ESTERIFIED STARCH AND STARCH-CONTAINING PLASTIC COMPOSITION

NºPublicación: EP3505539A1 03/07/2019

Solicitante:

JAPAN CORN STARCH CO LTD [JP]

Resumen de: EP3505539A1

There is provided esterified starch which can be produced without using a non-aqueous organic solvent and has water resistance and miscibility with another plastic, and a starch-containing plastic composition. The esterified starch is obtained such that a starch mixture containing starch and a polyhydric alcohol, which is subjected to a heat treatment, is esterified with a vinyl ester and carbonate. Since the starch in the starch mixture enters a state in which starch granules are disintegrated by the polyhydric alcohol, by heating the starch mixture containing starch and a polyhydric alcohol, it is possible to esterify the starch without using a non-aqueous organic solvent and to obtain esterified starch having a high ester substitution degree. According to the esterified starch of the present invention, it is possible to obtain a starch-containing plastic composition having high hydrophobicity, and excellent water resistance and miscibility with another plastic.

A beverage cartridge

NºPublicación: PL2862816T3 28/06/2019

Solicitante:

DOUWE EGBERTS BV [NL]

ES_2682674_T3

Resumen de: GB2454656A

The present invention concerns cartridges for producing beverages, especially coffee beverages, that have a fine bubble foam on the surface of the beverage, known as crema. In the beverage flow path within the cartridge there is a curved or angular eductor channel and a downstream cyclonic chamber. Beverage passing through the cartridge from the annular channel 69 is forced into a high velocity jet into the educator channel 80 where air is incorporated from an air inlet 71. A deflector channel downstream of the aperture imparts an asymmetrical flow to the beverage, and there is at least one impact surface 81b onto which the jet of beverage impinges to complete entrainment of the air bubbles. After exiting the educator channel the flow of beverage circulates within zone 93 where it is encouraged into a cyclonic flow pattern for delivery into a receptacle. Control fins may be present in the cyclonic chamber to produce a more directable and confined flow of beverage with less splashing. The quality and/or quantity of crema produced by the cartridge may be modified by varying parameters associated with the educator channel, the air inlet or the jet of beverage.
