摘要:
A method and apparatus for measuring the particle diameter of foam on a malt alcoholic drink, which can detennine the quality of the foam of the malt alcoholic drink objectively, are provided. The apparatus for measuring the particle diameter of foam on a malt alcoholic drink according to the present invention includes a laser light source for irradiating a linear laser beam onto the surface of a foam layer created on a malt alcoholic drink, an imaging device for imaging a laser line reflected on the surface of the foam layer to obtain an image of the laser line, and a calculating device for obtaining edge information of the laser line from the image of the laser line to calculate the particle diameter of foam in the foam layer based on the edge information.
摘要:
The present invention relates to a process for producing compost, characterized in that when the compost is produced by inoculating aerobic composting seed bacteria to an organic waste material, the process comprises: supplying oxygen while the waste material is stirred, and supplying water so that the water content of the waste material is 60±5%, and to a process for producing compost, characterized in that when the compost is produced by inoculating aerobic composting seed bacteria to an organic waste material, the process comprises, after begining of the fermentation, adding sugars to the waste material in a divisional manner before a main fermentation is transferred to the amine/ammonium metabolic system. Further, according to the present invention, an apparatus for producing compost is provided. The apparatus comprises: a fermentation vessel having an oxygen supplying means, a water distributing means, and a stirring means; and a control means for detecting or determining the moisture content of an organic waste material contained in the fermentation vessel to control, on the basis of the detected or determined result, the amount of water to be distributed by the water distributing means. According to the present invention, when organic waste materials disposed from food processing factories and the like is processed to produce compost of high quality, formation of ammonium and amines mainly causing unpleasant odors or generation of lower fatty acid which is a factor for a growth inhibition of plants can be suppressed, and the compost can be produced in stable, and within a short period of time.
摘要:
A sugar ester derivative of the general formula (I) ##STR1## wherein G stands for a group of the formula (A) ##STR2## or a group of the formula (B) ##STR3## wherein .lambda. means 0 or 1; at least one of R.sub.1 and R.sub.2 means an ester residue of a saturated or unsaturated fatty acid having 1-30 carbon atoms and the other group means hydrogen atom or acetyl group, and R.sub.3 means a group of the formula (C) ##STR4## wherein X means a halogen atom, m means an integer of 0 to 4, Y means hydroxy group, an alkoxy group, a carboxyl group or sulfonic acid group, n means 0 or 1 and Z means nitro group or nitrovinyl group and its use.The sugar ester derivative of the general formula (I) is useful as a substrate for the measurement of lipase or esterase activities, and the reagents and the methods for measuring lipase or esterase activities which comprise said sugar ester derivative as the substrate are excellent in terms of reproducibility and sensitivity and enable the measurement of lipase or esterase activities in accordance with rate-assay method by an easy procedure.
