Enkapsulasi Dan Stabilitas Pigmen Karotenoid Dari Neurospora Intermedia N-1 (Encapsulation and the Stability of Carotenoids From Neurospora Intermedia N-1)

Neurospora sp, a species of fungi was reported containing the carotenoid pigments, the secondary metabolite of the yellow, orange or red-orange pigments group. On this research, the carotenoid pigments of Neurospora intermedia N-1 has been encapsulated by a copolymer of gelatin-maltodextrins. The encapsulated products were dried by a spray drier and the carotenoid powder was determined its stability to the storage influence at RH 20-30%, for 5 weeks. Encapsulation product of carotenoids extract obtained the GME powder with EY value± 48%. Microencapsulation of this extract was increased the water solubility and stable at RH 20-30% condition, the stability was decreased start at the third week. HPLC analysis of GME powder showed the decreasing of β-carotene about 30%, after storage for 5 weeks. SEM analysis of GME powder showed the globular shape and dents on the surface of particles, with size ±1 µm
