Problems solved by technology

[0002] Many fruits and vegetables are easy to germinate in the later stage of storage, such as potatoes, onions, garlic, chestnuts, etc., causing great losses
Among them, the storage temperature of potatoes is relatively high, and it is very easy to germinate in the late storage period, which not only reduces the commodity value, but also produces a large amount of toxins, resulting in a large amount of losses.
The active ingredient of the sprout inhibitor currently used in production is imported chlorphenamine (CIPC), which is used for potato storage, but the price is high, and excessive use is harmful to human health and causes environmental pollution

preparation example Construction

[0034] The preparation method of the citronella essential oil is steam distillation or supercritical carbon dioxide extraction, and the supercritical carbon dioxide extraction conditions are a temperature of 40-50°C and a pressure of 10-30Mpa.

[0035] The preparation method of citronella essential oil sprout inhibitor is: (1) direct application of citronella quintessence oil; Fatty acid 5% to 10%. The preparation method is as follows: first fully mix and stir 5% to 10% of citronella essential oil and 80% to 85% of beta-cyclodextrin in a closed container, then add 5% to 10% of stearic acid, and mix and stir Sealed for later use. (3) Emulsion, its formula: 5%~10% of citronella essential oil, 5%~10% of Tween, 5% of ethanol, water, bottling for subsequent use after homogeneous stirring.

[0036] The method of applying this citronella essential oil sprout inhibitor to potatoes: After the potatoes are harvested, pick out diseased and residual potatoes, and put them into storage p...

Embodiment 1

[0037] Example 1: Direct use

[0038] Add citronella essential oil into an open container, put it into the storage environment, the effective concentration is 0.01-0.1mL / L space, and then close the storage place, or cover the potato unit stack (shelf) with sealing materials, such as plastic film, etc. , to prevent the concentration in the environment from being too low. Observe regularly.

Embodiment 2

[0039] Embodiment 2: powder dosage form

[0040] Take 10mL of citronella essential oil, add 80g of β-cyclodextrin, add into a sealed mixer, fully mix and stir for 10 minutes, then add 10g of 5% to 10% stearic acid, mix and stir for 5 minutes, and then seal and store.

[0041] When stacking in layers, directly sprinkle the powder evenly into the potato pile with an amount of 1g in 1L of space.

Abstract

The invention relates to a citronella essential oil sprout inhibitor and application thereof to potato preservation, and discloses the citronella essential oil serving as a novel sprout inhibitor and the application thereof to the suppression of sprouting during potato preservation. The citronella essential oil is applied to the potato preservation environment by methods such as fumigating, spraying and the like, wherein the concentration of the essential oil is controlled to be in a range from 0.01 to 0.1mL/L through direct fumigating during fumigation; and spraying or dipping is adopted during liquid processing so as to control the concentration to be 0.1 to 1 percent. By using the citronella essential oil originated from a natural plant as an active ingredient, the sprouting during the potato preservation can be effectively suppressed, chemical substances are reduced or avoided, and the sprout inhibitor has the advantages of good sprout inhibition effect and environmental friendliness.

Description

technical field [0001] The invention belongs to fresh agricultural product fresh-keeping products, technology and application, and relates to a citronella essential oil bud inhibitor and its application in potato storage and fresh-keeping. Background technique [0002] Many fruits and vegetables are easy to germinate in the late storage period, such as potatoes, onions, garlic, chestnuts, etc., causing great losses. Among them, the storage temperature of potatoes is relatively high, and it is very easy to germinate in the late storage period, which not only reduces the commodity value, but also produces a large amount of toxins, resulting in a large amount of losses. The active ingredient of the sprout suppressant currently used in production is imported chlorphenamine (CIPC), which is used for potato storage, but the price is high, and excessive use is harmful to human health and causes environmental pollution. Contents of the invention [0003] The purpose of the presen...
