摘要:
A granulating method is a method in which powder containing a water-soluble component is granulated. In the disclosed granulating method, a dispersion element, wherein fine water droplets are dispersed in superheated steam, is expelled from a nozzle, and thus the dispersion element and powder in a flowing state come into contact with one another. It is preferable that the mass ratio of superheated steam contained in the dispersion element, as a mass ratio found from the theoretical flow amount of superheated steam expelled from the nozzle, and the actual flow amount of water supplied to the nozzle, be set in a range of 20-70 mass%.

Provided is a method for analyzing a dispersion made by dispersing a liquid or solid dispersoid into a liquid dispersion medium. The method includes the steps of: preparing a sample liquid from the dispersion by forming an agglomerate of the dispersoid in the dispersion medium; redispersing the dispersoid that forms the agglomerate in the sample liquid into the dispersion medium of the sample liquid; and measuring the amount of the dispersoid that has been redispersed from the agglomerate in the sample liquid.
摘要:
The present invention provides a process for producing a powdered drink characterized by subjecting a liquid food to electrolysis treatment and/or current passage treatment, and drying and powdering, further allowed by granulating, if necessary. As the liquid food, coffee extract, coffee essence (concentrated coffee extract), milk, pretreated milk and etc. may be used. The instant coffee obtained in the invention can be preserved for a long period of time without deterioration of flavor or quality, without using a food additive.
摘要:
The invention is to provide a process for producing a liquid food, characterized by subjecting at least one of coffee, a milk composition, a food material (liquid) containing a component(s) having an antioxidation ability (radical-scavenging activity) and mixed liquids containing one(s) of them to an electrolysis treatment and/or a current passage treatment. Since the invention can prevent quality deterioration of coffee or milk composition over a long period of time without using additives and also improve safety, it is appropriate for producing canned coffee, milk-containing coffee or milk-containing tea drink to be sold in vending machines or can warmers. Further, since the invention can improve the antioxidation ability of foods, the resulting foods can suppress the in-vivo increase of active oxygen and free radicals, it greatly contributes to health.

A powdered drink brewing bag comprising a filter paper bag body 1 having gores 2, 2 and containing a powdered material 11, such as coffee powder therein, a frame type support member 4 formed of thick paper and bonded to the portions of the bag body 1 which is in the vicinity of the upper edge thereof in such a manner that the bag body 1 is held at both surfaces thereof between the opposite surfaces of the support member 4, and arm portions 5, 5 projecting outward from the portions of the support member 4 which correspond to both sides of the filter paper bag body 1, and provided with folds 6, 7 and handles 8 so that the arm portions 5, 5 are bent in the shape of the letter "Y" in plan to enable the gores 2, 2 to be expanded. Accordingly, the upper edge portion of the bag body can be maintained in a largely opened state, so that the hot water can be poured thereinto easily. This enables the brewing bag to be used easily, and a drink, such as coffee to be obtained conveniently.
