Salted seafood is a traditional Korean fermented fish food that suppresses the growth of decayed bacteria by salting fish and shellfish and decomposes meat by the enzyme action of autodigestive enzyme or microorganism. The product has a unique rich flavor and is widely used as a seasoning material for side dishes and kimchi from ancient times to today (preservation effect of low salted salted cod roe with Kim Sang-mu, food additives, Korean Journal of Food Science and Nutrition, 25 (6) , pp.937-943, 1996).

The fermented seaweed is fermented by fermenting only raw salt of salt, which is not subjected to heat sterilization treatment, as a needle source. It is a process of decomposing the nutrients by the proteolytic enzymatic action of self-digesting enzymes and rheological microorganisms, the unpleasant smell of such take wonryoyuk destroyed and desirable flavor components are generated, and the meat is softened to be differentiated in a state suitable for human consumption (Kim YM. 1996. Processing technique and quality control of seafood fermented (in Korea). Bulletin of Food Technology , 9: 65-86).

In recent years, as consumption of health-oriented foods has increased, the fermented product has been widely used in the form of seasoned salted fish which has a much lower salt content. However, such seasoned salted salted fish is one of the biggest problems It is shortening of storage stability of salted fish. The addition of antioxidants may be considered to extend the storage period of the fermented seafood, but it is difficult to put the antioxidant into practical use due to the expectation of consumers and the avoidance of artificial synthetic additives. For this reason, it is widely known to prevent oxidation of oils and fats by blocking the oxygen in the air and light, which causes rancidity and decay of salted fish, by physical methods other than antioxidants. This extends.

In this experiment, we tried to suppress the rancidity of salted fish while prolonging the storage period by making them in a vacuum while packing them in a light and oxygen barrier container.

As a vacuum container, a retort pouch refers to a container for heat-resistant food packaging that can be sterilized by a high pressure sterilizer or other sterilizing device to maintain commercial sterilization. A flexible pouch which is filled with food and then sealed and sterilized by heating at 100 to 140 캜. Typical examples of the material are a polyester in the surface layer, an aluminum foil in which the gas and water do not permeate in the middle layer, Is made of polyolefin or the like having good heat sealability and good contact property with food. The characteristics are thinner than the metal tube, and the quality is improved because the time taken for the center temperature of the contents to reach the target temperature is short. Like canned food, it can be distributed at room temperature, can be stored for a long time, has a small container storage space, is light in weight, and is also called a retort pouch. The retort pouch uses a lamination film, which is made by attaching three layers or five layers of plastic film or aluminum foil with different properties to improve heat resistance, gas permeability and heat adhesion. The laminated pouches for retort pouches are mainly made by laminating three layers of polyester (0.0122mm) / aluminum foil (0.0089mm) / modified polypropylene (0.176mm), but using aluminum retort pouch. Examples of lamination are polyester / polyurethane / adhesive / modified polyester / modified high density polyethylene. Retort pouches are lighter and easier to carry, easier to cook, less heat-treated, and have a higher quality than retort pouches, but have a slower production rate, difficulty in distinguishing easily the altered tubes, and the possibility of contamination by pinholes (Naver Encyclopedia; www.naver.com)

Accordingly, the present inventors can improve the shelf life of salted fish and suppress the growth of the causative agent of spoiled salted fish during storage of fermented salted fish, and the quality and shelf life of microorganism, pH, VBN and TBA are superior to that of commercially available salted fish. By reducing the amount of returned and discarded due to deterioration to prevent the waste of food resources, to reduce the production cost of the product, there is an advantage in improving the quality of the product has been completed in the present invention a method of storage of seasoned roe using retort pouch film.

In accordance with the above object, the present invention provides a packaging method for storing the fermented roe with excellent quality and shelf life using a retort pouch film.

During storage, the total number of microorganisms in the fermented kochujang was 3M Aerobic Count Plate film (55144-1000) and the number of lactobacillus was added to BCP-added agar medium (DIFCO (E-MB31)).

As a result of the experiment, the change of the total bacteria according to the maturation period of the different seasoning changran chopped as shown in Table 1. There was no significant difference between the samples until the 3rd day of storage, but the total number of germs of PET + Al + PP packaged egg showed the highest number, and PET + Al + PP + vacuum and PET + Al + PP nitrogen packaged egg added from the 6th day of storage. Although the number of bacteria was the smallest, there was no significant difference between the two samples.

It was measured as follows using a pH meter while storing for 3, 6, 9, 12 days at 25 (± 5) ℃ for the changranjang prepared in the above Example.

The pH was measured using a pH meter (Mettler Toledo, SevenEasy pH, switzerland) after homogenizing by adding 10 mL of sample to 20 mL of distilled water.

As a result of the experiment, the pH change according to the ripening period of the high-quality Changlan chops with different packaging is shown in Table 2. The initial pH of the cod roe was 6.03, which did not show any significant difference among the different packing methods. The pH decreased until 6 days of storage and then increased from 9 days. This means that all samples began to rot from day 9, and the pH change was the largest in PET + Al + PP + vacuum-packed languid and the smallest in PET + Al + PP-packed languid.

Antioxidant activity was measured as follows while storing for 3, 6, 9, and 12 days at 25 (± 5) ℃ for the fermented kochujang prepared in Example 1.

Twenty grams of ground cod roe was taken, and 50 mL of 20% Trichloroacetic acid in 2M phosphoric acid solution containing 2M phosphoric acid cooled to 4 ° C was homogeneously ground for 1.5 minutes, and then the grinding solution was used as a 100 mL flask. . The solution was filtered through a Whatman No. 1 filter paper and centrifuged at 15000 ppm for 10 minutes using a centrifuge (micro centrifuge; Mega 21R). After filtration, 5 mL of the supernatant was transferred to a test tube and treated with 0.005 M 2- And 5 mL of TBA (thiobarbituric acid). The color developed liquid was measured at 530 nm absorbance (Jasco, JP / V-550), and the measured absorbance was multiplied by 5.2.
