Embodiment Construction

[0010] The method for a kind of piperine ethanol-water solution fresh-keeping cowpea provided by the invention, the specific embodiment is:

[0011] 1) Ethanol-water mixture: fully mix ethanol and water according to the volume ratio of 10%~60%;

[0012] 2) Piperine ethanol-water solution: Dissolve piperine in the ethanol-water mixture prepared in step 1) according to the mass ratio of 0.01% to 1.0%;

[0013] 3) Preservation of cowpea: Soak fresh cowpea in the ethanol-water solution of piperine prepared in step 2) for 1-10 minutes, take it out and dry it.

[0014] The ethanol-water mixture is used to dissolve piperine and soak vegetables so that the piperine can evenly cover the surface of the cowpea, and the ethanol-water mixture is easy to dry, has no adverse effects on the human body, and has no residue after drying.

[0015] The implementation of the present invention will be described below with specific examples.

[0016] Prepare ethanol-water mixed solution acc...

Abstract

Provided is a method for refreshing cowpeas by using piperine ethanol-water solution. Piperine is dissolved in ethanol-water mixed solution according to a certain proportion to prepare the ethanol-water solution containing the piperine with certain concentration, the cowpeas are soaked in the solution for a period of time and then fetched out to be dried, and refreshing time can be prolonged for more than two days effectively.

Description

technical field [0001] The invention relates to the fresh-keeping technology of cowpea, uses natural extract piperine, and is a method for keeping fresh cowpea with piperine ethanol-water solution. Background technique [0002] The "Hainan Poisoned Cowpea" incident that occurred in March 2010 once again highlighted the importance of green preservation in the process of storage and transportation of fruits and vegetables. At present, the domestic vegetable preservation technology is mainly cold storage combined with chemical fungicide treatment, but because chemical fungicide residues are harmful to human health and plant pathogens are resistant to chemical fungicides, there is an urgent need to study pollution-free and efficient antiseptic preservative products and technologies. [0003] Piperine (piperine) is the main active chemical substance in pepper, which belongs to the cinnamon phthaloamide alkaloid[9], and is widely found in nature, especially in the piperaceae p...
