===Trial 1 - Diverging points from the original protocol===

Trial performed at FoAM Brussels Biolab on September 22nd.

   * 4 banana peels on ripening degree 7 (rather than 4)
   * Dried them in kitchen paper (instead of gauze)
   * Washed the puree (rather than the banana peels) with a 1% (rather than 0.5%) sodium metabisulphite solution
   * The color of the puree was dark yellow after blending.
   * The color turned salmon after adding HCl
   * The color turned dark olive green after adding NaOH (lessive de soude)
   * Propane 1-2-3 triol was replaced by liquid glycerin from suppositories
   * The proportions were 6 times higer than in the protocol
   * Cooked 40 minutes in the random temperature gas oven of FoAM Brussels

Ended up as a black unstructure & cooked-puree like structure (not a plastic at all).

===Trial 2===

Trial performed at FoAM Brussels Biolab on September 24th.

   * 1 banana peel, ripening degree 4
   * Dipped 10 minutes in the 1% sodium metabisulphite solution.
     * The solution stayed open to the air in the lab for 36 hours.
