The Importance of Proper Storage for Mastic Gum
Proper storage is critical for maintaining the quality and integrity of mastic gum, a natural resin derived from the Pistacia lentiscus tree. Unlike synthetic chewing gums, mastic gum is sensitive to external factors such as temperature, humidity, and light. When stored incorrectly, especially in high temperatures, it can soften, clump together, and even turn yellowish due to oxidation. These changes can impact its texture and flavor, though they don't necessarily make the gum unsafe to consume. Refrigerating mastic gum is a proactive step that can help mitigate these issues, preserving its unique properties for a better user experience.
Why Mastic Gum Is So Temperature-Sensitive
Mastic gum is essentially a resin, and like many natural resins, its physical state is highly dependent on temperature. In warmer conditions, the tears of mastic gum can become soft and sticky, which can cause them to fuse into a single hard mass, making them difficult to portion and chew. This is a common issue for raw crystals and is particularly problematic for powdered mastic, which is often used in capsules or for culinary purposes. The powdered form lacks the chemical additives that prevent commercial powders from clumping, so even slight heat can cause it to revert to a solid, lumpy state. Conversely, colder temperatures cause the resin to harden, which is a desirable trait for chewing gum that needs to be firm but not brittle. The consistency can be restored with a few hours in the fridge if it gets too soft.
The Direct Benefits of Refrigeration
Refrigeration provides a controlled, cool environment that directly addresses the main vulnerabilities of mastic gum. Storing the gum in the fridge, or in a very cool place below 18°C (64°F), is recommended by manufacturers to prevent softening and sticking. For powdered varieties, this is almost a necessity to prevent the powder from caking into a single lump. By keeping the temperature consistently low, refrigeration also helps to slow down the natural process of oxidation. Oxidation is what causes mastic tears to darken and acquire a yellowish hue over time, and a cooler environment preserves the gum's fresh, clear appearance for longer. While older, more oxidized gum is still safe, its flavor profile may be less pronounced, and its texture can become less ideal.
Optimal Storage Practices for Different Mastic Forms
Different forms of mastic gum—raw tears, powder, and capsules—have slightly different storage needs, but the core principles remain the same: cool, dry, and dark. For raw tears and capsules, keeping them in an airtight container or their original packaging is crucial for preventing exposure to moisture and light. Powdered mastic gum is the most sensitive and benefits most from refrigeration, especially if you live in a warm or humid climate. To prevent clumping, some users find success by shaking the container of powdered mastic occasionally.
Comparison Table: Refrigerated vs. Room Temperature Storage
| Feature | Refrigerated Storage | Cool, Dry, Room Temperature Storage |
|---|---|---|
| Temperature Range | 5°C to 14°C (41°F to 57°F) is ideal for long-term storage. | Up to 18°C (64°F) is acceptable for short-term, but heat can still be an issue. |
| Prevents Clumping | Highly effective, especially for sensitive powdered mastic and softer tears. | Less effective; high temperatures and humidity can cause clumping and sticking. |
| Preserves Freshness | Extends the freshness of the gum and slows oxidation, which can alter color and texture. | Mastic still stays fresh, but oxidation can occur more quickly, especially if exposed to light or heat. |
| Texture for Chewing | Hardens the gum, which can be preferable for a firmer chew. Can be softened slightly by warming it in your mouth before chewing. | Can soften over time, reducing its chewiness. Can become sticky and difficult to chew. |
| Best For | Long-term storage, high-humidity environments, and storing mastic powder. | Short-term storage in temperate climates. |
What if Your Mastic Gum Clumps? How to Fix It
If you find that your mastic gum has softened and clumped, don't worry—it has not lost its beneficial properties. A simple solution involves using cold temperatures to your advantage. For clumped powder or tears that have stuck together, place the entire container in the freezer for a couple of hours. Once frozen solid, the pieces can be broken apart easily. For smaller pieces or powder, a quick pulse in a blender or a few taps on the container can help restore the original texture.

Conclusion: The Best Practice
In conclusion, while mastic gum doesn't strictly require refrigeration to remain safe, it is a highly recommended practice, especially for long-term storage or in warm climates. Refrigerating your gum, particularly the powdered variety, is the best way to prevent clumping, preserve its texture, and maintain its fresh, appealing color and flavor for as long as possible. By keeping your mastic gum in a cool, dry, and dark place—and in the fridge during the summer—you ensure that you get the most out of this unique and ancient product.
