Abstract
Abstract A non-soluble monascus pigment, containing principally monascorubrin is first obtained by fermenting a culture of Monascus purpureus or Monascus anka, and is then reacted with one or more members selected from water soluble proteins, water soluble peptides and amino acids to yield the soluble pigment. Alternately, the soluble pigment is produced by fermenting the above mentioned microorganisms in a culture medium containing one or more members selected from water soluble proteins, water soluble peptides and amino acids.

Claim 2
Dependent Claim
26 words

Claim 3
Dependent Claim
25 words
The process of claim 1 wherein said reactant member is an amino acid selected from the group consisting of lysine, arginine, histidine, glustamine, and asparagine.
Claim 4
Dependent Claim
12 words
A water solution monascus pigment formed by the process of claim 1.
Claim 5
Dependent Claim
85 words
A process for producing a water soluble monascus pigment comprising: fermenting a microorganism selected from Monascus purpureus and Monascus anka in a culture medium under aerobic conditions to produce a monascus pigment; separating said microorganisms from said culture medium; extracting a water-insoluble monascus pigment from said separated microorganisms using an organic solvent; and reacting said water-insoluble monascus pigment with a reactant member selected from the group consisting of water soluble proteins, water soluble peptides, amino acids, and mixtures thereof, to produce the water-soluble monascus pigment.
Claim 6
Dependent Claim
29 words
The process of claim 6 additionally comprising: freeze-drying the organic solvent containing said water-soluble monascus pigment to produce a residue; and grinding the residue to form a powder product.
Claim 7
Dependent Claim
30 words
The process of claim 6 additionally comprising: condensing said organic solvent containing said water-soluble monascus pigment under a reduced pressure; and spray-drying the condensed solution to form a powder product.
