A bush that grows in marshy areas of the American continent unexpectedly demonstrated a potential source of food, also capable of growing in soil with high salilinty. According to the FAO more than 700 million hectares of land in the world are 'poisoned' by salt or other compounds of Sodium. In the case of cultivated land, the problem is often created by the cultivators who irrigate their fields with poor quality water rich in salt. In an effort to render these areas again productive, researchers are trying to develop new varieties of plants and vegetables that can survive high salinity levels. The description of the plant in question is Salsola kali (saltwort) is published in the magazine "Food Research International" (amprango@foodsci.uoguelph.ca , www.sciencedirect.com). It's cultivation could represent an optimum cultivation for all salty areas. The plant reaches a height of 2m and the analysis of its seeds (size of a pepper grain) made at the University of Guelph, Ontario, Canada, reveals the seeds to be rich in protein, oils and amides. Proteins account for 17% of the weight of the seed, the oil is practically the same as that of sun-flower (Helianthus) and can be used for cooking and in the production of margarine. The starches account for 50% by weight of the seed and could be used for purposes other than nutrition, for example for cospetics industry or in the manufacture of biodegradable plastics.
