Just as a painter needs a steady canvas, a cook needs a durable cutting board to ensure precise and safe cuts.
However, the durability of a cutting board is greatly influenced by the material it is made from, and each material – be it plastic, wood, bamboo, or composite – comes with its own unique characteristics and maintenance needs.
Understanding these nuances can help us make informed decisions in choosing the right cutting board, and more importantly, in taking proper care of it to prevent unnecessary damage such as cracking.
We will be discussing the most common reasons for cracking in cutting boards, starting with the material used to make them.
We will also go through a set of prevention and maintenance tips to ensure that your cutting board is always up to the task.
Understanding Cutting Board Materials
Wood
Wood is a classic choice for cutting boards due to its durability and natural aesthetics. It can withstand heavy use without dulling knives and typically resists warping. However, wood is also highly susceptible to moisture, and without proper care, it can crack or split over time.
Plastic
Plastic cutting boards are lightweight, easy to clean, and come in a variety of colors. They are also relatively inexpensive.
However, they can harbor bacteria in the grooves caused by cutting and can warp or crack under high heat.
Bamboo
Bamboo cutting boards are an eco-friendly option as bamboo is a rapidly renewable resource.
These boards are hard, durable, and naturally resistant to moisture, reducing the risk of warping and cracking. However, their hardness can also dull knives faster than wood.
Glass
Glass cutting boards are non-porous, making them resistant to bacteria and easy to clean. However, they are tough on knives, and the hard surface can lead to slipping, therefore they are less recommended for heavy cutting tasks. Besides, glass boards can shatter when dropped.
Composite
Composite cutting boards, made from a combination of wood fibers and resin, offer a good balance between the durability of wood and the ease of cleaning offered by plastic.
They are dishwasher-safe and highly durable. However, they are typically more expensive than other options and can also dull knives over time.
Marble
Marble cutting boards are aesthetically pleasing and stay cooler than room temperature, which is beneficial for preparing certain foods, such as pastries.
However, they are the hardest and can dull knives very quickly. Additionally, marble is porous and may absorb oils and bacteria if not properly sealed, which could lead to cracking over time.
Cutting Board Materials Prone to Cracking
Certain cutting board materials are notably more susceptible to cracking due to various factors including moisture absorption, significant temperature changes, and inherent natural properties.
Wood
Wooden cutting boards, despite their natural beauty and efficacy, can be prone to cracking. The primary reason for this susceptibility lies in the nature of wood itself.
Being a naturally porous material, wood can absorb moisture. If not adequately treated and dried, this excessive moisture can cause the wood to swell and contract, leading to eventual cracks.
Moreover, extreme temperature changes can further exacerbate this process, causing the board to warp and consequently crack.
Bamboo
While bamboo cutting boards are resistant to moisture, they are not entirely immune to cracking. The composition of bamboo—fibrous and dense—can lend itself to splitting under certain circumstances.
The hardness that makes bamboo durable can also make it brittle, particularly if the board is exposed to high temperatures or extremely dry conditions. This can cause the bamboo fibers to dehydrate and shrink, leading to cracks.
Plastic
Plastic cutting boards, despite their durability and ease of cleaning, are not exempt from the risk of cracking. The primary factor contributing to cracking in plastic boards is high heat, which can warp the shape of the board and ultimately lead to fissures.
Additionally, over time, the grooves made by the knife can weaken the plastic structure of the board, making it increasingly vulnerable to cracking.
Reasons Your Cutting Board is Cracking
1. Low-Quality Materials
Cutting boards manufactured from low-quality, inexpensive materials are more susceptible to cracking.
The poor resilience of such materials makes them unable to withstand prolonged cutting action, temperature fluctuations, and other forms of stress.
Consequently, they readily absorb moisture and warp, leading to the formation of cracks over time.
2. Improper Drying
Improper drying of cutting boards, especially those made from natural materials like wood and bamboo, can result in moisture retention.
This surplus moisture causes the board’s material to expand and contract inconsistently, leading to cracks.
It’s crucial to ensure that cutting boards are thoroughly dried after cleaning to avoid such issues.
3. Knife Marks and Excessive Force
Excessive force during cutting and deep knife marks can compromise the structural integrity of the cutting board.
Each cut made into the board creates a weak point where cracks can form over time. Hence, maintaining appropriate pressure during cutting is crucial for the longevity of the board.
4. Age and Wear
Over time, regular wear and tear can contribute to the cracking of cutting boards. As the board ages, its resilience diminishes, making it more prone to cracking.
Regular maintenance and proper care can slow down this process, extending the life of the cutting board.
5. Lack of Maintenance
Neglecting regular maintenance such as oiling and seasoning can lead to drying and cracking of the board, particularly those made from natural materials. Regular maintenance keeps the board’s material hydrated and resilient, preventing cracking.
6. Moisture and Absorption
Moisture absorbed by materials like wood and bamboo causes them to swell. When this moisture subsequently evaporates, it can cause the material to contract, leading to cracks. This makes it critical to avoid soaking these boards and to dry them promptly after cleaning.
7. Temperature Fluctuations
Rapid changes in temperature can cause cutting boards to expand and contract, leading to cracks.
This is particularly true for wooden and bamboo boards, which are highly sensitive to temperature changes.
8. Exposure to Sunlight
Prolonged exposure to sunlight can dry out cutting board materials, making them brittle and prone to cracking.
The ultraviolet rays can break down the structure of the board’s material, leading to warping and cracking.
9. Excessive Heat
Placing hot pots or pans directly on cutting boards, especially plastic ones, can cause warping and the development of cracks.
The excessive heat distorts the shape of the board and, over time, can lead to cracks forming.
10. Dishwasher Usage
Exposure to the high heat and harsh detergents used in dishwashers can make plastic cutting boards more prone to cracking. The intense conditions can cause warping and weaken the structure of the board, leading to cracks.
11. Storage Conditions
Improper storage, particularly in humid environments, can accelerate the development of cracks in cutting boards.
Humidity can cause boards, especially wooden ones, to absorb moisture and subsequently crack.
12. Inadequate Cleaning
Using harsh chemicals for cleaning or not cleaning the board properly can cause damage, making it more prone to cracking.
Harsh detergents can strip the board of its natural oils, leading to drying and cracking, while residue from improperly cleaned boards can promote bacterial growth and weaken the board’s structure.
13. Inappropriate Knife Choice
Using knives that are too heavy or dull can stress the surface of the cutting board, leading to cracking and warping.
A knife that is too dull can cause excessive rocking while chopping, which can weaken the surface of the board and lead to cracking.
Prevention and Maintenance Tips
To extend the life of your cutting board and prevent it from cracking or warping, consider the following practical maintenance and preventative measures:
- Choose High-Quality Materials
Invest in a cutting board made of high-quality materials. Look for durable, thick boards that can withstand repeated use.
