and is widely utilized as
a thickening stabilizer. แอลจินิกแอซิด has a structure in
which mannuronic acid and guluronic acid are linearly polymerized, and is commercially available in the form of
a sodium salt, a potassium salt, a calcium salt, an ammonium
salt, or the like. In the present invention, either แอลจินิก
acid or a salt thereof may be used. Any one of sodium alginate and potassium alginate is preferable from the viewpoint of solubility.
An amount of the แอลจินิกแอซิด or salt thereof contained
(blended) in the beverage is 0 . 1 w/v% or more, preferably
0.3 to 5 w/v% in order that the gel strength and the administration easiness can be made excellent, and that the gel can be efficiently increased to a sufficient volume in the stomach.
The term "เจลแลนกัม" refers to a polysaccharide
produced by a microorganism (Sphingomonas elodea)
extracellularly, and is widely utilized as a thickening
stabilizer. เจลแลนกัม is a linear heteropolysaccharide
composed of repeating units each consisting of four sugars
15 of glucose, glucuronic acid, glucose, and rhamnose, and
has a carboxyl group derived from glucuronic acid. There
are two types of gel lan gum: เจลแลนกัมที่ผ่านการกำจัดหมู่เอซิล and native gel lan gum, depending on the presence or absence of an acetyl group and a glyceryl group present in 1-3 linked glucose .
In the present invention, any gellan gum may be used.
เจลแลนกัมที่ผ่านการกำจัดหมู่เอซิล is preferable from the viewpoint of
gel strength.
