Definitions

  • the present invention pertains to a method for preserving plants or parts thereof, including flowers, through vacuum impregnation in a preservative solution.
  • the present invention relates to a method for preserving plants or parts thereof, including flowers, using vacuum impregnation in a preservative solution.
  • the method comprises: arranging the biological object in a preservative impregnation solution, wherein the entire biological object is immersed in the impregnation solution, and applying vacuum impregnation to the entire object (plant or part of the plant) immersed in the preservative solution, to initiate the vacuum impregnation preservation process.
  • the present invention provides a method that fully preserves a plant or part of a plant or flower by immersing it entirely in a preserving solution, so as to ensure homogeneous penetration of the solution into all tissues.
  • vacuum impregnation treatment with a preservative solution for the plant or part of the plant or flower is a robust method, resulting in complete tissue death to preserve and halt the biological living processes. Following the process, the plant or part of the plant or flower is no longer alive.
  • vacuum impregnation exhibits a homogeneous pattern within the plant or part of the plant that has been treated with a preservative solution. Any differences observed stem solely from the natural variation in the plant's color prior to treatment. Description of a Specific Embodiment of the invention ;
  • the operational parameters are one of the main innovations of the present invention, the method involves a Vacuum impregnation process with a minimum pressure range of 10-400 mbar.
  • the process for fully impregnating the plant with a preserving solution needs to be at least 25 min, but depending on the volume of the preserving pot, can last 120 minutes.
  • the process is considered finalized, when most of the air has been evacuated from the impregnation solution and small or just a minimum amount of bubbles emerge from the solution.
  • the new method involved a full plant preservation with vacuum impregnation.
  • the protocol used was as follows: a pressure falling time of 25 minutes, followed by a holding time of 15 minutes (until most of the bubbling stopped), and then a 5 -minute rising time to atmospheric pressure.
  • the minimum vacuum holding was at 10 mbar 40% glycerol solution was used as a preservative solution.
  • the preservative solution comprises 40% food-grade glycerine, 3.5 g/L tartrazine, 0.55 g/L Blue patent, 1 mL/L Tween 20, and 3 g/L of antioxidant Ascorbic acid.
  • the solution was maintained at 50 degrees Celsius.To run the test, 9 full plants were preserved with vacuum impregnation and a control group with the same number of plants was left untreated.
  • Plants were received fresh, and all of them were processed at the same time in the same room conditions.
  • Control and treated plants were weighed everyday in order to evaluate the weight lost due dehydration in room conditions (40-60% HR), 20-30 degrees of Celsius.
  • the test finalizes when there is no weight lost from the plants treated, normally 7-12 days after the test.
  • a preserved plant must keep a natural looking color and homogenic structure after
  • control plants will lose their weight faster than treated plants, as with the color.
  • Preserved plants will lose their weight even below original weight, and must maintain a shape of a natural looking plant.
  • the protocol used was as follows: a pressure falling time of 25 min; holding time of 15min; (most of the bubbling stops); and then 5 min of rising time to atmospheric pressure.
  • the minimum vacuum holding was at 10 mbar.
  • 40% solution of glycerol was used as a preservative solution.
  • the preservative solution contains 40% food-grade glycerine, 3.5 g/L tartrazine, 0.55 g/L Blue patent, 1 mL/L Tween 20, and 3 g/L of antioxidant Ascorbic acid.
  • Bunches of asparagus stems were received fresh, and all of them were processed at the same time in the same room conditions.
  • the stems were suspended on a rack, and their weights were recorded daily.
  • the same process was applied, plants were suspended for the same time as the treated ones.
  • Control and treated plants were weighed daily in order to evaluate the weight lost due to dehydration in room conditions (40-60% HR), 20-30 degrees Celsius.
  • a preserved stem must keep a natural looking color and homogenic after Vacuum preservation.

Abstract

Un procédé de traitement d'un objet biologique, lequel peut être une plante complète ou une partie d'une plante telle que le feuillage, les plumes ou les fleurs, est décrit. Le procédé consiste à agencer l'objet biologique dans une solution d'imprégnation de conservateur, l'ensemble de l'objet biologique étant immergé dans la solution d'imprégnation, et appliquer une imprégnation sous vide sur l'ensemble de l'objet immergé dans la solution de conservateur pour initier le processus de conservation par imprégnation sous vide.
