摘要:
A process for producing an eriocitrin-containing material comprises the steps of: preparing an eriocitrin-containing citrus extract from a citrus fruit using an extractant; and separating eriocitrin from the citrus extract. The step of separating eriocitrin from the citrus extract comprises the steps of: bringing the citrus extract into contact with a porous synthetic adsorption resin such that eriocitrin in the citrus extract is adsorbed on the porous synthetic adsorption resin, the porous synthetic adsorption resin comprising a phenol-formaldehyde resin as a main framework and having amino and phenolic hydroxyl groups; and eluting the eriocitrin adsorbed on the porous synthetic adsorption resin using an elution solvent.

Forming method of producing thin-walled finished articles such as cups of expanded resin including steps of: heating beads of expandable thermoplastic resin in a mold cavity of a preforming mold, causing the beads to be expanded and fused together to produce a preformed article; transferring the preformed article as pressurized in an atmosphere under pressure to a finish-forming mold; and compressively forming the preformed article with the finish-forming mold. Also, disclosed in apparatus to be used for embodying the method of forming expanded resin cups, including: a pressure chamber held as pressurized, a preforming mold in which beads of expandable thermoplastic resin introduced in the mold cavity are heated, causing the beads to be expanded and fused together to produce a preformed article; male member transferring means for transferring the male member of the preforming mold together with the preformed article, to a position opposite to the female member of a finish-forming mold; and a finish-forming mold for heating, compressively forming, and cooling the preformed article to produce a thin-walled finished article, with the preforming mold and the finish-forming mold being both disposed in the pressurized chamber.

The present invention relates to a method for producing fruit vinegar, comprising subjecting a flavorful acid citrus fruit juice with an inherently low citric acid content and/or a flavorful acid citrus fruit juice with a reduced citric acid content by acid reduction treatment as a raw material, after alcohol is added thereto by alcohol fermentation and/or addition of alcohol, to acetic acid fermentation; although acetic acid fermentation using a flavorful acid citrus fruit juice with a high citric acid content has been hitherto unsuccessful, the reduction treatment of citric acid content in the present invention has realized an efficient production of fruit vinegar with good body, savory taste and mild sourness that has not been hitherto produced.
