The duration to boil in an electric pressure cooker typically ranges from 5 to 20 minutes, depending on the specific recipe and the amount of liquid. This time frame is significantly shorter than traditional boiling methods due to the increased pressure and temperature inside the pressure cooker. For instance, water boils at around 212°F (100°C) at sea level, but in an electric pressure cooker, the boiling point can reach up to 250°F (121°C) due to the higher pressure. This elevated temperature accelerates the cooking process, allowing for faster boiling times.

The reason for the shorter boiling time in an electric pressure cooker is the combination of increased pressure and temperature. According to the USDA Food Safety and Inspection Service, the boiling point of water increases with pressure, which means that more heat is required to bring water to a boil. In an electric pressure cooker, the sealed environment traps heat, leading to a higher boiling point and, consequently, a faster cooking process. For example, a recipe that might take 30 minutes to boil on the stove can be completed in just 10 minutes in an electric pressure cooker.

Research conducted by the University of Georgia's College of Family and Consumer Sciences indicates that electric pressure cookers can reduce cooking times by up to 70%. This efficiency not only saves time but also energy, as less heat is required to cook the same amount of food. Additionally, the high pressure and temperature can help to preserve the nutrients in the food, making electric pressure cookers a healthier cooking option.

In summary, the boiling time in an electric pressure cooker is typically 5 to 20 minutes, depending on the recipe and the amount of liquid. This time frame is shorter than traditional boiling methods due to the increased pressure and temperature inside the pressure cooker, which accelerates the cooking process and preserves nutrients.
