Terrestrial biomass is of course dependent on a non renewable resource - the soil - for mechanical support and the supply and transport of nutrients to the growing plant. The Canadian total land area of 996,6991000 ha has the following land classification (4). 

QS, like those of other plants, store proteins in the embryo to provide nutrients for growth and development (Herman and Larkins, 1999). In the food area, proteins stored in seeds are the source of the proteins consumed directly as food by humans (Shewry et al., 1995). Stored proteins provide building blocks for rapid growth upon seed and pollen germination (Herman and Larkins, 1999). Osborne (1924) introduced a classification of plant proteins based on their solubility in a series of solvents, such as albumins in water, and globulins in saline. 

In accordance with modern classification, the trace elements are those with content in the Earth (darks) about 1 x 10 % or less. Many trace elements are important elements in the biogeochemistry of any terrestrial or aquatic ecosystem and some of them are required micro-nutrients for plant, human, or animal life (Figure 1). 

NSP, by definition, includes all the plant polysaccharides other than starch. For the reasons given above, NSP are divided into two broad classes in the classification and measurement scheme described here (Table 1) (1) the cell-wall NSP, which impart rigidity, and encapsulate and control the release of other nutrients, and (2) other NSP, including gums and refined preparations of cell-wall material, which occur in foods mainly as additives. There is no endogenous human enzyme for the hydrolysis of NSP, which are therefore nonglycemic, and all become available for fermentation in the large intestine. 

NATURAL FOOD COLORS. Colors abound in the plant and animal kingdom which can be used for coloring foods. None of these require batch certification. Some are nutrients in their own right, others are spices, and still others fall under the general classification of carotenoids a product of which nature makes about 400 million lb (180 million kg) annually. Table C-20 lists most of the more common approv naturallyoccurring color compounds, and indicates their source and use.
