Description

Paper wrapping paper for food packaging with excellent odor and antibacterial performance

The present invention relates to paper wrapping paper for food packaging having excellent odor and antibacterial performance.

Various types of food wrapping paper are used for food packaging. In order to improve dual moisture resistance, wrapping paper coated with petroleum-based paraffin wax at a constant thickness on a base such as paper or non-woven fabric is mainly used.

For example, in Korean Patent Registration No. 10-1060367, a wrapping paper formed by applying a composition obtained by mixing paraffin wax and polyethylene and adding a certain amount of colloidal platinum to the base, wherein the contents of the paraffin wax, polyethylene and colloidal platinum are paraffin wax 80 to 89% by weight, 10 to 20% by weight of polyethylene, and 0.01 to 5% by weight of colloidal platinum, a food wrapping paper is disclosed.

However, when the wrapping paper coated with paraffin wax is used in a relatively high-temperature environment, the wax melts and flows down, which causes a problem in that the taste of the wrapped food is deteriorated, and there is a problem that is harmful to the human body.

In recent years, attempts have been made to utilize kraft paper itself, which is not separately processed, as a wrapping paper for bread, donuts, fries, and the like.

On the other hand, when kraft paper is used as a wrapping paper for food, when the food is wrapped over a certain period of time, various bacteria such as staphylococcus, salmonella, vibrio, and E. coli propagate on the food wrapping paper, resulting in food spoilage However, there is a problem that promotes or is harmful to the human body, and a solution to this problem is required.

Experimental Example 1: Evaluation of antibacterial performance

10 mL of the odor-antibacterial composition of Example 1 was put into an Erlenmeyer flask, and heat-treated at about 120 ° C. for 15 to 20 minutes to sterilize.

Subsequently, 90 mL of physiological heart water (8.5% NaCl aqueous solution) and 1 mL of the cultured test strain were added to the composition, mixed, and shaken for about 24 hours at about 35 ~ 39 ℃ and 31.5 ~ 31.9% R.H conditions. After culturing, a certain amount was collected and spread on an agar medium to measure the number of bacteria.

Subsequently, the bacterial reduction rate was calculated using the initial bacterial count (1.7Х10 ⁴ ) and the measured bacterial count, and is shown in Table 7 [Unit: %]. The results of the applied case are also shown together.

At this time, the super bacterium MRSA (Staphylococcus aureus subsp, aureus ATCC 33591) was used as the test strain, and the test strain was cultured in Nutrient liquid medium.

In addition, the antibacterial performance was evaluated using the compositions of Examples 2 to 4 and Comparative Examples 1 to 19 in the same manner as above, and the results are shown together.

Looking at Table 7, it can be seen that the antibacterial effect of the odor-antibacterial composition according to the present embodiment is excellent.

On the other hand, in Table 7, in the case of the control group, as the number of bacteria increased after 24 hours from the initial period, the bacterial reduction rate was evaluated as negative.

Experimental Example 2: Flavor performance evaluation

After diluting the odor-antibacterial composition of Example 1 in water about 15 times, it was applied to one side of Korean paper, cured, and dust and non-adherents were removed by shaking the dried Korean paper. After this, to a group of 10 fragrance evaluation expert panels,

i) immediately after the composition has been applied and cured; and

ii) after repeatedly shaking off the Korean paper coated with the composition about 30 times and leaving it for about 1 month;

At this time, the fragrance intensity was evaluated by a 1 to 5 point method, and the closer to 5 points, the stronger the fragrance intensity.

In addition, fragrance performance was evaluated using the compositions of Examples 2 to 4 and Comparative Examples 1 to 19 in the same manner as described above, and the results are shown together.

Looking at Table 8, it can be seen that the fragrance-antibacterial composition according to the present embodiment had excellent fragrance. In particular, in the case of this embodiment, it can be seen that the persistence of the fragrance is excellent.

On the other hand, in Comparative Examples 4, 7, 8, 9, 10, and 11 to 19, in the case of ii), it can be confirmed that the fragrance strength is weak, which means that the fragrance-antibacterial composition is applied to Korean paper, cured, and then dried. In the process of shaking and removing dust and non-adherents, it is determined that some components are removed due to the deterioration in the dispersibility of each component and the adhesion of the coating layer, resulting in a decrease in fragrance strength overall.

Experimental Example 3: Evaluation of Adhesion of Fragrance-Antibacterial Composition

Adherence of the odor-antibacterial compositions of Examples and Comparative Examples was evaluated, and the results are shown in Table 9.

Specifically, the adhesion evaluation is performed by a cross-cut test, and after evaluating the results according to ASTM D 3359 classification criteria, the average values of 10 times are shown in Table 9.

adhesiveness adhesiveness Example 1 4.5B Comparative Example 9 2.0B Example 2 5.0B Comparative Example 10 3.0B Example 3 5.0B Comparative Example 11 2.0B Example 4 4.5B Comparative Example 12 3.0B Comparative Example 1 5.0B Comparative Example 13 3.0B Comparative Example 2 2.0B Comparative Example 14 3.0B Comparative Example 3 5.0B Comparative Example 15 3.0B Comparative Example 4 2.0B Comparative Example 16 3.0B Comparative Example 5 5.0B Comparative Example 17 3.0B Comparative Example 6 2.0B Comparative Example 18 3.0B Comparative Example 7 2.0B Comparative Example 19 3.0B Comparative Example 8 3.0B

Looking at Table 9, it can be seen that the odor-antibacterial composition according to the present embodiment has excellent adhesion.

That is, taking the above contents together, the odor-antibacterial composition according to the present embodiment implements excellent antibacterial performance, odor performance and adhesion, and the paper wrapper of the present embodiment including the same has excellent odor and antibacterial performance and durability thereof. can do.

[Production Example]

A base layer formed of kraft paper having a thickness of 2 mm; and

Paper wrapping paper for food packaging was prepared by applying and curing the odor-antibacterial composition of Example 2 on one surface of the base layer to form a film-like odor-antibacterial layer.

As described above, the description of the present invention is for illustrative purposes, and those skilled in the art to which the present invention pertains can easily be modified into other specific forms without changing the technical spirit or essential features of the present invention. You will understand. Therefore, the embodiments described above are illustrative in all respects, and should be understood as non-limiting. For example, each component described as a single type may be implemented in a distributed manner, and similarly, components described as distributed may be implemented in a combined form.

The scope of the present invention is indicated by the following claims rather than the detailed description above, and all changes or modifications derived from the meaning and scope of the claims and equivalent concepts should be construed as being included in the scope of the present invention. do.
