Description
|
IAEA 359 Cabbage (Brassica oleracea var. Sabauda) was grown from seed in the vicinity of the Agency’s laboratory in Seibersdorf, Austria. Since this material was originally intended for use as an agrochemical reference material, the seeds were treated with Lindane and Aziprotryne and during the growth of the crop, it was treated with a further eight agrochemical compounds (Metazachlor, Propachlor, Desmetryne, Endosulfan, Bromophos, (Lindane), Fluazifop-butyl, Bitertanol and Trifluralin) [2]. Approximately 6000 Kg of the cabbage was harvested by hand and then cut using an agricultural cutting machine. The stems were removed by hand and 2200 Kg of the material was available for further processing. The raw material was oven dried at 40 °C for several days and then stored in black polythene bags (about 285 Kg). The dried cabbage was ground in an impact pulveriser mill to pass through a 300 µm sieve and extruded into polythene bags. This coarse fraction was then further processed in an air jet mill, resulting in a particle size below 50 µm. Once air jet milled, the material was placed in a large plastic drum and thoroughly mixed by continuous rotation for a 24 hour period. The material was then bottled in acid washed brown glass bottles which were sealed with a polythene cap. Each bottle contained approximately 30 g of the product. The sealed bottles were sterilised at 25 KGy using a 60 Co source, to confer stability by inhibiting any microbial action in the product. |
