Recently, with the increase of the general living standards of the people due to the increase in income, there is an increasing demand for healthy functional foods with excellent nutrition and quality in diet. In addition, due to the objection to artificial pigments, research on materials to replace them is being actively conducted from natural products. Therefore, many processed foods that increase the nutrition and quality of foods by adding natural additives to existing foods are being released. There are also many well-being foods that transform existing foods with social attention to well-being.

Ice cream is an American-style food developed primarily in the United States, first produced in the United States in the 1800's since it was first frozen in southern Europe in the 15th century. Ice cream is made by mixing fat, sweeteners, emulsifiers, stabilizers, flavors, pigments, and water with the main ingredient milk to soften the tissue. As the flavor and color added to the ice cream, vanilla, chocolate, strawberry, pineapple, and the like are mainly used, and ice cream using various additives such as walnuts and pine nuts is commercially available. Recently, the consumption of ice cream is rapidly increasing, and the flavor and pigment added to the ice cream are becoming important factors that determine the quality and sensuality of the product according to the diversification and luxuryization of products.

Noodles are made from cereals or starches, and are a highly preferred food for modern people seeking to simplify their diet. Noodles include dried noodles, deep-fried noodles, improved noodles and frozen noodles, and dried noodles are dried raw noodles or deep-fried noodles made from cereal or starch. Looking at the size of the domestic cotton market, it is reported that dry noodles account for about half of the total market. Therefore, the expansion of consumption due to the diversification of dry noodles will increase the utilization of domestic wheat in the consumption market and develop high value-added products.

Tofu is a highly nutritious food that fills the essential amino acid content that is often lacking in grain-based diets. Tofu is not only effective for preventing adult diseases such as arteriosclerosis, heart disease and cancer, but also has a high digestive absorption rate. However, tofu is soybean is the main raw material, so the nutrition of soybeans has little other nutritional facts. Therefore, research is needed to improve the taste and aroma of tofu by adding other substances to tofu.

Although bread is not a traditional Korean food, consumption is rapidly increasing due to the demand for convenience and satisfaction due to westernized eating habits. Bread is widely used as a snack and stock, especially among young people. As a concept of health food, research on functional bread using various additives is being actively conducted, and it is already on the market and is gaining popularity.

The ocean, which accounts for about 70% of the earth's surface, is a treasure trove of resources. Algae among marine organisms are rich in minerals and vitamins, and have a distinctly soft taste and aroma. Seaweed is a type of seaweed that is well digested, contains high quality protein, and is rich in vitamins and minerals. It contains eicosapentaenoic acid (EPA), which prevents blood clots that cause stroke and heart disease, and a substance that prevents cancer. Vitamins contained in seaweed are excellent in terms of type and quantity. In particular, cyanocobalamin (vitamin B ₁₂ ) has growth and hematopoiesis, which is effective for children's growth and women's anemia. In addition, it is known as a low-calorie food with excellent taste and nutrition because it is delicious and easy to enjoy. Therefore, it is expected to be used as a suitable natural product that can solve the health-oriented aspects of consumers and the rejection of artificial colors.
