If you’re boiling, use as little water as possible, and cook for the least possible time. Steaming is great, yes, but steam in small batches to minimise cooking time. Oh, and always cook spuds in their skins – it helps minimise the loss of both vitamin C and other nutrients.
How do you preserve vitamin C when cooking?
Steaming and microwaving retained higher concentrations of vitamin C than boiling because of the reduced contact with water at relatively low temperatures. Using minimal cooking water and cooking for shorter time periods should result in higher vitamin C retention.
Does cooking destroy vitamin C in potatoes?
Dear F.D.: Food preparation methods involving high heat can indeed destroy heat-sensitive (or “heat-labile”) nutrients, which include vitamin C and thiamin (vitamin B1). … That level in the USDA database does reflect an estimated 50% reduction of the amount of vitamin C found in a raw potato.
How should vegetables be prepared and cooked to maintain the vitamin C content?
“By preparing vegetables and not boiling them, water-soluble nutrients, especially vitamin C and the B vitamin folate are retained,” says Kelly Jones MS, RD, CSSD, LDN. “When boiling, those nutrients can be leached out into the water in great amounts, and therefore not eaten,” she says.
Does cooking kill vitamin C?
Vegetables are generally a great source of vitamin C, but a large amount of it is lost when they’re cooked in water. In fact, boiling reduces vitamin C content more than any other cooking method. … Because vitamin C is water-soluble and sensitive to heat, it can leach out of vegetables when they’re immersed in hot water.
At what temp does Vitamin C break down?
Vitamin C begins to denature at temperatures as low as 86 °F, according to a study in the International Journal of Scientific and Technology Research. The negative effects of heat increase significantly at 140 and even more at 170 °F.
Why does vitamin C decrease with temperature?
This suggests that denaturation of vitamin C due to heating depends on its availability in the vegetable. Thus vitamin C being water soluble leaches into cooking water and gets degraded. Vitamin C is important to human health and a necessary dietary source.

Are potatoes rich in vitamin C?
Potatoes are rich in several micronutrients, especially vitamin C – eaten with its skin, a single mediumsized potato of 150 g provides nearly half the daily adult requirement (100 mg). The potato is a moderate source of iron, and its high vitamin C content promotes iron absorption.
Does boiling lemons destroy vitamin C?
A-Ewan Cameron, medical director of the Linus Pauling Institute of Science and Medicine, answering the question about lemon juice and hot water, advises that Vitamin C in solution degenerates over time. This degeneration is faster in hotter solutions, but the Vitamin C is not instantly destroyed.

How do you keep nutrients when cooking?
The three R’s for nutrient preservation are to reduce the amount of water used in cooking, reduce the cooking time and reduce the surface area of the food that is exposed. Waterless cooking, pressure cooking, steaming, stir-frying and microwaving are least destructive of nutrients. Frozen vegetables can be steamed.
Does refrigeration destroy vitamin C?
There is another wrinkle: vitamin C is destroyed not only by heat but also by light and oxygen. Studies have shown that vitamin C continues to disappear in the refrigerator. Further, vitamin C disappears faster at 50°F (10°C) compared to 40°F (~4°C) or lower.
Does microwave destroy vitamin C?
“Vitamin C is more heat-sensitive than many other water-soluble vitamins and antioxidants, so you do run the risk of losing some C when you reheat your leftovers,” says upwave reviewer Caroline Kaufman, M.S., RDN.
Does cooking blackcurrants destroy vitamin C?
How much vitamin C should we eat? … Being water-soluble, some vitamin C is lost when cooked. Raw fruit and vegetables will contain the most vitamin C but if you need to cook them at all then steaming appears to be the best method for retaining the most nutritional value.
