Cooking the vegetables breaks down the cell wall and the plasma membrane. This decreases the turgor pressure of the cell and creates a soft veggie.
Vegetables can be cooked without added salt. But salt causes water to boil at a higher temperature than unsalted water, shortening the cooking time. Salted water also improves the flavor of most vegetables. ---------------------------------------------------------------------------- Heavily salted water boils at about 213F (100.5C). The main reasons for adding salt is to keep starchy foods from sticking, prevent nutrient loss by "sealing" the surface of the food or to enhance the flavor of foods. See link below.
vegetables taste better when the salt has been added during coking rather than from the siler one of the effects of cooking vegetables in salted water is that the flavour is improved... however through the process of osmosis some nutrients can be lost this is because they will be moving out of the vegetable to the outside where there is a higher concentration of salt
They typically form on steep beaches and tend to be more erosive.
It is true to say that it could be either, but most would agree that cooking food is endothermic - food takes in the heat during cooking, and doesn't release it while cooking. The heat is circulated through the food when it is cooking, making it endothermic. Some foods release the heat, but this is only after the food has been cut.Cooking an egg is an endothermic process. The egg absorbs the heat from the water and does not release it. Perhaps if you are making hard boiled eggs you could say that it is both - endothermic while cooking and exothermic while cooking. Though the cooking process is absolutely endothermic.
To stop the cooking and set the color, "refresh" vegetables by immediately draining and plunging them into ice water.
blanching
Blanching works by quickly cooking the food and then quickly stopping the cooking progress. This is usually stopped using ice water.
shocking.
Steaming the vegetables rather than boiling.
does soaking vegetables in water before cooking cause leaching of water soluble vitamins and minerals
I do not enjoy plunging into cold water.
Vacuum packed vegetables are blanched, which is a process of partially cooking them in boiling water. They do this because raw vegetables give off gases when stored. Vacuum packed fruits are uncooked when frozen.
Depending on the vegetables, you can steam them or Blanche them. (Where you put vegetables in boiling water, then put them in ice cold water)
generally food does not contain water and you need water in order to cook them. So at the end of the cooking process water is found in foods. on the other hand fruits and fruit vegetables have a high water content.
I think its so they do not overcook and become mushy. I am not completly sure.
Vitamin C is easily destroyed during preparation, cooking or storage so follow these easy tips to retain as much of the vitamin as possible. * Eat raw fruits and vegetables as soon as possible after buying them. * Cut vegetables just before eating or cooking. * Cook vitamin C-rich foods quickly in as little water as possible. * Microwave, steam or stir-fry to retain the most Vitamin C.
