Traditional methods to process mackerels are as follows: preserved with salt after internal organs are removed, vacuum packed after edible parts are cut and matured, or frozen after the head and internal organs are removed. Here, we have stood by the traditional processing methods, and conducted intensive research on the processing methods of mackerels to develop new croquette-line products for patenting. Our R&D Department is operated under the certification of the government, and is continuously ongoing research on various products using mackerels. In particular, we are striving to develop various processed foods by adding appropriate spices to filets for easy cooking at home. We will make a ceaseless effort to suit diverse tastes of our customers.
