Malvin is a naturally occurring chemical of the Anthocyanin family. It is a diglucoside of malvidin mainly found as a pigment in herbs like Malva (Malva sylvestris), Primula and Rhododendron. The characteristic floral jade coloration of Strongylodon macrobotrys has been shown to be an example of copigmentation, a result of the presence of malvin and saponarin (a flavone glucoside) in the ratio 1:9.
Presence in food
Malvin can be found in a variety of common foods, including but not limited to the following:
- Vegetables: avocado, beet, black eyed pea, cabbage, carrot, eggplant, green pea, maize, olive (green and black), onion, pimento, potato, radish, tomato, turnip
- Nuts: cashew, walnut
- Herbs/Spices: paprika, mustard seed, cinnamon
- Fruit: apple, fig, watermelon, rhubarb, strawberry, quince, peach (Clingstone variety), pear, plum, grape (red and green), apricot, banana, blackberry, blueberry, boysenberry, cherry, cranberry, black currant
- Fish: crabmeat
- Dairy: albumin (cow's milk), cheese, yogurt, butter

Malvin is not dangerous to ingest unless one develops an allergy toward it. An allergy to malvin may result in constipation, severe gas, vomiting or diarrhea when foods containing it are ingested in large amounts.
