Descripción de la invenciónDescription of the invention

Se ha desarrollado ahora un procedimiento simple y económico en el que, a partir de hortalizas, se obtiene un zumo transparente. Con este procedimiento no hay desnaturalización de proteínas ni descomposición de vitaminas.A simple procedure has now been developed and economic in which, from vegetables, a juice is obtained transparent. With this procedure there is no denaturation of proteins or breakdown of vitamins.

Según un primer aspecto, la presente invención proporciona un procedimiento de obtención de un zumo de hortalizas transparente, con las características de estar aliñado, poseer el sabor y aroma de las hortalizas de partida o mezclas de ellas, como por ejemplo el gazpacho. Opcionalmente puede gasificarse, presentando así la apariencia de una bebida espumosa.According to a first aspect, the present invention provides a procedure for obtaining a vegetable juice transparent, with the characteristics of being seasoned, possessing the flavor and aroma of the starting vegetables or mixtures thereof, such as for example the gazpacho. Optionally it can be gasified, thus presenting the appearance of a foamy drink.

El procedimiento comprende las etapas de:The procedure comprises the steps of:

a) licuar separadamente las hortalizas para obtener zumos;a) liquefy the vegetables separately to get juices;

b) colar cada uno de los zumos obtenidos, a fin de eliminar las partes más gruesas;b) strain each of the juices obtained, in order to remove the thickest parts;

c) filtrar cada zumo colado, mediante un filtro con diámetro de poro adecuado para terminar de eliminar las partes más gruesas.c) filter each strained juice, using a filter with adequate pore diameter to finish removing the parts thicker.

d) mezclar los zumos filtrados, obteniéndose una mezcla de zumos, a la que se añade agua y aliño.d) mix the filtered juices, obtaining a  juice mix, to which water and dressing is added.

e) filtrar, al menos una vez, empleándose un medio filtrante de tamaño de poro menor al de la etapa c).e) filter, at least once, using a filter medium of pore size smaller than that of step c).

Existe la opción de gasificar con CO_{2}.There is the option to gasify with CO2.

Las etapas a) a c) se realizan novedosamente, mediante el tratamiento por separado de las hortalizas y de los zumos obtenidos, con el fin de obtener un producto final compensado.Stages a) to c) are carried out novelly, through the separate treatment of vegetables and juices obtained, in order to obtain a final product compensated

Para separar los sólidos suspendidos en el zumo producido, en las etapas de filtrado, se emplean medios filtrantes que pueden consistir en filtros, membranas de microfiltración, o bien en tierra de diatomeas, medios de ultrafiltración y equipos de flujo tangencial. No obstante, también se pueden emplear equipos de centrifugación para llevar a cabo la separación.To separate suspended solids in the juice produced, in the filtering stages, filter media are used which may consist of filters, microfiltration membranes, or well in diatomaceous earth, ultrafiltration media and equipment tangential flow However, you can also use equipment centrifugation to carry out the separation.

Los medios filtrantes están constituidos de celulosa, sus derivados (nitratos, acetatos) y mezclas de ellos. También, pueden ser de nylon, polipropileno y politetraflúoretileno (PTF).The filter media are constituted of Cellulose, its derivatives (nitrates, acetates) and mixtures thereof. Also, they can be nylon, polypropylene and polytetrafluoroethylene (PTF).

A fin de lograr un mayor brillo y transparencia del producto final, la etapa e) se repite de forma secuencial usando medios filtrantes con tamaño de poro decreciente.In order to achieve greater brightness and transparency of the final product, step e) is repeated sequentially using filter media with decreasing pore size.

De acuerdo con un segundo aspecto, la invención proporciona un zumo de hortalizas transparente que se obtiene mediante el procedimiento detallado anteriormente. Este comprende zumo de hortalizas, agua, aliño y opcionalmente CO_{2}.According to a second aspect, the invention provides a transparent vegetable juice that is obtained by the procedure detailed above. This includes vegetable juice, water, seasoning and optionally CO2.

La invención será descrita ahora, sólo a título ilustrativo, por medio del siguiente ejemplo que de ningún modo deberá ser considerado como limitativo del alcance de la invención.The invention will now be described, only by way of illustrative, by way of the following example that in no way should be considered as limiting the scope of the invention.

Descripción de un modo de realización de la invenciónDescription of an embodiment of the invention

Se parte de la siguiente materia prima, constituida por las hortalizas cuyas cantidades se expresan en kg.: 3 de tomate (variedad zaragozana); 0,4 de pepino corto; 0,2 de pimiento verde (italiano); 0,3 de cebolleta; 0,1 de pimiento morrón; 0,005 de ajo. De forma separada, son introducidas en una licuadora para licuarlas y obtener de cada una de ellas un zumo. A continuación, cada uno de los zumos resultantes se les hace pasar por un colador. Así, se eliminarán los sólidos más gruesos, tales como restos de pieles, fibras, pepitas, etc.Be part of the following raw material, constituted by vegetables whose quantities are expressed in kg .: 3 of tomato (variety zaragozana); 0.4 short cucumber; 0.2 of green pepper (Italian); 0.3 chive; 0.1 pepper sweet pepper 0.005 garlic Separately, they are introduced in a blender to liquefy them and obtain a juice from each of them. TO then each of the resulting juices is passed on For a strainer. Thus, thicker solids, such as as remains of skins, fibers, nuggets, etc.

Posteriormente, cada uno de los zumos colados se filtran, también por separado, mediante el empleo de un filtro de celulosa de tamaño de poro de 60 \mu. Si llegara a colmatarse el filtro, se sustituiría por otro similar.Subsequently, each of the strained juices is  filter, also separately, by using a filter 60 µg pore size cellulose. If it were to fill the filter, would be replaced by a similar one.

Al final de esta etapa, se obtienen los siguientes resultados, expresados como porcentaje, en peso, de zumo líquido colado y filtrado con respecto al peso inicial de zumo obtenido en la primera etapa de licuar: tomate, 40%; pepino, 50%; pimiento verde, 60%; cebolla, 55% y pimiento morrón, 65%; ajo, 40%.At the end of this stage, the following results, expressed as a percentage, by weight, of juice  strained and filtered liquid with respect to the initial weight of juice obtained in the first stage of liquefying: tomato, 40%; cucumber, 50%; green pepper, 60%; onion, 55% and bell pepper, 65%; Garlic, 40%

A continuación, dichos zumos son mezclados, según la siguiente proporción, expresadas las cantidades de zumo en kg de peso: tomate, 1; pepino, 0,18; pimiento verde, 0,09; cebolla, 0,125; pimiento rojo, 0,045; ajo, 0, 0015. A esta mezcla se le añade 750 g de agua, sal y vinagre.Then these juices are mixed, according to the following proportion, expressed the amounts of juice in  kg weight: tomato, 1; cucumber, 0.18; green pepper, 0.09; onion, 0.125; red pepper, 0.045; garlic, 0.0015. To this mixture 750 g of water, salt and vinegar are added.

Dicha mezcla se somete a filtración, utilizando en esta ocasión un filtro de 10 \mu. En esta realización, se repite esta misma operación cuatro veces más, disminuyendo cada vez el tamaño de poro del medio filtrante. La primera repetición emplea un filtro de 1 \mu y las tres restantes: 0,8 \mu; 0,4 \mu y 0,2 \mu, respectivamente.Said mixture is subjected to filtration, using this time a 10 µ filter. In this embodiment, it repeat this same operation four more times, decreasing each time the pore size of the filter medium. The first repetition employs a 1 µ filter and the remaining three: 0.8 µ; 0.4 µ and 0.2 µ, respectively.

Luego, la mezcla filtrada es transportada a un sifón, en donde se le añade una carga de CO_{2} por cada litro de mezcla y posteriormente, se somete a refrigeración a 5ºC, durante 1 hora. En esta realización, se añaden 8 g de CO_{2}.Then, the filtered mixture is transported to a siphon, where a charge of CO2 is added for each liter of  mixture and subsequently, it is subjected to cooling at 5 ° C, during 1 hour. In this embodiment, 8 g of CO 2 are added.
