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

   * 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
