Abstract: In an embodiment, a bloom engine is created that can detect the formation of both fat bloom and sugar bloom in a chocolate product. A Raman spectrometer is used to generate a first or reference spectrum of a chocolate product. Based on peaks of the spectrum known to be associated with sugar and peaks of the spectrum known to be associated with fat, a ratio of sugar to fat for the chocolate product is determined based on the reference spectrum. Later, a second spectrum is generated from the chocolate product, and a ratio of sugar to fat is similarly determined for the second spectrum. Changes in the ratios between the two samples are used to detect fat or sugar bloom. Other features of the bloom engine including removing or reducing bloom from the chocolate product using a laser associated with the spectrometer and applying a design to the chocolate product in bloom using the laser.
