RE: HYB: Mystery Blush

Not sure how to acidify. Read about it but no info re procedure. Your idea sounds good to me allthough extracting with water works well for anthocyanins and flavanoids and they last for several days. I have used an open flower and removed one petal for exrtraction. Sort of having your cake and eating it too.

Thanks Chuck.  Not sure I have the courage to sacrifice a whole fresh
flower this time of year.  Color seems to have stayed the same, but who
knows what it would have been with a fresh flower.

Just to make sure I understand - first extract with water to get
anthocyanins, then alcohol to get other water/alcohol soluble pigments?
So the anthocyanins will come out in the water, then the
orange/yellow/pink whatever is left can be extracted with alcohol?

Is distilled vinegar a suitable acidifier?  How much?  One drop per
tablespoon?

<Use straight water, preferable distilled. Fresh flower works best. On
older flowers there is some decomposition of flower which remains in
solution and pigment also has deterioated. Alchohol extraction of water
based pigments can be a problem as they often degrade very quickly
unless the alcohol is slightly acidified
                  Hope this helps
