Abstract
Provided is a system (100) for determining the main ingredients of a food recipe. The system comprises a first input (102) for receiving the identity and mass fraction (wri) of each ingredient (i) in the food recipe (r), and a second input (104) for receiving the identity of ingredients of each known recipe of a population of known recipes. The system further includes a controller (106) configured to calculate, for each ingredient (i), the fraction (P(i)) of the population which uses the ingredient. The controller then calculates, using the fraction (P(i)) and the mass fraction (wri), a value (Vri) which positively correlates with the mass fraction (wri) and negatively correlates with the fraction (P(i)). The main ingredients are then determined according to the ingredients which have values (Vri) equal to or greater than a threshold value. Further provided is a cooking appliance (200) which includes the system, a computer implemented method for determining the main ingredients of a food recipe, and a computer program which implements the method.
