HPLC Evaluation of the Ascorbic Acid Yield in the Microencapsulation Process

Abstract:

Ascorbic acid (AA) plays an essential role in the human body, and because it can not be synthesized, the daily intake has to be assured by our daily meals. Since is a water soluble vitamin, show low stability while dissolved. In addition, the effect of external factors such as temperature, heating process, pH or oxygen, will promote significant AA losses. In order to avoid these drawbacks, different encapsulation techniques for AA has been evaluated and the effectiveness of the encapsulation was evaluated. Different batches of gluten-free cookies were fortified with microencapsulated AA, and the % of losses was determined by HPLC technique. The protective effect of AA was more evident by spray-drying whereas the highest effectiveness was achieved by lyophilization. Keywords: ascorbic acid, microencapsulation, HPLC
