Paste can be made by fermenting fish or shrimp for a long period of time or salting the fish after pounding it hard.
Sikhae is rather a modified version of Jeot. It is made by mixing ingredients such as fish, rice or millet, salt, etc. Its origin is closely related to the distribution of rice. The origin of rice is located in the triangle area of the Ganges River in India. The area is rich with both seawater and freshwater fish, yet with less sunlight. Malt, which is used exclusively in Korea for preservation, is an important ingredient to produce gazami shikhae, made with halibut. Myanmar, Thailand, Laos, etc., which are located far from the ocean, lack salt and do not make salted fish. Since drying fish is not an option during a dry season, the countries have developed a way of preserving fish by adding salt and steamed rice to them, which creates lactic acid and prevents decomposition. This is the original form of sikhae. It disappeared from China after the 18th century.12 In Korea, in order to make sikhae, especially halibut sikhae, malt and chili powder are used. However, in Japan, the two ingredients are not necessary to make narezushi13(matured sushi, especially mackerel narezushi with a long fermentation period is called hon-nare, and one with a shorter period is called haya-nare). Today, sikhae barely survives in Korea while nigiri sushi becomes popular in Japan. There is also funazushi made from carp in Japan. It is less popular with people due to its pungent odor.
5. Context-Setting in the Development of Contents
It is essential to select appropriate methods in order to promote studying effect when fermented fish food products are provided for educational contents. For example, it is likely to be better to demonstrate a whole process by classifying the contents according to a certain period of time living up to learners, rather than to list fragments of information. To achieve this, it is crucial to rearrange every factor that affects on the contents and connect them logically.
In general, producing contents comprises of three steps such as pre-production, main-production, and post-production. If precise and accurate standard is not properly established in the course of pre-production, the later steps will not guarantee good quality. Particularly, Digital contents like websites and computer software require simple and accurate architecture to reduce errors and speed up operation of programs.
