1. WO1992009211 - POLYHYDROXYALKANOATE CREAM SUBSTITUTES

ملاحظة:نص مبني على العمليات الآلية للتعرف الضوئي على الحروف. الرجاء استخدام إصدار PDF لقيمته القانونية

We claim:

1. A method of simulating the mouthfeel of fat and/or cream in a food product which comprises adding to the food a
water-dispersable macrocolloid of substantially non-aggregated PHA particles of the formula

, H0-(CHCH2C00-)x H

wherein
R represents a C1-C12 alkyl which can be the same or different on each repeating monomeric unit and
x represents an integer of from 500 - 17,000

wherein the PHA particles have a substantially spheroidal shape and a mean particle size distribution ranging from about 0.1 microns to 10 microns.

2. The method of claim 1 wherein the PHA is a homopolymer.

3. The method of claim 2 wherein R is methyl.

4. The method of claim 1 wherein the PHA a copolymer of hydroxybutyrate and hydroxyvalerate.

5. The method of claim 1 wherein the PHA is a copolymer or terpolymer.

6. The method of claim 1 wherein the PHA is a copolymer of hydroxybutyrate and a C2-C12 alkanoate.

7. In a food product containing a fat and/or cream, the improvement vhich comprises: substituting for all or a portion of the fat and/or cream, a vater-dispersable macrocolloid of substantially
non-aggregated PHA particles of the formula

H0-(CHCH2C00-)x H

vherein
R represents a C1-C12 alkyl vhich can be the same or different on each repeating monomeric unit and
x represents an integer of from 500 - 17,000

vherein the PHA particles have a substantially spheroidal shape and a mean particlesize distribution ranging from about 0.1 microns to 10 microns.

8. The improved food product of Claim 7 vhich is ice cream, yogurt, salad dressing, mayonnaise, cream cheese, cheese, milk, an icing, a spread, sour cream, coffee vhitener, vhipped topping, cream, or a sauce.

9. The improved food product of Claim 8 which is ice cream.

10. The improved food product of Claim 8 which is salad
dressing.

11. The improved food product of Claim 7 wherein the PHA is a homopolymer.

12. The improved food product of Claim 7 wherein R is methyl.

13. The improved food product of Claim 7 wherein the PHA is a copolymer of hydroxybutyrate and hydroxyvalerate.

14. The improved food product of Claim 7 wherein the PHA is a copolymer or terpolymer.

15. The improved food product of Claim 7 wherein the PHA is a copolymer of hydroxybutyrate and a C2-C12 alkanoate.
