Raw milk procured from the Experimental Dairy Plant of
the Institute was standardized to 1.5% fat and 8.5% SNF.
The milk was homogenized at 65 °C in a two-stage APV
Crepaco homogensier operated at 1,500/500 psi and mixed
with sugar at 10% (selected based on preliminary sensory
investigations). The drink was pasteurized at 85 °C for
20 min, followed by cooling to 15 °C. Preliminary studies
were conducted to select a suitable flavour; the flavours
studied included conventional flavours (cardamom and
rose) and non-conventional flavours (orange and pineapple).
The level of various flavours and colours used for selection of
the appropriate flavour for the carbonated FDD is outlined in
Table 1. Based on these prelimnary studies, cardamom was
selected as the flavour for the beverage. The flavoured dairy
drink was filled into sanitised glass bottles of 200 ml
capacity for carbonation and storage.
