Definitions
- the invention relates to the preservation of food products, in particular of bread products.
- a preserving gas such as carbon dioxide, 5 is added to the product in order to counteract spores of, for example, moulds or germs of bacteria. Oxidation of the product is also prevented.
- the shelf life of such food products increases as a result.
- the object of the invention is therefore to provide a method which does not have these disadvantages, or has them to a lesser extent. That object is achieved by 5 the fact that the invention relates to a method for preserving a food product such as a bread product, comprising the steps of:
- At least one of the quantities of gas can comprise a preserving gas for counteracting microorganisms such as moulds and the like.
- auxiliary gas in particular nitrogen gas
- the vacuum created therein must after all be filled, and only nitrogen gas is available for 0 that purpose in this phase of the method according to the invention.
- Another advantage of the method according to the invention is that the gases need not be mixed beforehand. Prior mixing first of all leads to higher costs, and the quantity of carbon dioxide which can be mixed with nitrogen gas must not be too o great either. Since carbon dioxide is heavier than nitrogen gas, the quantity of carbon dioxide at a maximum pressure of approx. 200 bar must remain restricted to 30%, otherwise separation would occur. Such a mixture is available as a standard mixture.
- the proportions can be selected freely. Therefore, a quantity of 50% nitrogen gas, for example, can 5 be selected. A quantity of 50% carbon dioxide can then be added, with the result that an excellent preservative effect is ensured without appreciable change of flavour occurring.
- the method according to the invention can also be carried out according to a variant which is suitable in particular for bread products with moisture-containing o ingredients such as raisins, currants, (candied) fruits. Particularly in the case of soaked fruits, the problem can occur that the fruit starts to form alcohol.
- the method according to the invention can comprise the additional step of initially introducing into the chamber a first quantity of preserving gas before the steps of introducing into the chamber the auxiliary gas and introducing into the chamber a second quantity of preserving gas.
- the limited quantity of carbon dioxide introduced as a first step will only dissolve quickly in the ingredients with a relatively large amount of moisture. Introducing the nitrogen gas immediately after that ensures that said nitrogen gas can still penetrate into the bread product.
- the quantity of carbon dioxide introduced last then remains on the outside of the product.
- the final pressure in the pack obtained can be atmospheric or also slightly lower or higher.
- the invention also relates to a device for carrying out the method, comprising a chamber which can be sealed off in a gastight manner and is provided with an access, a vacuum pump connected to the chamber, for lowering the pressure in the sealed chamber, a first gas supply line which is connectable to a source of auxiliary gas, and at least a second gas supply line which is connectable to a source of preserving gas.
- Figure 1 shows a diagrammatic representation in section of the device according to the invention.
- Figure 2 shows an end view in section.
- the device shown in Figure 1 comprises a frame with wheels 2, on which the vacuum chamber, indicated in its entirety by 3, is accommodated.
- Said vacuum chamber comprises a fixed base part 4 and a cover 5 which can be opened and closed about hinge 6. An airtight closure is ensured by means of the seal 7 running around the cover 5.
- Two welding or sealing devices 8 are accommodated in a known manner in the vacuum chamber 3.
- Said devices 8 each comprise a top bar 9, which is fixed to the cover 5, and a bottom bar 10, which can be moved up and down.
- This gas is uniformly distributed over all nozzles 15 by means of the main line 16.
- an auxiliary gas such as nitrogen gas, for example, to flow into the packs 13 by opening valve 21.
- an atomizer 23 can be accommodated in one of the lines, in order to atomize a flavouring product, such as a liqueur flavour, into the gas.
- Main line 16 is also connected by means of bypass line 24 with non-return valve 25 to the chamber 3. It can be ensured in this way that the chamber 3 can be filled sufficiently rapidly with gas, which benefits the speed of production. If the gas had to be injected completely through the nozzles 15, too strong a flow could occur, which can have an adverse effect on the packs 13.
