Definitions

  • the present invention relates to packaging means containing liquid yeast.
  • Liquid yeast is a suspension of baker's yeast cells with a yeast dry matter content usually between 5 and 25% (w/w).
  • Cream yeast is a special form of liquid yeast. It is a product that is obtained directly after the fermentation step in the yeast production process, optionally after one or several washing steps. Cream yeast usually has a dry matter content between 17 and 23% (w/w). Alternatively, liquid yeast can be obtained by resuspending compressed yeast or dry yeast.
  • Liquid yeast can also be in the form of an oil-in-water emulsion as disclosed in JP 2-124054. Liquid yeast also comprises the high-
  • Liquid yeast products are currently available in two forms. The first one is unstabilised and needs to be stirred in order to prevent sedimentation of yeast cells. The second one is a stabilised one that remains homogeneous due to the presence of a stabiliser such as xanthan gum (EP-A-0461725). Liquid yeast may further comprise one or more processing aids with dough and/or bread improving properties.
  • This container is usually made from materials such as cardboard (optionally supplied with a plastic or alumina coating), glass, polycarbonate, PET, HDPE (high densiy polyethylene), tinplate and other suitable food grade materials.
  • Other packaging means that are used in the food industry for the storage and supply of for instance wine, cream, egg products and the like consist of a container in a support structure such as a bag-in-box, Gerry)can-in-box etceteras. All these packaging means are equipped with fittings or caps that completely close the container or the bag and are therefore impermeable for both liquid and gas.
  • these packaging means are not suited for the storage of liquid yeast, because the accumulation of gaseous CO, (produced by the yeast cells as a result of their metabolism) will increase the pressure inside and eventually blow up and destroy the packaging means. This will not only waste the yeast product but also lead to potentially dangerous situations for the user.
  • Figure 2 shows the open folded structure of a cardboard box supplied with an incision as ventilating means. It is made up of panels 1-4 and a fifth panel (5). Upon mounting the cardboard box, the fifth panel is sealed to panel 1. Further dimensions are as in Figure 1. The length of the incision is 15 mm and the distance between the incision(s) and the edge of the horizontal fin crease is approximately 1 mm.
  • the present invention provides packaging means comprising a container containing liquid yeast characterized in that the container is equipped with means to release overpressure and that the container has a volume between 0.1 and less than 100 liter. Preferably the volume of the container is between 0.1 and 80 litres.
  • the means to release overpressure may comprise a ventilating cap.
  • a ventilating cap is defined herein as a cap that allows the permeation of gas but does not allow the permeation of liquid.
  • This ventilating cap may be screwed or snapped on the container containing liquid yeast and enables the release of gas from the inside while at the same time the ventilating cap prevents the liquid yeast from leaking out.
  • Suitable ventilating caps may comprise a sieve that is fixed to the inner side of the cap. These caps may further comprise one or more holes located in the top wall of the cap. When holes are present in the cap, the gas can escape from the container through the holes while in the absence of holes, the gas can escape along the screw thread of the cap.
  • the sieve can be made from a ventilating microporous membrane material that is permeable to gas and impermeable to liquids.
  • the cap may also contain an overpressure releasing mechanism inside the cap that opens above a certain threshold value, for instance 10 mbar.
  • the means to release overpressure may also comprise one or more incisions made in the container itself, preferably in the top part of the container.
  • the size of the incisions is usually dependant on the size of the container.
  • the incision may be covered with a ventilating membrane made from a microporous material, preferably on the inside of the container.
  • the entire container, or at least a part thereof is made from a microporous material thus providing the container the means to release the overpressure.
  • Suitable microporous materials to be used for the packaging means of the invention comprise PTFE (polytetrafluoroethylene) or UHMW-PE (ultra high molecular weight such as SoluporTM from DSM Solutech, The Netherlands).
  • the microporous material may have a pore size of 0.05-5.0 micron, preferably 0.1-2.0 micron.
  • the container can be made from any food grade material.
  • the container can be made from cardboard which is optionally equipped with a plastic coating such as polyethylene or an alumina coating .
  • These cardboard containers can be supplied both with one or more ventilating caps or with one or more incisions.
  • Cardboard containe r s containing liquid yeast preferably have a volume between 0.1 and 5 litres, more preferably between 0.25 and 4 liters and most preferably between 0.5 and 3 liters.
  • these incisions are preferably located in the top seal of the pack. The incisions may be small linear cuts, made in the centre of the top seal, close to the top horizontal fin crease.
  • the length of the cuts may be between 1-80 mm, preferably between 5-50 mm and more preferably 10-20 mm; the maximum value being dependent on the dimensions of the pack.
  • the distance between the incision(s) and the edge of the horizontal fin crease is preferably less than 5 mm and more than 0.5 mm, more preferably less than 2 mm and more than 05 mm, most preferably approximately 1 mm.
  • One incision can be made in the seal. In case 2 incisions are present, they can be present in the same horizontal plane or on both sides of the top fin.
  • the pack's upper seal is made in the normal manner by melting the polyethylene material and by pressing the opposite layers against each other. In this way, the incision is in the "closed" position. Turning the pack upside down does not lead to leakage of liquid product from the pack. Only at a certain overpressure, the incision opens and CO 2 -release may take place.
  • the container may also be a bottle or (jerry)can made from a suitable food-grade material such as PET and HDPE. These containers are supplied preferably with a ventilating cap that is screwed or snapped onto the container.
  • the packaging means additionally comprise a support structure, such as a box, holding the container.
  • the container can be made from materials such as polyethylene, nylon, EVOH, MPET or combinations thereof.
  • the container may be made from microporous materials as described above.
  • the box can be made from cardboard. It may be coated in order to prevent the carton from becoming weak in case condensation of water would occur.
  • These packaging means may have a volume between 1 and less than 100 liters and preferably have a volume between 5-50 liters and more preferably between 10-30 liters.
  • the packaging means provided by the invention contain liquid baker's yeast.
  • the liquid baker's yeast has a dry matter content between 5 and 25% (w/w), more preferably between 17 and 23% (cream yeast).
  • the liquid yeast further comprises a gum, such as xanthan.
  • the liquid yeast product may also comprise one or more processing aids with dough and/or bread improving properties, such as enzymes, ascorbic acid, emulsifiers and thelike.
  • the packaging means that are provided by the invention allow the artisanal bakers to use liquid yeast, in particular cream yeast as well, just like large-scale bakeries.
  • the packaging means may be used by the baker as follows.
  • the liquid yeast may be transferred from the packaging means to a scaes or a measuring beaker using a simple tap, a dispenser system or a small pipe and a membrane pump or poured directly to the (dough) mixer in case the yeast volume matches the amount of yeast required for the preparation of the dough.
  • the packaging means may also be put in a pressure vessel and external air pressure may be used to empty the container. Obviously, depending on the demands of the baker, automation of yeast dosage is also possible, for instance by putting the packaging means on load cells and using a pump, a dosing valve and a computer.
  • Example 1 Different packaging means were constructed, all containing a carton box and a liner made of LLDPE (Linear Low Density Polyethylene) with a volume of 20 litres and a spout equipped with a screw thread to mount a screw cap.
  • LLDPE Linear Low Density Polyethylene
  • Ventilating cap with a PTFE membrane fixed to the inside 4. Ventilating cap with 1 hole of 1.0 mm diameter located in the top wall of the cap and a PTFE membrane fixed to the inside of the cap.
  • Ventilating cap with 5 holes of 1.0 mm diameter located in the top wall of the cap and a PTFE membrane fixed to the inside of the cap.
  • Table 1 Storage of stabilised cream yeast in packaging means supplied with various means to release overpressure at 20°C.
  • the glucose conversion was calculated from the decrease of yeast dry matter, and the decrease of trehalose and glycogen that took place during the storage period, using the following equation (in grams / kg yeast dry matter)
  • Example 1 Different packaging means were used, all consisting of a single 1 litre cardboard box equipped with a polyethylene coating on the inside and a spout equipped with a screw thread to mount a screw cap (see Figure 1). As ventilating means, the same caps were used as those of Example 1. All packaging means were filled with circa 1 litre of o commercially available stabilised cream yeast ("Koningscream" - produced by DSM in Delft, the Netherlands). The boxes were stored at a temperature of 20°C during 3 weeks and they were shaken regularly in order to stimulate the release of gas from the cream yeast fluid. The results were as depicted in Table 3: Table 3. Storage of stabilised cream yeast in packaging means supplied with various means to release overpressure at 20°C.
  • stabilised cream yeast in packaging means supplied with various means to release overpressure at 20°C.
  • packaging means comprising of a single cardboard container and supplied with a closed cap, cannot be used for the storage of liquid yeast.
  • Packaging means with a ventilating cap are very well suited and behave as good as boxes supplied without cap. When the liquid yeast containing boxes with the ventilating caps were shaken, some expansion occurred, however, within a short time, the boxes resumed their original shape.
  • Example 4 Two 1 -litre cardboard boxes as described in Example 2 were used. One box was supplied with one incision as the overpressure releasing means.
  • panel 1 was provided with an incision in the top fin seal. The length of tie incision was 15 mm and the distance between the incision(s) and the edge of the horizontal fin crease was approximately 1 mm.
