Encapsulation of liquid smoke flavoring in ca …

09/07/2013· Encapsulation is a technique used in foods that may protect some compounds with sensory impact, in particular flavoring as liquid smoke. We used the dripping method, obtaining two different layers for encapsulation of liquid smoke: calcium alginate and calcium alginate–chitosan. The results show that the load capacity of liquid smoke encapsulation reached values above 96 %.

The formation and stability of the superoxide radical …

03/09/2008· For samples that were heated with the yellow flame of a torch (>800°C) and thus fully dehydrated, the rutile sample could be stored indefinitely at room temperature without loss of superoxide signal intensity. With samples that were heated to 115°C, 200°C, or 400°C, and held for 2 hours, superoxide was less stable at room temperature.
