Sample Preparation:

Sampleprep ID:SP002592
Sampleprep Summary:After purchase the items are directly taken into a humidity-controlled room and exposure to light was minimized. The foods are prepared following how they are commonly eaten; for example, apples cores are removed, and bananas are peeled. Food items are rinsed with water if the consumed part is exposed; for example, apples are washed while bananas are not. The edible parts are sliced and chopped into small 1 cm^3 pieces with a knife on a glass cutting board. This process is repeated for all six items. About 120 g of each item are frozen at -80C for 16 hrs and after transferred into a freeze dryer (Catalog No. 10-269-56B from LabConco/Fisher) and a dark room for 24 hrs. Afterwards the pieces are put into a coffee grinder (Kitchen Aid, 170W, Model No. BCG111OBO) and pulverized to yield a fine powder. The powder is stored at -80C and 200 mg is shipped in argon filled vials under dry ice to the metabolomics center for analysis. Three vials, technical replicates, for each food item were sent.
