The Importance of Freshness in Lemon Zest
The freshness of lemon zest plays a significant role in its flavor and aroma. Freshly zested lemons have a more vibrant and intense flavor compared to zest that has been stored for a period. This is because the oil glands in the zest are prone to oxidation, which can lead to a loss of flavor and aroma over time. To maintain the quality of lemon zest, it’s essential to store it properly, which brings us to the question of refrigeration.
Factors Affecting the Shelf Life of Lemon Zest
Several factors can influence the shelf life of lemon zest, including the method of zesting, storage conditions, and handling practices. <strong。しかし, the primary factor affecting the shelf life of lemon zest is exposure to oxygen, which can cause the oil glands to oxidize and lose their potency.
