  • Patent number: 9210948
    Abstract: The present invention concerns compositions and methods relating to the addition and use of par-baked and milled coffee beans in food products, beverages, and dietary supplements. Par-baked and milled coffee beans are a novel alternative to more costly chlorogenic acid extracts, and are edible and palatable as a food ingredient. The ingredient is prepared from the entire Coffea robusta or arabica green coffee bean and provides substantially increased amounts of dietary chlorogenic acid antioxidants compared to roasted beans. When the green coffee bean is appropriately par-baked at a temperature significantly lower than coffee roasting temperatures, the bean retains significant moisture, yet becomes embrittled, enabling milling to produce fine and beneficially hydrophilic particles, without any significant loss of bioactive chlorogenic acid and without significant pyrolysis occurring.

  • Publication number: 20110123700
    Abstract: The patent is a new development of an Instant Liquid Tea Concentrate, according to the norms and standards of food science and related industries. Since the discovery of tea as a healthy drink some 4000 years ago, conventionally, the tea leaves have been dissolved in hot or cold water before consumption. The derivatives of tea would dissolve in hot or cold water with flavor and aromas creating a tasty, healthy drink. A tea bag, for instance, uses the same traditional method, though with reduced preparatory hazard. In addition, tea extracts in powder forms are manufactured with chemical extraction methods. In a number of processes, the tea extract in powder form is followed by the preparation of aqueous tea concentrates as a secondary product. Accordingly, the powdered tea extracts is dispersed in water while adding preservatives in order to manufacture aqueous tea concentrates. This aqueous tea concentrates differ from the “INSTANT LIQUID TEA CONCENTRATE”.

  • Patent number: 4486453
    Abstract: This invention relates to a method for removal of residual solvent from decaffeinated coffee beans. In particular, differential pressure stripping comprises a method of flash evaporation of solvent from the beans by means of an alternating cycle of pressure variations. The time and steam requirements for desolventizing are reduced when compared to traditional methods for removal of the same solvent. This reduces the residence time of the coffee beans in conditions of high temperature and high moisture, thereby preventing negative flavor changes in the resultant coffee products.

  • Patent number: 4474821
    Abstract: This invention relates to an improved countercurrent extraction process for accelerated decaffeination of coffee beans, and to the novel decaffeinated coffee product generated thereby. In particular, turbulent flow of the extracting solvent is used to obtain a substantially accelerated decaffeination rate involving a caffeine extraction time of only from about 3 to about 5 hours. Since the rate of extraction of non-caffeine coffee solubles is not correspondingly accelerated, the decrease in extraction time minimizes the loss of these valuable materials. Use of multiple vessels in countercurrent operation also decreases the loss of non-caffeine coffee solubles, resulting in an improved decaffeinated coffee.

  • Patent number: 4315036
    Abstract: An aqueous extract of tea, containing native tea tannins and caffeine, is cooled to provide an aqueous solubles phase containing cold-water soluble components of the extract, including a minor portion of the caffeine, and an insolubles phase containing tea tannins complexed with a major portion of the caffeine. The aqueous solubles phase is separated from the insolubles phase, and the latter is subjected to decaffeination to provide decaffeinated tannins which may then be recombined with the aqueous solubles phase. The resulting treated extract from which the major portion of the caffeine has been removed can be dried or, if desired, subjected to further decaffeination and thereafter dried to provide a cold-water-soluble decaffeinated tea. Further features of the invention are set forth in the following description.
