Patent number: 8722104Abstract: To an organic substance having a double bond such as a polyunsaturated fatty acid was added an antioxidative component containing an antioxidative sesame component and ascorbic acid or an ascorbyl fatty acid ester. The above method provides a composition containing an organic substance having a double bond exhibiting enhanced oxidative stability. Particularly, it extremely improves oxidative stability of fat and oil which contains polyunsaturated fatty acid. General-purpose refined fish oil which is easy to handle can be provided for food, medicine or feed uses.Type: GrantFiled: November 21, 2003Date of Patent: May 13, 2014Assignee: Nippon Suisan Kaisha, Ltd.Inventors: Nobushige Doisaki, Tsuyoshi Koriyama, Jun Okano, Shuji Jinno

Publication number: 20070275138Abstract: [Problems] To provide a method for controlling hydrogen sulfide odor generating in a treatment of a protein material at a high temperature under elevated pressure. Particularly, to provide a method for controlling hydrogen sulfide odor generating in the production of a food material having a fibrous texture by a treatment with an extruder at a high temperature under elevated pressure. Also, to provide a food material having controlled hydrogen sulfide odor which is obtained by treating a protein material at a high temperature under elevated pressure. [Means for Solving Problems] In the production of a food material obtainable by treating a protein material at a high temperature under elevated pressure, hydrogen sulfide odor is controlled by adding an ascorbic acid analog, preferably ascorbic acid, isoascorbic acid, dihydroascorbic acid or a salt thereof.Type: ApplicationFiled: October 14, 2004Publication date: November 29, 2007Inventors: Takashi Mori, Tsuyoshi Koriyama

Publication number: 20070243309Abstract: To provide minced and heated fish meat material having a texture like meat of livestock, and foods utilizing the material. Fish meat, preferably fish meat wherein the decomposition of trimethylamine N-oxide is inhibited and the denaturation of protein is reduced, is chopped while keeping a frozen state, is heated until denaturation and coagulation of protein while keeping a frozen state and followed by seasoning. Alternatively, the seasoning is carried out simultaneously with the heating. According to the procedure, minced and heated fish meat material having a texture like meat of livestock, can be obtained. The material can be provided as it is, or can be provided as an ingredient of food produced from minced meat of livestock.Type: ApplicationFiled: May 30, 2005Publication date: October 18, 2007Inventors: Toru Mizuguchi, Kenji Ono, Futoshi Samejima, Tsuyoshi Koriyama, Kouichi Yoshii, Takahiro Mikuriya

Patent number: 7018669Abstract: A green soybean having a deep green color, prevented from discoloring, and being adaptable for chilled distribution is provided as a cooked and frozen product. The green soybean is hard to discolor and is frozen after cooking. The green color is retained even in a condition exposed to illumination of light. The green soybean contains chlorophyll a of not less than 3.8 g/100 g wet weight. A material for suppressing decomposition of chlorophyll, preferably an anti-oxidation material, e.g., ?-carotene, is accumulated in tissues of the green soybean. Preferably, ?-carotene of not less than 750 ?g/100 g wet weight is accumulated in the green soybean. The invention also provides a green soybean thawed from the frozen green soybean. The thawed green soybean is adaptable for chilled distribution.Type: GrantFiled: August 6, 2003Date of Patent: March 28, 2006Assignee: Nippon Suisan Kaisha, Ltd.Inventors: Masahito Kosaka, Tsuyoshi Koriyama

Publication number: 20040142088Abstract: Frozen vegetables capable of keeping good texture after freezing and then thawing. Vegetables in which peroxidase has been inactivated or its activity is lowered by superheated steam. Vegetables in which peroxidase has been inactivated and which have been sterilized. Cooked vegetable foods suffering from less worsening in texture, which have been sterilized and in which peroxidase has been inactivated by a cooking treatment with the use of superheated steam. Cooked vegetable foods wherein the above-described worsening in texture is attributable to softening of the texture, enhanced water release caused by separation and flowing out of water in chewing, and change into the porous and sponge-like form after freezing and then thawing. Frozen products of the vegetables or the vegetable foods described above, or thawed products thereof which are adaptable for distribution in a chilled state.Type: ApplicationFiled: March 5, 2004Publication date: July 22, 2004Inventors: Masahito Kosaka, Tsuyoshi Koriyama

Patent number: 6716463Abstract: A coming layer agent is provided which can substantially avoid water from transferring from a food substrate to a “coatings”, such as a sheet and a coating, even when the food has been freeze-preserved, and which can prevent a decrease in crispness of the “coatings” after the food has been cooked by a microwave oven. A coating layer agent composition for frozen foods to be microwave-heated, each of the foods comprising a food substrate and a “coatings”, is featured in containing an emulsifier, preferably acetylated monoglycerides and/or protein, and/or oil and fat. The composition can be used in the form of powder mixed with and adhered to silicon dioxide. In this case, the composition can contain a coating layer agent preferably in the range of 100-250 weight % for silicon dioxide, and also can contain thermo-coagulating protein.Type: GrantFiled: July 31, 2000Date of Patent: April 6, 2004Assignee: Nippon Suisan Kaisha, LtdInventors: Tsuyoshi Koriyama, Satoshi Nakamura
