Did you know that each tomato can have up to a hundred seeds?

Make sure to wash up your tomato before cutting into it.

Once cut, use a spoon to scoop the seeds from the cavity.

You will notice that the seeds are coated with a gel and pulp.

  • Separating seeds from gel

After three days, fill the jar with water and let the seeds settle at the bottom.

If you ever wondered how to separate tomato seeds, it's that simple.

Now, pour out the water along with the tomato pulp.

Any seeds that float are not viable.

  • Rinsing and straining seeds

Repeat the process until the water draining out is clear.

  • Proper drying process

Finally, pour the seeds onto a filter, letting excess water drain.

Place the seeds on a paper plate or newspaper to dry in a well-ventilated area for several days.

The next step is storing your seeds in a container or bag in a dark, cool, dry place.

Label your containers.

Glass jars or plastic wraps are ideal because they will not let water or moisture get to your precious seeds.

Keep the seeds away from direct sunlight.

In addition, ensure your seeds are always dry because any water contact can lead to the seeds' germination or even a mould contaminating the batch.
