The present invention relates to a process for obtaining of disinfectant composition from grapefruit seeds. The process according to the present invention comprises the step of separating the seed and pulp of certain types of tree-ripened grapefruit from the remainder of the fruit and drying the seed and pulp for 24-48 hours at a temperature in the range of 150 DEG -200 DEG C. The seed and pulp are then tested for pesticides and only non-contaminated seed and pulp are selected for processing. The dried, non-contaminated seed and pulp is mixed at a ratio of 80:20 seed/pulp by weight. The mixture is then ground in a hammermill to small particles, whereupon the ground mixture is placed inside some type of mesh bag or perforated container which is then placed in a reaction vessel. Previously, a glycerin solution in an amount by weight approximately equal to the weight of the ground mixture has been placed in the vessel and heated to a temperature of at least approximately 150 DEG C. The vessel is sealed and the glycerin solution is then circulated through the extraction chamber and past an external ultraviolet system and magnetic system which helps to stabilize the ingredients and to remove ferrous metallic particles thereof. Glycerin circulation is continued at the same temperature for approximately 3-4 hours, whereupon the temperature is reduced to approximately 60 DEG C. while the pressure within the chamber is increased to a range of 2.500-3.000 lbs/sq. inch. There results a syrup and a residue in the reaction chamber. The syrup is then passed through a force filter system having a 300 -350 mesh nylon filter to obtain a heavy viscous lemon yellow liquid having a pH in the range of 2.5-3.0. |
