[0030] Further, the pomelo peel flavone extract is prepared by the following method:

[0031] 1) Cut pomelo peel into cubes, add 50-60% ethanol with a volume concentration of 1:10-15 according to the material-to-liquid ratio, stir evenly, reflux and extract in a water bath at a temperature of 70-85 ℃ for 50-60 min to obtain an extract. The extract is filtered to obtain an extract;

[0032] Wherein, the material-to-liquid ratio 1:10-15 means that 10-15 mL of ethanol is added to every g of diced pomelo peel;

[0033] 2) Centrifuge the above extract at 3000-4000 r / min for 30-40 min, take the supernatant, and vacuum concentrate the supernatant to remove ethanol to a primary concentrate with a solid content of 20-30%;

[0034] 3) The above-mentioned primary concentrated liquid is allowed to stand for crystallization at a temperature of 4 ℃, and then centrifuged at 10000-15000 r / min at a temperature of 0 ℃, and the supernatant is discarded to obtain crystals;

Abstract

The invention discloses a multifunctional fresh cut flower gel preservative and a using method thereof. The multifunctional fresh cut flower gel preservative is formed by mixing the following components according to a certain weight ratio: carbomer, sucrose powder, 8-hydroxyquinoline, 6-benayl aminopurine, a pomelo peel flavone extract, aluminum sulfate and pigments. The using method comprises the following steps: spreading a gel preservative into water, naturally swelling the carbomer for 12-24 hours, dripping triethanolamine, so that the solution is in a gel shape, and directly inserting the fresh cut flowers, thereby obtaining the product. According to the multifunctional fresh cut flower gel preservative disclosed by the invention, the bottling service life of the fresh cut flowers can be prolonged, the gel can support cut-flower arrangement, the defects that the liquid preservative is easy to evaporate and is easily turbid and water easily leaches after being knocked over are overcome, and the ornamental value of a glass vase is increased by virtue of the bright-colored and porous appearance, so that the indoor cut flowers are relatively fresh and bright.

Description

Technical field [0001] The invention relates to the field of cut flower preservation, in particular to a multifunctional fresh cut flower gel preservation agent and a use method thereof. Background technique [0002] The freshness of cut flowers is an important indicator of the quality of cut flowers. Cut flowers are still living organisms after being cut, undergoing a series of complex metabolic processes and physiological changes, which affect the ornamental value and life span of cut flowers. [0003] After the cut flowers leave the plant's parent body, the water and carbohydrates needed in the physiological metabolism process are cut off, coupled with environmental changes, mechanical damage at the incision and microbial invasion, etc., easily lead to metabolic disorders, making the cut flowers more than staying The mother plant senescence and spoilage faster. The quality of cut flowers is a common concern of flower producers, operators, and consumers. It is of great signific...
