Claim 1
Independent Claim
200 words
A process for dehydrating a vegetable to a desired moisture content and a water activity level at 20° C. of from 0.45 to 0.85, comprising the steps of (a) partially dehydrating said vegetable, allowing at least 10% residual moisture to remain; (b) adding to and mixing with the partially dehydrated vegetable a predetermined volume, not exceeding 34.6% by weight of the combined weights of the vegetable and solution, of an aqueous solution containing a known quantity of at least one water activity controlling solute selected from the group consisting of sodium chloride and mixtures of sodium chloride and a sugar, said solution containing no other solutes other than flavorings, coloring substances, seasonings, preservatives, salts, nutritional supplements and anti-oxidants, the quantity of said solution being such that it is totally absorbed by said partially dehydrated vegetable, and the absorption being carried out above 10° C.; and (c) dehydrating said vegetable to a predetermined moisture content and said water activity level in a final dehydration step, the amounts of sugar and sodium chloride in said solution being such that the sugar content of the final dehydrated vegetable is less than 15% by weight and the sodium chloride content is 3-15% by weight.
Claim 2
Dependent Claim
200 words
A process for dehydrating a vegetable to a desired moisture content and a water activity level at 20° C. of from 0.45 to 0.85, comprising the steps of (a) partially dehydrating said vegetable, allowing at least 10% residual moisture to remain; (b) adding to and mixing with the partially dehydrated vegetable a predetermined volume, not exceeding 34.6% by weight of the combined weights of the vegetable and solution, of an aqueous solution containing a known quantity of at least one water activity controlling solute selected from the group consisting of sodium chloride and mixtures of sodium chloride and a sugar, said solution containing no other solutes other than flavorings, coloring substances, seasonings, preservatives, salts, nutritional supplements and anti-oxidants, the quantity of said solution being such that it is totally absorbed by said partially dehydrated vegetable, and the absorption being carried out above 10° C.; and (c) dehydrating said vegetable to a predetermined moisture content and said water activity level in a final dehydration step, the amounts of sugar and sodium chloride in said solution being such that the sugar content of the final dehydrated vegetable is less than 15% by weight and the sodium chloride content is 3-15% by weight.
Claim 3
Dependent Claim
26 words
A process according to claim 1 wherein the vegetable is partially dehydrated in step (a) to the extent where the residual moisture is 10 to 45%.
Claim 4
Dependent Claim
26 words
A process according to claim 2 wherein the partial dehydration step (a) is terminated when rapid dehydration of the vegetable is occurring or has just occurred.
Claim 5
Dependent Claim
22 words
A process according to claim 2 wherein the vegetable is blanched in water or steam prior to the partial dehydration step (a).
Claim 6
Dependent Claim
16 words
A process according to claim 2 wherein said water activity controlling solute is sodium chloride alone.
Claim 7
Dependent Claim
19 words
A process according to claim 5 wherein the final dehydrated vegetable product contains 3-15% sodium chloride and 6-25% water.
Claim 8
Dependent Claim
35 words
A process according to claim 2 wherein sodium chloride and sugar are jointly employed as activity controlling solutes and the final dehydrated vegetable product contains 3-15% sodium chloride, less than 15% sugar and 6-25% water.
Claim 9
Dependent Claim
38 words
A process according to claim 2 wherein said solution of at least one water activity controlling solute also contains at least one additive selected from the group consisting of flavorings, coloring substances, seasonings, preservatives, nutritional supplements and anti-oxidants.
Claim 10
Dependent Claim
22 words
A process according to claim 5 wherein said sodium chloride solute is added in the form of a saturated aqueous solution thereof.
Claim 11
Dependent Claim
22 words
A process according to claim 2 wherein said solution is added at a temperature of about 10° C. to about 55° C.
Claim 12
Dependent Claim
34 words
A process according to claim 2 wherein said vegetable is subjected to a tempering period of from 5 to 30 minutes subsequent to the absorption of said solution and prior to said final dehydration.
