Naturally, plant ingredients are not the only source of food and drinks. Actually, in advanced developed countries, food from animal source is dominating where milk and meat represent the most concrete examples of drink and food, respectively. Nevertheless, the prevalence of specific applications, such as protein components useful for human health, stimulates the development of plant consumption. As a counterpart, plants also contain threatening protein components (toxins and allergens) that require attention for an improved food security therefore, there is a need of detecting low-abundance proteins (the deep proteome) from plant tissues as schematically illustrated in Figure 1. It is within this context that this chapter purposely limits the discussion to plant proteomics. The description about the situation of low-abundance animal-derived food proteomics has been made by the same authors in various other documents (3-6).

For the expression of recombinant food allergens, the genomic- or cDNA-derived clone is ligated into a vector and introduced into the host organism. Bacteria, yeast, plants, and mammalian cells can be host systems.
