Abstract
Sažetak Rogač kao tradicionalna mediteranska kultura od davnima se koristi u prehrani ljudi, a nove znanstvene spoznaje ukazuju na veliki potencijal rogača u proizvodnji različitih prehrambenih proizvoda. Brašno sjemenki rogača (E 410) upotrebljava se dugi niz godina u prehrambenoj industriji kao sredstvo za ugušćivanje i stabiliziranje različitih prehrambenih proizvoda. Iz svega navedenog u ovom radu pokušala su se odrediti neka osnovna fizikalno-kemijska svojstva (pH, gustoća, indeks loma) kao i reološka svojstva (viskoznost) komercijalno dostupnog praha komiškog rogača u otopinama kiselina koje se često koriste u prehrambenoj industriji (mliječna, octena i limunska kiselina). Ispitivanja su provedena u 3% otopinama kiselina uz dodatak praha rogača u rasponu od 5 g/L do 25 g/L te pri temperaturama od 25°C do 80°C. Prah rogača u otopinama mliječne i octene kiseline pri 60°C stvara umreženiju strukturu koja je odgovorna za povećanje viskoznosti navedenih otopina. Isto tako prah rogača stvara viskoznije otopine pri pH vrijednostima višim od 2.
Abstract (english)
The carob as a traditional Mediterranean culture has long been used in human nutrition, and new scientific knowledge points to the great potential of carob in the production of various food products. Carob meal (E 410) has been used for many years in the food industry as a means of thickening and stabilizing various food products. From all of the above, some basic physicochemical properties (pH, density, refractive index) and the rheological properties (viscosity) of commercially available carob powder in acidic solutions commonly used in the food industry (lactic, acetic and citric) were conducted. The tests were carried out in 3% acid solutions with the addition of carob powder in the range of 5 g / L to 25 g / L and at temperature range from 25° C to 80 °C. The carob powder in lactic and acetic acid solutions at 60 ° C creates a more cross-linked structure responsible for increasing the viscosity of these solutions. Also, carob powder creates more viscous solutions at pH values higher than 2.
