Using the packaging materials prepared in the above Comparative Examples and Examples 1 to 4, the freshness of the food was allowed to stand at 63 캜 for one week, and then the acid value and the peroxide value were measured using the stored almonds. The almonds were stored in the packaging materials prepared in Comparative Examples and Examples 1 to 4 and then subjected to an aptitude test in Esfood Guardian Co., Ltd. Based on the amount of reagent consumed according to the following method of measuring the acid value and peroxide value .
The test report was prepared by Esfood Guardian Co., Ltd. The results are shown in the following FIG. 2 to FIG. 6 and are summarized in Table 1 below.
The acid value is one of the measures to determine the quality of the fat, which means the mg of potassium hydroxide (KOH) required to neutralize the free fatty acids contained in 1 g of fat. It is preferable that the acid value of the edible oil is 1 or less.
At peroxide value, the oxidation of the fat begins from the production of peroxide, so the peroxide value, which indicates the amount of peroxide produced, is used as an indicator of the degree of oxidation of the fat. Since the peroxide is reduced by polymerization and decomposition at the same time as it is produced, the amount of peroxide actually measured as the peroxide value is not the total amount of peroxide produced, but the amount excluding the reduced amount due to polymerization and decomposition at the production amount. That is, do. In the early stage of oxidation of peroxides, the rate of peroxide is higher than the rate of decrease, so the peroxide value increases with the oxidation. However, when peroxides are accumulated due to oxidation, the peroxide peroxide value decreases because the rate of peroxide is higher than that of peroxide. Therefore, the peroxide value is high in the initial stage of oxidation of the oil. The principle of measurement of peroxide value is as follows. When potassium iodide (KI) is reacted with the fat, iodine (I) is liberated quantitatively from potassium iodide by peroxide. The iodine titration method, which titrates this with a standard solution of sodium thiosulfate in the presence of a starch indicator, is widely used because of its high reliability. The peroxide value is expressed in milliequivalents (meq / kg) of peroxide oxygen converted from the milliequivalent of iodine liberated per 1 kg of fat. By measuring the amount of peroxide generated by oxidation of the fat, Lt; RTI ID = 0.0 > efficacy. ≪ / RTI >
Referring to the results of Table 1, it can be seen that the acid value in Comparative Example 1 and Examples 1 to 4 is not less than 1, and that the acid value is not possible to be edible, and there is no significant difference in the acid value between Comparative Examples and Examples.
However, when comparing the peroxide value, it was found that the peroxide value was 6.00 in Comparative Example 1, but the peroxide value dropped from 4.00 to 1.00 in the packaging material containing the antioxidant pigment composition according to one aspect of the present invention. That is, when the antioxidant pigment composition of Example 1 contained 6 wt% of the antioxidant pigment composition and the antioxidant pigment composition of Example 2 contained 10 wt% of the antioxidant pigment composition of Example 2, the peroxide value was 4.00 It can be seen that the progress of the rancidity decreased by 33.3%. Compared with the comparative example, when the antioxidant pigment composition of Example 3 contained 15% by weight of the antioxidant pigment composition, the peroxide value fell to 3.00, indicating that the extent of rancidity was reduced by 50.0%. In Example 4 Compared with the comparative example, when the antioxidant pigment composition was contained in 20 wt% of the packaging material, the peroxide value fell to 1.00, indicating that the degree of rancidity was reduced by 83.3%.
Thus, when the antioxidant pigment composition according to one aspect of the present invention is included in the packaging material, it is possible to slow the progress of rancidity of foods and the like in the packaging material, to suppress the oxidation of the food to maintain the freshness of the food, It will increase.
In addition, the packaging material containing the antioxidant pigment composition according to one aspect of the present invention can be used not only as a food but also as a packaging material for steel products, thereby preventing oxidation of steel products and preventing corrosion. In the export of steel products, To increase exports and increase the national competitiveness of the steel industry.
The present invention also relates to an antioxidant pigment composition or a shungite of the present invention. The antioxidant pigment composition of the present invention can be used in various fields such as packaging for preventing oxidization in addition to foods and steel products, and packaging materials for flower, mulching for agricultural use, Is not limited to a film such as a vinyl film, but may be used in addition to plastic compositions and pulp (or paper).
