Problems solved by technology

However, some existing fresh-keeping methods have certain limitations in the application environment of the measures and in environmental protection. The extract is rich in phytic acid, which can enhance the antioxidant capacity of cut flowers, reduce the respiratory metabolism of cut flowers, and delay their aging process. The consumption of energy substances in the body, the strong chelating property of phytic acid enables it to chelate with the metal ions in the coenzymes of cut flowers to inhibit or slow down the occurrence and progress of enzymatic reactions, thereby prolonging the life of fresh cut flowers, but the preservation effect of different concentrations is also different. It will be different, so it is necessary to choose the appropriate extraction method and the appropriate concentration of natural plant extracts to be the most conducive to the preservation of fresh cut flowers, and the price is cheap, the content of chemical components is small, it is harmless to the human body, non-toxic and non-polluting to the environment

Embodiment 1

[0022] The present invention provides a kind of manufacturing craft recipe of the carnation cut flower fresh-keeping reagent of ginkgo extract, and test method is as follows:

[0023] Step 1: Ginkgo pretreatment, after the ginkgo leaves are collected, lay flat, place in a cool place to dry naturally, adjust the drying oven to 35-40°C, bake for 12 hours, crush the materials with a powder machine, pass through a 20-mesh sieve, and pack them separately Put into a ziplock bag and store at 4°C for later use;

[0024] Step 2: Ginkgo biloba ethanol extract is prepared, using three dipping extraction methods, the specific operations are as follows:

[0025] The first time: Weigh 50g of the pulverized functional plant ginkgo sample, add quantitative 95% ethanol, the standard is to soak the ginkgo sample for more than 4cm according to the sample volume, soak, put it in a shaker and shake for 48h. Filter to obtain filtrate and residue;

[0026] The second time: add an appropriate amoun...

Embodiment 2

[0034] The invention provides a preparation method of the carnation cut flower fresh-keeping reagent of ginkgo extract, and the configuration method is as follows:

[0035]Step 1: Ginkgo pretreatment, after the ginkgo leaves are collected, lay flat, place in a cool place to dry naturally, adjust the drying oven to 35-40°C, bake for 12 hours, crush the materials with a powder machine, pass through a 20-mesh sieve, and pack them separately Put into a ziplock bag and store at 4°C for later use;

[0036] Step 2: Preparation of ginkgo water extract, take 20g of the crushed sample of the functional plant ginkgo and put it into a 1000ml large beaker, then add 1000ml of distilled water, put it in a warm water bath at 50°C for 12h, boil for 30min, cool, and take a conical bottle, glass funnel, glass rod, and filter paper, which are combined into a simple filter device, and the upper turbid liquid in the solution to be filtered after cooling is filtered by means of the drainage of the g...

Abstract

The invention discloses a manufacturing process for a carnation cut flower freshness-keeping reagent of a ginkgo extracted liquid. The manufacturing process comprises the following steps: preparing aginkgo extracted liquid, preparing a ginkgo ethanol extraction liquid, putting the ginkgo ethanol extraction liquid into a vase, wherein the total vase solution is 300mL, preparing a solution with a ginkgo ethanol extraction liquid concentration of 5.0mL/L by mixing the ginkgo ethanol extracted liquid and water, wherein 1L of the solution contains 5.0mL of the ginkgo ethanol extraction liquid, andplacing 3% of sucrose into the vase. According to the invention, the vase solution with the ginkgo ethanol extraction liquid concentration of 5.0mL/L can effectively delay aging of carnation cut flowers, prolongs the vase flower life, and has best freshness keeping effects; the vase solution with the ethanol extraction liquid concentration of 5.0mL/L has relatively smooth and uniform changes of TDS, conductivity and salinity in determination of various physiological indexes; carnations treated by the vase solution with the ethanol extraction liquid concentration of 5.0mL/L have relatively stable POD activity, and the vase solution has best freshness keeping effects; and the reagent has the characteristics of having a low price, a less content of chemical components and no pollution to environments, and being harmless to human bodies, non-toxic, and environmentally friendly.

Description

technical field [0001] The invention relates to a fresh-keeping reagent for cut flowers, in particular to a preparation process of the fresh-keeping reagent for carnation cut flowers with ginkgo extract. Background technique [0002] Carnation, also known as carnation, also known as carnation, carnation, carnation, carnation, carnation, is a plant of the family Caryophyllaceae and the genus Carnation. It is generally distributed in the temperate zone of Europe and Fujian, Hubei and other places in mainland China. It is native to the Mediterranean region. It is one of the most widely used flowers in the world. Carnation, which includes many varieties and hybrids, blooms almost continuously in the greenhouse. Since 1907, pink carnations have been used as a symbol of Mother's Day, so they are often used as flowers dedicated to mothers today. Carnation is a perennial herb. It is widely cultivated for its fringed petals and fragrant scent. It is generally divided into flower ...
