To remove excess water, vacuum vaporizers are in use. Using the vacuum system is good. It causes the condensation to be shorter. At a lower temperature. And thus the color and the rest of the appearance of the product will better preserve. This step carried out in two-way boilers. Which are in heat by steam vapor pressure. And have a capacity of about 2.5-4.5 tons.
To deliver soluble solids in brine. And to improve the taste. About 3% – 2% of salt is to the product. Add salt automatically. Sucker pumps are to the boiling pot.

Temperature process for tomato paste
This step takes place in boiling water boiler. That way cans. Immediately after reintroduction. The cans transported to a boiling pot. Depending on the cans, boiling water is under heat at 100 ° C for 80-45 minutes. And process the temperature. Cooling is done by spraying cold water. Cooling is done on the cans after removing the pot.

The half-kg cans are packed in 24 packages. And canisters of a kilogram in twelve packages of 24. And cans of a kilogram in packages of 12.
Tomato paste quality control tests
a) physical tests
1- Experiment to determine the amount of soluble solids in water or brix
Brix is important for home use. Regardless of salt. Brix should be at least 25%. Considering that 2-3% of the salt is added to the solution. The final brix is 28% -27%. so, see the price Drum Tomato paste 36-38%.
Brix tests performed by manual or desktop refractometers.
2- Examination of impurities
Tomato paste should be homogeneous. Free of impurities and dark particles. Without core and shell and fibers. It is free of odor and odor. Check the amount of impurities on a smooth tile. It casts on a white tile. And it should be press with a transparent glass plate. To create a thin layer of paste between two levels. And unwanted particles such as nuclei, shells. Particles, such as plant residues, burnt particles, etc., well defined. And they can be understood by their amount and type.
b) chemical tests
1 – PH test
The standard pH value for tomato paste is about 4.3. Measured by PH meters. Or measured by other methods.
2- Salt test using Wollard method
2.5 g of sample per 100 ml. And from that cc10. And add 0.5-1.5 milliliters of Potassium Chromate. We titrate with 0.1 normal silver nitrate. As long as its color becomes red brick. We multiply the silver nitrate consumption by 585 /. The resulting number should be between 3-2.
Preparation of Potassium Chromate Reagent
50 gr of dry potassium chromate to 100 cc.
c) Microbiological testing
Identification of bacteria and molds should be done. The product uses two serum agar (O.S.A) and (Y.G.C) agar culture media.
