How to store raisins to extend their shelf life

Raisins are dried grapes that are rich in fiber, antioxidants, iron, and potassium. They make a great snack or addition to salads, oatmeal, cookies, and cakes. But how do you store raisins properly to prevent them from spoiling or losing their flavor and texture?

The key to storing raisins is to keep them away from moisture, heat, light, and oxygen. These factors can cause raisins to become moldy, hard, or rancid over time. Here are some tips for storing raisins to keep them fresh and delicious for longer:
  • Store raisins in an airtight container or bag. This will prevent moisture and oxygen from entering and affecting the quality of the raisins12. You can use glass jars, plastic containers, ziplock bags, or vacuum-sealed bags for this purpose.
  • Store raisins in a cool and dry place. The ideal temperature for storing raisins is between 10°C and 21°C. You can store them in your pantry, cupboard, or basement as long as they are away from direct sunlight and heat sources. Avoid storing them near stoves, ovens, microwaves, dishwashers, or radiators.
  • Store raisins in the fridge or freezer for longer shelf life. If you want to extend the shelf life of raisins beyond 6 months, you can store them in the fridge or freezer. This will slow down the oxidation process and keep the raisins plump and moist. Make sure to use an airtight container or bag when storing them in the fridge or freezer.
  • Use an oxygen absorber or desiccant packet when storing raisins long term. These packets help remove excess oxygen and moisture from the container, which can prevent mold growth and spoilage. You can place these packets directly on top of the raisins inside the container. They are safe to use with food products.
  • Check your raisins regularly for signs of spoilage. Even if you store your raisins properly, they may still go bad over time due to natural degradation. Some signs of spoilage include mold growth (white fuzzy spots), rancid smell (sour or musty), discoloration (brownish), hardening (shrunken), or insect infestation (tiny holes). If you notice any of these signs on your raisins discard them immediately.

By following these tips for storing raisins you can enjoy their sweet taste and health benefits for longer periods of time.
