Phyto-nutrients

Some studies have found a higher content of dry matter, minerals, vitamins and flavour-providing phyto-nutrients in organic products, especially in green vegetables, and a lower concentration of potentially harmful nitrate. Other studies have been unable to confirm this, however.

Whatever constraints exist on the biogeochemical composition of phyto-plankters, uptake abilities ought to be potentially more variable. It should be possible for the transport sites for one nutrient in the cell wall to be increased at the expense of sites for other nutrients. However, this does not seem to occur in the case of iron (Sunda Huntsman, 1995), perhaps because of...

In food processing, the major objectives are sometimes achieved at the expense of some loss of recognised nutrients. However, in other cases, important nutrients may become available only after appropriate processing, since inhibitors or other interfering compounds may be destroyed or inactivated. Toxic factors can sometimes be destroyed by denaturation, as with enzymes, protease inhibitors and phyto-haemagglutinins. They can also be physically removed, for example by leaching, solvent extraction or solid classification methods, as in the removal of gossypol from cottonseed protein, or of phytate from cereals.
