摘要:
A juice processing system includes at least one fluid line for a concentrated pulp stream, and a flow restrictor coupled in fluid communication with the at least one fluid line for generating a pressure drop in the concentrated pulp stream indicative of a concentration of pulp therein. The system may further include at least one pressure sensor associated with the flow restrictor for sensing the pressure drop, and a controller coupled to the at least one pressure sensor for generating at least one control signal based upon the sensed pressure drop. The control signal may be for an upstream and/or a downstream control device.

The process according to the invention, for producing sugar products from fruits, comprising the steps of: i) demineralizing and decolorizing a fruit juice so as to bring its solid content to comprise from 99% wt to 99,99 % wt of a mixture of saccharides, alcohols and flavonoids; iii) separating by chromatography the demineralized and decolorized fruit juice so as to obtain a glucose-enriched fraction or a fructose-enriched fraction from the fruit juice. The solid content of the glucose-enriched fraction comprises at least from 70% wt to 99.99% wt of glucose; the solid content of the fructose-enriched fraction comprises from 70% wt to 99.99% wt of fructose. The low content of anions and cations of the fruit juice to be treated by chromatography greatly increase the yield of the chromatographic treatment and the purity of the glucose- and fructose-enriched fractions obtained through it.

A method of solidifying particularly sugar solutions from grape processing that can also be used for the production of concentrated, rectified must (CRM) is characterized in that the step of solidification is carried out by leading the sugar solution to a sugar concentration which is suitable for the solidification of their components able to be solidified from 50% by weight of sugars to the maximum value of the obtainable concentration. A solidified sugar product is obtained that can also be separated from the not solidified components and offers a number of advantages regarding both package and use as well as storage and transportation.

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.

Provided is a new method as well as a related installation to realize the extraction of vegetable juice from a vegetable residue and/or a vegetable peelings residue, of which the latter was lost for human consumption up to now as it was assumed that no more vegetable juice could be extracted from it. Surprisingly, tests demonstrated that it was nevertheless possible to technically extract the useful quantity of vegetable juice almost entirely from the residue. In particular, this purpose is achieved by using e.g. a fruit squeezing unit, known per se, with which under normal conditions only very juicy fruits are squeezed.

This invention relates to the production of flavour concentrates based on apple or pear juice or other fruit or vegetable juices and to novel concentrates. The process comprises subjecting a fruit or vegetable distillate to reverse osmosis to form an aqueous permeate and a retentate containing a flavour chemical. The reverse osmosis is continued until the retentate can phase separate into an aqeous phase and a substantially anhydrous organic phase. The organic phase, which contains a high proportion of the flavour chemicals, is recovered. The organic phase concentrate produced has a high concentration of flavour chemicals and is substantially free of saccharide.

Procédé efficace de séparation et de récupération des volatils de l'arôme et du goût des jus de fruits ou de légumes, et de diminution du taux de sucre dans les jus. Le procédé consiste à enlever les volatils de l'arôme et du goût du jus par la formation d'un micro-aérosol au moyen de l'atomisation du jus à une température comprise entre 45 °C et 110 °C, à travers un ajutage dont le diamètre est compris entre environ 100 et 1200 microns, à une vitesse comprise entre 100 m/sec et 250 m/sec, jusque dans une chambre à vide à entre 5 mm et 200 mm Hg, et à des températures comprises entre 10 °C et environ 55 °C, puis à traiter la fraction de jus récupérée avec une levure. On enlève par distillation l'alcool formé pendant cette réaction de fermentation, de préférence au moyen du même processus de dispersion en aérosol que celui utilisé pour enlever les volatils. On peut ensuite rendre au jus les volatils de l'arôme et du goût afin d'obtenir un délicieux jus de fruits à basses calories.

Cette invention concerne la production d'arômes concentrés à base de jus de pomme ou de poire ou d'un autre fruit ou des jus de légumes, ainsi que de nouveaux concentrés. Selon le procédé, on soumet un distillat de fruit ou de légume à une osmose inverse pour former un perméat aqueux et un rétentat contenant une substance chimique aromatique. L'osmose inverse se poursuit jusq'à ce que le rétentat puisse se séparer en une phase aqueuse et une phase organique anhydre. On récupère la phase organique contenant une proportion élevée des substances chimiques aromatiques. Le concentré produit par la phase organique possède une concentration élevée en substances chimiques aromatiques et est exempt de saccharide.
