At our laboratory we have studied the distribution of the biologically active saponlns during the preparaton of LPC by two different processes In one process (Pro-Xan process) the soluble and Insoluble proteins are precipitated together (whole LPC) to provide a chlorophyll-pigmented protein concentrate In the second process (the Pro-Xan II Process) both a chlorophyll-pigmented (green LPC) and a white protein (white LPC) concentrate are prepared separately (de Fremery e al, 1973 Edward al 1975) ... 

The wide distribution of chlorophylls throughout the plant kingdom facilitates the scrutiny of chlorophyll-rich vegetables for human nutrition with a view to their direct consumption. However, until now, little standardized information was available in the literature regarding the absolute total chlorophyll contents and the ratios of chlorophylls a and b in raw materials. The different analytical methods of extraction and quantification and the lack of data about moisture contents (that may vary considerably among varieties and preparations) can also influence the final contents of pigments. These factors have largely contributed to the discrepancies found in similar food samples.
