Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
72 words
Clabber-free xanthan gum, wherein a milled emulsion consisting essentially of 1.0% said gum, 6.0% vegetable oil, 80% H 2 O, 12% acetic acid (10%), and 1% KCl exhibits at room temperature a working yield value at a shear stress of 0.01 sec -1 at least 50% less than a control emulsion consisting essentially of 1.0% unsheared xanthan gum, 6.0% vegetable oil, 80% H 2 O, 12% acetic acid (10%), and 1% KCl.
Claim 2
Dependent Claim
72 words
Clabber-free xanthan gum, wherein a milled emulsion consisting essentially of 1.0% said gum, 6.0% vegetable oil, 80% H 2 O, 12% acetic acid (10%), and 1% KCl exhibits at room temperature a working yield value at a shear stress of 0.01 sec -1 at least 50% less than a control emulsion consisting essentially of 1.0% unsheared xanthan gum, 6.0% vegetable oil, 80% H 2 O, 12% acetic acid (10%), and 1% KCl.
Claim 3
Dependent Claim
31 words
Clabber-free xanthan gum wherein a milled emulsion consisting essentially of 1.0% said gum, 6.0% vegetable oil, 77% H 2 O, 3% NaCl, and 13% acetic acid (10%) exhibits smooth flow properties.
Claim 4
Dependent Claim
31 words
Clabber-free xanthan gum wherein a milled emulsion consisting essentially of 1.0% said gum, 6.0% vegetable oil, 77% H 2 O, 3% NaCl, and 13% acetic acid (10%) exhibits smooth flow properties.
Claim 5
Dependent Claim
14 words
A process for producing clabber-free xanthan gum which comprises shearing pasteurized xanthan gum beer.
Claim 6
Dependent Claim
14 words
A process for producing clabber-free xanthan gum which comprises shearing pasteurized xanthan gum beer.
Claim 7
Dependent Claim
31 words
The process of claim 3 where the shearing is comparable to that produced by passing the undiluted beer at room temperature twice through a Manton-Gaulin Model 15M homogenizer at 7500 psi.
Claim 8
Dependent Claim
18 words
The process of claim 4 which comprises the further step of precipitating the clabber-free xanthan gum with isopropanol.
