Abstract:
Cette invention concerne un procédé de traitement de fruits ou de légumes après récolte, caractérisé en ce qu'il comprend les étapes consistant à:
porter à une température de 40 à 60°C une composition traitante comprenant dans un véhicule aqueux, au moins un agent traitant choisi parmi un agent antioxydant de type polyphénol et un composé terpénique, et mettre les fruits ou légumes au contact de la composition à ladite température pendant une durée inférieure ou égale à 10 minutes.
Abstract:
A process for preparing fruits or vegetables and the fruits or vegetables prepared by the process. In particular, the vegetables may be diced tomatoes. The process comprises continuously exposing the diced fruits or vegetables to a calcium salt solution especially calcium chloride solution comprising fruit or vegetable juice. The fruits or vegetables are exposed to the solution for a predetermined period of time. Calcium salt solution is continuously recovered, measured (122, 123) and compared to a predetermined value or programmable controller microprocessor (124) set-point. Any necessary adjustments are made to maintain the concentration within the accepted range of a predetermined value. The adjusted solution continuously feeds a nozzle (20) bathing the diced fruits or vegetables.
Abstract:
A method for slowing down the basal metabolism and controlling the ripening process of fruits and similar. It consists of dissolving acetic acid in a determined volumen of water, adding a determined amount of potassium permanganate and of sodium periodate, by stirring until dissolving, and adding then powdered sepiolite and after a later stirring, a - paste will be obtained which will be extruded inside an oven. Next, the moisture rate is assessed and the paste is distributed in filter-like sections or unwoven textile material bags.
Abstract:
La présente invention concerne un procédé pour réduire les pertes en éléments constitutifs des légumes et notamment des champignons lors de leur mise en conserve comprenant l'imprégnation sous vide par un liquide, dans un tube (1) lié par l'intermédiaire d'un réservoir à vide (10) à une pompe à vide (7). Cette imprégnation sous vide est suivie d'un traitement thermique, caractérisé en ce que l'imprégnation représente 60 à 80 % en poids du légume paré à sec et en ce que le traitement thermique consiste à durcir superficiellement les légumes par passage dans un four à rayonnement infra-rouge entre 300°C et 600°C pendant une durée comprise entre 2 et 6 mn, puis à réaliser une cuisson à coeur du légume à une température d'environ 80°C, de façon à coaguler l'albumine naturelle et à transformer les acides aminés.
Abstract:
Freshly picked washed mushrooms are subjected to a modified atmosphere and infused by application of positive or negative pressure with a solution containing a particulate heat stable gel forming material. Upon blanching in boiling water the weight loss experienced is reduced from a normal 25% to 33% loss to between a 2% loss and a 5% or more - weight gain.
Abstract:
A food processing apparatus (20) including a tank (24) having an inlet end (32) for receiving food product and an outlet end (40) for discharging food product, the tank having an inner wall (44) defining a compartment (52) and including a solid, imperforate wall portion (46), fluid being contained in the compartment, and a rotatable auger (88) mounted in the compartment (52), the auger (88) for advancing food product within the compartment (52) from the inlet end (32) toward the outlet end (40), the auger (88) including flights (104) having a flight wall with a radial edge, a clearance space being defined between the radial edge of the flights and the solid, imperforate wall portion (46) of the inner wall (44). Flow of fluid through the clearance space may be inhibited. One of the inner wall and the flight wall may include a perforated wall portion (48). Flow of fluid between the first auger section and the second auger section may be provided through the perforated wall portion (48).
Abstract:
A method of treatment of foodstuffs (A) containing liquids (L 1 ) and air, such as vegetables and mushrooms, comprising a step of a) washing the foodstuffs (A) with a washing liquid (L 2 ), a step of b) draining the foodstuffs (A) and a step of c) removing air from the foodstuffs (A) by applying vacuum. Steps are further provided of d) impregnating the foodstuffs (A) in a closed chamber (5) by applying thereto an atmosphere saturated with an impregnation liquid (L 3 ) and of e) packaging the foodstuffs (A) with a preserving liquid (L 4 ) in a packaging workstation (22). The method further comprises a step of f) steam cooking the foodstuffs (A) in a vessel (11) for at least partially extracting the liquids (L 1 ) contained therein and obtaining a broth (B), a step of g) collecting and storing the broth (B) in a first reservoir (12) connected to the vessel (11) and a step of h) recirculating the broth (B) stored in the first reservoir (12) to the closed chamber (5) of the impregnation step. The impregnation step d) and the packaging step e) are carried out using the broth (B) obtained during the step of cooking f) of batches (Pi) of previous foodstuffs (A) as an impregnation liquid (L 3 ) and as a preserving liquid (L 4 ) respectively.
Abstract:
Provided herein are methods, apparatuses, and systems for treating food articles, including meat, poultry, fish and other seafood, vegetables, fruits and other foods and food processing articles by spraying an antimicrobial or other agent onto the food or food processing articles. One embodiment of the invention may include a method for treating a food article comprising disposing a food article in a cavity within an enclosure having an outer shell and at least one inner plate disposed in the cavity, applying a first charge to a antimicrobial agent, applying a second charge to the at least one inner plate of the same polarity as the first charge, and spraying the antimicrobial agent into the cavity in a manner whereby at least a portion of the antimicrobial agent is caused to be repelled by the at least one inner plate and to at least partially coat the food article.
Abstract:
A device for serving and preserving food items, the device including an open container for holding the food items having one or more side walls and a floor, wherein when the food items are immersed in fluid, typically a preserving fluid, the device is in a preserving state; a liquid-holding compartment, having a tubular form, for holding the fluid when the device is in a serving state; and a liquid-transfer mechanism for transferring the preserving fluid from the open container into the liquid-holding compartment and back. One or more passageways, interconnecting the open container and the liquid-holding compartment, facilitate the transfer of fluid between the open container and the liquid-holding compartment.
