Abstract

1516208 Decaffeination processes SOC DES PRODUITS NESTLE SA 7 Nov 1975 [27 Nov 1974 18 Aug 1975] 46175/75 Heading A2B Vegetable materials, especially tea and coffee, are decaffeinated by contacting the materials, themselves or aqueous extracts thereof, with a liquid, water-immiscible fatty material. When an aqueous extract of tea or roast coffee beans is treated, volatiles may be removed before contacting with the fatty material and recombined with the extract after removal of caffeine. When an extract of green coffee beans is treated, it may be recycled for further contact with the beans after contact with the fatty material. The aqueous extract may have a solids content of 2-60% and the contacting temperature may be 0-50‹C. When coffee beans are contacted directly they may have a moisture content of 20-60% and contacting is at 30-150‹C. The fatty material should contain an equilibrium moisture content, e.g. 0.9-1.2%. Contacting may be performed in a multistage counter-current process. The fatty material may be sunflower, soy bean, corn, peanut or coffee oil, triolein or lard. [GB1516208A]
