We did not commission the research. We simply grow what it studied.
Queen Garnet was bred by the Queensland Department of Agriculture and Fisheries through conventional breeding — nothing genetically modified. The studies below were conducted by universities and research institutions, independently of us.

That depth of colour is the point.
The deep purple is anthocyanin — the same family of antioxidants found in blackberries and blueberries. Queensland breeders spent years selecting for more of it. It is the reason this plum exists.

Conventionally bred
Selected over years by Queensland DAF for anthocyanin density. Nothing genetically modified.
No extracts, no isolates
The whole plum goes in and the whole plum comes out — anthocyanins, fibre and polyphenols in roughly the ratio the fruit grew them.

Grown, made and packed in Australia. Certificate of analysis available on request.
Has Queen Garnet plum been studied?
+
Yes — Queen Garnet has been the subject of more than ten peer-reviewed studies published between 2012 and 2021, run by Australian universities and research institutions. PurQ has not funded any of them. Every paper is listed and linked on our research page so you can read the methods and conclusions directly.
What is Queen Garnet plum?
+
Queen Garnet is a Japanese plum cultivar (Prunus salicina) bred in Queensland, Australia by the Department of Agriculture and Fisheries through conventional breeding. It was selected over years for unusually high anthocyanin content — the deep purple pigment found in dark fruit — and is not genetically modified.
What are anthocyanins?
+
Anthocyanins are naturally occurring plant pigments that give blueberries, blackberries and Queen Garnet plums their deep purple-red colour. They belong to the flavonoid group of polyphenols and are the compound class most often examined in the published research on Queen Garnet.
Is Queen Garnet plum genetically modified?
+
No. Queen Garnet was developed through conventional plant breeding by the Queensland Department of Agriculture and Fisheries — selecting and crossing existing Japanese plum varieties over successive generations. No genetic modification was involved.
Does PurQ fund the research on Queen Garnet?
+
No. Every study listed on this page was designed, run and published independently by universities and research institutions. PurQ has funded none of them, and we link each paper so you can read the authors' own methods and conclusions.
Can PurQ make health claims about these studies?
+
No, and we do not. The studies examine anthocyanins and Queen Garnet material in research settings; they are not claims about what PurQ products do. PurQ products are foods, not therapeutic goods, and nothing here is intended to diagnose, treat, cure or prevent any disease.
