Herstellungsverfahren von schnelllöslichem Agar

摘要

The present invention relates to a process for obtaining agar-agar that can be dissolved quickly in water at a temperature higher than its gelling temperature. It consists of using the classical agar-agar in the form of dried powder or dehydrated agar gel granules obtained after the operation of mechanical pressing or of freeze-thawing, and of passing it through a single-screw or twin-screw extruder. The process can be carried out in mixture with principally water and other products such as the locust bean gum, the guar gum, sugar, peptones or dispersants like the metarine, fatty acids or organic silicones. Such process allows to produce, at a reduced price, an agar-agar with properties of instantaneous dissolution in hot water at a temperature higher than its gelling temperature.
