Abstrak: Kefir fortified with
purple sweet potato can be a health daily drink. The research is aimed to
determine was to identify the best storage period kefir product, to identify
antioxidant capacity, and to evaluate the quality of kefir product at different
storage. This research was conducted for 3 months from 21 February to 21 May
2015 in Technology and Microbiology Laboratory, Faculty of Animal Husbandry and
Biochemistry and Food and Science Technology Laboratory, Faculty of Technology
Agriculture, Udayana University. Methods use in this study was completely
randomized design (CRD), using 5 treatments (0, 1, 3, 5, and 7 days) during
storage and 4 replication. Variables observed were pH, percentage of total
acid, phenol, antioxidant capacity, and IC50. Storage period were non
significantly affected the content of pH, and total acid. Storage period were
significantly affected the content of phenol, antioxidant capacity, and IC50.
Based of this research it could be concluded that the best storage period of
kefir fortified with purple sweet potato was at 3 days with total value of
phenol 37.5798 mg/100 ml GAE, antioxidant capacity 11.3800 mg/L.GAEAC, and IC50
246.81 mg/ml.
