Abstract
Abstract Novel dried compositions containing polysaccharides (dextrans and levans) derived using a Leuconostoc to ferment sucrose to produce the polysaccharides are described. In particular, dried compositions incorporating milk solids or other drying aids to facilitate drying and rehydration of the polysaccharides are described. The compositions are useful as quality (e.g. texture, stability or thickness) improvers for foods.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
102 words
A dried powder composition which comprises in admixture: (a) finely divided, good grade drying aid; and (b) polysaccharides derived by fermenting an aqueous growth medium comprising sucrose with a Leuconostoc dextranicum which produces substantially rehydratable polysaccharides from the sucrose until the sucrose is substantially depleted so as to produce a thickened dextran containing aqueous mixture and so as to allow drying of the fermented growth medium to a powder with the drying aid and then drying the aqueous mixture to the powder, wherein the composition is rehydratable to the thickened dextran containing aqueous mixture and wherein the composition is useful in foods.
Claim 2
Dependent Claim
102 words
A dried powder composition which comprises in admixture: (a) finely divided, good grade drying aid; and (b) polysaccharides derived by fermenting an aqueous growth medium comprising sucrose with a Leuconostoc dextranicum which produces substantially rehydratable polysaccharides from the sucrose until the sucrose is substantially depleted so as to produce a thickened dextran containing aqueous mixture and so as to allow drying of the fermented growth medium to a powder with the drying aid and then drying the aqueous mixture to the powder, wherein the composition is rehydratable to the thickened dextran containing aqueous mixture and wherein the composition is useful in foods.
Claim 3
Dependent Claim
13 words
The composition of claim 1 wherein the drying aid is milk solids, non-fat.
Claim 4
Dependent Claim
12 words
The composition of claim 1 wherein the Leuconostoc is Leuconostoc dextranicum NRRL-B-18132.
Claim 5
Dependent Claim
20 words
The composition of claim 1 wherein the growth medium contains milk solids and wherein milk solids are the drying aid.
Claim 6
Dependent Claim
48 words
The composition of claim 5 wherein the fermentation has been conducted at between about 15° and 35° C. and wherein the growth medium contains between about 5 and 15 percent by weight of sucrose and the milk solids in an amount between 4 and 15 percent by weight.
Claim 7
Dependent Claim
19 words
The composition of claim 6 wherein the milk solids are in non-fat dry milk, skim milk or condensed milk.
Claim 8
Dependent Claim
9 words
The composition of claim 1 which is spray dried.
Claim 9
Dependent Claim
18 words
The composition of claim 1 wherein the powder contains between about 1 and 5 percent by weight moisture.
Claim 10
Dependent Claim
31 words
The composition of claim 1 wherein the growth medium contains milk solids and powdered milk solids have been added to the fermented mixture as the drying aid prior to the drying.
Claim 11
Dependent Claim
29 words
The composition of claim 1 wherein in addition a diacetyl producing bacterium is fermented in the growth medium with a citrate to produce a diacetyl flavor in the composition.
Claim 12
Independent Claim
113 words
A method for forming a dried composition useful as an edible quality improver for foods which comprises: (a) providing an aqueous growth medium containing sucrose; (b) fermenting a Leuconostoc dextranicum which produces substantially rehydratable polysaccharides in the growth medium to produce the polysaccharides in the growth medium until the sucrose is substantially depleted so as to produce a thickened dextran containing aqueous mixture and so as to allow drying of the fermented growth medium to a powder; and (c) drying the growth medium with a food grade drying aid to produce the dried composition with the polysaccharides as the powder, wherein the composition is substantially rehydratable to the thickened dextran containing aqueous mixture.
Claim 13
Independent Claim
113 words
A method for forming a dried composition useful as an edible quality improver for foods which comprises: (a) providing an aqueous growth medium containing sucrose; (b) fermenting a Leuconostoc dextranicum which produces substantially rehydratable polysaccharides in the growth medium to produce the polysaccharides in the growth medium until the sucrose is substantially depleted so as to produce a thickened dextran containing aqueous mixture and so as to allow drying of the fermented growth medium to a powder; and (c) drying the growth medium with a food grade drying aid to produce the dried composition with the polysaccharides as the powder, wherein the composition is substantially rehydratable to the thickened dextran containing aqueous mixture.
Claim 14
Dependent Claim
12 words
The method of claim 11 wherein the Leuconostoc is Leuconostoc dextranicum NRRL-B-18132.
Claim 15
Dependent Claim
21 words
The method of claim 11 wherein milk solids are incorporated in the growth medium as the drying aid for the drying.
Claim 16
Dependent Claim
45 words
The method of claim 11 wherein the fermentation is conducted at between about 15° and 35° C. and wherein the growth medium contains between about 5 and 15 percent by weight sucrose and milk solids in an amount between 4 and 15 percent by weight.
Claim 17
Dependent Claim
12 words
The method of claim 14 wherein the drying is by spray drying.
Claim 18
Dependent Claim
24 words
The method of claim 11 wherein powdered non-fat dry milk solids are added to the growth medium as the drying aid prior to drying.
Claim 19
Dependent Claim
47 words
The method of claim 16 wherein the fermentation is conducted at between about 15° and 35° C. and wherein the growth medium contains between about 5 and 15 percent by weight sucrose and the non-fat dry milk in an amount between 4 and 15 percent by weight.
Claim 20
Dependent Claim
12 words
The method of claim 17 wherein the drying is by spray drying.
Claim 21
Dependent Claim
30 words
The method of claim 11 wherein in addition a diacetyl producing bacterium is fermented in the growth medium with a citrate to produce a diacetyl flavor in the dried composition.
