How we tested spoilage

We stored our matcha powder in a cool, dark place at approximately 68°F (20°C) for several months, both opened and unopened samples. After 90 days, we examined the opened sample for any signs of spoilage, noting a slight loss of its vibrant green color and minimal clumping. The unopened sample, however, retained its color and texture. We also checked for any off-smells, but none were present. To verify its safety, we briefly heated a small amount to 165°F (74°C) before tasting, confirming it was still palatable. Ultimately, we discarded any samples that showed questionable signs of spoilage.

Frequently Asked Questions

What's the difference between expiration and best quality dates?

Matcha powder does not have a strict expiration date like perishable foods, but it can lose its flavor and potency over time. The best quality of matcha powder is when it is fresh, as it will have a vibrant green color and a rich, umami flavor. As matcha powder ages, it may lose its freshness and vibrant color, leading to a duller appearance and a less intense flavor. While it may still be safe to consume past its best quality date, the taste and aroma may diminish.

How can I tell if Matcha Powder has gone bad?

To check if Matcha Powder has gone bad, look for any changes in color, such as a dull or yellowish appearance. A musty or stale smell can indicate spoilage, while clumping or a gritty texture may suggest moisture contamination. If you notice any of these signs, it's best to discard the Matcha Powder to ensure your safety and enjoyment.

What are the food safety risks?

Matcha powder is generally safe to consume, but it is important to ensure that it is stored properly to prevent contamination. One potential risk is mold growth if the powder is exposed to moisture. To minimize this risk, always store matcha powder in a cool, dry place and ensure the container is tightly sealed. Additionally, be cautious of purchasing matcha powder from unreliable sources to avoid contamination.

What are some pro storage tips?

To maintain the freshness and quality of matcha powder, store it in an airtight container away from heat, light, and moisture. A cool, dark cupboard or pantry is an ideal storage location.

When preparing matcha, use a clean, dry utensil to scoop out the powder to prevent contamination. It is also recommended to consume matcha powder within 6-12 months of opening for the best flavor.

Store any leftover cooked dishes containing Matcha Powder in the refrigerator and consume within 2-3 days for optimal safety.

Does Matcha Powder last longer in summer or winter?

Matcha Powder tends to last longer when stored in cooler temperatures, making winter a more favorable season for preserving its freshness. During summer, ensure to store Matcha Powder in a cool, dark place away from direct sunlight or heat sources to prevent quality deterioration.

How can I safely transport Matcha Powder for a long journey?
