Strawberry jam refers to a jam made with strawberries as the main ingredient. The berries are cut into small pieces or crushed and cooked in sugar syrup. The preparation of strawberry jam traditionally involves the use of pectin as a gelling agent,although sugar or honey may be used as well. Strawberries are rich in fiber, vitamin C, Vitamin A and potent antioxidants. Strawberries are an excellent source of vitamins C and K as well as providing a good dose of fibre, folic acid, manganese and potassium. Strawberry jams do not contribute to the cholesterol and fat content and are thus a preferred breakfast accompaniment. Pectin is a substance contained in all fruits. During the heating process of making jams, this substance gets modified. The modified pectin helps in reducing your chances of having cancer.
