  • Patent number: 6730343
    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.

  • Publication number: 20040018285
    Abstract: A method for producing a coconut water beverage having a pH below 4.5 by adding a food grade acid to coconut water. The method coverts coconut water from a low-acid food to a high-acid food which allows the coconut water to be subjected to less severe commercial sterilization processing and preserves the natural taste and aroma of the coconut water. The present invention is also directed to a blended beverage comprising coconut water and fruit juice and having natural isotonic properties.

  • Patent number: 6544577
    Abstract: Citrus pulp products are provided which incorporate components from pulp material separated from a citrus juice source. Naringin, limonin or other bitterant levels are reduced substantially in the pulp components. In particular applications, the debittered citrus pulp is a grapefruit-originating bland clouding agent, a citrus pulp wash bland clouding agent, or a citrus peel juice bland clouding agent.

  • Publication number: 20030064144
    Abstract: Juices are processed to remove naturally occurring components which detract from the quality of the fruit juice. Such components are removed by contacting the juice with an adsorptive rein in order to provide an enhanced fruit juice supply. Preferred juices are citrus juices.

  • Publication number: 20030064140
    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.

  • Patent number: 6054168
    Abstract: Citrus products are provided which incorporate components from pulp material separated from a citrus juice source. The invention is especially beneficial in connection with grapefruit sources. Naringin or other bitterant levels are reduced substantially in all phases of the citrus source, including pulp components. In a particular application, the citrus product is a grapefruit juice product which is organoleptically identified as grapefruit juice when it stands alone but is not organoleptically identified as grapefruit juice when blended with other fruit juice sources.
