We started working with Vitec Global on the Aspida brand of Organic Sanitiser and Disinfectant in early 2018, over the following 11 months we carried out a lot of trials into just what Aspida could offer to the agricultural industry. Miracle Tech also used a contact in the UAE to help Vitec set up a massive trail on a large dairy farm, bacteria grow 4x quicker in the heat they experience so this research has helped us tremendously. Aspida is now proven to be a really effective sanitiser and disinfectant for use in the agricultural industry, especially the livestock sector. It can be used by dairy, beef, sheep, pig and poultry farmers to name a few and is completely safe to both humans and animals. 

It is produced from the electrochemical reaction of water, sodium chloride (salt) and electricity. The applications for this technology include any process requiring sterilization, disinfecting and cleaning or water purification.

The primary component of ASPIDA is hypochlorous acid (HCIO).

ASPIDA is a pH neutral disinfectant generated by the electrolysis of a diluted sodium chloride (NaCl) solution passing through an electrolytic membrane.

This process creates large volumes of a gentle, but extremely potent antibacterial solution capable of rapidly eliminating bacteria, viruses, spores, cysts, scale and bio-film. 

The general product specification of ASPIDA is:

• pH 6.5 –7.5, (can be adjusted)
• Oxidation-Reduction Potential (ORP) > +800m – 1000 mV
• EC 5-15ppm (varies with the amount of free available chlorine) • Free Available Chlorine (FAC) 50-500 ppm, (can be adjusted)

 ASPIDA is an Electro-Chemical Activation Solutions (ECAS)

The Electro Chemical Activation of water involves the exposure of water and the natural salts therein or added to it, to a substantial electrical potential difference. If an anode (+) and a cathode (-) is placed in pure water and a direct current is applied, electrolysis of water occurs at the poles, leading to the breakdown of water into its constituent elements.

If sodium chloride (NaCl) or table salt is used as a solution, the dominant electrolysed end product is hypochlorite; a chlorine based reagent, which is commonly used to treat water to kill microorganisms.

The ECA process is based on the latter reaction; however, the key innovation is the interposition of an ion-permeable membrane between the positive and negative electrodes as well as the design and materials used for the electrodes. The electrochemical reactor module makes use of two, insulated rhodium plated, titanium electrodes. The base solution used in this reactor is a weak solution of NaCl, which is split into two channels, one running through the anode (+) chamber and the other through the cathode (-) chamber.

What does it do?

It acts as a disinfectant, which contains a cocktail of natural bactericides, such as Free Chlorine, Oxygen, and certain hydroxyl radicals including CL* and OH*. These form a greater bactericidal solution (up to 5 times in strength) than an equivalent amount of chlorine or sodium hypochlorite. The solution is meta-stable.

What is ORP?

ORP stands for Oxidation-Reduction Potential. ORP is a measure of ASPIDA’s ability to break down contaminants. ORP has a range of –2,000 to + 2,000 and units are in “mV” (millivolts). Since ASPIDA is an oxidizer, we are only concerned with positive ORP levels (above 0 mV).

ORP sensors work by measuring the dissolved oxygen. More contaminants result in less dissolved oxygen because the organics are consuming the oxygen and the ORP level will be lower. The higher the ORP level, the more ability the solution has to destroy contaminants.

As an example, drinking water is adequately disinfected at an ORP of +650 mV

ASPIDA is composed of the oxidizing agents Hypochlorous Acid (HCIO) and Sodium Hypochlorite (CIO). The bactericidal action of ASPIDA is due to the combination of these substances. They are bactericidal because certain bacterial cell components can react readily with them, having a higher oxidation potential than most other chemicals.

The mechanism of action for the eradication of various microorganisms by ASPIDA is well documented by third party resources.

The mode of action is as follows:

·       The free ions in ASPIDA rapidly react and denature proteins.

·       Once ASPIDA encounters a microorganism; it attacks the bacterial proteins located in the cell membranes.     

·       Because of the osmolality difference (the concentration of ions in the solution versus in the cytoplasm), ASPIDA induces the rupture of cell membranes, leading to cell lysis.

·       The high oxidation of ASPIDA first damages bacteria cell walls, allowing infiltration by water.The microbe reaches capacity, causing an osmotic, or hydration, overload. The acidic fluid and water floods the cell faster than the cell can expel it, literally causing the cell to burst.

Toxicity

No evidence of toxicity in any form has been observed in any testing carried out by independent third parties.

Regulatory

The United States Environmental Protection Agency has given approval (40 CFR 180.1054) for washing raw foods with Electrolysed Water that are to be consumed without processing.

Electrolysed Water is approved under United States Code of Federal Regulations (“CFR”) 21 CFR 173.315 for direct contact with processed foods, and is approved for indirect food contact applications under 21 CFR 172.892, 21 CFR 175.105, 21 CFR 176.170 and 21 CFR 177.2800.

Electrolysed Water is an approved sanitizer that meets 21 CFR 178.1010.
Electrolysed Water is not classified as hazardous in accordance with European Directive 99/45/EC and CLP Classification No 1272/2008
The United States Food and Drug Administration has expressed no concerns and holds no opposition for the use of Electrolysed Water.

The use of Electrolytically Generated Hypochlorous Acid is consistent with FDA’s labelling definition of a processing aid.
