  • Patent number: 7264837
    Abstract: The deacidification of citrus juice with ion exchange resin is described. Maintaining a high acid condition of the juice is achieved by passing the juice through regenerated resin that is preconditioned with an aqueous food-grade acid, preferably citric acid. Additionally or optionally, an early bed volume or multiple early bed volumes of juice flow are at a rapid flow rate. The products obtained also are described, and they may be any deacidified citrus juice or juice blend where the pH of the juice does not rise above that of an acid food pH for the juice during deacidification. In preferred embodiments, the juice product is orange juice. In another preferred embodiment, the conditioning process is used to provide a deacidified citrus juice product while avoiding raising the pH of any portion of the juice to 4.6 or above so as to control microbial growth of the juice.

  • Patent number: 7074448
    Abstract: A system and process for making a low-acid, single strength juice such as a not from concentrate (NFC) citrus juice are provided in which an initial single strength juice flow can be cooled to a temperature of not greater than about 45° F. and maintained at that temperature or below throughout the process (except during pasteurization). From the initial juice flow, a first portion of the juice is diverted from a second portion of the juice. Suspended solids are separated out from the first portion to provide a solids-reduced juice. The solids-reduced juice is subjected to ion-exchange deacidification. Preferably, a portion of the initial single strength juice flow is added to the deacidified juice immediately after deacidification in order to immediately lower the pH of the deacidified juice to a value that discourages microbial activity.

  • Publication number: 20040161505
    Abstract: A process for deacidifying single strength juice, including not from concentrate (NFC) juice, uses an ion-exchange column. The process includes flowing water into the resin column and draining a fraction of the water from the column to create a head space in the column above the resin beads. Single strength juice is then introduced into the head space and into the resin column. Water is drained from the column until an SOI criterium is met. Single strength juice continues to be introduced into the resin column and treated liquid is directed to the production of deacidified single strength juice, typically until such time as the acidity of the treated liquid exceeds a pre-determined value. Treated single strength juice is removed from the resin column to create a head space in the column. Water then is introduced into the head space and liquid passes through the exit port.
