Wet processing includes all fleshy fruit. Tomato, eggplant, pepper, all cucurbit and any seed enveloped in a fruit. When harvesting the fleshy fruits seeds must be mature that means that different plants mature at different stages, mostly when they change to their final color. Harvest when:

  • Tomato – when ready to eat its ready for harvest.
  • Pepper – changes to its final color usually red.
  • Eggplant- losses its shin and changes color to yellow.
  • Melon – changes color, stripes appear and usually disconnects from the vine.
  • Watermelon – when ripe.
  • Cucumber – changes color usually yellow.
  • Squash – when ripe, the skin is hard and doesn’t puncture with your fingernail.

The seeds of a fruit are protected by a gelatinous coat which contains germination inhibiting compounds. Nature’s method of removing the seed’s sugar coating, Happens after the fruit falls on the soil. It then ferments and decomposes and the coating is shed. We must do the same when processing artificially.  Seeds are taken out of the fruit with their juice and left to ferment. In a way that natural yeast, bacteria and fungi can use the sugars to ferment and shed the coating of the seed.  The seeds are now washed clean, placed on a screen with air circulation to dray for a day and then bagged and transferred for a final drying in a dry room with low humidity for a few months.

The desired water content of a seed for long term storage is around 5%. High water content will shorten life span of the seed. When frozen water expands and brakes cell walls, killing the seed. With low water content of 3% and below, the seed coat will prevent water from entering the seed and germination won’t occur.

    Hey there relik, I read all the blog and saw the pics. It’s such a great mission you are taking on yourself, I am so proud, I knew we could count on you to make the world turn round. It’s so important what you are keening, I’d give almost everything to be there too. Not only to be on your side, but the thirst I have for this knowledge is great. I try doing it in my garden, but I’d need some good guidelines for success. My chickens are preparing the ground compost and I recently used their land for my winter garden, I hope it works better than my summer yard… Hehe. Good luck to you! Waiting for the next news! Bring your knowledge down to France, we miss you so!!!! Lots of love! Big sis!
