Description
- The present invention relates to a container assembly for fermenting food and a related method.
- The present invention has been developed for household use in fermenting or pickling food such as vegetables (such as potatoes and cabbage), meats, fruits, fish, grains, nuts and olives and will be described hereinafter with reference to this application. However, the invention is not restricted to this particular use and also suitable for creates starters for milk, cream, yoghurt, butter and sourdough bread, batters, ginger bugs, miso paste, natto, condiments (such as mustard), fish sauce, tomato sauce, cheese and soft drinks.
- It is known to ferment food in glass jars that have a sealable lid. The lid being modified to allow an air lock valve to be attached. Generally speaking, fermenting in such glass jars is inconvenient, messy, difficult and often leads to food spoiling during the fermentation process.
- It is important that the food being fermented, and the surrounding fermenting liquid, be isolated from the external environment in order to prevent outside air, and dust airborne bacteria, establishing itself within the food. If this occurs, mould growth (both benign and potentially poisonous) can occur. Creating and maintaining an airtight sealed container is difficult as the fermenting process generates gases which cause a build-up of pressure inside the jar. If the gas is unable to escape, the seals between the container and its lid can blow out, causing leakage of the contents and, in extreme cases, shattering of the glass jar. The use of one way airlock valves to vent the gases is known, primarily those suitable for home brewing of wine and other alcoholic beverages. The disadvantages of using such valves is they are excessively large relative to the size of most jars used for fermenting, they can be difficult to operate and they make storage and handling of the jars difficult.
- The quality and taste of food being fermented can be diminished if they are are not isolated from light during fermentation. Known methods of achieving this are to wrap the jar in fabric material or placing it in a light free environment for the duration of the fermentation process. The disadvantages of these approaches is that the former is often not particularly effective at blocking light transmission and the latter restricts where in a household the fermenting jars may be stored.
- It is also important during fermentation that the container is accurately filled with food, brine and the one way valve with water. If incorrect levels are used, leakage can occur, the quality of the food can be diminished and the one way valve may not correctly function. The disadvantage of existing containers is overfilling is a common issue, often leading to leakage and mess.
- Accordingly, in a first aspect, the present invention provides a container assembly for fermenting food, the container assembly including:
- a container having an upper open end communicating with an internal volume for receipt of food and fermenting liquid;
- a pusher at least partially insertable through the opening and having a pushing surface protruding into the internal volume for limiting the maximum height of the food in the internal volume; and a lid for the opening with a one way valve therein adapted to allow fluid communication from the internal volume to atmosphere and prevent fluid communication from atmosphere to the internal volume.
- The one way valve is preferably within the external boundary of the lid. The one way valve is preferably substantially within the external boundary of the pusher.
- The pusher surface preferably includes one or more openings therein for passage of the fermenting liquid, thereby allowing the fermenting liquid to be filled to above the maximum height of the food in the internal volume. The pusher preferably includes a maximum liquid level indicator therein.
- The container assembly preferably includes a first sealing gasket between the exterior of the pusher and the interior of the upper open end.
- The lid preferably releasably engages with the container with the pusher sandwiched therebetween. The lid preferably releasably engages with the container via a bayonet type connection. The container assembly preferably includes a second sealing gasket between the exterior of the container and the interior of the lid.
- The one way valve preferably includes an upwardly facing reservoir around an opening and a downwardly facing reservoir around the opening and within the upwardly facing reservoir. The downwardly facing reservoir is preferably part of a cap that is releasably engageable with the lid. The cap preferably includes one or more openings therein through which fluid can be added to the upwardly facing reservoir.
- The container preferably includes a stainless steel external base. The container is preferably transparent. The container assembly preferably includes a removable opaque outer sheath, most preferably formed from silicon rubber.
- Accordingly, in a second aspect, the present invention provides a method for fermenting food, the method including the steps of:
- adding food to an internal volume of a container;
- at least partially inserting a pusher into the internal volume to limit the maximum height of the food in the internal volume;
- adding fermenting liquid to the internal volume to a height above the maximum height of the food in the internal volume; and
- closing the internal volume with a lid having a one way valve therein adapted to allow fluid communication from the internal volume to atmosphere and prevent fluid communication from atmosphere to the internal volume, whereby gases generated by the fermenting process can escape the internal volume without causing pressurisation of the container.
- The step of adding the fermenting liquid preferably includes passing the fermenting liquid through one or more openings in the pusher.
- The method preferably includes the step of securing the pusher to the container using the lid.
- The method preferably includes the step adding a removable opaque sheath to the exterior of the container.
