摘要
Four milk-based ice cream samples were produced by heating (65 degrees C) the ingredients at different pressures (0.5, 1.0 bar) and times (5, 30 min). Overrun, melting behaviour, particle size, viscosity and sensory analysis were conducted for each time/temperature combination. The 5-min vacuum application resulted in a reduction of overrun and air bubbles size, whereas ice cream viscosity increased. Opposite outcomes were found for the sample treated with vacuum for 30 min, which also showed a significant fat globule size reduction (<3.0 mu m). Sensory analysis revealed that the use of vacuum improved sweetness, milky and creamy sensations regardless the treatment times.
