4 L tomato pulp
4 cups sugar
½ tsp cinnamon powder

3. Remove the seeds and chop the pulp into small pieces. Strain the remaining seeds thru a fine mesh screen.

  3. of course you can use the bottles if they are not damaged, and are sterilized. As for the sealing caps, you can ask DOST for sources or DTI.

  5. if you have put 2 tsp sodium benzoate (optional) it could last longer...as to its expiration, you have to experiment..by keeping the bottled catsup and checking them weekly, and until it got spoiled so you would know how long your catsup/process would last as expiration would depend on many factors like hygiene,preservatives such as sodium benzoate, materials you used etc.

    you better visit DOST and ask for help to prolong the shelf life of the catsup you have made..they would know what to do..
