2. Description of the Related Art Generally, a fruit juice product is provided to a consumer by appropriately blending an original fruit juice obtained by squeezing a fruit or removing turbidity by clarification filtration and then filling a container. . In the process of producing this fruit juice product, the original fruit juice may come into contact with the atmosphere, and the quality of the fruit juice components may often change. For example, in the case of fruit juice of apples, especially apples, browning progresses when the fruit juice comes into contact with oxygen in the atmosphere. Usually, commercially available apple juice products have a considerable amount of browning, as can be seen from the color thereof, or are opaque and opaque, and thus have a drawback that they lack refreshing feeling.

Further, the fruit juice product is usually subjected to heat sterilization in the manufacturing process thereof in order to prevent spoilage and deterioration due to the propagation of bacteria during the storage or distribution process.
This heat sterilization is 65 ° C or higher, usually 90 ° C to 120 ° C.
This is often done by heating to the atmosphere, which often produces off-flavor substances. For example, the fruit juice of citrus fruits such as oranges and oranges contains a substance called methylmethionine sulfonium (MMS), which is transformed into dimethyl sulfonium (DMS) which is a causative substance of potato odor by heating. It is considered that the amount of the off-flavor substances produced is generally higher as the heating temperature is higher and the heating time is longer, but it is preferable to heat at a high temperature for a long time to a sufficient sterilizing effect. The above heating conditions are adopted as a compromise. In addition, there is a substance called hydroxymethylfurfural (HMF) synthesized from fructose, which is said to be one of the substances that give a bad flavor, but it is considered that this also promotes the production by heating.

As described above, the production of fruit juice products has hitherto been carried out as an operation in which the respective steps such as squeezing, adjusting, sterilizing, and filling are individually set. As a result, irrationalities such as alteration of fruit juice components and generation of off-flavor substances were generated. Therefore, in order to eliminate such irrationalities and to produce a fruit juice product having a fresh flavor, the opportunity of contacting the fruit juice with the atmosphere is reduced as much as possible, and the time during which the juice is exposed to high temperature,
It was necessary to develop a method optimized as a total process that reduces the frequency, temperature, etc., and also considers other conditions.

This avoids contact of the original juice or the permeated juice with the atmosphere during this period. Moreover, since all of these steps are performed in a nitrogen gas atmosphere, dissolved oxygen can be sufficiently replaced and expelled, and it is not necessary to replace oxygen in the head space of the container with nitrogen during filling. .

According to the present invention, the raw fruit juice obtained by squeezing is first clarified and filtered, and then other steps are carried out. In particular, the heat sterilization treatment is performed after removing the turbid matter by filtration. This has the significance of preventing the production of off-flavor substances derived from turbidity in the heat sterilization treatment, but it is not limited to that.
That is, in the present invention, the sterilizing action by filtration is also utilized by suitably selecting the membrane used for filtration. Of course, since permeated juice after filtration is subjected to high-temperature instantaneous heat sterilization or heat sterilization after filling, filtration does not necessarily require complete sterilization effect, but it is incomplete. Also, by preliminarily removing the bacteria, the conditions for the subsequent heat sterilization can be relaxed. Therefore, for example, if heat sterilization after filling is carried out at 65 to 85 ° C, it will be carried out at a considerably lower temperature than conventionally carried out at 90 to 120 ° C. Alteration of fruit juice components and generation of off-flavor substances due to Especially if you dislike the production of off-flavor substances,
The heat sterilization treatment may be performed at 65 to 75 ° C.

The filtration of the raw juice in the present invention is performed using a ceramic membrane. Since the ceramic membrane has high heat resistance, it is possible to perform heat sterilization of the membrane itself, and thereby the above-mentioned bactericidal action can be fully utilized. Preferably,
It is used in the form of a module that incorporates a monolithic or tubular ceramic membrane filtration element to perform circulating filtration. As the ceramic film, an alumina-based film is preferable because it can be washed with alkali. To expect the sterilization effect by filtration, the pore size of the ceramic membrane should be 0.05
.About.0.5 micron, preferably 0.1 to 0.
More preferably 2 microns. If so-called precoat filtration is performed in combination with a precoat material, even a membrane with a coarser pore size can be expected to have a sterilizing effect, but precoat filtration makes it difficult to effectively use the concentrated liquid as a raw material for blending. Therefore, in the present invention, it is preferable to directly filter the raw juice with a ceramic membrane without using a precoat material.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows an example of a process flow of a suitable apparatus for carrying out the method of the present invention. The raw fruit juice obtained from the fruit squeezing step (not shown) is put into the stock solution tank 1. Stock solution tank 1, ceramic membrane filter 3
And the heat exchanger 5 constitutes a circulation system via the circulation pump 2, and a part of the fruit juice permeates the ceramic membrane to become the permeated fruit juice. The pressure required for the membrane filtration is supplied by the nitrogen gas for sealing introduced into the circulation pump 2 or the stock solution tank 1, but pressurization with nitrogen gas is preferable because heat generation in the circulation pump 2 is reduced. The multi-tubular heat exchanger 5 is provided as necessary in order to suppress the temperature rise in the circulation system. The transparent juice is filled into a container by the filling machine 4,
Finally, the heat sterilization device 6 sterilizes the juice product. According to the process flow of FIG. 1, apple (tsugaru) fruit juice was filtered under the following conditions, and the permeated fruit juice was heat-sterilized. Stock solution tank: 50 liters Sealing nitrogen gas introduction pressure 0.5 kPa Membrane filter: Made by Nippon Insulator Material Alumina monolith type, length 1000 mm, outer diameter 30 mmφ inner diameter 4 mmφ × 19 operating pressure: 200 kPa Membrane surface velocity: 3 m / s membrane Pore size: 0.05, 0.1, 0.2 micron Heat sterilization: 75 ° C., 10 minutes The obtained apple juice product had a light color and high transparency, and had a fresh flavor with almost no off-flavor. Since this apple juice has almost no off-flavor, the quality of the flavor can be evaluated on a higher level. This was confirmed as follows. That is, with respect to the permeated fruit juice after the heat sterilization treatment, a test was conducted by 11 panelists to compare and evaluate the influence of the pore size of the membrane used on flavor.
As a result, all 11 panelists judged that the sample treated with the 0.1 micron film was “good”. As described above, it was also found that when a ceramic membrane having high separation accuracy is adopted, fruit juice having an excellent flavor can be produced by appropriately selecting the membrane pore size.

EFFECTS OF THE INVENTION According to the present invention, since the contact between the fruit juice and the atmosphere in the process of producing the fruit juice product is significantly reduced, the deterioration of the fruit juice components, especially the browning of the fruit fruits, is suppressed. Further, since the heat generation factor in the manufacturing process and the heating temperature during heat sterilization are reduced, generation of off-flavor substances due to heat is suppressed. These make it possible to provide a fruit juice product having a fresh flavor.
