What Is Tomato Paste?

Aseptic Tomato Paste is a thick and concentrated mixture prepared from fresh tomatoes. To make tomato paste simply, smashed tomatoes are cooked for hours, then their seeds and skin are filtered, then the remaining liquid is cooked for a longer time to make a thick paste. Tomato paste has many fans all over the world who add it as a seasoning and sauce to their various dishes. If in the processing line, all procedures are done according to the standards, the paste will be sufficiently thick, with its natural taste and color. It will also retain the properties of tomatoes, such as minerals and vitamin C.

Tomato Paste Production Line

The method of producing tomato paste in most factories is almost the same. The steps of tomato paste production include:

  1. Selection and sorting: The first step for the production of tomato paste is the selection of tomatoes. Ripe and healthy tomatoes are selected and sorted from other tomatoes.
  2. Washing and drying:  Chosen tomatoes are washed carefully by cleaning machines. Then they are air-dried.
  3. Crushing: After washing and drying, the tomatoes are transferred to a tomato crusher to be crushed into 3-5 mm particles. After that, the crushed tomatoes are transferred to a mixer to be crushed and chopped more until smooth.
  4. Cool or Hot Break: Tomato paste is preheated to 65-75°C for Cool break (CH) processing or to 85-95°C for Hot break (HB) processing both for 10-15 minutes. HB paste is commonly used for ketchup and ketchup varieties including 28-30° aseptic tomato paste, while CH paste is used for concentrate paste at aseptic tomato paste brix 36-38° Brix.
  5. Removing water: In this stage, the tomato pulp, which includes the fiber of tomato, juice, and seeds, is sieved through a purifier. Consequently, tomato paste becomes smoother and softer. Normally, 95% of the tomato paste passes through two sieves. And the remaining five percent, which consists of seed fiber and tomato skin, is considered waste.
  6. Evaporation: The evaporation stage is the most important stage of the tomato paste production process. The tomato paste juice evaporates until the paste reaches the desired concentration and density that increases continuously. The complete process of concentration and evaporation is in vacuum conditions at a temperature of less than 100°C.
  7.  Aseptic filling: Tomato paste is transported directly to the aseptic container, then transferred through the sterilizer cooler in pre-sterilized packages. After packaging, the concentrate can be stored for up to two years.

In some factories, tomato paste is packed in non-aseptic conditions. In this case, after packaging, the tomato paste must go through another step for pasteurization. The tomato paste is heated for pasteurization, then before delivery to the customer, it will be controlled for two weeks under certain conditions.
