Abstract

The production of certified reference material (CRM) in stable powdered milk matrix is important to ensure metrological traceability and quality management in the validation of methods and routine laboratory analyzes to ensure the quality of this product. Thus, the objective of the present study was to evaluate the short-term stability of the candidate batch for certified reference material in skimmed milk powder matrix. The work was conducted through a classic study according to the recommendations of ISO Guide 35. The parameters of moisture, lipids and total titratable acidity were evaluated during 21 days of storage. The material was stored at three different temperatures (2-8 °C, 25 °C and 40 °C). The data obtained in the stability study were evaluated through simple linear regression analysis and verified against the criteria established by ISO Guide 35. It was verified that the batch of material produced remained stable for determinations of lipids, moisture and titratable acidity for 28 days at temperatures from 2 to 8 °C, 25 °C and 40 °C.
