Definitions
- the invention relates to a method for preserving a food in a hydrogen atmosphere in a package with one of a
- the interior being a food room to accommodate the
- the invention also relates to packaging of the aforementioned type.
- Hydrogen has an antioxidant effect and can ensure a longer shelf life and longer fresh-looking food. Due to its antioxidant effect, hydrogen can reduce the redox potential of the food; this can e.g. at
- Baby food can be used to better reproduce the properties of natural breast milk, which has a redox potential of up to -70mV, in replacement products.
- the antioxidant effect of hydrogen means that other preservatives or antioxidants can be reduced or dispensed with entirely.
- Water enriched with hydrogen is usually placed in flexible bags or metal cans made of a material that inhibits hydrogen diffusion
- Ambient pressure filled With flexible bags, usually one or more thin metal foils used to inhibit hydrogen diffusion. In order to increase the shelf life, the filling is either gas-free, so that the
- Packaging is completely filled with water enriched with hydrogen (mostly in the case of beverage cans) or with a small volume of hydrogen gas in addition to the water enriched with hydrogen (in the case of film packaging).
- Water enriched with hydrogen can also be mixed with hydrogen gas bubbles for a longer shelf life. Nano or microbubbles are usually used for this, as these remain stable in water longer than
- the hydrogen content in the water drops by approx. 14% to 75% within 6 months, depending on the type of packaging.
- Hydrogen enriched water is a health product, so it is important to keep this water as pure as possible. Therefore, the
- the object of the invention is to provide an inexpensive, simple and safe
- the subject matter of the present invention provides a method according to claim 1 which solves the technical problem. Likewise, the task is performed by a
- a method according to the invention serves to preserve a foodstuff, for example water enriched with hydrogen, in a foodstuff, for example water enriched with hydrogen, in a foodstuff, for example water enriched with hydrogen, in a foodstuff, for example water enriched with hydrogen, in a foodstuff, for example water enriched with hydrogen, in a foodstuff, for example water enriched with hydrogen, in a foodstuff, for example water enriched with hydrogen, in a
- the package comprises one of a hydrogen permeable and airtight
- the interior comprises a food space for receiving the food and a hydrogen space for receiving hydrogen gas, wherein the food space and the hydrogen space are at least gas-connected to each other.
- the food space and the hydrogen space can be connected to one another in a fluid-conducting manner, in particular in a conducting manner for the foodstuff.
- the hydrogen space and the food space can be located directly on at least one contact surface, that is to say without a physical barrier between the hydrogen space and the
- the shell and / or a sleeve surrounding the hydrogen space is in one
- Dimensional stability can be achieved, for example, by a sufficiently rigid material of the sheath and / or sleeve, a sufficiently high material thickness, a suitable shape of the Cover and / or sleeve, for example with beads, folds, waves and / or ribs for stiffening, and / or a support structure arranged in the cover and / or sleeve, for example by a lattice cage.
- the food is granular, for example as a loose powder
- the food can support the casing in such a way that it is dimensionally stable when it is filled with the food, with the spaces between the
- Food grains can form the hydrogen space.
- the sleeve can comprise a hollow body, comprising, for example, a plastic, a metal and / or a glass, for receiving the hydrogen gas.
- a hollow body can accommodate a particularly large volume of hydrogen gas for a given weight and material expenditure.
- the sleeve can comprise a, in particular at least in its interior open-pored, solid foam, comprising, for example, a foam, a rigid foam, an airgel and / or a metal foam, for absorbing the hydrogen gas.
- a foam offers the advantage that, compared to a hollow body, it offers improved mechanical stability, in particular against an external pressure acting on the foam.
- the method comprises filling the food at least into the
- Hydrogen space airtight sealing of the envelope, preferably after filling and introduction, and generating a negative pressure at least in the hydrogen space with respect to the surroundings of the packaging.
- a shell that is permeable to hydrogen has proven to be advantageous in the context of the method according to the invention. This is because part of the hydrogen gas that has been filled in can escape from the hermetically sealed packaging through such a cover, so that a negative pressure is established therein, or an adjusted one
- the casing of the packaging and / or the sleeve is designed to be dimensionally stable. If, for example, water enriched with hydrogen is filled with hydrogen gas in a previously customary packaging, for example a foil bag or a beverage can, the packaging does not withstand the negative pressure that occurs and deforms. This leads to a complete escape of the hydrogen gas from the packaging.
- the envelope In order to prevent gases other than hydrogen from entering the packaging in the event of a negative pressure, the envelope is designed to be hermetically sealed.

- the hydrogen content is determined by titration with methylene blue in solution with platinum nanoparticles (H2 Sciences Inc., USA). Hydrogen can dock onto the methylene blue via the platinum particles, which act as a catalyst, thereby changing its color from blue to transparent.
- the glass bottles are customary drinks bottles that are hermetically sealed with their associated plastic screw caps after the hydrogen gas has been introduced.
- the hydrogen-enriched water is first produced in a sufficiently large water dispenser so that the water has the same initial hydrogen content for all bottles in a test series. Distilled, non-degassed water is used. A separate bottle is used for each measuring point. The bottles are stored at at least 16 ° C and in the dark.
- the method according to the invention achieves a higher hydrogen content than the method from the prior art.
- FIG. 19 shows a pressure p in mbar in a package of with a
- Process according to the invention preserved water depending on a
- the pressure p inside the packaging in relation to an ambient pressure of the packaging is measured by bottle pressure gauges which are screwed onto the bottles or fastened with a swing top.
- the pressure in the packaging also drops relatively quickly initially, in particular within the first 30 days. Thereafter, the decrease in pressure as well as the decrease in the hydrogen content slow down significantly and appears to stabilize at an equilibrium value of approximately -150 mbar to -250 mbar compared to the ambient pressure.
- FIG. 20 shows a hydrogen content c in ppm of water preserved using a method according to the invention, depending on the water that has been filled
- the hydrogen content is determined as described for FIG.
- the specified hydrogen volume V of hydrogen gas is introduced into water with an initial hydrogen content c of 1.6 ppm in a bottle with a total volume of 1 L, the bottle being completely filled with water before introduction.
- the diagram shows that a certain minimum volume of hydrogen gas of around 50 mL to 60 mL in the example shown is necessary in order to obtain a maximum hydrogen content in the water during storage. A further increase in the hydrogen volume does not lead to an increase in the hydrogen content and should therefore be avoided for economic and safety reasons.
- FIG. 21 shows a hydrogen content c in ppm of water preserved with a method according to the invention as a function of a storage period t in days (d) in tests continued over a longer period from the test series already shown in FIG.
- the hydrogen-enriched water is prepared beforehand in a sufficiently large water dispenser so that the water has the same initial hydrogen content for all bottles in a test series. Distilled, non-degassed water is used. A separate bottle is used for each measuring point. The bottles are stored in the dark at a temperature between 16 ° C and 26 ° C and an ambient pressure of 992 mbar to 1034 mbar.
- FIG. 22 shows a pressure p in mbar in a package of with a
- Process according to the invention preserved water depending on a
- the water is filled and stored as described for FIG.
- the pressure p inside the packaging in relation to an ambient pressure of the packaging is measured by bottle pressure gauges, which are screwed onto the bottles instead of the associated lids or fastened with a clip-lock.
