AI Technical Summary
Existing technologies cannot effectively prevent white preserved flowers that have undergone dehydration and replacement from turning yellow during long-term storage, and commonly used preservatives may damage the structure of the flowers.
Using gardenia extract as a matrix, a protective system with triple functions of anti-oxidation, UV shielding and pH buffering was constructed. Gardenin and total polyphenols were extracted by ultrasound, combined with β-cyclodextrin inclusion and citrate-sodium citrate buffer to form a transparent protective film, and UV irradiation was used to enhance photothermal stability.
It achieves the whiteness of preserved flowers for long-term preservation at room temperature, significantly reduces the yellowing index, and maintains the light and heat stability and structural integrity of the flowers.
