Claims3
An edible material comprising an isolated, stable compound of general formula (2) or a salt thereof:
- wherein in general formula (2),
- R21, R23, R26-R28, and R213-R216 are each independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, cycloalkyl, substituted cycloalkyl, aryl, substituted aryl, heterocyclyl, substituted heterocyclyl, heteroaryl, and substituted heteroaryl, wherein any of R21, R23, R26-R28, and R213-R216 are optionally joined to form a ring, wherein the ring is optionally substituted;
- R29 and R210 are each independently selected from the group consisting of hydrogen, an alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, cycloalkyl, substituted cycloalkyl, aryl, substituted aryl, heterocyclyl, substituted heterocyclyl, heteroaryl, substituted heteroaryl, and C(=0)R211, wherein R29 and R210 are optionally joined to form a ring;
- each occurrence R211 is independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, cycloalkyl, substituted cycloalkyl, aryl, substituted aryl, heterocyclyl, substituted heterocyclyl, heteroaryl, substituted heteroaryl, a monosaccharide, a disaccharide, and a polysaccharide;
- Y is selected from the group consisting of C(R217R18), NR217, SR217, and
- OR217;
- R217 and R218 are each independently selected from the group consisting of hydrogen, alkyl, substituted alkyl, alkenyl, substituted alkenyl, alkynyl, substituted alkynyl, cycloalkyl, substituted cycloalkyl, aryl, substituted aryl, heterocyclyl, substituted heterocyclyl, heteroaryl, substituted heteroaryl, halogen, and hydroxyl;
- m is an integer from 0 to 11;
- p is an integer from 0 to 5;
- q is an integer from 1 to 5;
- and
- X21 is selected from the group consisting of O, NH, and S;
- wherein the edible material is a beverage, and wherein the isolated, stable compound of general formula (2) or salt thereof imparts a color to the beverage;
- and,
- wherein the compound of general formula (2) is present in a concentration between 0.25 mg/ml and 10 mg/ml in the edible material.
