Pulp Making and Preservation

We have to make tomato pulp and then to preserve it using preservatives like sodium/ potassium meta bisulphite and preservative techniques and then different analysis are performed on weekly basis. We choose tomato for pulp making.


The whole procedure followed is as:

Equipment required:
  • Peeler
  • Stainless steel saucepan
  • Wooden spoons
  • Knives (stainless steel)
  • Cutting boards
  • Grinders
  • Fridge
  • tomato
  • Potassium metabisulphite
  • Take 500g tomato.
  • Washing and cleaning is done.
  • Then give hot water treatment for convenient peeling.
  • After peeling, grind the tomato in grinder.
  • Filter the paste to remove seeds.
  • After pulp formation add preservative (sodium meta bisulphite) to its permissible limit .
  • Then pour the pulp in sterile bottles using hot filling and seal them with wax.

And store it in two condition refrigerated

Analysis (1st week) :

Titratable acidity 8.3
Brix 2
PH 4.4
Specific gravity 1.04

Analysis(2ND Week):

Titratable acidity 8.5
Brix 1.5
PH 4.6
Specific gravity 1.07

Strawberry Nectar Preparation:
