Definitions
- the present invention relates to the food industry and in particular the milk industry, but more generally, the invention relates to liquids which are going to be fermented, in particular by lactic acid bacteria. This is the case with milk, to which bacteria are added to produce yogurt, cheese, etc. but this can also be the case for soy milk for example.
- Lactic acid fermentation is the process by which lactic acid bacteria develop, under anaerobic conditions, by producing lactic acid from the carbohydrates present in the product that is fermented (lactose in the case of milk).
- Lactic acid bacteria which include, for example, lactobacilli, streptococci, bifidobacteria, leuconostocci and enterococci, are anaerobic bacteria, partially tolerant to oxygen.
- the growth curve of bacteria during lactic fermentation is the same as for any other fermentation and includes:
- a latency phase during this phase the growth rate is zero or almost zero. It is the time necessary for bacteria to adapt to the composition of the substrate (medium in which fermentation takes place), and produce the enzymes necessary for its use. The duration of the latency phase therefore depends on the composition of the fermentation medium.
- a lever to improve the productivity of lactic fermentation is to reduce the lag phase.
- a low level of dissolved oxygen in milk at the start of fermentation reduces the duration of the lag phase.
- the dissolved oxygen in milk would delay the production of lactic acid.
- Vacuum degassing will protect the product from oxidation just before the pasteurization stage, but nothing is done after this stage, the product will then inevitably take up oxygen (via air) during the following stages of process.
- One of the objectives of the present invention is therefore to propose a new fermentation process having a better productivity than a traditional process because implementing a fermentation medium having a level of dissolved oxygen almost zero, without the need for a step vacuum or nitrogen deoxygenation as according to the prior art.
- the present invention proposes to work under the following conditions where the liquid, for example milk, but the targeted “liquid” can also be a mixture, for example a mixture for producing a yogurt, in particular undergoes the following steps:
- an injection into the line, downstream or upstream of pasteurization, of a small amount of nitrogen to rebalance the milk with nitrogen For example, injecting a flow of nitrogen (nitrogen or another gas, including CO2) of between 5 and 50 g per cubic meter of liquid, preferably between 10 and 30 g / m 3 , in order to bringing the liquid to equilibrium after cooling after pasteurization;
- nitrogen nitrogen or another gas, including CO2
- a little CO2 (or a gas comprising CO2), for example an amount between 20 and 1500 mg / l, preferably an amount between 150 and 900 mg / l can be injected (dissolved) in the liquid: online (before arriving in the tank) or in a tank upstream, in order to pre-lower the pH and thus further reduce the fermentation time.
- fermenting a liquid means lowering its pH by the action of bacteria, which produce lactic acid.
- the pH drops with the development of lactic acid bacteria, when the pH reaches 4.6 (isoelectric pH of caseins, major proteins in milk), the quail milk, forming a gel.
- CO2 we lower the pH a little faster, supporting the work of bacteria. This small amount of dissolved CO 2 will also have the advantage of more effectively protecting the milk from possible oxygen uptake via air during transfers into partially inert containers.
- liquids to be fermented for example yogurts
- liquids which result from the mixture of several liquid and possibly solid ingredients for example by considering the case of one of a yogurt, the liquid which will be fermented, and which will therefore pass into the pasteurizer before sowing, is a mixture of milk, powdered milk protein, possibly sugar, possibly cream, etc.
- the mixing of these ingredients is carried out under inerting in order on the one hand to remove the dissolved oxygen present in the ingredients, and on the other hand to avoid the incorporation of oxygen because of the very action of mixing.
- the present invention takes advantage of the fact that the residual oxygen in the liquid, for example milk, at the outlet of pasteurization is very low and that the tank is inerted BEFORE the arrival of the liquid.
- the present invention we do not oxygenate not, we avoid the recovery of oxygen, which consumes less gas, and by the fact that inerting takes place in parallel with pasteurization we do not add additional step time.
- Figure 1 attached illustrates a partial schematic view of an installation suitable for the implementation of the invention.
- an inline gas injector for example a Venturi system
- the present invention therefore relates to a method for producing a fermented edible liquid, comprising the following steps:
- the tank was, before the arrival of the liquid, previously inerted, for example by scanning the head space of the tank using a neutral gas such as nitrogen, containing or not CO2.
