Description

  The present invention relates to an improvement in a method for preventing oxidation of various edible oils. Electrons are imparted to edible oils by generating negative potential fluctuations and electric field fluctuations in conductive electrode plates installed in or near the edible oils. In addition, by changing the physical properties of the edible oil by affecting the electronic state of the atoms and molecules that make up the edible oil, it is possible to not only prevent its oxidation but also improve its thermal conductivity and reduce its viscosity. The present invention relates to a method for preventing oxidation of oil.

Edible oils and the like are generally oxidized by contact with air, and the quality of the oil decreases. Therefore, edible oil and the like are stored in a non-breathable sealed container, and after removing a necessary amount of edible oil, the container is sealed again. However, it is difficult to prevent air from entering the sealed container when the edible oil is taken out, and as a result, the quality of the edible oil stored in the container is promoted by oxidation. .
In addition, there are measures such as the use of air extractors and air absorbents, filling with inert gas, etc. as measures to prevent oxidation of the edible oil stored above, but these are all small-scale factories and general households in terms of equipment costs. It is difficult to adopt easily.

On the other hand, edible oil after use, for example, edible oil after being used to make fried foods in general households, has a relatively rapid oxidation due to high temperature heating, and its quality deteriorates remarkably due to repeated use 2-3 times. And cannot withstand reuse.
In addition, edible oil tends to increase in viscosity when used repeatedly, and as a result, the permeability of the oil during fried food preparation deteriorates, so-called high-quality fried food (so-called “crisp texture”) Fried foods)) cannot be made.

By the way, in order to prevent oxidation and viscosity increase of edible oil in use and to solve the problems as described above due to these, various techniques using a filtration device, an antioxidant and the like have been developed ( JP 2013-81426, JP 9-1000048, etc.).
However, the conventional antioxidants for edible oil of this type are all large and expensive, and cannot be used easily in small-scale enterprises and general households, and provide a sufficient antioxidant effect. There is a difficult point.

  The present invention is intended to solve the above-mentioned problems in the conventional anti-oxidation technology for edible oils, etc., and uses a small-sized equipment with a simple structure, and with a small amount of energy consumption, it is highly efficient and easily edible. Oxidation of oils and increase in viscosity can be prevented, which allows edible oils to be used repeatedly over a long period of time. The main object of the invention is to provide a method for preventing the oxidation of edible oil, which can be made well.

The invention of claim 1 is an AC power supply having an output frequency of 2 Hz to 200 Hz with one output terminal grounded, and an LC parallel circuit having an output frequency of 2 kHz to 2000 kHz connected in series to the other non-grounded output terminal of the AC power supply. A power supply apparatus that outputs a superimposed wave vo of the output voltage v of the AC power supply and the induced electromotive force v ′ induced in the LC parallel circuit by an external electromagnetic wave, with the other end of the LC parallel circuit as an output terminal; A conductor electrode plate connected to the output terminal of the power supply device via a lead wire, housed in a metal container and directly immersed in edible oil, or disposed on the outer surface of the metal container Of the edible oil in the metal container in which the electric field fluctuation is caused by changing the electric potential of the electrode plate made of the conductor by the output voltage of the superimposed wave from the power supply device, and the edible oil is exposed to the changing electric field. In the antioxidant method, the conductive electrode plate is made of a titanium alloy or a conductive electrode plate made of rubber or plastic containing titanium alloy powder, and the other end of the LC parallel circuit and the output terminal of the power supply device Between the output terminal of the power supply device and the ground-side terminal of the AC power supply, and the first rectifying element that blocks the flow of current from the LC parallel circuit side to the conductor electrode plate side. By providing a second rectifying element that blocks current flow from the ground side of the AC power source to the conductive electrode plate side through the lead wire, and by giving a negative potential fluctuation to the conductive electrode plate by the power supply device , Quantum waves are generated by fluctuations in the outer electron orbits of the material atoms that make up the electrode plate made of conductors and proton oscillations based on the fluctuations, and the edible oil is irradiated with the quantum waves and the edible oil is exposed to a fluctuating electric field. about It is an basic configuration of the invention.

According to a second aspect of the present invention, in the first aspect of the invention, the first and second rectifying elements are PN diodes .

The invention of claim 3 is the invention of claim 1, wherein the metal container is a stainless steel container .

  The present invention includes an AC power supply having one output terminal grounded, and a rectifying element having one end connected in series to the non-grounded output terminal side of the AC power supply and preventing current from flowing out from the non-grounded output terminal. Using a power supply device, connecting a conductor electrode plate to the ungrounded output terminal of the power supply device via a lead wire, and immersing the conductor electrode plate directly in an edible in a metal container or An edible material in a metal container is disposed on the outer surface of a metal container containing edible oil, and generates an electric field fluctuation by applying a negative potential fluctuation to the conductor electrode plate by applying the AC power supply. It is designed to prevent oil oxidation.

  That is, by applying the AC power supply of the power supply device, a negative potential fluctuation is applied to the conductive electrode plate, and electrons are supplied from the power supply device to the conductive electrode plate, When the number of electrons increases and a vibration wave in the negative direction is not applied, a part of the electrons disappears due to the discharge, and this causes a potential fluctuation in the negative direction in the conductive electrode plate.

  Further, when the alternating voltage v or the superimposed wave output voltage vo of the alternating voltage v and the induced electromotive force v ′ is applied from the power supply device to the conductive electrode plate, the potential of the conductive electrode plate varies. The electric field on the surface of the conductive electrode plate and the vicinity thereof fluctuate, and the edible oil is exposed to the fluctuating electric field.

  When the electric field fluctuates due to a negative potential fluctuation of the conductive electrode plate, the negative ions of the conductive electrode plate increase, and the outer electron orbit of the atoms of the material constituting the conductive electrode plate fluctuates. Arise. Quantum waves based on proton (plus ion) vibrations are radiated, and the molecules and groups of atoms that make up the edible oil repeat vibrations, reducing intermolecular forces and increasing reducibility. The oil's physical properties such as oxidation resistance, viscosity, and thermal conductivity change.

More specifically, by adding electrons to the edible oil, its reducibility is enhanced, and oxidation of the edible oil is controlled and durability is improved. Therefore, the freshness of edible oil can be kept high over a long period of time.
Moreover, by using the low-frequency alternating voltage v, the viscosity of the edible oil is lowered, the permeability thereof is increased, and a deep-fried food with a good texture can be obtained in a shorter time.

Further, in the case of the superimposed wave output voltage vo of the low frequency AC voltage v and the induced electromotive force v ′ of the LC resonance circuit, the intermolecular force of the oil is reduced by the fluctuating electric field and the thermal conductivity is increased. Deep-fried food can be made even at a low temperature of about 50 ° C.
In addition, a higher antioxidant effect can be achieved by appropriately selecting the basic frequency of the AC power supply and the resonance frequency of the LC resonance circuit according to the type of edible oil.

  As described above, the method for preventing oxidation of edible oil according to the present invention has been confirmed to be highly effective in actual operation tests, and has excellent practical utility.

However, the theoretical analysis on the effect of the method for preventing edible oil oxidation according to the present invention, that is, the effect of preventing the edible oil from being oxidized and viscosity reduction has not been sufficiently performed yet.
Therefore, there are many unclear points regarding the cause and mechanism of the antioxidant effect of the edible oil produced by the present method invention due to electric field fluctuations, etc., but the present invention is actually as described above. It has excellent practical utility.

It is explanatory drawing which shows 1st Embodiment of this invention. It is explanatory drawing which shows 2nd Embodiment of this invention. It is explanatory drawing which shows 3rd Embodiment of this invention. It is explanatory drawing which shows 4th Embodiment of this invention. It is explanatory drawing which shows 5th Embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing a first embodiment of the present invention, and is an explanatory view of a method for performing an antioxidant treatment of edible oil stored in a metal container.

  Referring to FIG. 1, the edible oil oxidation treatment apparatus used in the present invention accommodates a power supply device 1, a conductive electrode plate 4 connected to the power supply device 1 through lead wires 7, and an edible oil 8. The main part is composed of the metal container 5. The conductor electrode plate 4 is immersed in an installed metal container 5.

The power source device 1 is formed of an AC power source 2 and a first rectifier element 3 connected in series to the AC power source 2. The rectifier element 3 is energized only from the conductive electrode plate 4 side to the AC power source 2 side. Is connected so that energization from the non-grounded output terminal 2a of the AC power supply 2 to the conductive support 4 side is blocked.

  In FIG. 1, 1a is a case, 2a is an ungrounded output terminal of the AC power supply, 2b is a grounded output terminal of the AC power supply, 3a is an AC power supply side terminal of the commutator 3, 3b is an output terminal, and 4a is a terminal. , 6 is a ground point, 7 leads, v is a voltage waveform of the AC power supply, i is a current waveform, e is an electron, and C ′ is a stray capacitance. The edible oil may be new before use, or may be used or used.

When the sine wave AC power supply 2 is operated and a sine wave AC voltage v is generated between the terminals 2a and 2b, the conductor electrode is connected via the stray capacitance C 'formed between the conductor electrode plate 4 and the ground. The current i half-wave rectified by the rectifying element 3 flows from the plate 4 to the terminal 2 a side of the AC power supply 2 via the lead wire 7.
As a result, contrary to the current i, electrons e flow from the AC power source 2 side to the conductor electrode plate 4 side through the lead wire 7 and the amount of electrons (minus charge) of the conductor electrode plate 4 increases. As a result, the negative potential of the electrode plate 4 made of the conductor fluctuates.

  Similarly, since the current flow is blocked by the rectifying element 3, a part of the negative charges (electrons) disappears due to discharge while the electrons e are not supplied to the conductor support 4 through the lead wires 7. The amount of electrons will decrease, and this will also change the negative potential of the electrode plate 4 made of a conductor.

  As described above, the fluctuation of the negative potential generated in the conductor electrode plate 4, that is, the fluctuation of the amount of electrons inevitably causes the potential fluctuation or electric field fluctuation of the conductor electrode plate 4.

  In FIG. 2, the electrode plate 4 made of a conductor is tightly fixed to the side wall surface of the metal container 5, but there is a slight gap between the electrode plate 4 made of the conductor and the side wall surface of the metal container 5. It is also possible to provide the conductive electrode plate 4 in the vicinity of the metal container 5 by providing a gap.

As the power supply device 1, an AC power supply 2 having a frequency of 2 Hz to 200 Hz and a maximum transmission output of 10 watts is used, and the conductive electrode plate 4 is made of stainless steel (100 mm × 100 mm × 100 mm (height)). It was suspended and fixed vertically in a stainless steel container 5 having a diameter of 200 mmΦ and a depth of 200 mm.
And the unused new edible oil (vegetable tempura oil) 1500CC was put in the said container 5, and the antioxidant process for about 30 minutes was performed. The average output of the power supply 1 during processing was 5 watts.

  After completion of the antioxidant treatment, the processing time and the same kind of untreated edible oil are used, and the conditions such as the type and amount of the raw food, the heating temperature, etc. are the same, and the time for preparing the tempura A comparative survey was conducted on the texture of tempura, the turbidity of cooking oil, and the number of tempura that could withstand use.

  As a result, in the edible oil that was first subjected to the antioxidant treatment according to the present invention, the number of tempura that can withstand use can be increased by 1 to 5 times compared to the case of untreated edible oil, It has been confirmed. In this comparative test, it is needless to say that no oil is added or replenished during the tempura work.

In addition, a PN diode 9b is used as the second rectifying element 3 , and the current i flowing from the conductive support 4 to the power supply device 1 is used as the waveform of full-wave rectification. Only the difference is different from the embodiment of FIG.

It is connected to the ground output terminal 3b.

  Further, the LC resonance circuit 10 resonates with an external electromagnetic wave existing in an external space having a frequency of 2 KHz to 2000 KHz by varying the capacitance C, and induces an alternating voltage v 'having the resonance frequency. Then, a superimposed voltage vo of the alternating voltage v of the AC power source 2 having a frequency of 2 to 200 Hz and the alternating voltage v ′ having the resonance frequency is output between the ground output terminal 2 and the non-ground output terminal 3b. In FIG. 4, R is a safety resistance.

When the sine wave AC power supply 2 is operated and the LC resonance circuit 10 is tuned, the superimposed voltage vo is generated between the terminals 3b and 2b, and is superimposed through the lead wire 7, the conductor electrode plate 4, and the stray capacitance C ′. An alternating current by voltage vo flows.
Further, when an alternating current due to the superimposed voltage vo flows through the electrode plate 4 made of the conductor, the electric potential fluctuates and the electric field fluctuates, whereby the edible oil 8 is subjected to the antioxidant treatment as described above. It is.
