How To Peel Your Tomatoes
To peel, make a small 'x' on the bottom of each tomato, then drop them into boiling water for about a minute.
Once the skin starts to split, remove them from the water and the skin should easily peel off. For straining, press the cooked tomatoes through a sieve or food mill to separate the seeds and skin from the juice and pulp.
Sealing The Lid Correctly
Preparing your jars before starting is essential to prevent bacteria growth. To sterilize jars, wash them in soapy water, then boil for 5 minutes. After filling the jars, wipe the top and rim, and screw on the lid.

🍅 Production Process of Canned Tomatoes
🥫 Harvesting Ripe Tomatoes
The first step is to harvest ripe tomatoes from the fields. These tomatoes are carefully selected based on their color, size, and ripeness. Farmers ensure that only the best tomatoes are chosen for canning to guarantee a delicious end product.
🥫 Sorting and Washing
Once the ripe tomatoes have been harvested, they undergo a sorting process. This involves removing any damaged or spoiled tomatoes that may affect the overall quality of the canned product.
After sorting, the tomatoes are thoroughly washed to eliminate any dirt or impurities that may be present on their surface.
🥫 Blanching and Peeling
After washing, the tomatoes go through a blanching process. They are briefly immersed in boiling water to loosen their skins. This step makes it easier to remove the later on and helps maintain the freshness of the fruit.
Once blanched, the tomatoes are quickly cooled down in cold water.
Next comes peeling - an essential part. The blanched tomatoes now have loose skins that can be easily removed by hand or using specialized machinery. By removing, we ensure a smoother texture.
🥫 Crushing and Straining
After peeling, the whole tomatoes are crushed into smaller pieces or pureed, depending on their intended use. Some recipes call for diced or crushed tomatoes, while others prefer a smooth consistency like tomato sauce or puree.
The crushed or pureed mixture then goes through to remove any remaining seeds or solid pieces. This step ensures that our creation have a uniform texture without any unwanted bits.
🥫 Filling and Sealing
Now that our tomato mixture has been cooked to perfection, it is time for filling and sealing. The hot tomato product is carefully poured into sterilized cans, leaving an appropriate headspace to allow for expansion during processing. The cans are then sealed tightly using lids or caps to ensure secure packaging.
🥫 Processing and Sterilization
To guarantee food safety and extend shelf life, canned tomatoes undergo a process known as sterilization. This involves placing the sealed cans in pressure cookers or retorts filled with boiling water.
The cans are heated at high temperatures for a specific duration, effectively killing any bacteria or microorganisms that could cause spoilage.
🥫 Cooling and Storage
After processing, the cans of diced tomatoes are removed from the pressure cookers and cooled down rapidly. This rapid cooling helps maintain the quality of the product by preventing overcooking or loss of flavor.
Once cooled, label and pack into cartons or cases for storage and distribution. They are stored in cool, dry cellars or warehouses until they reach consumers' hands.
🙋 Why Should I Choose Canned Tomatoes Over Fresh Ones?
Tomato Flavor In Canned Versus Fresh
Tomato flavor can vary drastically between fresh and canned. Interestingly, canned whole tomatoes often hold a rich tomato flavor, sometimes even more satisfying than their fresh counterparts.
This is because canned tomatoes are tomatoes that have been picked at their peak ripeness and quickly canned, retaining their flavor.
Convenience of Canned Whole Tomatoes
Unlike raw tomatoes, they are pre-peeled and ready to use straight from the can. For dishes requiring the flavor of the tomatoes without their skin, canned whole tomatoes are a great choice, saving you the hassle of peeling.
Cost-Effective Choice: Store-Bought or Homemade?
When it comes to cost-effectiveness, it's a bit of a toss-up. Fresh tomatoes can easily become expensive outside of their growing season, making canned tomatoes a cost-effective choice, whether store-bought or homemade.
