2.8. Syneresis Measurement. Syneresis index of different
yogurt samples was determined according to the methodology
proposed by Farnsworth et al. [18] with modifications.
Yogurt (20 g)was prepared in centrifuge cups and centrifuged
at 350 ×g (model K-24; Sigma Laborzentrifugen GmbH,
Osterode am Harz, Germany) for 10 min at 4∘C. The clearsupernatant was collected and weighed and syneresis was
calculated according to the following equation [18, 19]:
Syneresis (%) =
weight of supernatant (g)
weight of yogurt sample (g)
× 100%.
