Embodiment 1

[0020] Put 20 kg of harvested fresh flowers into a food vacuum packaging bag with a weight of 1 kg per bag, pump the vacuum until the vacuum degree in the packaging bag reaches -0.05MPa, seal it, and immediately put it into a quick-freezing cabinet at -50°C After quick freezing for 2 hours, transfer to a freezer at -20°C and store for one year. The color and smell of osmanthus flowers after Kaifeng and thawing are basically the same as that of fresh flowers.

Embodiment 2

[0022] Put 20 kg of harvested fresh flowers into food vacuum packaging bags with a weight of 2 kg per bag, pump the vacuum until the vacuum degree in the packaging bag reaches -0.095MPa, seal it, and immediately put it into a quick-freezing cabinet at -30°C After quick freezing for 2 hours, transfer to a refrigerator at 0°C and store for one year. The color and smell of osmanthus flowers after Kaifeng and thawing are basically the same as that of fresh flowers.
