Description

Single-use portion packs that come with

a flavored instant beverage product, and method for its production The invention relates to a single portion packet Use that with an instant flavored beverage product, especially one flavored instant coffee product, is filled, and a process for its manufacture such portion packets.

When opening a container or packaging of a beverage product The first developed flavor is of great importance in how the product is viewed by the consumer Is accepted. For example, developed a container that vacuum-packed roasted coffee or contains ground coffee, the first time the can is opened, an aroma is more intense good quality.

Soluble beverage products, such as instant coffee, are usually due to processing extremely poor in flavor.

In particular, portion packs that contain a lot of instant coffee for one time Use included, have minimal initial flavor impact when opened.

To improve the flavor effect of soluble beverage products, Various methods have already been developed. For example, aroma can be used during incorporated into the soluble beverage product during processing. The particular The more common method for instant coffee is to add a flavored oil use. For example, instant coffee can with flavored coffee oil coated or sprayed.

According to U.S. Patent 3,077,405, instant coffee particles are formed of agglomerates coated with flavored coffee oil, and then become the agglomerates are packaged to form a flavored instant coffee product.

US Pat. No. 3,769,032 describes the flavoring of instant coffee with the help of flavored coffee oil by adding drop by drop.

The addition of flavored coffee oil to instant coffee is common satisfactory to improve the aroma qualities of the coffee product. Usually the amount of flavored oil added to the instant coffee is increased, to increase the aromatic effect of the instant coffee product. However, if too much flavored oil is added to the instant coffee product, forms on the beverage level in an oil stain on the cup. This oil stain problem is often referred to as an oily cup " that of many coffee consumers in terms of appearance and in particular Taste of the drink is perceived as unpleasant.

To solve this oily cup problem, several methods can be used be applied. For example, the flavored coffee oil in an inert Carriers are impregnated to serve as a source of aroma. The European patent application No. 1 460 describes a flavored article made from a microporous, cellulosic polymer substrate that is impregnated with flavored coffee oil and is surrounded by a cover with perforations to gradually open a passage of aroma through the wrapping is formed. DE-OS 24 11 323 describes coffee aroma stabilizers for use in special coffee packs, formed from an insert made of paper, cardboard or similar material and with Coffee flavor carriers are impregnated from liquid glycerides. These impregnated Carriers serve to the flavored oil out of contact with the instant beverage product to hold, and are especially desirable if the container or package is repeated several times should be opened.

Single-use portion packs filled with instant coffee but only require a strong aroma effect when opening the packet for the first time, all coffee being poured out. An impregnated carrier as a flavor source a single-use packet would therefore be significantly more expensive mean. In addition, there would be difficulty in preventing the Impregnated carrier falls out of the packet along with the coffee.

There is therefore a need for less expensive and simpler ones Because of the provision of portion packs for single use that are flavored with Instant coffee products are filled.

The invention is therefore based on the object of portion packets for single use, with a flavored instant beverage product, e.g. instant coffee fairy, filled, provide that an enhanced initial flavor effect which do not form an unpleasant oily cup and which do not impregnate Require carrier as a source of flavor.

The invention relates to a portion pack for single use, which is filled with a flavored instant beverage product. A locked one a substantially gas impermeable package contains a predetermined amount of one soluble beverage product, e.g. a soluble coffee product on which less than 0.6% by weight of an edible oil.

The packaging also contains 0.1 to 0.8% by weight, based on the soluble beverage product, a flavor oil, typically a flavored oil, applied to the inner surface of the sealed package. The total amount of Aromatic oil on the inside surface of the package and on the soluble beverage product usually at least 0.4% by weight.

The aromatic oil is first applied to the inner surface of the packaging. Then the predetermined amount of the soluble beverage product is placed in the package given. The packaging containing the flavor and soluble beverage product is then sealed to the sachet of the flavored instant beverage product to obtain.

It has been found that an amount of about 0.6% by weight of flavor oil, e.g. flavored coffee oil, on an instant coffee product to create an unpleasant one oily cup with regard to the appearance and especially the taste of the beverage can lead. The amount of aromatic oil on the coffee product can be reduced to about 0.4% by weight so as not to form an oily cup, but this reduces the flavor effect will.

The application of aromatic oil on the inner surface of the packaging allows an increase in the amount of aroma oil to over about 0.4% by weight with increased aroma effect, without creating an unpleasant oily cup. For example, parcels for single use, which are filled with flavored instant coffee product, 0.6% by weight of coffee oil, with 0.45% by weight of flavored coffee oil on the Inside surface of the packet will be injected and 0.15% coffee oil will be on the soluble Cofieproduct. When water is added to the contents of the packet, to To get the coffee drink, only about 0.4 wt .-% of the total amount of oil comes together with the instant coffee out of the packet. That way will the formation of an unpleasant oily cup is avoided, and the aromatic effect of the Package for single use is increased.

An important part of the present invention consists of the packaging that contains the flavor oil and the soluble beverage product. This here used expression "packaging" includes various containers, such as e.g. bottles, flasks, cans, pouches, sachets, envelopes, etc. because of what is contained therein Aroma oil, the packaging should be essentially gas-impermeable when it is closed is. As used herein, "substantially gas impermeable" means that the packaging prevents loss of the flavor contained therein, while at the same time the entry of oxygen is prevented, which can cause the aroma to become dull will.

The entire packaging can be made of essentially gas-impermeable Material to be made. However, it only takes one layer of packaging inside to be essentially gas impermeable.

For bottles, flasks and cans that are usually rigid or semi-rigid The packaging can be made from materials such as glass or metal, which are essentially are gas impermeable, are formed. The packaging is used for bags, pouches and envelopes usually preferably formed from more pliable materials. To the appropriate Flexible materials include metal foils, e.g. aluminum foils, which are essentially are impermeable to gas, as well as films made of polymers and copolymers or mixtures including laminates thereof.

Suitable polymer films include those made of polyethylene, polypropylene, Polyvinylidene chloride and polyvinyl chloride.

Preferred polymer films are those that are hot on the inner layer are sealable to form the package. Because polymer films are usually gas-permeable are, a substantially gas-impermeable one becomes in the manufacture of the packaging Layer inserted. For example, a suitable laminate packaging can be made an inner layer made of heat-sealable polymer film, e.g. made of polyethylene or Polypropylene, a second layer of aluminum foil that is essentially gas impermeable is made of a third layer of polymer film and an outer layer of paper will.

Another important part of the present invention is that soluble drink product. Soluble beverage products useful in the present invention are useful are those which, when dissolved in water, are substantially water-soluble are and form a watery drink. The soluble drink products can be of natural ones Fruit juice powders, synthetic drink mixes or combinations derived therefrom be.

For example, in the present invention, orange powder, Powder made from lemon juice, lemonade powder, grape powder, tea powder, cocoa powder and the like.

Also soluble beverage products derived from roasted grains, such as e.g. from sprouted barley, rye, maize and chicory or from mixtures thereof, can be used.

The commonly used soluble drink product according to the present invention Invention is a soluble coffee product.

The soluble coffee product can be caffeine-free or non-caffeine-free and can be in the form of spray-dried particles, freeze-dried particles or combinations thereof. Optionally, the soluble coffee particles be agglomerated. US Pat. No. 3,652,293 describes particularly from column 7, line 42 to column 9, line 9 method for agglomeration of soluble coffee particles.

The coffee particles can also be in the form of instant coffee flakes. U.S. Patent No. 3,625,704 describes soluble coffee flakes which are made more soluble by grinding Coffee particles are formed by means of rollers. The flaky soluble coffee product usually forms about 30 to 70% by weight of the total amount of soluble flakes. The most important feature of the present invention is the amount of edible oil, especially flavor oil, on the soluble beverage product to a minimum restrict. A soluble coffee product containing 0.6% by weight of coffee oil forms an unpleasant oily Cup when water is added. A soluble coffee product containing no more than 0.4% by weight of coffee oil is satisfactory in terms of the oil content in the beverage product. At a A soluble coffee product that contains fluffy soluble coffee is commonly known as coffee oil incorporated in an amount of up to 0.15% by weight, based on the total amount of coffee.

Another important part of the present invention is the aromatic oil. As used herein, the term "flavor oil" refers to edible oils derived from Contain naturally desired flavor components or to which flavor components have been added became.

The term "edible oils" usually refers to animal ones or vegetable triglycerides such as soybean oil, rapeseed oil, cottonseed oil, marine animal oils and lard. However, oils obtained from other food products, such as fruits that have been removed or squeezed. A special one preferred edible oil for instant coffee products of the present invention is coffee oil, which naturally contains aromatic components.

Usually the edible oil is enriched with aromatic components, a flavored oil, a flavor oil preferred according to the present invention, to build. For a soluble coffee product, there is a preferred one that is flavored flavored coffee oil. Flavor Ingredients Made With Soluble Beverage Products can be derived from many sources. For example, can Desired roast bean beverage flavor, including coffee and kaqa beans, Nuts such as peanuts and fruits such as strawberries, oranges, grapes, Lemons and the like. Synthetic beverage flavors can also be used according to The present invention can be used.

In the case of a soluble coffee product, coffee flavor is preferred Source for the fortification of edible oil, the coffee aroma being different Sources can be derived. For example, coffee aroma can be used during processing of coffee with roasting and grinding from gases obtained during the Roasting, grinding, flocculation, forwarding of the mass and other processing stages escape. When processing an instant coffee product, coffee aroma can occur during the dry or steam distillation of roasted and ground coffee beans, including desorbed volatiles contained in the US Pat. No. 3,717,472, 3 997 685 and 4 100 305 processes described, or from extraction stripping condensate, stripped coffee oil or similar sources.

A preferred source of coffee aroma is grinder gas.

The term "mill gas" as used herein means those volatile aromas and flavors that occur during and after the grinding of roasted coffee beans are released. Preferably the mill gas is from the gas that is withdrawn directly from the grinding plant, but it can also be gas from other sources such as flocculators and coffee silos. This Gas is preferred because it is the richest and most intense source of those coffee aroma ingredients which are most wanted by the consumer.

To enrich the edible oil with the desired beverage flavor various methods can be used. For example, coffee aroma usually condensed as an aroma cold condensate at cryogenic temperatures, for example using a scraped wall heat exchanger (scraped wall heat exchanger). GB-PS 1 339 700 describes a process for the production of Coffee aroma cold condensate using scratch wall heat exchangers. The educated Aroma cold condensate is then added to the edible oil. U.S. Patent 3,783,163 describes a process for flavoring edible oils by adding the oil to a cryogenic liquid (cryogenic fluid) with the formation of a slurry, addition of an aroma cold condensate to the slurry and subsequent evaporation of the cryogenic liquid, leaving a residue of the flavored oil. The beverage flavor can also be condensed directly into the edible oil or added directly to the edible oil will.

According to US Pat. No. 3,823,241, a preferably cooled to -101tC, crushed edible oil under such pressurized conditions as to add flavor to the crushed conveying oil, brought in connection with roast and ground coffee.

In the method of the present invention, preformed packages can be used. When using flexible materials, however, is usually the packaging shortly before the addition of the aroma oil and the soluble beverage product shaped. For example, a sheet of flexible packaging material may be of length after being folded and closed at the side. The folded and side-locked Web is then cut into individual packages. U.S. Patents 3,700,388 and 2,649,611 describe machines and processes for forming individual packages from a sheet of flexible material.

In the process of the invention, the flavored oil is applied to the inner surface applied to the packaging before the soluble beverage product is added. Through this, that the aroma oil is applied first, the aroma effect of the packaging when open increases. To the useful procedure to apply the Aroma oils include coating, injecting, spraying or brushing on the Aroma oil on the inner surface of the packaging. A typical method of application consists of injecting the aromatic oil onto the inner surface of the package with a Spray system under exclusion of air. Suitable spray systems without air are those which are usually used in paint spraying processes.

U.S. Patents 3,635,125 and 3,827,339 describe spray systems without Air commonly used in paint spraying processes.

The amount of aromatic oil that is applied to the inner surface of the package depends on the desired degree of flavoring, the amount of aromatic oil on the soluble coffee product that is poured into the package, etc. The most important factor is to make sure that it is on the inside surface of the Aromazpl applied to the packaging together with the on the soluble beverage product existing edible oil does not cause an unpleasant oily cup formation, though the packaging is opened and the contents poured out. In general, the Amount of aroma oil applied to the inner surface of the package about 0.1 to 0.8% by weight, based on the soluble beverage product. Preferably, O, 4 Up to 0.5% by weight of flavored coffee oil is injected onto the inner surface of the packaging, when the soluble beverage product is a soluble coffee product. Also through the Application of the aromatic oil on the bottom of the inner surface of the package becomes the problem oily cups when opening the package and pouring the contents to a minimum degraded. In order to achieve a strong initial aroma effect, the Total amount of aromatic oil on the inner surface of the packaging and on the soluble Beverage product, which is added afterwards, usually at least about 0.4% by weight and more suitably at least about 0.6% by weight.

Also the amount of the aromatic oil is on the inner surface of the packaging usually greater than the amount of flavor oil on the soluble beverage product.

After adding the aromatic oil, the packaging is made with a predetermined Amount of the soluble beverage product filled.

As used herein, the term "predetermined amount" refers to the amount of soluble beverage product required to be added upon addition Water to form one serving of the drink. One serving is expediently one soluble coffee product about 1 to 3 g. When filling the soluble beverage product Various filling devices can be used in the packaging.

Fig. 5 of U.S. Patent 3,619,975 and Fig. 6 of U.S. Patent 3,708,952 describe Filling devices for packaging beverage products. The in Fig. 6 of U.S. Pat No. 3,708,952, the drill-like shaft 37 shown facilitates flow of the product during of the filling process. When the soluble beverage product is agglomerated, a smooth, tapered, or straight shaft such as that shown in Figure 5 of U.S. Patent 3,619,975 Shaft 67, preferably to prevent the agglomerates from breaking up. Instead of this the filling device can also be set in vibrating movements in order to Initiate flow of the soluble beverage product. After adding aromatic oil and soluble beverage product, the packaging can be sealed. Possibly A tear-off slot can be formed to make packaging the product easier is to be opened.

Preferably, the steps of adding flavor oil and soluble Beverage product and the sealing of the packaging in the method according to the invention carried out under inert gas. To the suitable inert gases, which can be used to maintain an inert gas atmosphere Carbon dioxide and nitrogen. The packaging is preferably also closed in such a way that that it contains an inert gas atmosphere.

A preferred method of making the flavored beverage product filled packet is shown in U.S. Patent Application Ser. No. No. filed on September 2, 1980. 183 551 described by Thundathil. In the process of this patent application will be the addition of the aromatic oil and the soluble beverage product and the sealing stage carried out in a non-polar inert gas atmosphere. The non-polar inert Gas atmosphere is applied to the amounts of oxygen and carbon dioxide to keep a minimum. As used herein, non-polar inert gas " refers to an inert gas that when adsorbed onto the soluble beverage product remains unpolarized. Suitable non-polar inert gases include Noble gases such as argon. For convenience, nitrogen is considered to be non-polar inert gas is preferred because of its cost and commercial availability.

In the method of US patent application 183 551, the packaging before adding flavor oil and soluble beverage product with a non-polar one purged inert gas. This rinsing stage ensures that the packaging is minimal Contains amounts of oxygen and carbon dioxide. After the rinsing stage, the aroma oil is given to the packaging. The soluble beverage product is usually made with a stripped non-polar inert gas, expediently for a period of at least about 30 minutes before adding it to the package. This stripping stage is used In addition, the amounts of oxygen and carbon dioxide that are on the soluble beverage product be absorbed or on the soluble beverage product be liable, to reduce. Conveniently, the stripped soluble beverage product contains adsorbs less than 1 volume percent oxygen and less than 0.05 volume percent carbon dioxide.

A nitrogen stripped soluble coffee product can be a adsorbed oxygen amount below 0; 5% and an adsorbed amount of carbon dioxide below 0.01 8 included.

In the process of US patent application 183 551, the packaging can be according to the addition of the aroma oil and the soluble beverage product is then closed will. The closing or sealing step is carried out so that the sealed packaging a non-polar inert gas atmosphere with an oxygen content contains less than 1% and a carbon dioxide content of less than 0.05%. For instant coffee products however, oxygen levels below 0.5% and carbon dioxide levels below 0.01% can be obtained. The minimum amount of carbon dioxide prevents adsorption of the Aromas on the soluble beverage product and thus increases the aromatic effect of the packaged Product when opening.

A useful device for carrying out the invention Process is a gas packaging machine with intermLtting Bartelt movement (IM model no. 7) with a filling device, model D, produced from Rexham Corp. in Sarasota, Florida, USA.

This Bartelt machine is similar to that in U.S. Patent 4,700,388, in particular Fig. 2, described machine.

The device for carrying out the method according to the invention is therefore described with reference to Figure 2 of U.S. Patent 4,700,388. Variations of the Apparatus for performing the method according to the invention are then described.

The device for carrying out the method according to the invention, 2 of US Pat. No. 4,700,388, in particular, includes a shaping section 37 the packaging and a section 39 for filling the packaging. In section 37 is a sheet 30 of laminate film is drawn forward and along its bottom edge folded to form side strips 49. This web 30 is by cooperating Rollers 66 and 67 pulled forward. The toe of these cooperating rollers 66 and 67 is controlled by a photoelectric device (not shown), the markings on the strip 49 felt. When the photoelectric device Sensing these marks, the rotation of rollers 66 and 67 is instantaneous for one fixed period of time, -the implementation of various sealing and cutting processes on track 30 enabled, stopped.

When the strips 49 move forward, two move (not shown) heated horizontal locking brackets in engagement with the strips 49 towards and here to form a bottom lock. After the bottom lock is made is and the strips 49 are moved further forward by the rollers 66 and 67, two heated vertical wear bars 50 move into engagement with the strips 49 back and forth to form a side lock. After the bottom lock and the side closures are formed, becomes the leading edge of the strip 49 moved further forward. beyond rollers 66 and 67 and through the cutting station 55 cut along the side closures to enclose the packaging 32 with two sealed edges to form. In section 37 for shaping the packaging a splitter tongue 53 keeps the upper edge of the strips 49 spread apart when the Bottom lock and the side lock are formed.

The cutting station 55 is located at the end of the section 37 for shaping the packaging. At point 56, the section 39 for filling the package begins, the package 32 is transported to a pair of finger clips that carried by an endless conveyor belt 57 and one edge of the package formed and hold the packaging upright. A splitter tongue, the length of which is somewhat shorter than that shown in Fig. 2 of U.S. Patent 4,700,388 under no.

54 holds the top edges of the packages 32 open stretched. In the device for carrying out the method according to the invention this splitter tongue also has a channel with an opening in the bottom of the Tongue is connected. When the upper part of the package 32 is under the opening the cleavage tongue is a lot of nitrogen gas with a pressure of 1.35 up to 2.74 ba-r fed through the channel and injected into the packaging.

The injected nitrogen gas is primarily used to the package inflate by this point in a substantially flat shape.

US Pat. No. 3,708,952, particularly FIG. 5, shows splitting tongues with channels formed therein through which nitrogen gas is used to open flat packs is fed. After the package has been inflated with nitrogen gas at the end of the splitter tongue a splitting knife (not shown) in a downward direction Way back and forth to open the package wider, and then up withdrawn. The upper part of the opened package is then passed through the conveyor belt 57 moved under a nozzle (not shown). Nitrogen gas is pressurized from about 1.35 to 2.74 bar to the nozzle and into the opened package injected.

The primary purpose of this injected nitrogen gas is residual oxygen and carbon dioxide from inside the package flush out.

After purging with nitrogen gas, the upper part of the packaging becomes by the conveyor belt 57 to a position below a second (not shown) Nozzle moved. This second nozzle is made with the help of a spray system, which is below Air exclusion works, e.g., Model 25B manufactured by Nordson Corp. in Amherst, Ohio, USA, a supply of flavored oil, e.g. pumped from flavored coffee oil.

The flavored oil flows through the second nozzle and then back in the reservoir and in this way forms a circulation system 635 125 describes similar spray pump systems with the exclusion of air. When the upper Part of the package is under this second nozzle, a solenoid is energized. Then the second nozzle opens, and a predetermined amount of flavored oil is injected into the packaging at a pressure of about 24 to about 52 bar.

The second nozzle is preferably set so that the oil on the Bottom part of the inner surface of the packaging is guided.

After the flavored oil is injected into the package, the upper part of the packaging is placed under the filling device 61 according to FIG. 2 U.S. Patent 4,700,388.

At this point the package 32 is through the filler 61 with a predetermined amount of a soluble beverage product, e.g. instant coffee product, filled. In the device for performing the method according to the invention is the filling device 61 is similar to that in US Pat. No. 3,708,952, in particular in FIG. 6 shown. From a filler neck 34 (part of which is shown in FIG. 6) Instant coffee product supplied through the outlet pipe 39. The coffee product in the tube 60 falls on a disc 41, which is replaced by a smooth, tapered shaft in Fig. 6 shown drill-like shaft 37 is rotated so that the coffee product is thrown from the disc outwards into the collector 35. The coffee product in the Collector 35 is then emptied through the spout 36 into the packaging.

About the remaining amounts of oxygen adsorbed on the coffee product and to reduce carbon dioxide, nitrogen gas is released through a hole or holes in it Filling spout 34 at a speed of 28.3 to 425 l / min. fed.

This nitrogen gas circulates through the filler neck to remove any remaining Stripping oxygen and residual carbon dioxide from the coffee product.

After the packaging is filled with coffee product, the top End of the package through the conveyor belt 57 under a wiper blade (not shown) transported, which rotates around a horizontal shaft. The two ends of the rotating Wiper blades remove coffee particles that run along the top edge of the packaging may be present and cause difficulties in the formation of the upper seal could lead. After the top edge of the packaging is wiped off, the Packaging transported between two heated horizontal locking brackets 63, which engages the top edge forming a lock at the top the packaging can be moved back and forth. After the closure is formed at the top the package is transported further between two similar cooling rails 64, which harden the newly formed closure at the upper end.

The sealed packages are then removed from the conveyor belt 57.

In the device for carrying out the method according to the invention encloses a hood (not shown) that shown in Fig. 2 of U.S. Patent 4,700,388 Device from a point just in front of the cooperating rollers 66 and 67 bis to a point just after refrigerator 64. Nitrogen is circulated through the hood passed to form an inert gas atmosphere. This inert gas atmosphere sets keep the amounts of oxygen and carbon dioxide to a minimum.
