Foodstuff sensing appliance

Abstract:

An appliance includes a temperature control system, a light source, and a spectrometer. The spectrometer works in conjunction with the light source to obtain a measured value of a foodstuff. The measured value is at least one of an absorbance value, a transmittance value, and a reflectance value. The measured value from the foodstuff is compared to a reference value for the foodstuff.
