In Pasteurization milk is heated at 72 Centigrade for ....... seconds*4 points5101520

The correct answer for the duration of heating milk at 72°C during pasteurization is 15 seconds. Pasteurization is a heat treatment process that aims to kill harmful bacteria without significantly affecting the quality of the milk. The time and temperature combination is crucial in ensuring that the milk is safe for consumption while preserving its nutritional value. Generally, the standard practice involves heating the milk to at least 72°C for a minimum of 15 seconds, which effectively reduces the microbial load. Therefore, between the options provided—5, 10, 15, and 20 seconds—15 seconds is the scientifically established requirement for effective pasteurization.
