Abstract

Abstract Chavil (Ferulago angulata) extract (CE) and microencapsulated chavil extract (MCE) were added to UF- Feta-type Cheese. The aim of this study was to comprising CE and MCE on physicochemical and microbiological properties in cheese. The scanning electron microscope images demonstrate the MCE had elliptical shape. The average size diameter curve of the MCE revealed bimodal distribution with two peaks (1541 and 2222 nm) separately. The hardness value of MCE cheese (212.83 ± 17.63 g) was lower than that of CE (343.67 ± 25.53 g) because of canola oil used in the microencapsulation process. The MCE-cheese showed lower values of acidity (1.67%) in comparison with CE-cheese (1.87%). The viable numbers of Streptococcus thermophilus and Lactococcus lactis were equal among the samples (4.6–4.9 log10 CFU/g respectively). The acid degree value of MCE (2.07 ± 0.21%) and CE (1.83 ± 0.25%) cheese were nearly equal at the end of storage time.
