Abstract:
1. A method for forming a textural structure image of a processed food or a raw material for the processed food, the method comprising: freezing the processed food or the raw material for the processed food at −18° C. or less and adjusting a nonfreezing water content of the frozen processed food or the frozen raw material for the processed food to 30% by weight or less, preparing a slice of the frozen processed food or the frozen raw material for the processed food having a nonfreezing water content of 30% by weight or less, staining the slice of the frozen processed food or the frozen raw material for the processed food having a nonfreezing water content of 30% by weight or less with a fluorescent dye having a triphenylmethane skeleton to provide a specimen; radiating an excitation light to the specimen; observing the radiated specimen by use of three or more kinds of monitoring lights including at least a monitoring light (A) having a fluorescence wavelength of 380 nm or longer and shorter than 450 nm, a monitoring light (B) having a fluorescence wavelength of 450 nm or longer and shorter than 560 nm, and a monitoring light (C) having a fluorescence wavelength of 560 nm to 700 nm; and forming an image on the basis of a result of the observation.
