How to preserve tomatoes: what you need to know

Ever wonder how tomatoes are preserved? Here’s what you need to know about how to preserve tomatoes for ultimate taste and quality. 

Tomatoes are undoubtedly one of the most beloved and versatile ingredients in the culinary world. Their rich flavor and nutrient profile have led to a wide array of tomato-based products, from pasta sauces to ketchup and salsa. However, the challenge lies in preserving their nutritional integrity throughout the manufacturing process. In this article, we’re examining the technology and science behind canning tomato products, and how manufacturers preserve essential nutrients to deliver wholesome products that grace our tables. 

How to preserve tomatoes

The journey from fresh tomatoes to canned tomato products involves several intricate steps. While this process is extensive, it’s important to make sure that each step is done correctly so that the products are safe and well-preserved. 

1. Selection and Harvesting: The process begins with the best-quality tomatoes at the peak of ripeness, which ensures that the tomatoes are brimming with the most nutrients and flavor.

2. Preparation: The tomatoes are sorted, washed, and often blanched to facilitate peeling and enhance the preservation process. Furthermore, the cans are preheated for sterilization, which helps ensure the cleanliness and safety of the containers. 

3. Processing Cans: Manufacturers use heat treatments to eliminate microorganisms and their spores while preserving the nutritional quality of the food. In fact, the heat applied during processing can enhance the bioavailability of certain antioxidants, such as lycopene, which becomes more accessible for absorption when cell walls are broken down during heating.

4. Cooling, Labeling, and Storage: Following processing, the cans are rapidly cooled to room temperature. Once they are cooled, the outer surface of the cans is dried for labeling, and then stored in cool and dry places before being dispatched.

Get Fired Up For USA Tomato Products

I’m here to drop some truth bombs on why spending more money on imported tomatoes from Europe doesn’t make a lick of sense when we’ve got the best damn tomatoes right here in America.

First things first, let’s talk about quality. Now, I’m not saying Europe can’t produce some decent tomatoes, but let’s be real, folks – the heart and soul of tomato growing is right here in the good ol’ US of A. It always has been. Tomatoes are native to the Americas!  Blind taste tests continue to prove that on any given day, a USA canned tomato can and usually does beat out any imports. We totally understand that most people will pick the brand their grandma used, but it’s just foolish to believe blindy that everything imported is somehow superior. Try it for yourself!   

In America, we’re all about that hustle and grind, and guess what? Supporting local farmers is part of that ethos. When you buy American tomatoes, you’re not just getting the best taste; you’re also supporting our own economy, our own farmers, and our own communities. That’s how we build a stronger foundation for our future – by putting our money where it matters most.

Let’s talk about the carbon footprint, too. Shipping tomatoes all the way from Europe? Come on, that’s like paying for a first-class ticket for unnecessary pollution. We’re all about sustainability and reducing our impact on this beautiful planet. So why not cut down on those food miles and get your tomatoes from right here in America? It’s a win-win for your taste buds and the environment.

So, to wrap it all up – we’ve got the best tomatoes, we’re supporting our own economy, we’re reducing our carbon footprint, and we’re saving time. It’s a no-brainer, my friends. Let’s keep it real and make the smart choice – go for those American tomatoes and watch your taste buds, your wallet, and the planet will thank you later. 💪🍅
