Description

[Detailed description of the invention] The present invention relates to a method for producing spherical solidified bodies.

More specifically, the present invention aims to provide a spherical coagulated body having a diameter of about 30 mm or less, and an upper layer containing a triglyceride and a surfactant that are liquid at room temperature, and a disintegrated product of various alginates of seaweed and an alkali thereof. Natural waste such as polysaccharides, di- or trivalent polyvalent metal salts and/or crustaceans required for viscosity adjustment is added to the coagulating liquid consisting of a lower layer in which the decomposition product is adjusted to a specific gravity of 1.030 or less and a pH of 7.5 to 12. The method is characterized in that a constituent liquid containing an acetic acid decomposition extract of a substance is added dropwise.

The present invention provides a method for producing a spherical solidified body having a liquid or gel-like interior.

Generally, jelly foods are manufactured using solidifying agents such as agar, gelatin, and pectin as the main ingredients, and depending on the purpose, sweeteners, acidulants,
A method is used in which a sol solution in which flavors, colorants, and other supplements are added and dissolved by heating is poured into a mold and cooled to form a gel.

The molded products are mainly cubes, and there are almost no jelly foods solidified into spheres.

This is simply because it was extremely difficult to create continuous spherical shapes.

In nature, there are many spherical objects such as fish eggs and fruits.

The main purpose of the present invention is to produce a coagulated material with properties close to those of natural products as described above for spheres of 87 mm or more, which were difficult to manufacture in the past, and the quasi-purpose of the present invention is to apply this spherical material in various fields. It is said that

Conventionally, methods for obtaining spherical bodies include: 1. Pour a heated and solidified liquid such as agar or gelatin into a mold and cool and solidify it; 2. Pour an aqueous solution of a polysaccharide such as sodium alginate or pectin into an aqueous solution of a metal salt of calcium. The method of solidifying by dropping (submerged dropping method), solidification reaction by thermal denaturation of egg white, starch, gluten, etc. are well known.

Method (2) does not require a coagulant and has the advantage of being able to obtain jelly of any shape depending on the type of mold.

However, it takes a long time to cool and solidify, making it unsuitable for high temperature sterilization.

Method (2) not only yields only small spheres of 7 mm or less, but also has the disadvantage that the texture is impaired because the spheres are hardened to the inside.

Method (■) makes it difficult to maintain a spherical shape. However, the submerged dropping method (2) also has the great advantage of being easy to operate continuously.

In the past, there were three submerged dropping methods: ■ Dripping into cooled oil, ■ Dripping into a bath consisting of an oil layer and an aqueous layer containing calcium salts, and ■ Dripping directly into an aqueous layer containing metal. A method is proposed.

However, these methods do not meet the purpose of the present invention because they cannot produce spheres with a diameter of 7 mm or more, or they harden to the inside.

The object of the present invention is to eliminate such inadequacies and provide a spherical solidified body having a wide range of diameters from 7 to 30 mm and whose interior is liquid or gel-like.

The present invention is a spherical solidified body that is similar to the spherical nature of natural products and is coated with a thin cured film that is resistant to some physical shock, and has a liquid or gel-like interior with a diameter of 7 to 30 mm. Research was conducted to develop a coagulated material and its continuous production method.

Add 2-3 to polysaccharide or gelatin to adjust viscosity.
An internal constituent liquid containing a mixture of polyvalent metal salts or acetic acid decomposition products of natural waste such as crustaceans is dropped onto a triglyceride layer containing a surfactant and a layer of a film-forming liquid whose specific gravity has been adjusted to an appropriate level. As a result, it was found that the desired spherical coagulated body of 30 mm or less, whose interior was a liquid or gel body, could be obtained.

The materials for adjusting the liquid content of the spheres targeted by the present invention include carrageenan, farcellan, tamarind, gum tragacanth, guar gum, gum arabic, gum karaya,
Mention may be made of one or more mixtures of alginate propylene glycol ester, alpha-starch, pectin, gelatin, soluble starch or methylcellulose CMC.

As the coagulant, a mixture of di- or trivalent polyvalent metal salts or acetic acid decomposition products of natural wastes such as crustaceans are suitable.

Other optional ingredients can be added depending on the purpose.

Next, the film-forming substance is brown algae or its purified powder.

The specific viscosity of these seaweed solutions is 4 to 20, and the pH is 7.5 to 1.
Use the one adjusted to 2.

In addition, polyvinyl alcohol, ethyl cellulose, hydroxypropyl methyl cellulose, collagen, etc. can also be used in combination to increase the film strength.

Triglycerides used to form the spheres include acetylated glycerides, single triglycerides, and the like.

Examples of the surfactant include lecithin, silicone oil, sorbitan fatty acid ester, and sucrose fatty acid ester, and particularly preferable is lecithin and sorbitan fatty acid ester with an inner span of 80.

According to the present invention, when producing a coagulum using the above-mentioned substance, first, the specific viscosity of a solution of brown algae or its purified powder is adjusted to 4 to 20 and the pH to 7.5 to 12. A 2% polysaccharide solution was prepared.

This is used as a film forming liquid (hereinafter referred to as the lower layer liquid).
.

The medium for sphere formation is triglyceride (glycerin fatty acid ester single triglyceride that is liquid at room temperature or acetylated glyceride that is liquid at 30°C or higher) with 0.01 to 0.5% surfactant added (hereinafter referred to as (referred to as upper layer liquid).

Content components include polyvalent metal salts (0.1-1%), natural wastes such as crustaceans, or acetic acid decomposition extracts (1-4%).
alone or as a mixture and polysaccharide for viscosity adjustment (0-2%)
Or gelatin (5-20%) and other optional components are included, and this component has a specific viscosity of 1-25 and a specific gravity of 1.00-1.3.
An aqueous solution of 0 is used.

In the production of spheres, the desired spherical amount of the constituent liquid is dropped into the soil layer liquid consisting of triglycerides, which forms a sphere due to surface tension, moves further to the lower layer, and a thin film surrounds the sphere. It is formed.

The coating of the resulting sphere becomes thicker over time as unreacted metal particles gradually diffuse.

If the specific viscosity of the lower layer liquid is 15 or more, the adhesion rate of the spheres will increase due to strong adsorption during film formation, and the entire coagulated liquid will gel depending on the contact time.

When gelatinized, the constituent liquid that is subsequently dropped does not become spherical, but instead becomes amorphous, from a spindle shape to a flattened shape, and finally becomes impossible to form.

Therefore, the coagulating liquid used in the present invention has a specific viscosity of 4 to 20
, an aqueous solution having a polysaccharide concentration of 0.3 to 1.0% can be used as the lower layer liquid.

The obtained spheres are vulnerable to physical impact as they are, so in order to increase their strength, they are introduced into a solution (at 60°C or higher) containing 0.1 to 3% of various calcium salts as a main component, and continuously The strength of the membrane can be increased by immersing it for a predetermined period of time while stirring the membrane.

The spherical membrane thus obtained has been transformed into a thin hardenable membrane free of polysaccharides and metal salts, so it can withstand some physical impact and also has advantages such as heat resistance and storage stability.

Experimental Example 1 Table 1 shows the sphere formation rates conducted using seaweed that had not been subjected to alkaline decomposition.

5 The concentrations of seaweed shown in the table range from 0.3 to 1.0%.

The formation rate refers to the percentage of complete spheres that are separated into individual particles, excluding adhered spheres and irregular spheres, after 3 minutes of reaction after dropping.

The above results show that the yield of normal spheres is low when spheres are formed using seaweed that is not subjected to alkaline decomposition treatment, and that the sphere formation rate is higher when seaweed polysaccharide is used than when using alginate alone.

Experimental Example 2 Table 2 shows the state of the spheres obtained by dropping the constituent liquids into a two-layer bath consisting of a lower layer liquid of seaweed solution with each specific viscosity and an upper layer liquid of triglyceride. (determined after treatment with hot calcium solution).

The strength of the membrane is expressed by the weight required to collapse the sphere.

The adhesion rate of spheres was expressed as the percentage of complete spheres in which each sphere remained independent.

The specific viscosity was calculated using water at 25° C. as 1.

From the results in the table above, the specific viscosity of alkaline-decomposed seaweed is 4.
A range of 12 to 12 is preferable.

Experimental Example 3 The effects of various combinations of two-layer liquids on the state of sphere formation were investigated.

Table 3 shows the state of formation of spheres obtained by dropping the constituent liquids into the baths of each system.

As you can see from the table above, No. A bath consisting of a surfactant-added oil layer and alkaline-decomposed seaweed liquid as described in No. 5 is most suitable for the purpose of the present invention.

Experimental example 4 The concentration of surfactant added to the upper layer was investigated.

To prevent spheres from adhering to each other and to prevent the underlying seaweed from gelling,
This problem can be solved to some extent by using a seaweed liquid with a specific viscosity of 4 to 10 that has been subjected to alkaline decomposition treatment.

However, there are other ways to obtain a perfect spherical shape other than using oil with the interfacial tension of the surfactant adjusted.
It is difficult to obtain the spherical coagulum intended by the present invention.

Table 4 shows the effects of various surfactants.

When no surfactant is added, the formation rate of spindle-like or oblate shapes is high.

To increase the yield of perfect spheres, it is desirable to add Span 80 or 0.03 to 0.2% of lecithin.

The thickness of the coating of the coagulated body can be appropriately changed depending on conditions such as the concentration of the polysaccharide, the degree of polymerization, the concentration of the coagulating solution, and the reaction time.

The specific method is to thermally decompose seaweed with a 0.1 to 0.8% alkaline solution and adjust the specific viscosity to 4 to 10 as the lower layer, and further add 0.01 to 0.2% of the solution at the interface. In a sphere-forming bath consisting of an upper layer of triglyceride in which an active agent is dissolved,
The content constituent liquid having the properties of a specific viscosity of 1 to 20 and a specific gravity of 1.00 to 1.30 is added dropwise to form spheres in the oil, and then moves to the lower layer to form a coagulated body with the sphere surface coated. (The reaction time during this period is 2-3 minutes).

The obtained coagulum was further introduced into a 0.3 to 2.0% hot calcium solution (60°C or higher) and immersed for 4 to 5 minutes to obtain a spherical coagulum consisting of a stable thin film with a hardened surface. It will be done.

This coagulated body has a shape similar to natural fruits such as grapes or natural spherical objects such as fish eggs, and also has a similar texture and physical strength.

The invention will be further illustrated by the following examples.

Example 1 1g carrageenan Sugar 30. g Calcium acetate 5g Alum 3g citric acid 1g Vitamin C 1g Flavor Appropriate amount Coloring agent 〃 Make 1001 with orange juice.

The above formulation is sufficiently dissolved to form a liquid composition.

On the other hand, the upper layer of tricaprin in which 0.05% SPAN 80 was dissolved and the lower layer of a coagulated liquid obtained by heating brown algae to 75°C or higher with a sodium hydroxide solution, dissolving and filtering the liquid, and adjusting the specific viscosity of the liquid to 5. The above-mentioned constituent liquid was added dropwise in 4 ml portions to the sphere forming bath using a quantitative addition device.

The dropwise added liquid forms a spherical shape in the upper layer, and then moves to the lower layer, where the surface of the liquid content first gels, and a spherical coagulated body is obtained.

After reacting for about 1 minute, the spheres are separated from the bath, washed with water to remove excess coagulation liquid on the surface, and then treated for 5 minutes in a 0.5% calcium acetate solution heated to 60° C. or higher.

The obtained spheres with a diameter of 20 mm had a suitably hard surface and a beautiful fruit ball shape.

Example 2 Fercelelan 3g Zelanan 50g Calcium chloride 5g Iron citrate 0.5g Starch syrup
200g Sugar 200g Flavor Appropriate amount Natural pigment Make 1000g with apple juice.

The upper layer of acetylated glyceride, which is liquid at room temperature in which 0.08% lecithin is dissolved, and sodium alginate are thermally decomposed with sodium hydroxide solution at 85°C under salinity, and the specific viscosity is 4.
4 ml of each of the above constituent liquids is added dropwise to a two-layer sphere forming bath consisting of a lower layer and a lower layer.

Fruit balls were obtained according to the method of Example 1 below.

The produced fruit balls were palatable and had excellent texture.

The yield of fruit balls produced in Examples 1 and 2 are as follows.
