BV Dairy in Shaftesbury has recently installed a YTRON-Z unit from Ytron-Quadro for the smoothing or Stretching of its range of yogurts.
In the YTRON-Z, the yogurt coagulum is subject to an extremely short and intensive burst of shearing which smooths the yogurt. The mechanical action of the YTRON -Z causes stretching of the protein molecules which improves the viscosity of the yogurt. “Yogurt-Stretching” is now associated with the YTRON-Z and has brought about the following advantages, according to the company:
- Improvement in gel stability
- Elimination of syneresis and grit or nodule formation giving a smooth product
- Reduction in the protein content in the milk base by around 0.2%
The number of rotor/stator sets, slot widths and speed is selected based on the composition of the yogurt being processed.
BV Dairy joins the large number of yogurt producers using the YTRON-Z for this application.
