Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
103 words
Concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: (a) 10 to 90 percent by weight citrus peel oil concentrate produced from cold-pressed citrus peel oil, the peel oil concentrate being obtained by subjecting the cold-pressed citrus peel oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate and (b) the remainder essence oil concentrate.
Claim 2
Dependent Claim
103 words
Concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: (a) 10 to 90 percent by weight citrus peel oil concentrate produced from cold-pressed citrus peel oil, the peel oil concentrate being obtained by subjecting the cold-pressed citrus peel oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate and (b) the remainder essence oil concentrate.
Claim 3
Dependent Claim
103 words
Concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: (a) 10 to 95 percent by weight citrus peel oil concentrate produced from cold-pressed citrus peel oil, the peel oil concentrate being obtained by subjecting the cold-pressed citrus oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate and (b) remainder concentrate of an aqueous essence.
Claim 4
Dependent Claim
103 words
Concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: (a) 10 to 95 percent by weight citrus peel oil concentrate produced from cold-pressed citrus peel oil, the peel oil concentrate being obtained by subjecting the cold-pressed citrus oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate and (b) remainder concentrate of an aqueous essence.
Claim 5
Dependent Claim
125 words
Concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: (a) 10 to 90 percent by weight citrus peel oil produced from cold-pressed citrus peel oil, the peel oil concentrate being obtained by subjecting the cold-pressed citrus peel oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the absorbed fraction, recovering the eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate and (b) 5 to 85 percent by weight essence oil concentrate (c) 5 to 85 percent by weight concentrate of an aqueous essence.
Claim 6
Dependent Claim
125 words
Concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: (a) 10 to 90 percent by weight citrus peel oil produced from cold-pressed citrus peel oil, the peel oil concentrate being obtained by subjecting the cold-pressed citrus peel oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the absorbed fraction, recovering the eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate and (b) 5 to 85 percent by weight essence oil concentrate (c) 5 to 85 percent by weight concentrate of an aqueous essence.
Claim 7
Dependent Claim
103 words
A process for producing a concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: forming a mixture containing 10 to 90 percent by weight citrus peel oil concentrate, and the remainder essence oil concentrate, the peel oil concentrate being obtained by subjecting cold-pressed citrus peel oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate.
Claim 8
Dependent Claim
103 words
A process for producing a concentrate of natural citrus oil which retains its aroma and is stable in storage, comprising: forming a mixture containing 10 to 90 percent by weight citrus peel oil concentrate, and the remainder essence oil concentrate, the peel oil concentrate being obtained by subjecting cold-pressed citrus peel oil to adsorption at a solid separating agent which adsorbs polar organic substances to thereby form an adsorbed fraction at the solid separating agent, eluting the adsorbed fraction with a polar organic eluant to form an eluate containing the adsorbed fraction, recovering the eluate, and separating the adsorbed fraction from the eluate.
