Abstract
Abstract Process of producing confectioned mushrooms by soaking a bundle of mushrooms in one or more tankfuls of a boiling organic acid solution, all at once or in successive tanks, and then sequentially soaking the mushrooms in ever-increasing concentrations of syrup. The obtained soaked mushrooms are then heated, coated with a layer of syrup and dried.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
47 words
The method of claim 1, wherein the bundle of mushrooms is soaked in a series of batches of the boiling carboxylic acid solution for about 15 minutes and thereafter soaked in the successive batches of syrup for a time of approximately 12 to 20 hours per batch.
Claim 2
Dependent Claim
15 words
The method of claim 1, wherein an approximately 1 percent carboxylic acid solution is employed.
Claim 3
Dependent Claim
17 words
The method of claim 1, wherein the mushrooms are soaked in three batches of carboxylic acid solution.
Claim 4
Dependent Claim
21 words
The method of claim 4, wherein the soaking is conducted for approximately 5 minutes in each of the carboxylic acid solutions.
Claim 5
Dependent Claim
12 words
The method of claim 1, wherein said carboxylic acid is citric acid.
Claim 6
Dependent Claim
11 words
The method of claim 1, wherein said anti-crystallization agent is glucose.
Claim 7
Dependent Claim
17 words
The method of claim 1, wherein the mushrooms are heated in step (c) to approximately 80* C.
Claim 8
Dependent Claim
21 words
The method of claim 1, wherein the coating step (d) is conducted using syrup having a concentration of about 78 percent.
Claim 9
Dependent Claim
17 words
The method of claim 1, wherein the drying step (e) is carried out at about 28* C.
Claim 10
Independent Claim
200 words
A method for the preparation of confectioned mushrooms comprising the steps of: a. bringing three batches of an aqueous citric acid solution to boil, b. soaking a bundle of mushrooms in the boiling citric acid solution sequentially in each bath for a period of approximately five minutes in each of the solutions, c. removing the bundle of mushrooms from the last batch of boiling citric acid solution, d. soaking the acid-treated mushrooms in successive batches of syrup maintained at a temperature of approximately 58* C., the concentration of syrup gradually increasing from 45 percent in the first batch to 72 percent in the last batch, said syrup comprising water, sugar, and an anti-crystallization agent, for a period of several hours to replace the water impregnated in the acid solution with syrup, e. heating the obtained mushrooms by a high frequency heating means at a temperature of approximately 80* C. for a time sufficient to uniformly dry both the interior and the surface of the mushrooms, f. coating the resulting mushrooms with a layer of syrup at a temperature of approximately 105* C. to obtain a transparent layer thereon, and g. drying the mushrooms at a temperature of about 28* C.
Claim 11
Dependent Claim
11 words
The method of claim 11, wherein said anti-crystallization agent is glucose.
