  • Patent number: 9345250
    Abstract: The present invention provides a method for preparing a solubilized composition containing an oil-soluble substance having both acid and heat resistance, including: the step of dissolving an oil-soluble substance and two or three emulsifiers selected from (1) an emulsifier E1 comprising an ester of a fatty acid having an HLB of not less than 10 and not more than 14 carbon atoms with a polyglycerol having a polymerization degree of not less than 3, (2) an emulsifier E2 comprising an ester of a fatty acid having an HLB of not less than 10 and not more than 14 carbon atoms with sucrose, or (3) an emulsifier E3 comprising lecithin in which phosphatidylcholine accounts for not less than 50% and/or lysolecithin in which lysophosphatidylcholine accounts for not less than 50% of a phospholipid content in (a) ethanol or (b) a mixed solvent of ethanol with at least one selected from the group consisting of acetone, hexane, and ethyl acetate to prepare a transparent solution; and the step of distilling the solvent of

  • Patent number: 5955327
    Abstract: In accordance with the present invention, there is provided a process for manufacturing vegetable lysolecithins which comprises allowing a hydrolysis enzyme consisting of phospholipase A.sub.1 or A.sub.2 to act on a hydrated lecithin used as a starting material, then adding for stirring to the resultant lysolecithin solution acetone in a proportion on a volume basis of either 1 to 4, or 5 or more, against the water contained in said resultant lysolecithin solution to thereby either float or precipitate the lysolecithin phase, then separating out said lysolecithin phase, followed by repetition of the acetone extraction procedure to separate for removal free fatty acids by-produced in the said lysolecithin production reaction as well as oil-soluble impurities originated from the starting material.The process of the present invention can produce high-quality vegetable lysolecithins with reduced discoloration and improved flavor in increased yields.

  • Patent number: 5609904
    Abstract: A whipping cream composition includes (a) 35-70 weight % total solids including (i) 16-40 weight % oil and fat, and (ii) 0.3 to 6 weight % combined casein protein and whey protein, having a weight ratio of casein protein/whey protein of 0.24 to 3.8; (b) an emulsifier including based on the composition, 0.01 to 0.5 weight % lecithin, 0.05 to 1.2 weight % saturated fatty-acid ester of a polyglycerol having a mean glycerol polymerization degree of not less than 5 in an HLB value of not less than 9, and 0.02 to 0.6 weight % saturated fatty acid ester of a polyglycerol having a mean glycerol polymerization degree of not less than 2 in an HLB value of less than 7, and (c) 0.05 to 5 weight %, based on the composition, of at least one edible fiber selected from the group consisting of cellulose, hemicellulose, sparingly digestive dextrin, modified starch, and a combination thereof.

  • Patent number: 5562943
    Abstract: A salt composition is provided for preventing excess intake of salt (sodium chloride) and achieving a well balanced intake of minerals. The composition which is used in the place of conventional table salt consists essentially of 100 parts by weight of a mixture containing 30 to 75% by weight of sodium chloride and 25 to 70% by weight of sylvinite admixed with 5 to 60 parts by weight of a citrate. Seasonings, such as soybean paste and soy sauce, and foods, such as pickles and kimchi, can be prepared with such a salt composition.

The composition which is used in place of conventional table salt consists essentially of 100 parts by weight of a mixture containing 30 to 75% by weight of table salt and 25 to 70% by weight of potassium chloride being admixed with 5 to 60 parts by weight of a citric acid salt, e.g. tripotassium citrate. Seasonings, such as soybean paste and soy sauce, and foods, such as pickles and kimchi, can be prepared with such salt composition.
