Secret culinary.

To cook a meal right for a vitamins keeping,as a problem first.
Warm, chopped potato in water left,will lost in 12 hours as vitamin c till  9 percent, and chopped till 51 percent, and cauliflower in room s temperature loosing  vitamin c till 10 percents/day, at refrigerator that will lost in a week.
And an idea is potato add right away after chopping and cleaning in boiling water,ready dish does not leave on oven, keeping to wish a more hot   kind, in cool, put right away in a refrigerator till warm temperature.

A second problem.
Sun light and air in natural light will lost vitamin c for three times,and idea is salads before eating chopping right away, and on middle pieces,do not buy a chopped vegetables and green, as even this is comfortable.

Third problem is meal cooking as a  long time and warming often leading till 15 percent of vitamins groups B lost, and in meat as 20 percents are vitamins groups B, and 50 percent are groups C in vegetables.And an idea is less culinary cooking they are will keek more vitamins, and a good spare method for theirs is steam cooking, baking, and non hope are boiling and frying.

For the meat frying a vitamins lost is poor, than in boiling, more water,are  poor vitamins keeping in meal, and if lid does not had on pot,and evaporate vitamins, potato in peel coked will lost vitamin c is poor, than a potato cleaned cooked. Folic acid will lost in seeds cleaning, that a better eating a whole cereal meal, as a portion of soup arm in a small pot, do not warm all for three days, and for keeping vitamins in frozen vegetables,cook theirs,as steaming.
