Description

Method for manufacturing edible adhesive for manufacturing disposable containers {Manufacturing method for food glue by used disposable bowl}

The present invention relates to a method for manufacturing an edible adhesive for manufacturing a disposable container.

The use of disposable to multi-use containers has many environmental, social, and economic impacts in real life.

The government regulates that synthetic resin cannot be used for single-use containers, but multi-use containers are not regulated. Therefore, even multi-use containers may be discarded regardless of the number of times of use if the price of the container is very low, so avoid government regulations. It is only a means of harm, and in reality, the distinction between disposable and multi-use is not environmentally and socially different.

Therefore, some of the disposable containers and multi-use containers have environmental problems that affect the environment at the time of disposal and social and economic problems of having to dispose of the waste.

In general, disposable or multi-use containers regulated by the government can be classified into paper cups used in vending machines, synthetic resin cups made of polyethylene, ramen cups made of foamed resin, square trays made of foamed resin, and plates made of foamed resin.

Except for the cups made of polyethylene, they can be said to be disposable, and the polyethylene cups are also a means to circumvent government regulations, but they have the same problems as the disposable containers because they are generally used only once.

In order to avoid government regulations, there are cups made of starch, but since starch is a water-soluble substance, it cannot be used as a container that needs moisture proof, so there is a problem in its use. However, since polyethylene is difficult to biodegrade, it could be said to fall under government regulations, and paper, etc. is coated with polyethylene to produce cups, plates, trays, etc., but this also falls under government regulations, and its strength is remarkably low. Therefore, there was a problem that the function of the container could not be fully demonstrated.

There are cases in which a container is composed of a mixture of starch and biodegradable synthetic resin, but the technology for producing biodegradable synthetic resin inexpensively has not yet reached, and there are limitations in implementation and distribution for disposable use due to the increase in the cost of the container.

In general, the basic material of disposable paper straws or disposable containers is made of paper material that can dissolve in water, and since it is difficult to manufacture the set shape of disposable paper straws or disposable containers with one piece of paper, multiple paper materials are used. After bonding to each other and forming a certain thickness, should it be manufactured in a set shape?

The development of an adhesive for attaching the plurality of papers to each other is required, especially

Since eco-friendly paper straws or containers are products that people eat, it is also required to develop an edible adhesive that is harmless to people.

Hereinafter, with reference to FIG. 1 and FIG. 3, the manufacturing process of the edible adhesive of the disposable container according to a preferred embodiment of the present invention will be described in detail.

Agar-agar, which is used as an eco-friendly material of the present invention, is mainly used as a raw material for agar, and is rich in dietary fiber and low in calories, so it is a well-being food suitable for today's health-conscious age.

Agar-agar is a seaweed belonging to the red plant plant Agar-agar, and agar-agar is a perennial seaweed and has a breeding season in summer. It is mainly distributed in the east coast, south coast, and outer islands of the Yellow Sea, but the ones located in the southern coast of the East Sea are the most produced if the quality is good.

In other words, agar-agar is good if it is produced in the southern coast, and it is usually grown in May-June and harvested in April-June, accounting for about 30% of the total seaweed production. Agar is known to have a variety of beneficial health effects in the body because it is low in calories and contains minerals such as iodine and potassium.

Even if put into drinking water, agar-agar of this nature is not harmful to the human body at all, rather, it is beneficial to the body, in particular, it is easily melted even if discarded after use of the container, and the melted agar-agar has an effect of not harming the environment at all.

In addition, sodium alginate is a food additive for increasing the tackiness and viscosity of food, improving emulsion stability, and improving physical properties and texture of food. It is used as a stabilizer for ice cream, an adhesive for ketchup, mayonnaise, sauce, etc., a clarifier for rice wine, a gelling agent, an emulsifier, and a thickener.

Formula (C6H7O6Na)n. It is white to pale yellow fibrous, granular, granular or powder, almost odorless and tasteless. It is insoluble in alcohol, insoluble in organic solvents such as chloroform, and slowly soluble in sodium carbonate, sodium hydroxide, and sodium phosphate. It is viscous when dissolved in water and has excellent effects as a stabilizer and thickener. The pH of a 1% aqueous solution is 6-8. If the aqueous solution is kept at a high temperature for a long time, the viscosity may decrease, but there is no change in viscosity below 80 ° C.

In addition, when divalent or higher metal ions such as calcium chloride, barium chloride, aluminum sulfate, zinc sulfate, copper sulfate, silver nitrate, iron (III) chloride, and lead acetate are added to the aqueous solution, it solidifies into a metal salt. However, in the case of water-soluble magnesium salt and mercury salt, it does not coagulate, and in the case of table salt of 8% or more, it coagulates and loses viscosity.

Therefore, when preparing an aqueous solution, it is better to mix it with alcohol or propylene glycol and then add water to dissolve it. When acid is added to an aqueous solution of sodium alginate, alginic acid precipitates and precipitates. It starts to dissolve at pH 5.8 and becomes a viscous liquid. The viscosity varies depending on the concentration, temperature, degree of polymerization, etc. If the degree of polymerization is 75, it is 70cps, if it is 84, it is 140cps, and if it is 130, it is 1,000cps.

The present invention is an edible adhesive containing the agar-agar described above,

Apply the edible adhesive 20 formed in step S120 to the surface of the paper 10

By coating, made to mutually adhere (S130) with other paper (10); edible adhesive characterized in that

If the manufacturing process of step S100 is described in detail,

Add 10 g of sodium alginate to 1 liter of water and mix in a blender.

To prepare a sodium alginate liquid 11 sufficiently mixed with each other. (S100)

In general, since the liquid used in the cooking vessel is within 90 ° C, a manufacturing process such as the step S100 is required to accommodate the hot liquid of about 90 ° C contained in the container.

To this end, water and sodium alginate are mixed at the mixing ratio described above to form a sodium alginate liquid 11 stirred in a mixer for about 10 minutes.

The sufficient mixing process in the mixer is because water and sodium alginate must be sufficiently mixed to be mixed with the material of the next step.

In addition, the next manufacturing step relates to a step (S110) of adding 10 to 15 ml of gelatin to the step S100 and mixing them in a mixer.

The gelatin is responsible for the function of increasing the adhesive force required to bond paper to each other, and if the amount of gelatin is large, it is easily soluble in water when used after preparing an edible adhesive and putting it in a beverage container. , In the case of the above-mentioned quantity, it is responsible for the function of maintaining the shape of the container even if it is contained in the beverage container for about 4 hours.

In addition, as the next manufacturing step, 4 to 8 ml of agar-agar is added to the step S110 and mixed with each other in a mixer (S120).

The agar-agar is responsible for the function of structurally hardening after paper and paper are adhered to each other, and at the same time, if the agar-agar is more than the set amount, the viscosity is insufficient, and it becomes a paste, so it is difficult to spray on the paper surface when spraying .

Quantification of the appropriate amount of gelatin and agar-agar described above is the optimum appropriate dose for edible adhesive.

Here, the gelatin is soluble in water at about 16 ° C, and agar-agar is soluble in water at about 80 ° C.

By the above steps S100 to S120, when the water, gelatin and agar are sufficiently mixed by a mutual mixer, stir well to mix them uniformly until they boil to about 90 ° C. After cooling to room temperature, it is coated on the surface of the paper (20).

As shown in Figure 2, as an embodiment of the present invention,

The edible adhesive 20 prepared in step S120 is coated or sprayed on the surface of the paper 10, then bonded to another paper 10, formed to a certain thickness, and then rolled to produce the required disposable container. .
