Description

Method of manufacturing bioplastic using hoesaengi cap and mandarin peel and bioplastic manufactured by the manufacturing method {METHOD OF MANUFACTURING BIO PLASTIC AND BIO PLASTIC MANUFACTURED THEREBY}

The present invention relates to a method for manufacturing a bioplastic using hoesaeng hat half and tangerine peel, and a bioplastic manufactured by the manufacturing method, and more particularly, extracting pectin and agar from hoesaeng mackerel and extracting starch from tangerine peel, , It relates to a method for manufacturing bioplastics using hoesaeng hat half and mandarin orange peel, which enables manufacturing of biodegradable bioplastics by mixing and molding pectin, agar, and starch, and bioplastics manufactured by the manufacturing method.

As the production and usage of plastics increase, technologies for developing and commercializing bioplastics using various recycled materials are being disclosed.

For example, bowls commercialized using water, potato peel starch, cellulose, and wax are being developed.

However, in this method, starch is obtained from potato skins, while cellulose is purchased from external sources to make bioplastic bowls. Conversely, if, for example, empty fruit clusters of oil palms are used as cellulose, starch is also required, so bioplastics are made by importing already made starch.

If cellulose is extracted, use starch. If starch is extracted, cellulose must be used.

On the other hand, on the coast of the southern seas of Korea, including Jeju Island, large-scale seaweeds frequently occupy not only the sandy beaches but also the stones. Even the giant algae in the way the waves come in can block the waves from entering the sandy beach.

Among them, hoesaengi mother-and-child group, which grows a lot on the beaches of Jeju Island, covers the beach, and in some cases, the government and local governments have to use a garbage collection tong truck to lift and collect the hoesaengi mother and child.

The hoesaengi mother and child are attached to the nets of fishing grounds and farms to damage the fishing grounds, or are distributed along the coast to damage the beaches and stink, pollute the natural landscape. The development of a method for effectively removing such hoesaeng hat spots is required.

The hoesaeng mother and child groups collected by the government are distributed to farmers who have applied for fertilizer. The budget and manpower required to transport the hoesaeng mother and child half to the farmhouse is huge, and the time required in the fertilizer manufacturing process, odor generation, Farmers are reluctant to use fertilizer because of the salt remaining in the soil. Also, in 2015, Jeju-do conducted a demonstration project for fertilizing seaweed using useful microorganisms, but it was canceled due to cost and effectiveness.

As described above, there is an urgent need to develop a technology for collecting and removing the mother-and-bearing ferrets covering the coast of Jeju Island and the southern coast and converting them into useful resources.

As shown in FIG. 1 , the method for producing bioplastics using the "method for producing bioplastics using hoesaeng hat half and orange peel" of the present invention includes the steps of extracting pectin from hoesaeng hat half (S102), hoe It includes the step of extracting agar from raw mother and child (S104), and extracting the starch from the orange peel (S106). The bioplastic is manufactured through the steps of preparing a resin chip by mixing the pectin, agar, and starch thus extracted (S108), and molding the bioplastic resin chip made in this way (S110).

As shown in FIG. 2, in order to extract pectin from hoesaeng mother and child, first, hoesaeng mother and child that have been pushed to the beach are collected. (S202)

The collected hoesaengi caps are washed to remove foreign substances and salt, dried naturally to remove moisture, and pulverized into small pieces to facilitate extraction. (S204)

Hydrochloric acid (HCl), which is an acidic solution, is added to the hoesaeng hatban that has been crushed into pieces. (S206)

And, the extraction of pectin is accelerated by heating the hoesaeng hat half to which hydrochloric acid is added. (S208) The heating process can be performed by boiling at a temperature of 60°C to 70°C for 2 hours or heating in a microwave for about 15 minutes. have.

A 0.5% concentration of ammonium oxalate solution is added to the treated hoesaeng hat, and heated at a temperature of 40°C to 60°C for about 30 minutes to 60 minutes. (S210)

Ammonium oxalate has a chemical formula of "(NH ₄ ) ₂ C ₂ O ₄ ", and monohydrate is determined in aqueous solution by the action of aqueous ammonia and oxalic acid. If the monohydrate is dehydrated at 65°C, anhydrous salt is obtained.

And filter the crystal component with a suction filter (Buchner funnel). (S212)

Then, alcohol is added to cause precipitation. (S214) Preferably, ethanol is used as the alcohol.

Finally, the precipitated pectin is separated. (S216)

On the other hand, as shown in Figure 3, it is possible to extract agar from hoesaengi hat half.

First, as shown in FIG. 3, first, the hoesaengi mother and child that have been pushed to the beach are collected. (S302)

The collected hoesaeng mother and child are washed to remove foreign substances and salt, dried naturally to remove moisture, and pulverized into small pieces for easy extraction. (S304) Collection, washing, grinding, etc. The process is the same as the process for pectin extraction.

Then, sodium hydroxide (NaOH), which is a basic solution, is added to the hoesaeng hat half pulverized into pieces. (S306)

Then, it is extracted while heating at a temperature of 90°C to 110°C for about 2 hours. (S308)

Then, foreign substances are removed through the filtration process (S310).

Finally, foreign substances are removed and the remaining agar is separated. (S312)

Meanwhile, as shown in FIG. 4 , starch may be extracted from the tangerine peel.

First, the tangerine peels are collected, washed, dried, and pulverized to obtain pulverized tangerine peels (S402, S404).

Sodium metabisulfite solution is added to the sliced orange peel. (S406) Sodium metabisulfite is represented by the chemical formula "Na ₂ S ₂ O ₅ ", and has a white crystal or crystalline powder form. Sodium metabisulfite is an additive used to change general pigments and chromogenic substances into colorless compounds during food processing and to suppress changes in browning and coloration that occur during food preservation. It is used as a preservative, antioxidant, and reduced bleaching agent. do.

Then, it is dried while heating in an oven at a temperature of 140°C to 170°C. (S408) It is preferable to dry until the tangerine peel becomes hard and can be crushed.

Then, the shredded orange peel is pulverized into fine particles to make powder. (S410)

Through this process, pectin, agar, and starch can be extracted. Finally, a resin chip is made by mixing pectin, agar, and starch in an appropriate mixing ratio, and the resin chip is put into a molding machine to make a product in the shape desired by the user.

Through this process, biodegradable bioplastics can be manufactured.
