INTEGRATED PRODUCTION OF PHYTOCHEMICAL RICH PLANT PRODUCTS OR ISOLATES FROM GREEN VEGETATION
First Claim
1. A composition comprising at least one phytochemical ingredient, the said phytochemical ingredient being obtained by a process of fractionation of at least one green plant material derived from dried or fresh green crop, green crop fractions or dried algae;
- the said green crop being at least one selected from the group comprising a green leafy vegetable, a green forage/fodder, a green leafy vegetation of a grain crop, a green leafy vegetation of a pulse crop including beans, a green leafy vegetation of an oilseed crop, a green leafy by-product vegetation of a root and tuber crop or a cole crop, green leafy vegetation of tobacco; and
the said process of fractionation comprising any one or a combination of following steps;
a. extracting the said green plant material by contacting with at least one oil, preferably an edible oil, with or without heating, separating the oil extract and the residue,b. extracting the said green plant material, for a period of time, with or without heating, by contacting with an alkali or an acid under conditions that may or may not result in partial degradation of proteins, neutralizing and separating the liquid extract fraction and the residue fraction as products with or without further treatment, modification or further fractionation,c. further fractionating or modifying a primary fraction obtained in a process of green crop fractionation or a sub-fraction of the said primary fraction;
the said primary fraction being a product of a green crop fractionation process comprising steps of comminuting the fresh green plant material, separating a moist fibrous fraction as one primary fraction from the juice as another primary fraction and treating juice fraction to separate a primary water soluble deproteinized juice fraction that is high in water content from a primary water insoluble high protein low fiber fraction;
the said—
further fractionation excluding (i) extracting the said water insoluble high protein low fiber fraction by a volatile organic solvent, (ii) use of polypropylene glycol in the extraction, (iii) degradation products and enzymatic rearrangement products of the said insoluble high protein low fiber fraction, and (iv) use of supercritical extraction.

Abstract
Invention provides improvement in process of green crop fractionation to provide a route for production of novel phytochemical compositions or ingredients containing natural products contained in green plant material. Primary products of green crop fractionation produced in conventional process are fractionated further by using processes of oil extraction, aqueous acid extraction, aqueous alkali extraction, solvent extraction or are modified further in their form leading to products that are enriched in either oil soluble phytochemicals or water soluble phytochemicals. Most of these products can be used for human consumption directly or as an ingredient of a composition with a minimal further processing. Choice exists of using a process that totally avoids use of volatile organic solvents.
