内容記述 | To assure the homogeneity of a reference material for the mycotoxin sterigmatocystin (STE), a study was first conducted to prepare a reference material of rice containing the coloring Food Red 106. Initially, a V-shaped mixer was used to mix Food Red 106 and ground brown rice, but the resulting mixture was non-homogeneous. However, when a Shake- Master was used for the simultaneous grinding and mixing of brown rice with Food Red 106, good homogeneity was achieved. Accordingly, a dried culture of Aspergillus versicolor NRRL5219 and brown rice was ground and mixed with the ShakeMaster. To assess the distribution of the STE an Autoprep^(R) MF-A 1000 mini-column was used to isolate the STE, and 115-120% recovery was obtained. Repeatability (variability within a day) and intermediate precision (variability between days) were good. According to the IUPAC/ISO/AOAC INTERNATIONAL Harmonized Protocol for the Proficiency Testing of Analytical Chemistry Laboratories, a homogeneous candidate reference material was obtained. The particle sizes of Food Red 106, ground brown rice, ground brown rice containing Food Red 106, and ground brown rice containing a non-STE producing culture of A. oryzae were analyzed and they ranged from 3592μm, 13~704μm, 11~704μm, and 16~704μm, respectirely. | |||||||||||
