Abstract
A quality evaluation method and apparatus for non-bran rice evaluate quality or taste of non-bran rice by identifying proportions of a hull layer, an aleurone layer, an endosperm layer, which adhere to a surface of the non-bran rice according to luminance levels of self-emitted fluorescence obtained by irradiating the non-bran rice with excitation light.

A quality evaluation method for non-bran rice for performing quality evaluation of non-bran rice products which are made by performing non-bran processing for polished rice after hulling, wherein quality is evaluated by simultaneously identifying a quantitative proportion of each of parts of a hull layer, an aleurone layer and an endosperm layer, which adhere to surfaces thereof, according to a difference in luminance of self-emitted fluorescence obtained by irradiating measurement objects with excitation light.
A quality evaluation apparatus for non-bran rice for performing quality evaluation of non-bran rice products which are made by performing non-bran processing for polished rice after hulling, said apparatus comprising:
- an excitation light source for irradiating measurement objects with excitation light;
- measurement object holding means for holding the measurement objects at a measurement position;
- light receiver means for obtaining luminance of self-emitted fluorescence obtained from transmission light or reflection light from said measurement objects;
- arithmetic operation and control means for calculating a quantitative proportion of each of parts of a hull layer, an aleurone layer and an endosperm layer, which adhere to surfaces of said measurement objects, and calculating quality or a taste value of the non-bran rice;
- and
- display means for displaying values arithmetically operated with the arithmetic operation and control means.
A method for performing quality evaluation of non-bran rice made by performing non-bran processing for polished rice after hulling, comprising the steps of:
- obtaining a quantitative proportion of a hull layer adhering to a surface according to luminance of self-emitted fluorescence obtained by irradiating said non-bran rice with excitation light;
- obtaining ingredient proportion of an aleurone layer by picking up an image of said non-bran rice after performing degreasing operation by an organic solvent for said non-bran rice, and performing image processing;
- obtaining a quantitative proportion of an endosperm layer based on said obtained quantitative proportions of the hull layer and the aleurone layer;
- and
- performing quality evaluation of the non-bran rice based on said obtained quantitative proportions of the hull layer, aleurone layer and endosperm layer.
