Abstract:

The experiment has been made with the quails that fed on the food containing the yeast Rhodotorula rubra with the broken cell walls, to study the pigmentation effect of carotenoid from Rhodotorula r ubra on the yolks of quails. The yolk color step and the carotenoid content of the quail subjects gradually increased, with the color step rising from step 6 to step 15 during 8 days, while the normal group of quails kept the color step 6. The spectrum scanning for the pigment of the yolks has been made with the wave lengths from 360 nm to 600 nm, showing that the quail subjects and the normal group of quails are similar in the wave forms. Using the method of reverse HPLC to analyze the β- carotene content, the result has shown that the β- carotene content of the subjects reached 0. 032 mg/ yolk, increased by 21 times compared with the normal group of quails. The exper imental results have proved that the yeast Rhodotorula rubra is a good natural yolk color pigment and nutritious additive.
