Abstract

PURPOSE:To obtain a juice at a low cost, keeping the nutrient of the raw material, by immersing fruit, etc., in hot oil, dehydrating the fruit by reducing the pressure in two steps, separating the oil with a press under reduced pressure, boiling the deoiled solid and separating the objective juice from the boiled solution. CONSTITUTION:Fruits, vegetables, etc., containing various vitamins are immersed in hot oil and dehydrated (preferably to a water-content of about 10%) by evacuating the system in two steps, i.e. slight evacuation followed by the intensive evacuation. Most part of the oil is separated with a press under reduced pressure (preferably to a residual oil content of 7-8%) and preferably the oil is removed e.g. with a solvent to a residual oil content of about 1%. The remaining solid is boiled and the objective juice is obtained from the resultant solution.

Description

[Detailed description of the invention] (b) Industrial application field The present invention relates to a method for producing beverage fruit juice.

(b) Conventional technology and its problems Although there have been many fruit juice drinks in the past, many of the various vitamins contained in the fruit itself are lost during the manufacturing process and have a low residual rate, making them harmful to health. It couldn't be called a drink.

This is because various vitamins are sensitive to heat and easily leak and decompose, so if you try to retain the same vitamins even after processing them into fruit juice, the manufacturing process will be complicated and the cost will be high, making it unprofitable. There was a situation where I couldn't get it.

Therefore, various considerations have been made as to whether there is a way to completely preserve the various nutritional components that fruits originally have and to make juice at a low cost.

(C) Means for Solving the Problems In the present invention, fruits, vegetables, etc. containing various vitamins are immersed in heated oil in a cupper, and the initial pressure is small and the second pressure is reduced. The oil is depressurized in two stages and dehydrated depending on the oil temperature, then most of the oil is separated from the solids in a press under reduced pressure conditions, and the deoiled solids are boiled and rejuice is made from boiled liquid. It is an object of the present invention to provide a method for producing a beverage fruit juice characterized by producing the following.

(d) Function When producing fruit juice for beverages, raw materials such as fruits and vegetables containing various vitamins are poured into heated oil in a kettle.
The raw material is immersed in the same vacuum, the pressure in the same container is reduced in two stages, and the above raw material is dehydrated depending on the oil temperature. Furthermore, most of the oil is separated from the solid matter by a compressor under the same reduced pressure conditions, and the deoiled solid material is obtained. In this case, the two-stage depressurization is performed by reducing the initial pressure reduction to stabilize the coagulation of the various vitamins contained in the raw materials and prevent these components from flowing out and decomposing. By increasing the vacuum, water in the raw material is evaporated and replaced with heated oil in the tissue, allowing the heated oil to deeply penetrate into the raw material tissue and heat the heated oil from inside and outside the tissue. It is heated as a medium and enables dehydration treatment in a short time.Moreover, by squeezing under reduced pressure conditions, it is possible to improve the oil removal efficiency, and furthermore, the deoiled solids can be By boiling, it is possible to produce a fruit juice beverage that completely retains the nutritional components such as various vitamins originally contained in the raw material.

(e) Effects According to the present invention, the various vitamins contained in fruits, vegetables, etc. can be completely secured and fruit juice can be made.
It can be used as a health drink for sick people who have to rely on liquid food, and since it can be produced in large quantities in a short period of time, it has the effect of significantly reducing costs.

(F) Example To explain in detail the example of the present invention, fruits and vegetables containing large amounts of various vitamins are used as raw materials, such as apples, mandarin oranges, lemons, cabbage, Chinese cabbage, lettuce, etc. Raw materials such as carrots and spinach are crushed and first put into heated oil stored in a kutuka.

A certain amount of oil is stored in the cooker, and steam is forced into the cooker's V-ket to heat the oil in the cooker to a certain degree.

The raw materials that have been put into the oil and immersed in the oil are dehydrated by reducing the pressure to 10 to 20 mmHg for 30 minutes after being put into the oil, and reducing the moisture content of the raw materials to around 10% in about 1 hour. conduct.

After dehydration, the raw material is separated from the heated oil under the reduced pressure conditions described above to obtain a flat solid. Note that deoiling under reduced pressure conditions is also performed in the process of compressing raw materials.

Next, the solid matter with a residual oil percentage of 7 to 8% is taken out under reduced pressure conditions or normal pressure conditions, and normal hexane or the like as a solvent for further oil decomposition is sprayed. The residual oil in the solid is eluted into a solvent to miscellate it, and the miscella is evaporated by heating at about 67 to 69° C. to remove the oil to a solid residual oil percentage of about 1%.

Then, the solid matter having a residual oil percentage of about 1% is boiled, and the broth is taken out as it is or concentrated and recovered.

In addition, before putting the raw materials into the kettle, it is possible to mix them with seasoning ingredients to improve the taste, such as spices (salt, chili pepper, pepper, sugar). A small pressure reduction operation is followed by a sudden large pressure reduction operation.

Claims (1)

[Claims] 1) Fruits, vegetables, etc. containing various vitamins are immersed in heated oil in a cooker, and the pressure inside the cooker is reduced in two stages, with a small initial pressure reduction and a large second pressure reduction, and dehydration treatment is performed depending on the oil temperature. A method for producing a beverage fruit juice, which comprises: separating most of the oil from the solid matter using a press under reduced pressure conditions, and boiling the deoiled solid matter to produce juice from the broth.
