Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
61 words
In a method of decaffeinating coffee wherein caffeine-containing green coffee is contacted with an extraction medium comprised of a water extract of green coffee solubles to effect caffeine removal from said coffee, the improvement comprising adding sucrose to said extraction medium in an amount sufficient to result in a decaffeinated green coffee having at least about 6% sucrose by dry weight.
Claim 2
Dependent Claim
