150 g portion...
The rapeseed protein preparations were obtained by isolation of proteins from the extracted, non-toasted meal by means of the fractionation and enzymatic modification of proteins with utilisation of membrane techniques. Enzymatic hydrolysis of proteins was performed during extraction by means of Alcalase 2.5L in the portion of 9 AU/kg of the substrate protein. To recover and purify the non-precipitating...
