Abstract
Abstract A novel dextran having a slushy, applesauce-like appearance with a particulate gel-like structure in crude form is described. The dextran is particularly produced by Leuconostoc dextranicum NRRL-B-18242. The dextran in particulate or dried form is used in foods and other applications where texture is important.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
58 words
A composition which comprises Leuconostoc dextranicum NRRL-B-18242 dextran, wherein the dextran is produced in an aqueous sucrose containing growth medium so that the sucrose is essentially depleted and wherein the depleted growth medium containing the dextran has a slushy, applesauce-like appearance with a particulate, gel-like structure and wherein the dextran can be dried so as to be rehydratable.
Claim 2
Dependent Claim
58 words
A composition which comprises Leuconostoc dextranicum NRRL-B-18242 dextran, wherein the dextran is produced in an aqueous sucrose containing growth medium so that the sucrose is essentially depleted and wherein the depleted growth medium containing the dextran has a slushy, applesauce-like appearance with a particulate, gel-like structure and wherein the dextran can be dried so as to be rehydratable.
Claim 3
Dependent Claim
13 words
The composition of claim 1 which has been dried to a rehydratable powder.
Claim 4
Dependent Claim
19 words
The composition of claim 1 which contains a food grade drying aid and has been dried to a powder.
Claim 5
Dependent Claim
13 words
The composition of claim 3 wherein the drying aid is nonfat dry milk.
Claim 6
Dependent Claim
22 words
The composition of claim 3 admixed in a food which is a liquid at room temperatures as a thickener for the food.
Claim 7
Dependent Claim
36 words
The composition of claim 1 admixed in a food which is liquid at room temperatures and solid at refrigeration temperatures or below and wherein the food is eaten as the solid and has an improved texture.
Claim 8
Dependent Claim
13 words
The composition of claim 6 wherein the food is a frozen milk product.
Claim 9
Dependent Claim
12 words
The composition of claim 1 blended with a flavoring for the food.
Claim 10
Dependent Claim
29 words
A composition which comprises dextran produced by a Leuconostoc dextranicum and containing 1,6-glucopyranose with branching about every 11 residues of glucose and having about 2 % by weight fructofuranose.
Claim 11
Dependent Claim
29 words
A composition which comprises dextran produced by a Leuconostoc dextranicum and containing 1,6-glucopyranose with branching about every 11 residues of glucose and having about 2 % by weight fructofuranose.
Claim 12
Dependent Claim
11 words
The composition of claim 9 wherein the Leuconostoc dextranicum is NRRL-B-18242.
Claim 13
Dependent Claim
15 words
The composition of claim 9 wherein the dextran as produced has a particulate, gel-like structure.
Claim 14
Dependent Claim
22 words
The composition of claim 9 wherein the Leuconostoc dextranicum has been grown in a sucrose and non-fat dry milk containing growth medium.
Claim 15
Dependent Claim
61 words
A process for producing a novel dextran which comprises: (a) providing a sucrose containing growth medium; and (b) inoculating the growth medium with Leuconostoc dextranicum NRRL-B-18242 which produces a dextran having a slushy, applesauce appearance with a particulate gel-like structure; and (c) incubating the inocluated growth medium at a temperature of between about 10° to 50° C. to produce the dextran.
Claim 16
Dependent Claim
61 words
A process for producing a novel dextran which comprises: (a) providing a sucrose containing growth medium; and (b) inoculating the growth medium with Leuconostoc dextranicum NRRL-B-18242 which produces a dextran having a slushy, applesauce appearance with a particulate gel-like structure; and (c) incubating the inocluated growth medium at a temperature of between about 10° to 50° C. to produce the dextran.
Claim 17
Dependent Claim
14 words
The method of claim 13 wherein in addition the incubated growth medium is dried.
Claim 18
Dependent Claim
16 words
The method of claim 14 wherein in addition the growth medium is dried by spray drying.
Claim 19
Dependent Claim
16 words
The method of claim 13 wherein in addition the dextran is separated from the growth medium.
Claim 20
Dependent Claim
33 words
The method of claim 16 wherein in addition the dextran is precipitated and removed from the growth medium by adding a solvent to the growth medium which is a non-solvent for the dextran.
