Factors Influencing Shelf Life of Grapefruit Juice

The shelf life of grapefruit juice is influenced by various factors that impact its freshness, flavor, and overall quality. Understanding these factors can help consumers make informed choices about storage and consumption.

Here are key factors that influence the shelf life of grapefruit juice:

1. Processing Methods

Freshly squeezed grapefruit juice may have a shorter shelf life due to the presence of natural enzymes. In contrast, commercially processed juices often undergo pasteurization or other preservation methods to extend longevity.
