  • Patent number: 4775477
    Abstract: A process for the extraction of cranberry presscake is disclosed which involves the steps of grinding the presscake, preferably with a filter aid like rice hulls, subjecting this mixture to water extraction, microfiltering the extract to remove colloidal high molecular weight components and passing the microfiltered extract through reverse osmosis to recover a red-colored solution.

  • Patent number: 4508745
    Abstract: A method of hydrolyzing a coffee extraction residue material to produce a mannan oligomer solution having oligomers from DP 1 to DP 10 is disclosed. The coffee material, preferably spent grounds from a commercial percolation system, is hydrolyzed in a reactor in the presence of an acid catalyst. A tubular plug flow reactor is convenient, although any reactor providing for the relatively high temperature, short time reaction will suffice. Particular acid catalysts include sulphuric acid, phosphoric acid, acetic acid and carbon dioxide gas. Depending on the specific time, temperature and catalyst concentration selected, a mannan oligomer solution having any desired distribution of oligomers between DP 1 and DP 10 is produced.

  • Patent number: 4450182
    Abstract: Process for making a frozen foam by reducing the calcium activity of a dairy medium by at least about 70% and adding gum, carbohydrate and water. After adding a lipid sol, the mix is homogenized, cooled, whipped and frozen.

  • Patent number: 4303451
    Abstract: The flavor of waxy maize starch intended for use in thickened food compositions are modified by heat treating the starch to a temperature between about 120.degree. and about 200.degree. C. for a time period of less than 1 hour up to about 24 hours. The heat-treated waxy maize is then pregelatinized and remains flavor-free with a suitable texture for incorporation by mixing in thickened food compositions such as instant puddings.

  • Patent number: 4296132
    Abstract: The object of the invention is to provide a dog food of improved acceptability.Dog foods, no matter how nutritious, must be palatable for the dogs to receive the proper nutrition. This invention provides a dog food of improved palatability by the use of magnesium oleate as a palatant. The preferred embodiment employs magnesium oleate in a surface fat coating to enhance the palatability of a dry dog food. Levels of about 0.2% to about 0.4% based on the total weight of the food are most preferred.

  • Patent number: 4103040
    Abstract: Wet egg yolk is combined with edible oil by high energy, high shear mixing. During mixing cholesterol is extracted from the yolk by the oil. Simultaneously the ratio of polyunsaturated fat to saturated fat in the yolk is increased. The wet yolk is separated from the oil and can be made a constituent of various egg products.

  • Patent number: 3970766
    Abstract: Volatile flavoring compounds such as acetaldehyde are fixed in low amounts by having the compound present in solution during the crystallization of sucrose. It is believed that the volatile flavors are entrapped as impurities within the crystal structure. The resulting compositions have excellent stability over a wide range of humidities, are soluble in both hot and cold water, and have application as flavor and aroma modifiers for foods.

  • Patent number: 3965273
    Abstract: A dry carbonation source for preparing a carbonated beverage and a method for preparing the same, and a dry carbonated beverage concentrate are provided. The dry carbonation source is prepared by reducing the particle size of calcium carbonate in presence of an aqueous solution of a carbohydrate to form a colloidal suspension of calcium carbonate in the aqueous carbohydrate solution, and then drying this suspension to provide a solid suspension of finely-divided calcium carbonate dispersed within a matrix of the carbohydrate. This dry carbonation source is employed with other beverage ingredients to provide a dry carbonated beverage concentrate which readily dissolves to provide a carbonated beverage free from sediment.

  • Patent number: 3958033
    Abstract: A shelf-stable, protein free emulsion having a pH within the range of 6-8 consisting of 0.1-1 part neutral type fat, 1 part water, 2 parts sugar and about 0.25% to about 7% by weight of an emulsufier selected from sodium stearyl fumarate and sodium succinoylated monoglycerides. An adjunct emulsifier, such as propylene glycol monostearate as well as food flavoring and coloring may also be present.

  • Patent number: 3939289
    Abstract: A dry carbonation source for preparing carbonated beverages, the method of preparing the carbonation source and a carbonated beverage concentrate employing the same are provided. The dry carbonation source is prepared by co-grinding calcium carbonate with an anhydrous, non-toxic acid. This dry carbonation source will rapidly dissolve to provide a clear, carbonated beverage with no undesirable sediment or unsightly surface film when mixed with water, a sweetener and a flavorant.
