V. Ncderlandschc Linolenrafabriek) 23. Germ-free liquid food. Hollandsche Osano N. V. Dutch 52,998, Aug. 15, 1942. Milk and cream are steril ized by removing gases therefrom and pressing in pure oxygen, then heating under an Oj pressure of more than 2 atm. abs. for 1-8 hrs. at 50-65, and cooling under the same Oj pressure. A. J. C. van de Waal Food product from starch. N. V. W. A. Scholtcn's Chemische Fabrieken. Dutch 52,875, July 15, 1942. Starch from potatoes, sago, or manioc is mixed with at least 5% protein_(milk powder) and 100% water at most and converted into cold-water paste. Dutch 53,346, Oct. 15, 1942. Starch is mixed with protein, water, and an acid, gelatinized, and flaked. Ninety kg. potato starch, 10 kg. skim-milk powder, 85 1. water at 00, and 0.5 kg. salt are acidified by phosphoric acid to pH 6 and gelati nized. A. J. C. $an de Waal Food-conditioning composition for use in refrigerators. Mortimer J. Stammelman. U.S. 2,417,889, Mar. 25, 1947. Drying, shrinkage, and interchange of odors of foods kept under refrigeration may be inhibited by the use of a 3 to 6% soln. of AcOH absorbed in a mixt. of 4 parts plaster of Paris and one part diatomaeeous earth. Addnl. AcOH may be added as required to replace that- which evaporates. ' E. O. Whittier Improving grain. Wessanen's Koninklijke Fabrieken N. V. Dutch 53,085, Sept. 15, 1912. Grain is treated some minutes at reduced pressure with sulfur dioxide and steam simultaneously at 40-85 for sterilizing and bleach ing. A. J. C. van de Waal Conditioning grain before milling. Wessanen's Koniu- klijke Fabrieken N. V. Dutch 53,149, Sept. 15, 1942. Steam at a pressure of less than 1 atm. and a temp, of 35-' 55 is led through the grain for 1-2 hrs.; this renders the husks somewhat moist and prevents their being ground too fine. Cf. C.A. 36, 42167. A. J. C. van de Waal Device for testing the sediment content of milk and the e like. Bernard L. Kinyon. U.S. 2,414,044, Jan. 7, 1947. A portable, power-operated sediment tester is described. M. L. H. Solid sugared milk products containing reducing sugar. N. V. Nederlandsche Gruydre-Blokmelkfabrick. Dutch 52,316, April 15, 1942. Milk, partially creamed milk, or cream with sugar is condensed in a vacuum to a paste after having dissolved in it glucose or other reducing agent of a reduction-oxidation potential of about 30-50 mv. in sufficient quantity to eliminate oxidation of milkfat (1 part of glucose in 3 parts of milkfat). The reducing sub stance is only a part of the sugar content (40-50%). The water content is 6-15% (preferably 8-12%). Oats, pudding powder, etc., can be added. A. J, C. van de Waal Dehydrator for milk, fruit juices, and the like. William H. Taylor. U.S. 2,414,215, Jan. 14, 1947. M. L. H. Use of sodium diacetate to retard or inhibit the growth of microSrganisms in meat. Hans F. Bauer and Elmer F. Glabe (to Stein, Hall & Co., Inc.). U.S. 2,417,806, Mar. 25, 1947. An acetate contg. combined but undissoed. AcOH in its mol., such as (A c0N a),.(A c0H )2.H20 , may be mixed with a meat product or applied to its surface to inhibit the growth of molds or bacteria. The acetate may be mixed with edible adhesives or binders prior to use. Rxpts. are described which indicate that 0.35% of Na di acetate is sufficient to inhibit the growth of bacteria and molds for 72 hours. Cf. C.A. 41, 1355a, 2510-L _ E. O. Whittier Concentrating aqueous dispersions with the use of vegetable material. Algemeene Vereeniging van Rubber- planters ter Oostkust van Sumatra. Dutch 55,653, Dec. 15, 1943. Latex or milk can be coned, by contact with dry vegetable material that absorbs water. E.g. 100 cc. -milk was treated with resp. 20, 30, 40 g. soybeans. The dry contents rose from 13.62% to 17.85, 21.07, and 25.05%. A. J. C. van de Waal Control of moisture content in dried foods by precooking. Robert M. SehafTncr (to Guardite Corp.). U.S. 2, 417,843, Mar. 25, 1947. The higher the temp, of pre cooking a food prodifet, the lower will be the water content of the product after undergoing a predetd. drying cycle. Damage to the structure of the product is the limiting fac tor detg. the temp. used. A max. temp, of 229F. for about 2 min. is suggested for cooking potatoes prior to drying. E. O. Whittier Dry potato product. N. V. Machinefabriek Reineveld. Dutch 53,342, Oct. 15, 1912. Heating the potato cut tings is combined with treating them with aldehydes, e.g. 50-2000 g. butyraldehyde for 100 kg. cooked potatoes (just underdone). It is intended as a supplement to bread dough. A. J. C. van de Waal Portable food dehydrator. Wright W. Gary (to Filtrol Corp.). U.S. 2,414,642, Jan. 21, 1947. The app. is charged with a desiccant, such as silica gel, anhyd. char coal, activated alumina, bauxite, anhyd. CaSO, diato- maceous earth, C black impregnated with CaClj or other water-adsorbing medium. This desiccant is carefully dried to about 5-8% moisture. The vegetables or other food to l>c dehydrated are placed below the diaphragm contg. the desiccant. The dehydrator may be placed in the oven of a cookstove set at 100-20F. or else connected to a vacuum recirculation pump. M. L. Hoseh Protein-saving fodder. De Nederlandsche Centrale Otganisatic voor toegcpast-natuurwetenschappelijk On- derzoek. Dutch 57,070, March 15, 1946. Sugar-contg. fodder is sepd. into saccharine juice and pulp. The juice is fermented by lactic acid bacteria and neutralized by NIL, then coned., and mixed with the more or less dried pulp. E.g., 4100 kg. beets was crushed, yielding 2890 kg. juice (11%, sugar) and 1210 kg. pulp. To the juice was added 5%> by wt. of pulp, dried at 30, and the juice fermented by Thermaharterium delbriicki at 50, gradually neutralizing it by a 22% NIL soln. For 48 hrs. pH was kept between 5 and 6 and 90% of the sugar converted into lactic acid. The lactate soln. was coned, to JA of its vol., and the inspissated liquid (about 10001.) mixed with the pulp, weighing about 23% of its former wt. There was obtained 1300 kg. fodder with 3% N content. A. J. C. van de Waal Protein-fat concentrates from chick-hatchery wastes by treatment with lignin. Wm. D. McFarlanc and Nikolai Nikolaiczuk (to The Ogilvie Flour Mills Co., Ltd.). U.S. 2,418,311, Apr. 1. 1947. A protein-fat concentrate suitable for use in mixed feeds may be prepd. from chick- hatchery waste by cooking it with sulfite waste liquor. A mixt. of 200 parts of the waste and 35 parts of sulfite waste liquor was boiled for about 5 min. by direct steam. The coaguluin, pressed and dried, contained on a shell-free basis crude protein 50.35, fat 39.75, ash 2.46, and water 1.2%. The amts, of protein and fat recovered were ap prox. 92% and 94%, resp. E.
