Storage of Allergenic Raw Materials

Environmental factors are responsible for the deterioration of the raw materials used to manufacture allergenic extracts. Among these factors, moisture content and storage temperature of the materials play a combined role, responsible for the allergenic stability of raw materials. The proper storage of allergenic raw materials is critical to guarantee a particular shelf-life.

We performed a study to examine the stability of several allergenic raw materials over several years. The materials, stored under various moisture and temperature conditions, were tested at different time-intervals. The results of this study indicate that for maximum shelf-life, raw materials should be stored under conditions of low moisture (<8%) and temperature (<0oC).
