Tomato sauce and tomato ketchup are popular condiments all over the world. Clean, wholesome tomatoes of intense red colour and of meaty, not watery texture are used for sauce making. High acidity and a rich tomato flavour are additional desirable qualities.
Sound tomatoes are washed very thoroughly, cored, sliced, heat crushed and pulped (through a pulper or juice extractor) to remove seeds and skins. Tomato pulp or paste is then cooked with the requisite quantities of spices, onions, garlic, sugar, salt and vinegar.
The whole mass is concentrated to a final TSS (Total Soluble Solids) of more than 25 per cent. The mass is finally passed through the finisher and filled into clean, dry bottles.
Bottles are cleaned, labelled and packaged for marketing. (Preservation is assured either by use of preservatives or by pasteurization).
