Apple jam is a delicious and popular spread made from apples, sugar, and pectin. It’s a staple in many households, and its sweet and tangy flavor makes it a favorite among both children and adults. However, like any food product, apple jam has a limited shelf life, and its quality can degrade over time. In this article, we’ll explore the factors that affect the shelf life of apple jam, how to store it properly, and how to determine if it’s still safe to eat.
Factors Affecting the Shelf Life of Apple Jam
The shelf life of apple jam depends on several factors, including the ingredients used, the manufacturing process, storage conditions, and handling practices. Here are some of the key factors that can affect the shelf life of apple jam:
