Abstract

A surface active disinfecting, microbicidal and hygienizing aqueous solution containing active oxygen and a bicarbonate of an alkaline metal is employed for washing fruits and vegetables.

Description

AQUEOUS DI SINFECTING SOLUTION
DESCRIPTION
The present invention relates to a surface active
disinfecting, microbicidal and hygienizing aqueous solution.
More particularly, the present invention refers to a
surface active disinfecting, microbicidal and hygienizing
solution, especially useful for washing and disinfecting
foodstuff.
The aqueous solution of the present invention is
particularly useful for use in washing and disinfecting
vegetables and fruits.
As is known, the peel of fruits and raw vegetables, while
having a high contents of vitamins and mineral salts, contains on
the surface many microbes, bacteria and other polluting
substances originating from the fertilizers employed in the
production, as well as from various birds, animals and insects,
atmospheric agents, etc.
In order to eliminate said microbes, bacteria and
polluting substances, fruits and vegetables are submitted to
intense water-washing in the presence of chemical products that
improve water effectiveness and cleaning and disinfecting action. One such product is sodium bicarbonate which, however,
while being useful for washing, has no disinfectant and/or
bactericidal action.
The known art also adds to washing water a product
called "amuchina", which has, however, the drawback of
leaving residues harmful for the human body that are not easily
removable.
On the industrial plane, chlorine or chorine releasing
compounds are employed during washing for disinfecting fruits
and vegetables. However, the use of such compounds requires
an accurate and intense washing to eliminate any traces of
chlorine that, besides having a foul smell, is toxic. For this
reason, chlorine-based products for the domestic washing of
fruits and vegetables or other foodstuff are not available.
Object of this invention is to obviate the above
drawbacks.
More particularly, object of this invention is to provide
an aqueous washing solution that, besides markedly reducing the
bacterial load and the polluting substances from fruits and
vegetables, does not leave any traces of substances that are
noxious or toxic for the body nor impart undesired smells or
tastes to the washed product. A further object of the present invention is to provide an
aqueous washing solution devoid of any contraindication,
innocuous for the human body and such as to allow at the same
time to maintain unaltered the natural organoleptic, nutritive and
fragrance of washed fruits and vegetables.
A further object of the present invention is to provide an
aqueous washing solution for fruits and vegetables that is of
easy and simple use.
According to the present invention, these and still other
objects are obtained by means of a surface active, disinfectant,
microbicidal and hygienizing solution containing active oxygen
and an alkaline metal bicarbonate.
Any compounds able to generate active oxygen in
aqueous solution may be employed. By way of example, we
recall ozone, ozonides, peroxides in general, and in particular
hydrogen peroxide at any concentration, e.g., 1 , 10, 20, 30,
50.90% by weight, chlorides and perchlorides of alkaline metals,
calcium or magnesium, etc.
Alternatively, active oxygen may be obtained by
electrolysis. The concentration of active oxygen in the aqueous
washing solution is not critical for the purposes of the present
invention. It may range between 1 and 99% by weight.
Alkaline or calcium or magnesium chlorates are
preferred for the production of active oxygen in the aqueous
washing solution. The concentration of said chlorides may range
between 1 and 99% by weight, preferably between 5 and 30% by
weight, based on the weight of the solution.
Among the alkaline metal bicarbonates, sodium and
potassium bicarbonates are preferred for economic reasons. The
concentration of bicarbonate may range between 1 and 8%,
preferably between 3 and 5% by weight based on the weight of
the solution.
Besides the aforesaid compounds, the aqueous solution
of the present invention may contain natural extracts of
alimentary plants that reinforce the bactericidal action of the
solution. Examples of natural extracts that can be used comprise
extracts of almond, laurel, sage, basil, mint, pine, lemon, etc.
The concentration of the extract in the solution is not
critical and may vary between 0.001 and 10% by weight. The disinfecting, microbicidal and hygienizing aqueous
solution of the present invention is used such as is, by spraying
it on the surface of fruits and vegetables.
The treatment process of fruits and vegetables with the
solution of the present invention comprises the following steps:
application of such solution on the product to be treated, leaving
the solution in touch with the product for a period of time
comprised between 1 and 5 minutes, and afterwards water-
washing the product. The so washed product may be eaten.
The application of the solution of the present invention
on the product to be treated my be performed by spraying,
atomization or sprinkling. Measurements carried out by the
applicant on the rinsing waters of the product treated with the
solution of the present invention have determined that the
bacterial load is lower by at least 5 times the one allowed for
fourth range foodstuff, and by 100 to 1000 times the one present
in the washing waters of the same untreated product.
From what has been expounded hereinabove, the
advantages achieved by washes with the solution of the present
invention are evident.
Such solution, in fact, besides being very effective to
remove and reduce bacteria, microbes and polluting substances harmful for the body, is not toxic and does not contains chemical
products harmful or noxious for health, has no smell besides the
one left by the natural extract of alimentary plants (if any), does
not leave any traces of tastes or smells, is biodegradable without
leaving harmful residues, keep the natural fragrance of the
product treated unaltered and, mainly, may be applied in a
simple manner by spray.
Because of such properties, the solution of the present
invention is particularly suitable for washing fruits and
vegetables intended for the ill, especially those affected by
SIDA.
A further advantage of the solution of the present
invention lies in that it allows to markedly reduce the amount
necessary to perform a full bath of the product. So, for instance,
300 ml of disinfecting solution of the present invention proved
sufficient to clean and disinfect the amount of fruits and
vegetables eaten by a person in two months.
The solution of the present invention has been described
above with reference to fruit and vegetable washing; however,
the same solution may be applied for a different use and in
general for all the applications of sanitization or disinfection of
products.
