用すると考えられている。Prior art and its problems Gum arabic is widely used as an emulsifier, mainly in the food and pharmaceutical fields. The emulsification mechanism of gum arabic has not yet been fully elucidated, but in a 0/W emulsion system, gum arabic molecules do not act to increase the viscosity of the water layer, but rather gum arabic molecules adsorb to oil droplets and form a film. It is believed that it works.

粘度を上げて、乳化力を高めている。However, it is also known that in a gum arabic emulsion system, increasing the viscosity of the water layer increases the emulsifying power. Therefore, a thickener such as xanthan gum or talacant gum is added to a system in which gum arabic alone has low emulsifying power to increase the viscosity of the aqueous layer of the system, thereby increasing the emulsifying power.

It is a salt of a, Mg, and has a molecular weight of 25,000 to 2,000.
It is about 00. Moreover, the viscosity of its 10% aqueous solution is about 10 cps.

満でも変性物を得ることができるが、変性に長時間を要
するので好ましくない。The method of the invention is carried out by heating arabic acid powder, thereby modifying the arabic acid. The excellent effects of the present invention can only be achieved when arapic acid is heat-modified; for example, similar effects cannot be obtained even when gum arabic is heat-modified. The heating temperature is not particularly limited, but is usually about 100-160°C, preferably 105-160°C.
The temperature may be about 140°C, thereby obtaining a heat-modified product of arapic acid (hereinafter simply referred to as a modified product), that is, a powder of highly viscous gum arabic, whose viscosity of a 10% aqueous solution is about 15 to 4000 cps. . Although a modified product can be obtained at a temperature lower than 100°C, it is not preferable because the modification takes a long time.
