| Abstract [eng] |
Inulin, a linear polysaccharide consisting of fructose units linked by β-(2 → 1) glycosylic bonds, has applications in the food, biotechnology and pharmaceutical industries. The study aims to encapsulate β-carotene using inulin as a food grade material. β-Carotene is a well-known antioxidant and has health-promoting properties. However, it is sensitive to visible/UV light, degrades in the presence of oxygen and is insoluble in water. β-Carotene-inulin particles were fabricated by the complexation method using different β-carotene/inulin ratios. Raman and 1H NMR spectroscopy and the differential scanning calorimetry method were used to confirm the formation of the complex. Based on complexation yield, encapsulation efficiency and loading capacity, the β-carotene/inulin ratios of 1:10 and 1:20 (w/w) were found to be suitable for particle preparation. The water solubility of the complexes was 45–50 mg/mL. The applicability of newly prepared β-carotene-inulin particles was demonstrated in a real food system, that is, apple juice and birch sap. |
