Mooncake Freshness Guardian: Externally Controlled Alcohol Preservation Card

The ultimate flavor of a mooncake starts with craft baking and endures with fresh texture—and the secret to this freshness lies in an unassuming externally controlled alcohol preservation card.

Taking food-grade safe paper as its carrier, it’s impregnated with food-grade alcohol. Though compact, it hides “freshness-preserving black technology.” Unlike traditional oxygen absorbers that only target aerobic bacteria, it delivers dual protection: forming a close-fitting shield through contact sterilization while covering every detail with gentle fumigation, comprehensively inhibiting the growth of both anaerobic and aerobic bacteria, and safeguarding the mooncake’s soft texture and pure aroma at the source. What’s more, it won’t cause the mooncake packaging to collapse or wrinkle, perfectly fitting exquisite gift box scenarios. Unaffected by the filling’s pH value or the packaging’s oxygen permeability, it boasts exceptional stability and a cost-performance ratio far exceeding conventional preservation solutions.

While it can’t fully avoid the common issue of oil oxidation in mooncakes, it precisely addresses core freshness needs based on the mooncake’s short consumption cycle. The mild alcohol scent blends naturally with traditional fillings like lotus seed paste, red bean paste, and five-nut, without compromising the silky texture of lava fillings or the refreshing taste of snow skin mooncakes—ensuring every bite retains the pure flavor of just-baked perfection.

A tiny card holds great peace of mind. The externally controlled alcohol preservation card uses safe and efficient freshness-preserving power to keep mooncakes fresh and fragrant at all times, guarding the taste surprise of every reunion moment.
