Is ketchup just tomato smoothie?

Ketchup is one of the most popular condiments in the world, with 97% of households in the United States having a bottle in their fridge. But what exactly is ketchup made of? With its smooth, pourable consistency and tangy tomato flavor, some may wonder if ketchup is just a tomato smoothie. In this article, we’ll take a deep dive into the ingredients and nutrition facts of ketchup and explore whether it qualifies as a tomato smoothie or not.

Ketchup Ingredients

The primary ingredients in traditional ketchup are tomatoes, sugar, vinegar, salt, and spices. While the exact recipe and proportions vary between brands, a typical ingredient list for ketchup includes:

Ingredient Amount
Tomato Paste 75-85%
Sugar 15-25%
Vinegar 4-5%
Salt 1-2%
Spices 0.5-1.5%

As you can see, while tomatoes make up the majority of ketchup, a large portion of the condiment is also sugar. The sweetness balances out the acidity from the vinegar and gives ketchup its signature flavor profile. The spices added also vary, but commonly include onions, garlic, cinnamon, cloves, and allspice.

Tomato Smoothie Ingredients

A tomato smoothie typically contains just two main ingredients – tomatoes and optional sweeteners. Some popular tomato smoothie recipes include:

Ingredient Amount
Tomatoes 80-95%
Honey or Maple Syrup 5-20%
Salt Pinch
Black Pepper Pinch

Compared to ketchup, tomato smoothies have a much simpler ingredient list. They skip the vinegar, spices, and large amounts of added sugar found in ketchup. The tomatoes are blended smooth, with just a touch of sweetener and seasoning.

Nutrition Facts

When looking at the nutrition facts, ketchup and tomato smoothies are quite different:

Nutrient (per 100g) Ketchup Tomato Smoothie
Calories 80 32
Total Fat 0g 0.5g
Sodium 739mg 12mg
Total Carbohydrates 18g 5g
Sugars 16g 4g
Protein 1g 1.5g

Ketchup has significantly more calories, sodium, carbohydrates, and sugar compared to an unseasoned tomato smoothie. The vinegar, salt, spices, and added sweeteners bump up the numbers. Meanwhile, a tomato smoothie made of just blended fresh tomatoes contains minimal seasonings and no added sugars.


One of the biggest differences between ketchup and tomato smoothies is the texture:

  • Ketchup – Thick, smooth, and pourable. Flows easily out of the bottle.
  • Tomato Smoothie – Thinner, with a pulpy consistency. Thicker than juice but drinkable through a straw.

Ketchup achieves its signature thick, gloopy texture through cooking down the tomatoes significantly to remove water. Starch or gums like xanthan may also be added as thickeners. The ingredients are then finely pureed for a smooth consistency.

Tomato smoothies skip this cooking down process. The raw tomatoes are simply blended until smooth, leaving some of the pulp and seeds still intact. This gives tomato smoothies a thinner, pulpier texture than heavily processed ketchup.


While both ketchup and tomato smoothies are tomato-based, they have very different flavor profiles:

  • Ketchup – Sweet and tangy, with vinegary notes. Hint of spice.
  • Tomato Smoothie – Bright, vegetal tomato flavor. Savory umami notes. Less sweet.

Ketchup has a strong sweetness, acidity, and savoriness due to the sugar, vinegar, salt, and spices added during processing. Tomato smoothies let the natural flavors of the tomato shine through, with just a touch of sweetness and seasoning.


Ketchup and tomato smoothies are used in very different ways:

  • Ketchup – Primarily used as a condiment for burgers, fries, sandwiches, hot dogs, etc. Also used as an ingredient in sauces and dressings.
  • Tomato Smoothie – Enjoyed as a cold beverage. Also used in soups, sauces, and smoothie bowls as an alternative to tomato juice.

Ketchup is a classic topping squeezed onto other foods to add flavor. Tomato smoothies are drank on their own as a healthy vegetable-based drink. They can also add nutrition to blended foods and beverages.

Shelf Life

Processed ketchup lasts much longer than fresh tomato smoothies:

  • Ketchup – Unopened bottles can last up to 1 year in the pantry. Lasts 4-6 weeks after opening when refrigerated.
  • Tomato Smoothie – Lasts 2-3 days when refrigerated. Best consumed immediately after blending.

The vinegar, sugar, and sodium in ketchup act as natural preservatives allowing it to remain shelf stable before opening. Tomato smoothies made from fresh produce have a much shorter shelf life.


While ketchup and tomato smoothies both contain tomatoes as the base ingredient, they have significant differences when it comes to ingredients, nutrition, texture, flavor, uses, and shelf life. Ketchup goes through extensive cooking and processing, losing much of the original vegetable flavor. Tomato smoothies retain the fresh tomato taste by blending the raw produce into drinkable form.

So is ketchup just a tomato smoothie? Although ketchup uses tomatoes as its main ingredient, the added sweeteners, vinegar, spices, and processing make it a condiment rather than a vegetable-based drink. A tomato smoothie better fits the profile of blended raw produce, without the tangy zip of ketchup. Next time you reach for the ketchup, consider making your own fresh tomato smoothie instead for a lighter take on the tomato!
