Title: Method and device for judging freshness of egg
Inventor: NAKANO TAKAYUKI
IPC: G01N21/64
Filed: 1993-03-23
Abstract: PURPOSE:To nondestructively judge the freshness of eggs without giving chemical and physical influence to their contents by applying an ultraviolet ray to an egg with shell and measuring the intensity of red fluorescence generating on the surface of the egg. CONSTITUTION:When an ultraviolet ray is applied to an egg placed in a sample fixing part 3 by using a light source 1 consisting of a long wavelength type ultraviolet lamp with a blue filter, a small amount of protoporphyrin which is included in a cuticular layer made of amorphous covering film and an egg- shell is excited, and a red fluorescence is generated. The intensity of the fluorescence becomes weak as the freshness of the egg is degraded. It is because the cuticular layer which existed on the surface of the egg-shell during oviposition is peeled off gradually with time elapse and the protoporphyrin amount included therein is reduced as well. Then, the generated fluorescence is received by a light receiving part 2, the output that the obtained minute current is amplified by an amplifier 4 is displayed on a display part 5 and it is also inputted to a judgement processing part 6 such as a computer, etc. Therefore, the result is compared with an optionally preset reference value to judge the freshness of the egg.
