=== Observations ===
 +
 +
Significant progress has been made on all tested countries.
 +

For ingredients parsing and recognition, it becomes harder and harder to get big increases in the % of known ingredients. It is expected as we have focused first on the improvements that had the biggest impact. But even a "small" increase from 83.40% to 85.55% for known ingredients in France corresponds to a drop of the unknown ingredients from 16.60% to 14.65% which is a 11.7% relative drop.

It is very interesting to see that the improvements in ingredients parsing and recognition translate in much more significant ingredients analysis (knowing the vegetarian status of a product) improvements. All countries had a 5% to 25% absolute increase of products with known vegetarian status.
