Stability studies of vitamins in three food reference materials
Stability in storage and shipment of retinol, alpha-tocopherol, vitamins B(1), B(2) and C in three foods was studied to assess the feasibility of certifying the vitamin content of three food RMs: whole milk powder (CRM 380), pork muscle (CRM 384) and freeze-dried haricot beans (CRM 383). These were recently certified for major dietary components and major elements. To study short-term stability in shipment, samples were exposed to such high temperatures as may arise during adverse transport conditions. Storage conditions were simulated in a long-term stability study by exposing samples to relatively high temperatures. Interpretation of the long-term stability data was, however, complicated by a dominant analytical variability over the measurement period. This article presents the methods of analysis used in this project as well as the results and conclusions derived from the study.
