Abstract
A food composition thickened or suspended with an heteropolysaccharide known as Biopolymer PS 87 comprises glucose, galactose, mannose, glucuronic acid and fucose. Bipolymer PS 87 is pseudoplastic, has a consistency at 20.degree. C. of at least 150 poise and a yield stress value at 20.degree. C. of at least 30 dynes/cm.sup.2. Biopolymer PS 87 is synthesized by a strain of Bacillus polymyxa or a genetically similar micro-organism.
Claims6
An edible composition comprising a thickening or suspending amount of Biopolymer PS 87 wherein said Biopolymer PS 87 is a heteropolysaccharide which comprises from 40 to 45% by weight of glucose, from 10 to 20% by weight galactose, from 25 to 30% by weight mannose, from 16 to 13% by weight glucuronic acid and from 0 to 1.5% by weight fucose, a 1% by weight solution of said Biopolymer PS 87 having pseudoplastic properties, a consistency at 20.degree. C. of at least 150 poise and a yield stress value at 20.degree. C. of at least 30 dynes/cm.sup.2.
A salad dressing comprising a thickening or suspending amount of Biopolymer PS 87 wherein said Biopolymer PS 87 is a heteropolysaccharide which comprises from 40 to 45% by weight of glucose, from 10 to 20% by weight galactose, from 25 to 30% by weight mannose, from 16 to 13% by weight glucuronic acid and from 0 to 1.5% by weight fucose, a 1% by weight solution of said Biopolymer PS 87 having pseudoplastic properties, a consistency at 20.degree. C. of at least 150 poise and a yield stress value at 20.degree. C. of at least 30 dynes/cm.sup.2.
