Should raisins be refrigerated or frozen

Raisins are suitable for refrigeration and can be frozen for long-term storage. The storage method of raisins mainly depends on the length of storage time, humidity control requirements, and ease of consumption.

Raisins have high sugar content and low moisture content, and refrigeration can effectively inhibit mold growth and maintain a soft texture. The temperature in the refrigerator compartment of a household refrigerator remains stable at around 4 ℃, which can slow down the oxidation rate and prevent raisins from hardening or clumping. For short-term storage, it is recommended to use sealed cans or fresh-keeping bags to isolate moisture and avoid absorbing refrigerator odors. refrigerated raisins can be consumed directly or used for baking without the need for thawing.

Freezing is suitable for storing raisins for more than 3 months, and an environment of -18 ℃ can completely block microbial activity. After being divided into small portions and vacuum sealed, it can avoid repeated thawing and quality degradation. The texture of frozen raisins will become brittle, which can be added directly when they are used to cook Congee or stew. If the softness needs to be restored, they can be warmed back at room temperature for 2 hours. Note that freezing may cause surface sugar to form white frost, which does not affect food safety but may alter the appearance.

Raisins should be stored away from direct sunlight and high temperatures in daily life, and should be consumed within one month after opening. Before refrigeration or freezing, check for moisture and discard moldy raisins. When paired with oats and nuts as healthy snacks, it is recommended to seal them promptly after each use to avoid moisture absorption and spoilage caused by temperature changes. In special circumstances where a large amount of raisins need to be consumed quickly, try making them into raisin sauce or adding them to bread to extend their shelf life.
