Embodiment 1

[0040] Example 1 Preparation of electrogenerated functional water suitable for citrus preservation

[0041] Use the Ionian JP-107 electrolyzed water machine, add a sodium chloride solution with a concentration of 0.15% to the water inlet, turn on the switch of the electrolyzed water machine, let it drain the waste water inside the machine, and measure the pH of the acidic water flowing out When the value is 2.4-2.6, the oxidation-reduction potential ORP is 1080-1120mV, and the available chlorine concentration is 30-40mg / L, the acidic electrogenerated functional water obtained is collected in a closed container.

Embodiment 2

[0042] Example 2 Preparation of electrogenerated functional water suitable for citrus preservation

[0043] Use the Ionian JP-107 electrolyzed water machine, add 0.2% sodium chloride solution to the water inlet, turn on the switch of the electrolyzed water machine, let it drain the waste water inside the machine, and measure the pH of the acidic water flowing out When the value is 2.4-2.6, the oxidation-reduction potential ORP is 1080-1120mV, and the available chlorine concentration is 30-40mg / L, the acidic electrogenerated functional water obtained is collected in a closed container.

Embodiment 3

[0044] Example 3 Method for fresh-keeping treatment of citrus with electric functional water suitable for citrus fresh-keeping

[0045] The method of using the electrogenerated functional water prepared in Example 1 or 2 to preserve the freshness of citrus is: (1) first rinse the fresh citrus with clear water; (2) soak it in the electrogenerated functional water prepared in Example 1 for 30 minutes; ( 3) Drain the electro-generated functional water and pack it into boxes for storage.

Abstract

The invention discloses electrolyzed functional water for preserving freshness of oranges and a method for preserving freshness of oranges by using the same. The pH value of the electrolyzed functional water is 2.4-2.6, the oxidation-reduction potential (ORP) is 1080-1120 mV, and the active chlorine concentration is 30-40 mg/L. A preparation method of the electrolyzed functional water comprises the following steps: adding a 0.15-0.2% sodium chloride solution into a water inlet end of an Ionia JP-107 water electrolysis machine, turning on a switch of the water electrolysis machine, draining off waste water in the machine, and collecting with a closed container when determining that the pH value of the effluent acidic water is 2.4-2.6, the ORP is 1080-1120 mV, and the active chlorine concentration is 30-40 mg/L. The method for preserving freshness of oranges by using the electrolyzed functional water comprises the following steps: thoroughly rinsing fresh oranges with clear water, soaking with the electrolyzed functional water for preserving freshness of oranges for 30 minutes, then draining, boxing, and conventionally storing. After the oranges are treated with the electrolyzed functional water, better storage and freshness preservation effect can be achieved.

Description

Technical field [0001] The invention involves the application of electro -functional water on the freshness of the fruit, which specifically involves an electro -functional water suitable for citrus fresh -keeping and its fresh -keeping method for citrus. Background technique [0002] Electric functional water, also known as electrolytic ion water, is a functional water that has great significance to human health.The production process of electrolytic water generally purifies ordinary tap water first, and then uses positive electrodes to disperse, becomes smaller, and re -arranges under the influence of electric fields to make part of the oxidation and reducing potential (ORP) of some of the water.The other part of the water ORP was negative potential, and finally obtained ionic water (acidic electrolyte) and negative ion water (alkaline electrolytic water) through the membrane separation technology.The pH value of acid ion water is generally below 3, with a positive potential, h...
