Associate Professor Kazuhiro Shiozaki My name is Kazuhiro Shiozaki, associate professor of Field of Fisheries Food Sciences, Faculty of Fisheries. In our field, “Food Technology” is one of the attractive majors and is quite important to transform fish into more delicious forms for food and other forms for biofunctionallity. Around Kagoshima Prefecture, plenty of “delicious fish” are present and many people in fisheries industry are making efforts to prepare them as food for consumers. On the other hand, “non delicious fish” are also available and are not considered as useful part of the fish resources. Therefore, finding new ways of utilizing these fish is a significant task for the development of fisheries industry. Here, I briefly talk about my research on the usage of dwarf gulper shark, “non delicious fish”.
Dwarf gulper shark is a deep-sea shark living in tropical to temperate marine waters and also in Amami lslands (Kagoshima Pref.). This shark is known to possess a large amount of squalene in the liver. As squalane is a useful substance for human health, squalene is extracted from dwarf gulper shark and industrially converted to squalane with hydrogen addition. On the other hand, the consumption of its meat is quite limited because high amount of ammonia gradually builds up as the freshness decrease. |
