INTRODUCTION

Jam preserves - it's all about preparing delicate and perishable fruits for long-term storage, and it all started several centuries ago.

ORANGE

Citrus fruits have long been valued as part of a nutritious and tasty diet. The flavors provided by citrus are among the most preferred in the world, and it is increasingly known that citrus not only tastes good, but is also good for people.

PECTIN

Pectin is a carbohydrate found in fruits. When sugar is added, the pectin in fruit precipitates out and forms insoluble fibers. An acid, such as citric acid, aids in the process. The insoluble fibers produce a mesh-like structure that traps the fruit juice or other liquid, much like a sponge absorbs water and There are two types of pectin, liquid (usually made from apples) and dry (from citrus fruits or apples).

conclusion

The jam took a while before coming together but with constant stirring to avoid burning the jam came together at the end and was able to scoop out into the jar and was made to cool down before covering it with the lid and it was sealed and kept in refrigerator for proper preservation.
