Introduction to Tinned Tomatoes
Tinned tomatoes are a staple ingredient in many cuisines around the world. They offer a convenient and affordable way to add flavor and nutrients to a variety of dishes, from sauces and soups to stews and braises. The process of canning tomatoes involves harvesting, sorting, and packing the tomatoes into airtight containers, which are then heated to kill off bacteria and extend shelf life. This process allows tinned tomatoes to be stored for long periods without refrigeration, making them a popular choice for many consumers.
The Production Process
To understand the potential risks associated with tinned tomatoes, it’s essential to explore the production process. Tomatoes are typically harvested when they are ripe and then sorted according to size and quality. The sorted tomatoes are then washed, peeled, and chopped before being packed into cans or other containers. The containers are then filled with a liquid, such as water or tomato juice, and sealed. The cans are then heated to a high temperature, usually around 212°F (100°C), to kill off any bacteria and create a vacuum seal.
Linings and Coatings
One of the primary concerns surrounding tinned tomatoes is the use of linings and coatings in the cans. Many canned goods, including tinned tomatoes, are packaged in cans coated with a thin layer of epiclorohydrin-based resin or bisphenol A (BPA). These coatings are designed to prevent the can from corroding and to ensure the food remains fresh. However, BPA has been linked to various health problems, including cancer, reproductive issues, and neurological damage. While many manufacturers have started to phase out BPA-lined cans, some products may still contain this chemical.

Are tinned tomatoes poisonous due to their acidity level?
Tinned tomatoes are not poisonous due to their acidity level. The acidity in tinned tomatoes comes from the natural acidity of the tomatoes themselves, as well as any added acidity regulators like citric acid. This acidity helps to preserve the tomatoes by creating an environment that is not favorable for the growth of bacteria and other microorganisms. The acidity level in tinned tomatoes is carefully controlled to ensure that it is within safe limits for consumption.
The acidity level in tinned tomatoes is typically measured by its pH level, which is a measure of how acidic or alkaline a substance is. The pH level of tinned tomatoes is usually around 4.5-5.5, which is slightly acidic. This acidity level is completely safe for consumption and is actually beneficial in helping to preserve the tomatoes. It’s worth noting that some people may be more sensitive to acidic foods than others, and may experience discomfort or digestive issues after consuming tinned tomatoes. However, this is not due to the tomatoes being poisonous, but rather an individual intolerance to acidic foods.
Can BPA in tinned tomatoes cause health problems?
Bisphenol A (BPA) is a chemical that is sometimes used in the lining of tin cans, including those used for tinned tomatoes. There has been some concern that BPA can leach into food and cause health problems. However, the vast majority of tinned tomato manufacturers have now switched to BPA-free linings, and many countries have banned the use of BPA in food packaging altogether.
