Embodiment 1

[0036] The use of polyamine decomposition inhibitors aminoguanidine in grape preservation, the specific steps are as follows:

[0037] (1) Avithene 20 mm was added to a 0.45 mm Tween 20 using the aminoguanidine hydrochloride and water.

[0038] (2) At the beginning of the grape, the solution prepared by step (1) was sprayed once every 5 days, and sprayed 3 times. It is necessary to spray in the morning or evening, do not spray in rainy days.

Embodiment 2

[0040] The use of the use of polyamine decomposition inhibitors in pomegranate preservation, the specific steps are as follows:

[0041] (1) Avithene 20.5 mm of Tween 20 was added using the aminoguanidine hydrochloride and water.

[0042] (2) When the pomegranate color is started, the solution prepared by step (1) is sprayed once every 6 days, and it is sprayed 4 times. It is necessary to spray in the morning or evening, do not spray in rainy days.

Embodiment 3

[0044] The use of polyamine decomposition inhibitors aminoguanidine in apple preservation, the specific steps are as follows:

[0045] (1) Aqueous aminoguanidine hydrochloride solution having a concentration of 7 mm was added to a hydrochloride solution of 7 mm, and 0.55 mm of Tween 20 was added;

[0046] (2) When the apple is shot, the solution prepared by step (1) is sprayed every 7 days, and the co-spray 3 times. It is necessary to spray in the morning, do not spray in the rain.

Abstract

The invention discloses the application of polyamine decomposition inhibitor aminoguanidine in fruit preservation, and the application of polyamine decomposition inhibitor aminoguanidine in fruit preservation. Fruits are peaches, apples, grapes, pomegranates, apricots or strawberries. For example, the above-mentioned method of using the polyamine decomposition inhibitor aminoguanidine in fruit preservation, the specific steps are as follows: (1) using aminoguanidine hydrochloride and water to prepare an aqueous solution of aminoguanidine hydrochloride with a concentration of 1 mM-10 mM; ( 2) Spray the aminoguanidine hydrochloride aqueous solution in step (1) at the beginning of fruit color change. The spraying method is to use the solution prepared in step (1) to spray once every 4-7 days, and spray 3- 5 times. The invention inhibits the catabolism of polyamines in the process of fruit ripening, utilizes the polyamines of the fruit itself to inhibit ethylene synthesis, delays fruit ripening and softening, prolongs storage and preservation time, has good effect, and has low use cost.

Description

Technical field [0001] The present invention belongs to the field of storage and preservation technology in the field, and more particularly to the application of a polyamine decomposition inhibitor aminoguanidine in fruit preservation and use. Background technique [0002] With the improvement of living standards, people's demand for various fruits is more and more strong. However, more kinds of fruits are like peaches, lychees, grapes, cherries, strawberries, etc., but they are very unbelful. It is therefore developing a variety of chemical preservatives for fruit storage preservation. At present, the most common use of ethylene receptor inhibitors (1-MCP) is used in the market. Although 1-MCP is simple and efficient, it is necessary to close space fumigation treatment, and its preservation effect on non-breathing transition fruits is not obvious. [0003] There are currently more research reports of polyamine treatment in fruit storage preservation. Ma Yue Yue et al. Reported ...
