きるトマトジュースの高濃縮方法に関するものである。FIELD OF THE INVENTION The present invention relates to a method for highly concentrating tomato juice. Highly concentrated tomato juice is widely used as an intermediate and final product. The highly concentrated product is required to possess the original quality of tomato (color, taste, aroma, etc.). TECHNICAL FIELD The present invention relates to a method for highly enriching tomato juice, which enables continuous and stable production of highly concentrated products having the original quality of tomatoes.

However, this conventional method has a drawback in that the quality deterioration inherent in tomatoes is unavoidable because the conventional method involves phase conversion to evaporate water, although the degree varies depending on the conditions.

ないのである。Therefore, conventionally, reverse osmosis concentration has been carried out and proposed as a method for concentrating tomato juice which does not involve phase conversion and therefore retains the original quality of tomato (Japanese Patent Publication No. 59-53824 and Japanese Patent Laid-Open No. 21326/1993). ). However, these conventional methods have a drawback that it is difficult to continuously and stably produce highly concentrated tomato juice. In these conventional methods, since the tomato juice is a highly viscous one containing a relatively large amount of pulp, it was originally impossible to produce a highly concentrated product of Brix 20% or more from the tomato juice, or it was temporarily Although it is possible to manufacture such a highly concentrated product, since the pressure loss is too large, there are restrictions on the structure of the device or its operation,
Such highly concentrated products cannot be continuously and stably manufactured.

It is set to 10 to 40% of the membrane area of the stage unit.
Salt rejection rate of 90% as a membrane module of the 1st stage unit
If less than the tomato is used, the tomato's original active ingredient will be lost. Further, if a salt module having a salt rejection rate of more than 30% is used as the membrane unit of the second stage unit, the required amount of permeate cannot be obtained and it is necessary to increase the membrane area, resulting in a large pressure loss as a whole. If it becomes too high, it will not be possible to continuously and stably manufacture highly concentrated products with Brix of 20% or more. If the membrane area of the second-stage unit is less than 10% of the membrane area of the first-stage unit, a highly concentrated product with Brix of 20% or more cannot be manufactured. The pressure loss becomes too large, and it becomes impossible to continuously and stably manufacture highly concentrated products with Brix of 20% or more.

ができないのである。FIG. 2 illustrates the relationship between the area ratio and the Brix (%) of the concentrate obtained when the film area ratio (%) of the second-stage unit to the first-stage unit is changed in FIG. It is a graph. Here, tomato juice with 5.0% Brix, a first stage unit equipped with a tubular membrane module with a total membrane area of 15 m 2 with a salt rejection rate of 95%, and a tubular membrane module with a salt inhibition rate of 20% were installed. It is continuously flowed down to the second-stage unit at 300 liters / hour for 10 hours in a transient manner. As is clear from FIG. 2, when the membrane area ratio of the second-stage unit is less than 10%, the membrane area of the second-stage unit is insufficient and the required amount of permeate cannot be obtained. The above highly concentrated product could not be manufactured, and conversely the membrane area ratio of the second stage unit was 4
If it exceeds 0%, the pressure loss due to the second-stage unit becomes too large, and continuous stable operation of the device becomes difficult.
Brix 20% or more highly concentrated products cannot be continuously and stably manufactured.

% Tomato juice, a salt rejection rate of 99%, a first stage unit equipped with a tubular membrane module having a total membrane area of 15 m 2 and a membrane area ratio of 20% for the first stage unit.
The second-stage unit equipped with the tubular membrane module of No. 1 is continuously flowed down at a rate of 300 liters / hour for 10 hours. As is clear from FIG. 3, if the salt inhibition rate of the second-stage unit exceeds 30%, the required amount of permeate cannot be obtained from the second-stage unit, so a highly concentrated product with Brix of 20% or more is produced. You cannot do it.
