摘要:
The present invention provides an agent for improving taste of tea drinks, comprising at least one glyceroglycolipid, preferably monogalactosyl diacylglycerol or digalactosyl diacylglycerol, as an active ingredient. The agent of the present invention is for use to enhance kokumi, to mask astringent taste, and to prevent precipitates. The agent of the present invention is effective especially in improving tea drinks containing ground tea leaves. The present invention also provides a method for producing tea drinks containing ground tea leaves and at least 1.0 μg/ml of glyceroglycolipids and having an absorbency of 0.25 or below at 680 nm, and tea drinks containing glyceroglycolipid, which method comprises grinding tea leaves into an average particle size of 1-100 μm (preferably 1-50 μm, more preferably 1-20 μm), and mixing the resulting ground tea leaves with neutral (pH 5-7, preferably 5.5-7, especially preferably 6-7) water to elute the glyceroglycolipids into the water.

A roasted plant extraction apparatus is provided which is capable of selectively reducing excessive bitterness in an extract liquid obtained by water extraction from a roasted plant raw material while preserving desirable flavor ingredients and body. A beverage extraction apparatus includes a granule containing part containing granules for extraction of a beverage, first pouring device for pouring an extraction solvent into the granule containing part from a first direction, and collecting device for collecting a coffee extract liquid extracted by device of the extraction solvent at the side of layers of the coffee granules corresponding to the first direction. The granule containing part is provided with a detachable restraining member for placing the granules for extraction of a beverage in a substantially sealed state.

To provide an operation control device for a vacuum pump and a method for stopping the operation of the vacuum pump that make it possible to effectively remove products, resulting from solidification and liquefaction of gas in a casing and possibly hindering the rotation of a pump rotor, so that the vacuum pump may be started normally. An operation control device 10 for a vacuum pump having a pump rotor 1 disposed in a casing 2 for free rotation includes a pump rotor control section 15 for controlling the rotation of the pump rotor 1. The pump rotor control section 15 has a function to, after a pump stop action has been taken, rotate the pump rotor 1 in forward and/or reverse directions according to a predetermined timing pattern and then stop the pump rotor 1.
摘要:
A method for manufacturing a coffee extract is provided which method enables flavor ingredients of coffee to be extracted separately from bitter ingredients. A coffee extract is obtained by a method including a) a step of placing coffee granules in a granule container part substantially sealed by a restraining member, b) a step of guiding an extraction solvent from a first direction into the granule container part for extraction, and c) a step of retrieving, from the first direction, a coffee extract stored in the granule container part.
摘要:
Production of a yarn, using a spinneret having numerous spinning holes arranged in a straight line(s), and a spinning tube installed below it, spaced from it, and having a filament passage rectangular in cross section with its long side direction agreeing with the direction in which the spinning holes are arranged side by side, wherein gas is injected from the injection holes formed on both the long sides of the filament passage for injecting gas obliquely downward to the filaments, for disposing the numerous filaments in a row and for forming a gas stream flowing downward in the filament passage, characterized in that the speed of the gas stream flowing downward in the filament passage is not less than 60% of the take-up speed of the numerous filaments, or that the gas generated from the numerous filaments is sucked and discharged outside, in the range between the spinneret and the spinning tube. Even if the yarn runs at a high speed, the obtained yarn can have a high elongation.
