Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method for producing a pineapple drink containing pineapple kernels.

[Conventional technology]

In recent years, as eating habits have improved, conventional simple and homogeneous fruit juice drinks do not necessarily satisfy the texture of consumers. Fruit drinks are becoming more popular.

Regarding pinenut pull, conventionally 1 part pineapple juice (juice concentration 20-25%) and canned pineapple crush (
There is a canned beverage that is made by combining about 5% of pineapple pulp (canned fruit pulp cut into thin pieces with a spit).

[Solving the invention J-begi problem]

This conventional pineapple fruit-containing beverage is made by heating and sterilizing pineapple crush in a canned form, mixing it with pineapple juice, filling it into an empty can, sealing it, and then sterilizing and heating it again. It lacks flavor, the pulp is soft and has a poor texture, and as a fruit drink R1 containing fruit grains, which aims to satisfy both the taste of eating fruit and the taste of drinking fruit juice, it satisfies the texture of consumers. There were some drawbacks that could not be avoided.

Therefore, the object of the present invention is to eliminate the drawbacks of the conventional pineapple fruit-containing beverage, and to provide a pineapple containing pineapple fruit blended with pineapple fruit having a fresh flavor and good texture that are almost the same as pineapple raw chestnuts. Our goal is to provide a method for producing drinks.

[Means of invention to solve problems]

In order to achieve this object, the present invention involves removing the cylindrical pulp for slice canning from fresh pineapple chestnuts, first collecting pulp pieces that do not contain buds from the pulped skin that remains, and then cutting the pulp pieces into small pieces. While producing a large number of pineapple fruit grains, the pulp including buds is collected from the pulped skin remaining after that, and if necessary, mixed with pulp pieces obtained in other processes and squeezed, or The pineapple fruit juice is individually squeezed, the pineapple fruit juice is adjusted, and a predetermined amount of the pineapple fruit obtained in the above step is filled into a container.The pineapple fruit juice obtained in the above step is instantaneously heated and sterilized, then filled, and then the container is filled. It is characterized by being sealed and heat sterilized.

[Effect]

This makes it possible to blend the pulp directly collected from pineapple raw chestnuts as fruit while preventing the contamination of foreign matter such as pineapple buds and seeds, and further maintains the freshness of pineapple raw chestnuts with minimal thermal history. It can be achieved to maintain.

〔Example〕

The present invention will be described in detail below with reference to embodiments shown in the accompanying drawings.

FIG. 1(a) shows a cross section of a pineapple raw chestnut 1 with the top and bottom cut off. As raw materials for the fruit grains and fruit juice of the pineapple drink containing fruit grains used in the method of the present invention, the cylindrical fruit pulp 2 for sliced canning (Fig. 1 (b)) is removed from raw pineapple chestnuts. The remaining pericarp with pulp 3 is used. Pineapple raw chestnut is 1
Grade chestnuts (fruit diameter 2 In/m or more) are suitable.

There are many so-called buds 7 at the interface between the inside of the outer skin 4 of the pericarp 3 with remaining pulp and the remaining pulp 5 (indicated by line 6'?l), and these buds contain minute black seeds. It is.

If these seeds are mixed into a drink, they turn into black, fine suspended particles that disturb the appearance and texture of the drink, significantly reducing its commercial value as a drink. Moreover, these buds are very small, so if they get mixed into the pulp, it is impossible to completely remove them manually, and it is also impossible to separate and remove them by mechanical or chemical methods without destroying the pulp. It's impossible. Therefore, when cutting the pulp to produce fruit from the remaining pulp of the pulped pericarp 3, it is necessary to prevent these buds from being mixed into the pulp.

Conventionally, an eradicator has been used to collect pulp for juice production from the pulp-attached rind, but when this is used, due to its mechanism, the pulp is completely scraped down to the interface 6 between the pericarp and the pulp, so the bud 7 is removed from the pulp. It is undesirable that it is collected by adhering to it.

Therefore, in the present invention, a resizing machine schematically shown in FIG. 2 is used to collect pieces of pulp from the pulped skin, thereby preventing the buds from adhering to the pulp. That is, after removing the cylindrical pulp 2, the outer skin 3 with pulp is removed as shown in Fig. 1 (C).
The fruit is divided into four parts as shown in FIG. collect. The resizing machine is configured to be able to arbitrarily adjust the thickness of the collected pulp, and its mechanism and operation are as follows.

In FIG. 2, 10 is a rotary chain conveyor rotationally driven by a motor 10a, and 11 is disposed above this conveyor, and has a lower surface having a shape that almost matches the shape of the inner surface of the pulped outer skin 3 divided into four parts. 12 is a cylindrical rotary round blade provided near the end of the conveyor, and 13 is a motor for driving the rotary round blade 12.

The pulp A4 husk 3 carried on the conveyor 10 is held down by the holding plate 11 and pushed into the rotary round blade 12 as the conveyor A7 moves, and the tanzak-shaped pulp piece 8 containing no buds is pushed into the rotary round blade 12 by the rotary round blade 12. The scraped pulp pieces 8 remain in the rotary round blade 12, and the skin with the remaining pulp 9 falls from the end of the conveyor into a lower container (not shown). Adjust the position to the height where you can scrape off the pulp of the outer skin 3 so as not to include the buds, and make J5.
<.

The tanzak-shaped pulp pieces (4 pieces can be collected from one pineapple raw chestnut) collected in the above process are finely chopped into appropriate sizes using a food cutter or chopper to produce fruit grains. As for the size and shape of the fruit, it is suitable to have a cubic shape with a side of about 2 ms, but it is not limited to this. It is fine as long as it is something. This shredding operation cuts the long fibers of the pineapple pulp into shorter pieces, which improves the feel of the drink down the throat.

Next, after cutting out the pulp pieces 8 that do not contain buds 9,)
The remaining pulp 9 adhering to the pericarp is scraped off along with the buds 7 using a known radiator and used as a raw material for fruit juice.

The pulp 9 thus collected may be used alone as a raw material for fruit juice, but it is usually combined with broken or torn pulp obtained from the pulp preparation line for canning solid pineapple and cylindrical pulp 2 for canning slices. The bud pulp produced by removing the buds is added to the fruit juice and is used as a raw material for fruit juice. The fruit juice raw material is crushed using a shredder and then put through a juice extractor to squeeze the juice.

The squeezed fruit juice is passed through a known pulper finisher or super decanter to adjust the pulp content to around 6%, and then passed through a centrifuge to reduce the pulp content to 3%.
Adjust as below. This operation also removes all the buds and black seed particles contained in the juice.

The following steps are used to produce a pineapple drink containing fruit grains using the fruit grains and fruit juice prepared in the above steps.

First, a predetermined amount of fruit is stuffed into a washed empty can using a fruit filling machine. The mechanism and operation of the fruit filling machine are outlined below.

FIG. 3(a) is a plan view of the fruit filling machine, and FIG. 3(b) is a view taken along the line AA in FIG. 3(a). In Figure 3, 1
4 is a fruit hopper, 15 is a bottom plate 14 of the fruit hopper 14
Fig. 3 shows the quantitative measurement square forming part placed on a. Quantification First, in the forming part 15, there is a cylindrical granule filling meter with an open bottom.
A suitable number (5 in this embodiment) of 15a are formed. Quantification First, the forming unit 15 moves the bottom plate 1 of the hopper 14 as shown by arrow B in FIG. 3(a) using the handle 15b.
4a can be slid in the front-back direction.

A notch 14b is formed in the hopper bottom plate 14a at the position where the metering forming part 15 is moved back the most, and above the notch 14b, the same number of pistons 16 as the metering forming section 15 are fixed to a rod 17. Each piston 16 has a diameter such that it can fit into the corresponding metering cell 15a, and each metering chamber 15a is in a position where the metering forming part 15 is retracted.
It is placed in a position directly above the , and can be moved up and down via a spring 18 . The can 20 is moved by the runway 19 to a position below the notch 14b of the hopper.

To fill cans with fruit using this filling machine, the fruit is piled up in the hopper 14 and filled into each metering chamber 15a, and then each color 20 is placed directly below the piston 16. After this movement, the handle 15b is pushed in to slide the metering forming part 15 to a position below the piston 16.

As a result of this operation, most of the fruit particles in each weighing box 15a fall into the box 20 due to their own weight. Next, each piston 16 is lowered to forcibly push out the fruit particles firmly attached to the wall surface of the metering chamber 15a and fall into the chamber 20. Can filled with fruit 2
0 is carried out of the filling machine by one runway.

On the other hand, for fruit juice, measure the sugar content and acidity of each batch (in addition, measure the viscosity and acidity of the fruit), add water,
Saccharides and acidulants are added as appropriate to adjust the pulp content ratio, viscosity, and acidity to the desired level.

The fruit juice that has undergone the above adjustment is instantaneously sterilized and heated at 90° C. to 92° C. for 15 to 20 seconds using a flash pass durizer. Thereafter, using a known fruit juice filling device, the sterilized fruit juice is discarded and the fruit particles are filled into the filled can, and the can is immediately sealed.

Once the cans are sealed, they are immediately heated to 90°C in a continuous pasteurizer.
Heat sterilization is performed at ~92°C for 10-8 minutes. Next, the can is placed in a continuous cooler and rapidly cooled to room temperature, and then passed through a heat dryer to remove water droplets attached to the can to obtain a pineapple drink product containing pineapple fruit.

In the pineapple drink containing fruit according to the present invention, the fruit content, which is the sum of the content of pineapple fruit and the fruit juice content, is 25 to 45%, the sugar content is 12 to 13 degrees Brix, and the acidity is 038 to 0.42 ( citric acid%) is suitable.

In the above embodiments, a food can is used as a container for filling the fruit juice and fruit grains, but a sealed container such as a bottle can also be used.

〔Effect of the invention〕

The pineapple drink containing fruit grains produced by the above manufacturing method is different from the conventional product, which is made by mixing canned pineapple crush and canned pineapple juice and heating and sterilizing it again. Because it is made from fresh fruit pulp that has been collected directly from a single fruit and heated only once, it has a fresh flavor and excellent texture that is incomparable to conventional products, and the taste of the fruit and the taste of the fruit juice are different from each other. This product can fully meet the demands of consumers as an excellent drink containing fruit particles.

Further, according to the manufacturing method according to the present invention, pineapple 1
The pulp from the fruit was collected in two steps. First, the pulp pieces that did not contain buds were collected to produce fruit grains, and then the remaining pulp containing the buds was collected for juice extraction. It is possible to completely prevent contaminants such as pineapple buds and seeds from being mixed into the product.

A panel of 20 people tasted the pineapple drink containing fruit grains produced by the above-mentioned production method of the present invention in comparison with pineapple juice made using fruit grains collected from conventional canned pineapple crush. All the panelists agreed that the pineapple drink according to the present invention was superior in both flavor and texture.
