Nutritional and taste quality of harvests

The primary criterion for the selection of natural seeds

The quality targeted concerns the harvests themselves: fruits, leaves, roots, tubers, grains and other edible parts produced. It does not primarily concern recipes or culinary transformation.

01

What is evaluated

The evaluation concerns the part actually consumed of a plant cultivated in a given territory, at a specified harvest stage, under described conditions.

  • Fruits, leaves, roots, tubers, grains and other edible parts produced.
  • Harvest stage, growing conditions, soil, water, climate and season.
  • Seed traceability: provenance, varietal identity, reproducibility.

Cooking and transformation come afterward. They can reveal a quality; they do not produce it.

Order of criteria

RankCriterionWhat it requires
1Nutritional qualityThe actual food contribution of the harvest, established by analysis before any strong claim.
2Taste qualityThe taste of the harvest, assessed in a described and comparable context.
3Natural, reproducible seedA natural seed, resown and multiplied without a purchase imposed at each cycle.
4Territorial adaptationBehavior observed under local conditions, over several seasons.
5Local reproductionThe capacity to produce true-to-type and viable seeds on site.
6Genetic and food diversityThe widening of a territory's food resources, without uniformization.
7Ecological and territorial consequencesEffects on soils, water, present species and the territory's balances.

Yield, size, appearance and aptitude for commercial storage demonstrate no nutritional or taste quality.

Ten-step evaluation protocol

  1. Documented preselection: inventory of candidates and sources consulted.
  2. Botanical, varietal and geographic identity: precisely naming what is being studied.
  3. Provenance and reproducibility: verifying the origin and reproducible nature of the seed.
  4. Comparative cultivation: growing several candidates under described and comparable conditions.
  5. Observation of the harvest: parts produced, quantities, regularity, defects observed.
  6. Contextualized tasting: taste assessed at the specified stage and under the specified conditions.
  7. Nutritional analysis before any strong claim: no claim without measurement.
  8. Reproduction over several cycles: verifying the stability of observations over time.
  9. Publication of limitations: uncertainties, failures, biases and scope of validity.
  10. Decision: continue, correct or abandon, with a written reason.

This protocol describes a method to be applied. No step has yet been carried out: no data, no result and no experiment are presented.

What it is forbidden to claim

No harvest is declared "better", "more nutritious" or "adapted" without an established comparison, a described method, a specified territory and an indicated level of proof.

  • No superlative without a named comparison.
  • No nutritional claim without analysis.
  • No claim of adaptation without several seasons observed.
  • No result announced before having been produced and published with its limitations.
