Concentrated tomato puree usually contains 4% to 7% soluble solids, must be concentrated to exclude a large amount of water, in order to achieve the required product concentration of 28%. There are two methods for concentrating: the atmospheric pressure method using an opening thickener and the vacuum method using a vacuum thickener. The product quality by the vacuum concentration method is better.
Spice seasoning In order to increase the flavor, spices and condiments should be added before concentration. The proportion is 100 kg of tomato pulp sugar 15 kg, salt 2.5 kg, vinegar 3 kg, clove 0.19 kg, cinnamon 0.19 kg, pepper 0.15 kg, 0.05 kg of soybean meal and 0.3 kg of garlic.
