Cutting board
Encyclopedia
A cutting board is a durable board on which to place material for cutting. Common is the kitchen cutting board used in preparing food; other types exist for cutting raw materials such as leather or plastic.
Kitchen cutting boards are often made of wood
Wood
Wood is a hard, fibrous tissue found in many trees. It has been used for hundreds of thousands of years for both fuel and as a construction material. It is an organic material, a natural composite of cellulose fibers embedded in a matrix of lignin which resists compression...

Steel is an alloy that consists mostly of iron and has a carbon content between 0.2% and 2.1% by weight, depending on the grade. Carbon is the most common alloying material for iron, but various other alloying elements are used, such as manganese, chromium, vanadium, and tungsten...

, which are easier to clean than wooden or plastic ones such as nylon or corian, but tend to damage knives due to their hardness. Rough cutting edges — such as serrated knives — abrade and damage a cutting surface more rapidly than do smooth cutting implements.

Sanitation and care

Regardless of the material, regular maintenance of a cutting board is important.
  • Sanitation with cutting boards is a delicate process because bacteria can reside in grooves produced by cutting, or in liquids left on the board. For this reason, it is often advised to cut raw meat

     solution is best for disinfecting cutting boards.
  • To remove odors, rinse the board and then rub with coarse salt and let stand for several minutes. Wipe the board and then rinse it clean. This procedure will also smooth out minor imperfections in the wood.
  • Wooden boards should never be placed in the dishwasher, or left immersed for long periods, as the wood or glue may be affected.

    Drying oil
    A drying oil is an oil that hardens to a tough, solid film after a period of exposure to air. The oil hardens through a chemical reaction in which the components crosslink by the action of oxygen . Drying oils are a key component of oil paint and some varnishes...

    Tung oil or China wood oil is a drying oil obtained by pressing the seed from the nut of the tung tree . As a drying oil, tung oil hardens upon exposure to air.

    . The first two dry much faster than linseed. Note that most commercially available linseed and tung oils are not “food grade”, as they contain metallic driers. In general, edible savory vegetable or olive oils are not recommended because they tend to go rancid, causing the board to smell and your food to pick up the rancid taste.
  • To prevent cracking, cutting boards should be treated when they start looking dry. A standard recommendation is 5-7 times a year, or as needed.
  • When heavily or deeply scored, wood or plastic cutting boards should be resurfaced, as scoring can harbor bacteria, or mildew

    A hand plane is a tool for shaping wood. When powered by electricity, the tool may be called a planer.

    Sandpaper, also known as glasspaper, is a heavy paper with abrasive material attached to its surface.Sandpaper is part of the "coated abrasives" family of abrasive products. It is used to remove small amounts of material from surfaces, either to make them smoother , to remove a layer of material...

     is to be avoided, as it leaves in the surface residual abrasives which will dull knives. Resurfacing a plastic cutting board is more difficult and replacing it is recommended instead.

Materials

A knife edge is a delicate structure and can easily be blunted by too abrasive a surface. Alternatively, it can be chipped if used on a surface that is too hard. A good cutting board material must be soft, easy to clean, and non-abrasive, but not fragile to the point of being destroyed. Hard cutting boards can, however, be used for food preparation tasks that do not require a sharp knife, like cutting cheese or making sandwiches.

Wood

Wood has some advantages over plastic in that it is somewhat self-healing; shallow cuts in the wood will close up on their own. Wood also has natural anti-septic properties.

Hardwoods with tightly grained wood and small pores are best for wooden cutting boards. Good hardness and tight grain help reduce scoring of the cutting surface and absorption of liquid and dirt into the surface. Red oak

 for example, even though a hardwood, has large pores, so it retains dirt even after washing, making it a poor choice for cutting-board material.

Teak

's tight grains and natural coloration make it a highly attractive cutting-board material, both for aesthetic and durability purposes. Teak, a tropical wood, contains tectoquinones, components of natural oily resins that repel moisture, fungi, warping, rot and microbes.

Wood boards need to be cared for with mineral oil to avoid warping, and should not be left in puddles of liquid.

Care must be taken when selecting wood, especially tropical hardwood, for use as a cutting board, as some species contain toxins or allergens.

 also make an attractive and durable cutting-board material.

Plastic

While plastic is theoretically a more sanitary material than wood for cutting boards, testing has shown this may not be the case. The softer surface of plastic boards is scored by knives, and the resulting grooves and cuts in the surface harbour bacteria even after being well washed. A plastic surface can also ruin the sharp edge of the knife. However, unlike wood, plastic boards do allow rinsing with harsher cleaning chemicals such as bleach and other disinfectants without damage to the board or retention of the chemicals to later contaminate food.

, the material of which these boards are made.

Semi-disposable thin flexible cutting boards also ease transferring their contents to a cooking or storage vessel.

Rubber

A recent trend has seen thick solid rubber pads used as cutting boards in the Sani-Tuff line popular in restaurant kitchens. They are about as expensive as well-made wood boards, they can take chemical disinfectants, and they are very heavy for their size, so they tend not to slip. Proponents claim remarkable self-healing properties, the same knife protection as good plastic or wood boards, and an inability to harbor significant amounts of moisture or bacteria.

Glass

While glass looks like an easy surface to keep clean, glass cutting boards can damage knives because of the high hardness of the material. Cutting on glass tends to dent, roll or even chip knife edges in a rapid manner. Additionally, if used for chopping instead of slicing, glass can shatter or chip itself, contaminating food.

shares with glass the advantages of the durability and ease of cleaning, as well as the tendency to damage knives. Depending on the exact steel and heat treatment used, at best a steel cutting board will wear the edge on knives quickly; at worst chip, dent, or roll it like glass.
