Comprehensive Stability Study of Vitamin D3 in Aqueous Solutions and . . . The vitamin D3 stability study in aqueous solutions (to evaluate the influence of media, temperature, pH, concentration, light, oxygen, and metal ions on its stability) provided useful information for the formulation of stable vitamin D3 products
Stability of vitamin D in foodstuffs during cooking - PubMed We investigated the retention of vitamin D3 and 25-hydroxyvitamin D3 in eggs, vitamin D3 in margarine, and vitamin D3 and vitamin D2 in bread Our set-up illustrated the cooking methods usually performed in households i e boiling, frying in pan and oven, and baking All experiments were performed three times independently of one another
Influence of Storage Conditions on the Stability of Vitamin D3 and . . . In this study, the influence of storage conditions including light, air, storage temperature, and time on vitamin D 3 retention in fortified canola oil was evaluated Moreover, a kinetic study on vitamin D 3 degradation in the oil was done
Simultaneous Determination of Vitamin D2 and D3 in Milk - Agilent There are various published methods for analysis of vitamins D2 and D3 The high matrix effects in food-based samples are analyzed through the use of an APCI source in LC MS MS methods Despite all efforts, the diverse nature of milk with variable fat content has posed a threat to analytical data
The pre‐analytical stability of 25‐hydroxyvitamin D: Storage and mixing . . . 25‐OH VitD is pre‐analytically stable after long‐term sample storage at −20°C and can be analyzed without vortexing This may be beneficial for both research and diagnostic laboratories Keywords: effect, mixing, pre‐analytical, stability, storage, vitamin D 1 INTRODUCTION Vitamin D is required for normal development and bone health
