Abstract
Gelatinous polysaccharides are obtained by irradicating precursor-containing material with ionizing penetrating radiation and extracting said polysaccharide from the irradiated precursor material. Typical of the polysaccharides are acacia, karaya, tragacanth, agar-agar, locust kermel and locust bean gums, pectin and alginic acid. The naturally occurring precursor materials include various plants and trees, and exudates therefrom, seaweeds, seeds, fruit and vegetables and their extracts. These materials may be treated in any form but are preferably irradiated in substantially dry form. The radiation employed includes beta rays, cathode rays, gamma rays, e.g. cobalt-60 and X-rays and may have an energy up to about 15 Mev., preferably 10-3 Mev. up to 4,0 Mev. The irradiation may be effected by passing the material through the radiation beam at distances of the order of 1 inch to 18 inches for periods ranging from 5 secs. up to 8 hours. The preferred dosage range is 0,5 to 4,0 X 106 R.E.R. The precursor material is then extracted by known method to obtain the polysaccharide. Examples of the irradiation of oranges and seaweed with cobalt 60 before extraction of pectin and alginic acid, respectively, are given.
