Manufacturing Process of 70g Canned Tomato Paste The production of 70g canned tomato paste involves a series of carefully controlled steps to ensure quality, safety, and shelf stability. The process begins with the selection of ripe, high-quality tomatoes, which are thoroughly washed to remove dirt, debris, and any residual pesticides. The tomatoes are then sorted to eliminate damaged or unripe fruits, ensuring only the best raw materials are used. After sorting, the tomatoes are crushed and heated to break down cell walls, releasing juices and pulp. This mixture undergoes a refining process to remove seeds, skins, and fibrous materials, resulting in a smooth tomato puree. The puree is then concentrated through evaporation, where excess water is removed under controlled temperatures to achieve the desired thickness and brix level (a measure of sugar content and density). This step is critical in determining the final consistency and flavor intensity of the tomato paste. Once the desired concentration is reached, the paste is homogenized to ensure uniform texture. It is then heated again for pasteurization, eliminating harmful microorganisms and enzymes that could spoil the product. The hot paste is immediately filled into pre-sterilized 70g cans, which are typically made of tinplate or aluminum to prevent corrosion and maintain freshness. The cans are sealed hermetically to create an airtight environment, preventing contamination and oxidation. After sealing, the cans undergo a final sterilization process in retorts (high-pressure steam chambers) to ensure commercial sterility. This step extends shelf life without the need for preservatives. Once cooled, the cans are labeled, coded with production dates, and packed into cartons for distribution. Quality Control & Standards Throughout production, strict quality checks are implemented, including pH monitoring, brix testing, and microbiological analysis. The final product must meet international food safety standards such as ISO, HACCP, and FDA regulations. The 70g portion is convenient for household and commercial use, offering a long shelf life (typically 2–3 years) when stored in a cool, dry place. Advantages of Canned Tomato Paste Canned tomato paste retains rich flavor, vibrant color, and nutritional value, including lycopene, an antioxidant. The small 70g size reduces waste and ensures portion control. The airtight packaging also eliminates the need for refrigeration before opening, making it a practical pantry staple. By adhering to rigorous manufacturing protocols, producers deliver a consistent, high-quality product that meets global consumer demands for convenience and taste.
