<p>1528783 Extracting protein from leafy vegetable matter FRANCE LUZERNE 30 Oct 1975 [4 Nov 1974] 44959/75 Heading C3H A cyclic process for treating leafy green vegetable matter (e.g. alfalfa) to recover separately the insoluble (protein) and liquid matter in cake and syrup form comprises (1) mixing a first quantity of the leafy matter with a predetermined quantity of a reheated previously produced serum, the quantity of serum being sufficiently large relative to the amount of leafy matter to provide a liquid treatment medium for the leafy matter, the temperature of the serum being sufficiently high to flocculate the protein content, the duration of contact with the serum being sufficiently long to macerate the leafy matter, (2) separating a sufficient proportion of the serum from the macerated leafy matter to form a cake having a dry solids content of 35-60 wt. per cent and at least one serum effluent; (3) drying the cake; (4) reheating at least a part of the serum effluent to at least the protein flocculating and macerating temperature; (5) recycling the reheated serum to a succeeding quantity of the leafy at the above-stated temperature and in the above-stated amounts to start a further cycle of the process and (6) concentrating the remaining part of the serum effluent to syrup viscosity.</p> |
