Comments:	In this trial we used our Vibratory Micro Mill PULVERISETTE 0 with cryo-box and stainless-steel grinding set. We programmed an amplitude of 3,0 mm. We took a few grams of the pre-cut pumpkin sample as a batch. The pre-crushed sample as well as the grinding set were pre-embrittled and/or cooled with the help of nitrogen before grinding. The sample was finally placed in the grinding set and ground by an amplitude of 3,0 mm with continuous addition of small portions from liquid nitrogen for 1.5 minutes. The sample was ground to a fine powder which after evaporation of the liquid nitrogen became a paste again. The grinding set was cleaned with hot water and a dishwashing detergent.
