PROBLEM TO BE SOLVED: To measure a composition ratio of a methane gas and a carbon dioxide gas for mainly composing a biogas by a weight method. SOLUTION: The methane gas and the carbon dioxide gas within the gas to be measured are separated and collected, and a weight ratio of the collected methane gas and carbon dioxide gas is derived as the composition ratio by sequentially implementing the first dehydration process for removing water from the gas to be measured as the biogas, the first carbon dioxide gas collection process for converting the carbon dioxide gas within the gas to be measured into carbonate and water, and collecting it, the methane gas burnup process for burning the methane gas within the gas to be measured, and converting it into the carbon dioxide gas and water, the second dehydration process for removing water from the gas to be measured, and the second carbon dioxide gas collection process for converting the carbon dioxide gas within the gas to be measured into carbonate and water, and collecting it.

PROBLEM TO BE SOLVED: To provide a method for industrially and efficiently producing highly pure astaxanthin without affecting a production amount of chitin in a process for producing chitin from shells of crabs and shrimps.SOLUTION: In the process for producing chitin from shells of crabs and shrimps, after removing calcium by hydrochloric acid soaking performed therein, ethanol is added to the shells of crabs and shrimps washed with water without carrying out neutralization so that a final concentration of ethanol becomes not higher than 70%. Astaxanthin is extracted by soaking the shells of crabs and shrimps in the solution for several hours while heating the solution. An extract and the shells of crabs and shrimps are separated from each other, and the shells of crabs and shrimps are returned to the process for producing chitin. After a deproteinization process of soaking in a sodium hydroxide solution, chitin is produced. When ethanol is removed by reduced pressure treatment after adding edible oil to the extract containing astaxanthin, astaxanthin is dissolved and spread in the edible oil, and then, an edible oil layer is collected to obtain an astaxanthin-containing oil.

PROBLEM TO BE SOLVED: To provide a nutrition supplement food (vitamin supplement food) using all of the raw materials originating from foods without using chemically synthesized vitamin raw materials originating from petroleum. SOLUTION: This nutrition supplement food is produced by using a vitamin B group-enriching yeast (RDA yeast) instead of the chemically synthesized vitamin raw materials originating from the petroleum. Thereby, it becomes possible to supply the vitamin B group completely without using any of the synthesized raw materials originating from the petroleum, and the nutrition supplement food the all of the raw materials of which are originating from the food, meeting to the needs of general consumers is provided.

PROBLEM TO BE SOLVED: To solve such problems that although Sake lees vinegar is known to contain rich amino acids and organic acids more than those of general cereal vinegar or rice dark vinegar according to recent researches, it is not easy to obtain the Sake lees vinegar by a consumer, also since the Sake lees vinegar has a peculiar dark color and a strong smell, it is difficult to prompt the use of the Sake lees vinegar as a food for the consumer, etc.SOLUTION: This health food is provided by containing a powdery material or an extract of the Sake lees vinegar, prepared as a solid state or a semi-solid state and preferably prepared by mixing with a material obtained by adding calcium to a fermented vinegar such as rice dark vinegar and filtering. By the addition, it is possible to add the calcium having an effect for osteoporosis even as a powdery state while sufficiently securing an acetic acid content. Since the Sake lees vinegar is made as the preparation, it can be carried out and can be ingested orally always and anywhere.

PROBLEM TO BE SOLVED: To provide a quantitative measuring instrument of a gas capable of appropriately corresponding to an animal from an extremely small experimental animal to a relatively large experimental animal even if the detection capacity of a detection part is raised in spite of a compact and simple constitution. SOLUTION: The quantitative measuring instrument of the gas is equipped with a gas flowing route 3 for guiding the gas from its one end to discharge it to its other end, a closed housing container 5, the detection part 27 for allowing the gas, which is discharged from the housing container 5 to flow in to detect the same, a bypass route 39 for guiding the gas so as to bypass the detection part 27, the solenoid valve 41 for connecting the gas flowing route (detection route 38) passed through the detection part 27 and the bypass route 39 in a changeable manner and a controller 45 for controlling the solenoid valve 41 at a predetermined time interval. An H 2 SO 4 solution is put in an ammonia absorbing bin 29 so that the flow rates of the gas become same even if the gas is passed through all of the routes and air passing resistance is adjusted by the surface height of the H 2 SO 4 solution to limit the flow rate of the gas.
