The invention relates to an ultrasonic
permeation enhancing preparation method for a preserved fresh flower and a preserved fresh flower and belongs to the technical field of flowering
branch chemicalpreservation. The ultrasonic
permeation enhancing preparation method for the preserved fresh flower comprises the following steps of conducting decolorizing treatment on a fresh
cut flower, then immersing the fresh
cut flower into a
liquid phase substitute for ultrasonic treatment, and
drying. According to the ultrasonic
permeation enhancing preparation method for the preserved fresh flower, thethermal motion of substitute molecules and water molecules can be quickened by the
cavitation effect and
heat effect of ultrasonic, therefore the
disadvantage can be overcome that the power of insideand outside
diffusion of the
moisture in the flower when replacement is conducted in the normal condition; meanwhile, micro channels are formed on the surface of
petal tissues and macromolecules in the
liquid phase substitute is promoted to permeate into the micro channels for
moisture replacement, so that the shrinking degree of the petals is effectively reduced; moreover, all the components in the
liquid phase substitute is uniformly distributed in
cell tissues, so that the overall preserved fresh flower is uniformly dyed, the flexibility of the petals is good, the preserved fresh flower ismoist, soft and good in
soundness and the appearance form of the fresh
cut flower is largely kept.
