Daily Food Tip & Recipe
Is the nutritional value of protein lost through cooking and storing of food just as vitamins are lost?
Proteins are not lost during cooking as easily as vitamins; however overcooking and cooking at extremely high temperatures will denature proteins found in food. When cooked or agitated (as occurs when egg whites are beaten), proteins undergo physical changes called denaturation and coagulation. Denaturation changes the shape of the protein, decreasing the solubility of the protein molecule. Coagulation causes protein molecules to clump together, as occurs when making scrambled eggs. Overcooking foods containing protein can destroy heat-sensitive amino acids (for example, lysine) or make the protein more resistant to digestive enzymes. Refrigerating cooked foods will not further denature the proteins.
Barley Risotto & Fennel From Eating Well
Ingredients
2 teaspoons fennel seeds
1 large or 2 small fennel bulbs, cored and finely diced, plus 2 tablespoons chopped fronds
1 cup pearl barley or short-grain brown rice
1 small carrot, finely chopped
1 large shallot, finely chopped
2 cloves garlic, minced
4 vegetable broth
1-1 1/2 cups water, divided
1/3 cup dry white wine (or white grape juice)
2 cups frozen French-cut green beans
1/2 cup grated Parmesan cheese (or vegan parmesan)
1/3 cup pitted oil-cured black olives, coarsely chopped
1 tablespoon freshly grated lemon zest
Freshly ground pepper to taste
Directions
- Coat a 4-quart or larger slow cooker with cooking spray. Crush fennel seeds with the bottom of a saucepan.
- Combine the fennel seeds, diced fennel, barley (or rice), carrot, shallot and garlic in the slow cooker. Add broth, 1 cup water and wine, and stir to combine. Cover and cook until the barley (or rice) is tender, but pleasantly chewy, and the risotto is thick and creamy, 2 1/2 to 3 1/2 hours on high or low.
- Shortly before serving, cook green beans according to package instructions and drain.
- Turn off the slow cooker. Stir the green beans, Parmesan, olives, lemon zest and pepper into the risotto. If it seems dry, heat the remaining 1/2 cup water and stir it into the risotto.
- Serve sprinkled with the chopped fennel fronds.
Serves 6.
