How To Preserve Vitamin C In Food When Cooking
Vitamin C is one of the essential nutrients needed by our body. Vitamin C is lost when food is cooked on heat and water. Steaming or microwaving food retains Vitamin C. Also, cook food at low temperatures with less water to allow the Vitamin C to be retained in higher amounts.
Effect of cooking method on vitamin C content in vegetables The nutritional value of vitamin C (1-ascorbic acid; 2,3-enediol-1-gulonic acid-g-lactone) as the main water-soluble vitamin is well known.
What is the best cooking method to preserve nutrients?
Steaming is one of the best cooking methods for preserving nutrients, including heat- and water-sensitive water-soluble vitamins (4, 5, 6, 17). That’s why steaming is one of the best ways to preserve easily degradable nutrients like vitamin C and many B vitamins.
Vegetables rich in water-soluble vitamins, especially vitamins C and B, tend to be more sensitive to cooking and prone to nutrient loss. Water-soluble vitamins like vitamins B and C are leached out when boiled, so steam vegetables with a little water on the stovetop or in the microwave instead of boiling.
To preserve vitamins like C and B, cook vegetables in as little water as possible for the minimum amount of time (unless you plan to consume water, for example, in soup). The water used during cooking traps the vitamins released from the food and some of its flavour.

Since vegetables do not come into contact with water when steamed, more vitamins are retained. Draining, in turn, means that vitamins have been scattered into the wind and fats have been added to vegetables.
This is because when we cook vegetables in water or other liquids and add butter or other oils during the cooking process, everything drains before the dish reaches the table.
Drink the water used for boiling vegetables for nutrients
If you don’t drink water prepared for cooking, you won’t get the nutrients you think you should get from vegetables. Boiling delicate foods such as vegetables in large amounts can destroy some nutrients and allow others to seep into the cooking water. If you want your vegetables to cool down, don’t immerse them in an ice bath; like hot water, cold water can also leach nutrients.
Because vitamin C is water-soluble and sensitive to heat, soaking vegetables in hot water releases vitamin C. Vitamin C is a water-soluble, temperature-sensitive vitamin.
It thus is easily degraded during cooking, and high temperatures and prolonged cooking can lead to particularly severe vitamin C losses. This means that vitamin C is easily broken down during cooking, and prolonged cooking reduces the amount of vitamin C in foods.
| Methods | Result |
| Instead of boiling the vegetables, steaming them in a little amount of water | More vitamins are retained |
| Cooking at a high temperature | At least it can lessen the loss of vitamin C |
| Cooking food in the microwave | More vitamins are retained |
An adequate dietary intake of vitamin C is vital for the normal functioning of the human body. You can conserve vitamin C by eating raw, freshly cooked food, using less water in cooked food, etc.
Food is critical to getting the body’s vitamins, minerals and nutrients. body, work and be healthy. Surprisingly, how you prepare food greatly impacts the amount of nutrients it contains.
You can conserve vitamin C by cooking food in very little water (such as steaming or microwaving) and eating fresh fruits and vegetables as soon as possible.
Fresh or frozen fruits and vegetables contain more nutrients than canned ones (canning can cut some vitamins in half). However, in many climates, fresh local produce is limited during winter, and buying frozen or even canned fruits and vegetables can save more nutrients.
However, when you cook fruits and vegetables, you run the risk of getting rid of some of these nutrients during the cooking and heating process, so your body won’t be able to absorb the maximum amount of them.
should you microwave vegetables?
Meanwhile, about 20-30% of the vitamin C in green vegetables is lost in the microwave, which is less than most cooking methods. Loss of most vitamins, including vitamin C, is minimal using this preparation method. However, prolonged cooking at high temperatures can reduce the B vitamins in fried meats by up to 40%.
Cooked vegetables that are reheated after being refrigerated for two to three days lose more than half their vitamin C. Steaming vegetables lose, on average, one-third of their vitamin C. Boiled water is not ideal; only 45% of vitamin C and vitamin C are retained on average.
Steaming and microwave cooking retain a higher concentration of vitamin C than boiling due to less contact with water at relatively low temperatures.
Steam cooking allows heated water to gradually soften foods without removing all of the vitamin C. Microwave cooking, while not considered particularly difficult, can also help preserve the vitamin C content of vegetables.
Minimal use of water for cooking and cooking for shorter periods of time should result in increased retention of vitamin C.
Brief cooking without water prevents the loss of B vitamins and added fat promotes absorption of plant compounds and antioxidants (6, 13, 14). Boiling can lead to a large loss of water-soluble vitamins such as folate, vitamins B1 and C, so Chen suggests that steaming and microwave heating are good ways to reduce the loss of vitamins.
Cooking methods can limit the intake of vitamins, affecting the health value of certain foods essential to the body’s metabolism. While several studies have focused on how cooking alters vegetables’ nutritional and phytochemical composition, few have investigated true vitamin retention after exposure to various cooking methods.

This study assessed the effect of several cooking methods on the vitamin content of vegetables, including blanching, boiling, microwaving, and steaming.
Cooked vegetables sometimes contain higher levels of fat-soluble vitamins, including alpha-tocopherol and beta-carotene, than fresh vegetables, but this depends on the type of vegetable.
Cooking fresh beets and perilla leaves resulted in significant changes in vitamin K content, with vitamin K concentrations tending to be higher in cooked vegetables than in the corresponding raw samples, although this was not consistent across all comparisons.
This is the least efficient way to preserve nutrients, especially vitamin C. If you’re cooking vegetables, use as little water as possible and don’t throw away the liquid from cooking the vegetables.
Deep frying vegetables
Conversely, deep frying preserves vitamins C and B, and frying can also increase the fibre in potatoes by converting their starch to resistant starch.
While baking soda helps maintain colour, vitamin C is lost in the alkaline environment created by baking soda. Some nutrients, especially vitamin C, are destroyed during heating, so reheating with a quick microwave is ideal.
How do you cook vegetables without losing vitamin C?
Cooking with little water will help. Using a microwave could also prevent the breakdown of nutrients like Vitamin C because of its low water requirement in addition to the heating process. Frying food with a small amount of fat using extra-virgin olive oil is another way to cook vegetables.
How to preserve vitamin C in food?
Lengthy storage periods and cooking the food in boiling water can cause a loss of vitamin C. With a microwave or steam, there will be minimal utilization of water alongside the preservation of vitamin C. Additionally, fresh fruits and vegetables should be consumed soon to take in more vitamins.
Does cooking destroy vitamin C?
Vitamin C can be ruined by heat, and High-heat cooking temperatures or extended cook times and exposure to air can damage the vitamin. It is suggested that foods with vitamin C be cooked as quickly as possible with less heat and a little water.
