Besides a number of minor changes made with the aim of improving definitions and/or descriptions the following important changes are introduced.
Citrus fruits. Kumquats are transferred from this group to “Assorted tropical and sub-tropical fruit - edible peel” because the fruit is small compared with the other citrus fruits and because, unlike the latter, the whole fruit is consumed, including the peel.
Fruiting vegetables. Instead of “Fruiting vegetables - edible peel” and “ - inedible peel”, the groups proposed now are “Fruiting vegetables, Cucurbits” and “Fruiting vegetables, other than Cucurbits”. Many species of the latter group belong to the botanical family Solanaceae. The reason for the change is that the borders between the former groups are not clear-cut. Some of the Cucurbit species are consumed at an immature stage whole, including the peel, whereas at a more mature stage of the fruit the peel may be discarded.
The old “Brassica leafy vegetables” group is now split into two since the original single group is much too broad from the standpoint of similarity in residues. It has to be considered rather illogical if commodities such as mustard greens with a high surface area: weight ratio are classified in the same group as the heavy weight, small surface area head cabbages and flowerhead cabbages (e.g. cauliflower). The latter commodities are also often protected from pesticides by outer leaves, which are discarded before the product is marketed. The true leafy Brassicas are transferred to the “Leafy vegetables”, e.g. mustard greens, turnip greens, kale, including curly kale, Chinese cabbage and related species etc., which show a similar residue pattern. A separate group is made for the head cabbages (often called cole crops) such as red, green and white cabbage, cauliflower, broccoli.
To avoid the uncertainties which often exist with regard to commodity names and descriptions in the legume vegetables group, the old group is divided into two groups: 1. “Legume vegetables”, which includes immature seeds, whether consumed with pods or not, and the naturally or artificially dried, mature seeds which always move in trade without pods. The latter commodities, which are often exposed to post-harvest treatments, are brought together in the separate group “Pulses”.
