JPH07121200B2 - Edible film that disperses easily in water - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a supplementary food having a shape such as powder, particles, flakes, etc., such as a film containing spices, seasonings, condiments and the like. , When it comes into contact with hot water or water,
The present invention relates to an edible film that separates and releases these supplements into the original shape, and the main use thereof is as a supplement for instant foods.

<Conventional technology> Instant food such as a system that can be eaten immediately by pouring hot water on the table or immediately putting water in a food set contained in a heat-resistant container such as aluminum foil and heating the container There is a remarkable spread, mainly noodles and cooked rice, but the number and variety of products are expanding.

In most cases, seasonings and spices are separately packaged in sachets such as polyolefin and moisture-proof cellophane, and the consumer needs to take them out of the container, break the sachet, and return the contents to the container. Although it is convenient to adjust the amount of seasonings and spices according to consumer preference, the majority of consumers have trouble getting their hands dirty when tearing a bag and having trouble cleaning up excess bags. is there.

<Means for Solving Problems> A large amount of fibrous substances such as cellulose, chitin and chitosan are naturally present. Particularly, purified cellulose has a long industrial history, but chitin and chitosan are also purified products in recent years. Is manufactured industrially. Although these natural fibers are insoluble in water, they can be beaten and suspended in water to form a slurry, which can be formed into a sheet by a papermaking method.

More recently, a method for microfibrillating cellulose fibers by a special method has been developed.

It suspends cellulose fiber in water and at least 200 kg /
By passing through a small-diameter orifice with a pressure difference of cm ² and colliding with the vessel wall at high speed and rapidly decelerating, it gives shearing force to the fiber.By repeating this operation, cellulose fiber can be converted into microfibril units. It is divided into (Japanese Patent Publication No. 60-3855).

A Gaulin homogenizer is a suitable device for performing this process.

Such microfibrillation of fibers can be applied to chitin or chitosan as well.

It has been found that microfibrillated cellulose, chitin and chitosan can be eaten as so-called dietary fiber and have a good mouth feel. The microfibrillated fibers also form a dense film when cast from suspension.

On the other hand, we have found that the film obtained in this way is water resistant and does not easily disintegrate in water, but when water-soluble polyhydroxy compounds such as sugars, CMC and pectin are coexisted in the suspension, It has been found that the rolled film has the property of easily disintegrating when immersed in water and becoming the original suspension.

We have microfibrillated cellulose, chitin,
In the presence of a polyhydroxy compound in a suspension such as chitosan, powdered, particulate, flaky foods, etc. are mixed and cast and dried in a mixed state to obtain a film containing the food, and the film is water. It was found that it has the property of easily disintegrating and re-releasing food when soaked in.

<Structure of the Invention> The present invention relates to an edible film easily dispersed in water, which comprises microfibrillated water-insoluble natural fibers and a polyhydroxy compound as a binder.

As the water-insoluble natural fiber, cellulose, chitin or chitosan can be used. The polyhydroxy compound can naturally be selected from among the edible substances for the purposes of the present invention. Examples thereof include starch, dextrin, glucose, sucrose, pectin, agarose, carboxymethyl cellulose, pullulan and the like. Of these, those contained in natural foods do not necessarily have to be used in a purified form, and those containing them as a main component may be used.

For example, rice flour, wheat flour, bean flour or the like may be used instead of starch.
Alternatively, those polyhydroxy compounds containing amino acids and proteins, which can be powdered by dehydrating it,
For example, it may be soy sauce, sauce, seasoning such as miso, and the like.

An object of the edible film of the present invention is to provide it as a product carrying spices, seasonings, condiments and the like. Examples of spices and condiments that can be applied to the present invention include those obtained in a dried and small particle form such as chili, pepper, sesame, cinnamon, garlic, green onion, laurel, saffron, wasabi and ginger. In this case, wasabi and ginger correspond to sliced plants, but the present invention can also use those grated with a grater.

In addition to the above-mentioned soy sauce, sauce, miso, etc.,
It is in a broad sense including powders and small pieces such as kizushibushi, dashijako, dried shrimp, and kombu which contain a large amount of seasoning ingredients, and these can also be formed into a film according to the present invention.

The amount of the caking agent in the edible film of the present invention varies depending on the type of food, but is preferably about 1 to 10% with respect to the food.

The microfibrillation of water-insoluble fibers can be obtained as a suspension of microfibrillated fibers by treating an aqueous suspension of fibers with a specific method. And foods are added and mixed, and the mixed solution is cast and dried to obtain a film. Further, a polyhydroxy compound may be allowed to coexist when the aqueous suspension of fibers is treated to be microfibrillated.

<Effects of the Invention> The edible film of the present invention can be provided with a seasoning, a spice, a condiment or the like separately or in combination and provided as a supplement to an instant food. That is, in addition to instant noodles, instant porridge, etc., it is convenient because it can be used as ochazuke, etc., and it can be used immediately for edible tea, and it is also possible to adjust the amount by individual consumers. To provide materials that enrich the

The present invention is described below with reference to examples, but the present invention is not limited thereto.

Example 1. 20 g of pullulan (made by Hayashibara Biochemical Research Institute) having a molecular weight of about 200,000
Was dissolved in 1000 ml of water, and 10 g of powder obtained by crushing paper was added and suspended. Homogenizer suspension (Gaulin)
15M-8TA) and passed through it 25 times under a pressure of 420 kg / cm ² to obtain a suspension of microfibrillated cellulose containing vullan.

To the suspension of microfibrillated cellulose / pullulan, 70 g of dried cod roe, 20 g of dried laver powder, 5 g of salt, and 3 g of sodium glutamate mixed with 1000 ml of water were added and mixed, and then cast and dried on a polyester film substrate. And made a film.

The obtained dry film easily disintegrates with water or hot water,
Since it released tarako and dried laver powder, it was suitable for Ochazuke.

Example 2 20 g of paper powder was suspended in 1000 ml of water, charged in a homogenizer, and passed through 30 times under a pressure of 300 kg / cm ² to obtain a suspension of microfibrillated cellulose.

400 g of miso (water content: 52%) dissolved in 1600 ml of hot water was mixed with the above microfibrillated cellulose suspension, followed by casting and drying to obtain a dry film containing miso. The obtained dry film was suitable for miso of instant miso ramen.
