Orange marmalade can taste bitter due to the presence of the orange peel, which contains compounds like limonin and naringin that contribute to the bitterness. These compounds are more concentrated in the peel compared to the flesh of the orange. Additionally, the bitterness can also be influenced by the cooking process and the amount of sugar added to the marmalade. Some people enjoy the bitter notes in orange marmalade as it adds complexity to the flavor profile. **

Store-bought orange juice may taste bitter due to a few reasons. One reason is that the juice may have been sitting on the shelf for a long time, causing it to oxidize and develop a bitter taste. Additionally, some store-bought orange juices may contain added preservatives or artificial flavors that can contribute to a bitter taste. Finally, the juice may have been made from oranges that are not fully ripe, leading to a more bitter flavor. **

Freshly squeezed orange juice becomes bitter over time due to a process called oxidation. When the juice is exposed to air, the oxygen in the air reacts with the compounds in the juice, causing them to break down and produce bitter-tasting compounds. Additionally, enzymes in the juice can also contribute to the development of bitterness as they continue to work on the juice even after it has been squeezed. To slow down this process, it is best to store freshly squeezed orange juice in an airtight container in the refrigerator. **
