To provide a refrigerator capable of maintaining nutrient components/pigment components which food originally has.

When a door 7 is closed, a container 6 is in a position A in Figure 4, and an antioxidant component is emitted from fine holes 9 of an antioxidant emission unit 8. When a user opens the door 7 and pulls out the container 6 to an arrow B direction, the container 6 moves to a position C, and the food is taken out. The antioxidant emission unit 8 is inclined, a granular antioxidant agent 10 inside the antioxidant emission unit 8 moves in many directions, and particles in a surface part of the antioxidant emission unit 8 and inside particles are replaced to secure a new emission face. Thereby, the antioxidant component emitted from the fine holes 9 does not stop and is successively emitted.
