The effects of pH under model conditions (0.6 to 5.5 for 24 hr) were covered by Nielsen et al. for four anthocyanins (3-O-glucoside, glycosylated cyanidin, rutinoside, and delphinidin rutinoside). After 24 hr, over 90% of the anthocyanins were intact up to pH 3.3, while instabihty greatly increased at pH greater than 4.5. 

Whereas the anthocyanins bear hues from orange (pelargonidin) to red (cyanidin) to blue (delphinidin), the betalains may be subdivided into distinct yellow-orange (betaxanthins) and red-violet stractures (betacyanins). On the other hand, betalainic... 

Six anthocyanidins are commonly found in plants and plant-derived foods and beverages pelargonidin, cyanidin, delphinidin, peonidin, petunidin, and malvidin. Their structures differ in the number and position of hydroxyl and methoxyl groups on the flavan nucleus. The most commonly occurring anthocyanidin is cyanidin, and all these anthocyanidins are found in plants as glycosides with or without acylation, leading to around 400 different stractures.

Despite the fact that a-L-rhamnosylpyranoside usually occurs in the anthocya-nins as the dissacharide rutinose, a-rhamnose was found in acerola, linked at position 3 to cyanidin and pelargonidin and to delphinidin in Vaccinium padifolium blueberries,and at the 5 position in black raspberries, " red raspberries, " and purple mashua. The D- and L-configurations were not assigned in any of these studies. 

The color stability of strawberry syrup with or without fortification with anthocyanins from black currants (cyanidin and delphinidin 3-glucosides and 3-rutino-sides) and/or AA with levels equivalent to those existing in black currant syrup was investigated. Black currant-fortified strawberry anthocyanins showed higher stability the addition of AA diminished stability. ...

Berries, such as blueberries, bilberries, and black currants, are the main sources of cyanidin, delphinidin, malvidin, peonidin, and petunidin. Malvidin is the characteristic anthocyanidin of red grape and red wine. Plums, cherries, and red cabbage are rich in...
