A split-type microwave oven comprises a first housing assembly, a second housing assembly, a microwave source module, a microwave shielding and choking member, and a detection device that is used for detecting whether a wave leakage occurs in a microwave heating resonant cavity. The second housing assembly is detachably disposed on the first housing assembly. The first housing assembly is provided with a first microwave shielding member, the second housing assembly is provided with a second microwave shielding member, and the first microwave shielding member is suitable for defining, together with the second microwave shielding member, the microwave heating resonant cavity. The microwave source module is installed on one of the first housing assembly and the second housing assembly. The microwave shielding and choking member is located outside the microwave heating resonant cavity. The split-type microwave oven occupies a small space and is convenient to use.

Described herein are methods for determining the temperature and nutrient content of items heated in a microwave oven. An example method of determining the temperature of the item includes receiving item information; receiving a trained water model; measuring, by an antenna, an emission value from the exterior of the microwave; determining, the power flow into the item based on the trained water model, the item information, and the emission value; and estimating, by the trained water model, a temperature change of the item. An example method of determining the nutrient content includes receiving item information; receiving a trained water model; measuring, by an antenna, an emission value from the exterior of the microwave; determining an emission spectrum from the emission value; and determining, using the emission spectrum, the item information, and the trained water model, a nutrient profile of the item.
