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.For this reason, fruit drinks containing fruit particles such as tangerine juice mixed with tangerine cane are being introduced. tends to be accepted by the world.

Regarding pineapple, there is a conventional canned beverage that is made by mixing pineapple juice (juice concentration 20-25%) with about 5% canned pineapple crumbs (canned pineapple crumb pulp cut into thin pieces with a chopper).

[Problems to be solved by the invention]

This conventional pineapple fruit-containing beverage is made by first canning and heat-sterilizing pineapple crumbs, then mixing them with pineapple juice, filling them into empty cans, sealing them, and sterilizing and heating them again. The fruit juice is poor in flavor, the pulp is soft, and the texture is poor, and as a fruit juice-containing fruit drink that aims to satisfy both the taste of eating fruit and the taste of drinking fruit juice, it cannot fully satisfy the texture of consumers. It was hot.

Therefore, the object of the present invention is to eliminate the drawbacks of the above-mentioned conventional beverages containing pineapple fruit, and to provide a pie containing pineapple fruit that is blended with pineapple fruit and has a fresh flavor and good texture that are almost the same as fresh pineapple fruit. The purpose of the present invention is to provide a method for producing nutpull drink.

[Means of invention to solve problems]

The present invention achieves this object by first extracting a piece of pulp that does not contain any buds from the pulped skin that remains after removing the cylindrical pulp for manufacturing canned slices from a fresh pineapple fruit, and then cutting the pulp piece into small pieces. While producing a large number of pineapple fruit grains, the pulp including the buds is collected from the remaining pulpy skin,
Pineapple fruit juice is prepared by mixing it with pulp pieces obtained in other processes or by squeezing the pulp containing the buds, and filling a container with a predetermined amount of pineapple fruit particles obtained in the above process. After that, the pineapple juice obtained in the above step is instant heat sterilized and then filled.
The container is then sealed and sterilized by heating.

[Effect]

This makes it possible to blend the pulp directly collected from fresh pineapple fruits into fruit grains while preventing the contamination of contaminants such as pineapple buds and seeds, and further maintains the freshness of fresh pineapple fruits 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.

Figure 1a shows a cross section of a fresh pineapple fruit 1 with the top and bottom cut off. The raw materials for the fruit grains and fruit juice of the pineapple drink containing fruit grains used in the method of the present invention are those remaining after removing the cylindrical pulp for sliced canning 2 (FIG. 1b) from the fresh pineapple fruit. Use peel 3 with pulp. Pineapple fresh fruit is the first grade fresh fruit (fruit diameter
124m/m or more) is appropriate.

At the interface between the inside of the outer skin 4 of this pericarp 3 with residual pulp and the residual pulp 5 (indicated by line 6), there is a so-called bud 7.
There are many buds, and these buds contain tiny black seeds. If these seeds are mixed into a beverage, they turn into black fine suspended particles that impair the appearance and texture of the beverage, significantly reducing its commercial value as a beverage. Moreover, since these buds are very small, it is impossible to completely remove them manually if they get mixed into the pulp, 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 jujuice production from the pulped husk, 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 does not become part of the pulp. It is undesirable to collect it by adhering to it.

Therefore, in the present invention, a resizing machine as 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 pulped outer skin 3 is divided into four parts as shown in FIG. The part 8 that does not contain the middle bud 7 is collected as a tanzak-shaped pulp piece. 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 a lower surface arranged above this conveyor and whose shape almost matches the shape of the inner surface of the pulped outer skin 3 divided into four parts. a restraining plate whose position is adjustable in the vertical direction;
2 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 pulped rind 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 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 container (not shown) below. The position of the rotating round blade 13 is adjusted to such a height that it can scrape off the pulp of the fleshy rind 3 without including any buds.

The tanzak-like pulp pieces collected in the above process (1
(4 pieces can be collected from each fresh pineapple fruit) are cut into appropriate sizes using a food cutter or chopper to produce fruit grains. The size of the fruit,
The suitable shape is a cube with a side of about 2 mm, but the shape is not limited to this, and any cubic or nearly cubic shape with a side of about 1 mm to 9 mm may be used. Through this shredding operation, the long fibers of the pineapple pulp are cut into short pieces, which improves the feel of the drink down the throat.

Next, after cutting off the fruit pulp pieces 8 that do not contain buds, the remaining pulp 9 adhering to the pericarp is scraped off along with the buds 7 using a known eradicator and used as a raw material for fruit juice.
The pulp 9 collected in this way may be used alone as a raw material for fruit juice, but it is usually combined with broken or torn pulp obtained from a pulp preparation line for canning solid pineapple fruit and cylindrical pulp 2 for canning slices. The pulp of the buds produced by removing the buds is added and used as a raw material for fruit juice. The fruit juice raw material is crushed using a shredder and then put through a juicer 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 adjust the pulp content to 3% or less. 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. 3a is a plan view of the fruit filling machine, and FIG. 3b is a view taken along the line A--A in FIG. 3a. In Figure 3,
Reference numeral 14 indicates a fruit hopper, and 15 indicates a metering box forming portion placed on the bottom plate 14a of the fruit hopper 14. A suitable number (5 in this embodiment) of cylindrical fruit-filling measuring cells 15a with an open bottom are formed in the measuring cell forming portion 15. The metering cell forming portion 15 can be slid back and forth on the bottom plate 14a of the hopper 14 as shown by arrow B in FIG. 3a using the handle 15b. A notch 14b is formed in the hopper bottom plate 14a in the retracted position even though it has the metering cell forming portion 15, and above the notch 14b there are the same number of pistons 16 as the metering chambers.
is fixed to the rod 17. Each piston 16
has a diameter that allows it to fit into the corresponding metering cell 15a, and is located directly above each metering cell 15a when the metering cell forming part 15 is retracted, and the spring 18 It can be moved up and down via. 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,
Stack the fruit grains in the hopper 14 and measure each amount 1
After filling the cans 5a with fruit grains and moving each can 20 to a position directly below the piston 16, the handle 15b is pushed in to slide the metering chamber forming part 15 to a position below the piston 16. As a result of this operation, most of the fruit particles in each metering chamber 15a fall into the can 20 due to their own weight. Next, each piston 16 is lowered to forcibly push out the fruit particles adhering to the wall of the metering chamber 15a and drop them into the can 20. The can 20 filled with fruit grains is carried out of the filling machine by a runway 19.

On the other hand, the sugar content and acidity of fruit juice are measured for each batch (the sugar content and acidity of the fruit grains are also measured), and water, sugars, and acidulants are added as appropriate to achieve the desired pulp content ratio, sugar content, Adjust to acidity. After completing the above adjustment, the fruit juice is instantaneously sterilized and heated at 90°C to 92°C for 15 to 20 seconds using a flash pasteurizer. Thereafter, the sterilized fruit juice is filled into the can, which has already been filled with fruit, using a known fruit juice filling device, and the can is immediately sealed.

Immediately after the can is sealed, it is heat sterilized using a continuous pasteurizer at 90°C to 92°C for 10 to 8 minutes. Next, the can is placed in a continuous cooler and rapidly cooled to room temperature, and then passed through a hot air dryer to remove water droplets attached to the can to obtain a pineapple drink product containing pineapple fruit.

In the pineapple drink containing fruit particles 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%, and the sugar content is 12 to 13%.
Brix degree and acidity of 0.38 to 0.42 (citric acid%) are suitable.

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

〔Effect of the invention〕

The pineapple pulp drink produced by the above manufacturing method differs from conventional products in which canned pineapple crumbs and canned pineapple juice are mixed and heat-sterilized again. Because it is made from fresh fruit pulp that has been collected directly from fresh fruit and has only been heated once,
The product has a fresh flavor and excellent texture that are incomparable to conventional products, and can fully meet consumer demand as an excellent drink containing fruit particles that combines the taste of fruit and the taste of fruit juice.

Furthermore, according to the production method of the present invention, the pulp from the fresh pineapple fruit is divided into two parts, and the pulp pieces that do not contain buds are first collected to produce fruit grains, and then the pulp that contains the remaining buds is collected. Since the fruit is collected and used for squeezing, it is possible to completely prevent contaminants such as pineapple buds and seeds from contaminating the product.

Regarding the pineapple drink containing fruit pulp produced by the above-mentioned production method of the present invention, a panel of 20 people compared pineapple juice drink using fruit grains collected from conventional canned pineapple pulchritude. When a comparative tasting was conducted, all the panelists agreed that the pineapple drink according to the present invention was superior in both flavor and texture.
