In general, nonconventional protein foods must be competitive with conventional plant and animal protein sources on the bases of cost delivered to the consumer, nutritional value to humans or animals, functional value in foods, sensory quality, and social and cultural acceptability. Also, requirements of regulatory agencies in different countries for freedom from toxins or toxic residues in single-cell protein products, toxic glycosides in leaf protein products, pathogenic microorganisms, heavy metals and toxins in fish protein concentrates, or inhibitory or toxic peptide components in synthetic peptides must be met before new nonconventional food or feed protein products can be marketed.

The solubility of P-carotene in supercritical fluids has been studied extensively [81 to 85], The extraction of P-carotene from a wide varieties of natural sources has also been described like alfalfa-leaf protein concentrates [86], carrots [34,87], sweet potatoes [88], and algae [89],... 

Less Conventional Sources of Protein. In addition (o the traditional animal sources of protein already described and the very large amounts of vegetable protein derived from the soybean, other sources of protein on a large scale for the future are under intense study. Among these are (1) oilseed crops, such as rapeseed and cottonseed (2) leaf proteins (3) algae and (4) single-cell protein. 

There are large resources of potential food proteins (oilseed, yeast, leaf) which are presently unexploited. With the application of innovative scientific and technological methods these can become significant sources of food protein. In developing ingredient protein from plant sources, research emphasis must include studies to determine the physicochemical or functional properties of these proteins. 

On a qualitative and quantitative basis, baobab leaf appears to be a good source of protein for those populations for whom this plant material is a staple (2). The amino acid profile has been previously reviewed (2, 6, 7, 58). Because Nordeide et al. (6) showed results in units (mg of amino acid/g N) that differ from those found by other researchers (2, 7) (mg of amino acid/g dry weight), these data are not compared to each other in this review. Nordeide et al. (6) concluded that baobab leaves are potentially protein sources to be used to complement the amino acid profile to improve the overall protein quality of the local diet. Baobab leaf contains 10.6% protein on a dry weight basis and significant amounts of all the common amino acids (Table Xll) (2). 

Leaf protein is a valuable and renewable source of protein. It has been extensively investigated as a possible solution for world hunger, protein deficiency and starvation. Of the... 

Leaves and subterranean plant organs are additional sources of protein materials. Potato proteins are largely available as a by-product of the starch extraction. A promising source of soluble proteins is represented by the leaves of many species leaves contain about 80-90% water and 10-20% organic material, a small part of this (10-30%) is made of proteins. About 50% of the proteins are water soluble and can be extracted and purified as a crystalline protein fraction with a molecular weight in the range 10-60 kDa, suitable for food and cosmetic purposes (leaf protein concentrate) (18). 

Alfalfa leaf protein concentrates (LPC) have been shown to be excellent sources of amino acids (Blckoff al., 1975) and other nutrients for swine (Cheeke, 1974 Cheeke et al., 1977a Cheeke and Myer, 1973) and poultry (Kuzmlcky and Kohler, 1977) and potentially for human consumption. However, the possible concentration of naturally occurring biologically active compounds In alfalfa sprouts and leafy protein concentrates makes It essential to develop procedures for minimizing such compounds during... 

Isolating protein from plant leaves may provide a protein source which could be used as a complementary protein in countries where it is too rainy to dry seed crops. Green leaves are among the best sources of protein. By pressing the leaves, a protein-containing juice can b>e obtained which may b>e coagulated and dried forming a product that is 50% protein. This product is called leaf protein concentrate (LPC). 

Others. Alfalfa meal is used extensively as a poultiy and cattle feed and as a source of raw material for the manufacture of leaf protein intended for human consumption. Alfalfa is also a source of chlorophyll manufacture. 

Plant tissue collection for DNA and protein studies has primarily utilized leaf tissue, but seeds, roots, flowers, stems, pollen, spores, and game-tophytes have all been used successfully. For example, DNA extraction from the parasitic Cuscuta required using only intemode tissue to prevent DNA contamination from its host species26 likewise, the green stems of a leafless Koeberlinia provided an adequate source of DNA.27...
