Jam is a gel made by mixing fruit, sugar, and an acidity regulator and boiling it over 100℃.
Making jam is one way to preserve fruit for a long time. Jam is mainly used to spread on bread or toast. Whether strawberry, blueberry, grape, rose, and other small fruits, or plum, orange, apple, peach, and other large fruits cut small, the same can be made into jam.
Sugar-free jam, cheap jam, or special jam (e.g. durian, pineapple), will use colloids. The colloids commonly used in jam include pectin, and bean gum.
Jam contains natural fruit acids, which promote the secretion of digestive juices. It has the effect of increasing appetite and helping digestion. Jam can also help with iron deficiency anemia.
Jam is rich in potassium and zinc, which can eliminate fatigue and enhance memory. Infants who eat jam can supplement calcium, and phosphorus, and prevent rickets.
Jam is usually made in a ratio of one part pulp to half part sugar. The amount of sugar can be increased or decreased appropriately. Sugar thickens jam and is a good preservative. Using too little sugar can shorten shelf life.
If the amount of sugar is moderate, the well-sterilized jam will last for more than 6 months. If it is less water content fruit such as apples, pears, etc., can be added half a portion of water. Jam pot is best to be acid-resistant, such as blueberries, and hawthorn, and can not be cooked in iron or aluminum POTS. Be careful to keep stirring while cooking, preferably with a wooden spoon.
Jam containers are best made of glass, and should be boiled in boiling water for five to ten minutes before use (do not use towels to wipe). The jam should be put into the container while it is hot, cover tightly, placed upside down, and leave at room temperature with the mouth facing up (this can prevent air from entering the bottle and make the bottle vacuum). Best stored in the refrigerator.
