If the category cleanup worked well, it should be possible to define good average nutritional values for products in this category. But before we can do that it is necessary to clean up the data and remove all obvious errors.

Apple juices hardly contain any salt. The median value is 8 mg per 100 ml.

As can be seen in the graph, there are a lot of products with a salt level over 200 mg/100 ml. Unfortunately many of these are products that indicate an upper limit, like < 1 g. This is not very informative. The producer probably did not bother to do a real measurement. The same goes for the value of zero, which is also very frequent. Ideally I filter out the zero entries and the less than entries. (I do not know how to de the latter).
