Abstract:
The churnability of commercial dairy cream as a function of fat globule size from micron to nanometric range (0.17-3.50μm) was investigated. To achieve the lower fat globule size with increased interfacial area various amounts of sodium caseinate (NaCN) (0.15-4.9wt%) or Tween 80 (0.25-1wt%) were added to the cream. Under similar microfluidization and churning conditions, both fat globule size and emulsifier type had a significant influence on the churning time and proportion of fat in buttermilk. In general, churning time and buttermilk fat content were increased above 3.5min and 4.4% fat (for untreated fat globule size), respectively with decreasing average fat globule size irrespective of the type of emulsifier used. The addition of Tween 80 reduced the churning time significantly and also decreased the fat content of buttermilk as compared to NaCN added cream.
