Tag: Blackcurrant jam

According to nutrition data, fresh blackcurrants are recognized as a good source of potassium, containing approximately 322 mg per 100 grams. However, when considering if blackcurrant jam is high in potassium, it's crucial to understand how the fruit's nutritional profile changes during the preservation process.

An impressive 100 grams of fresh blackcurrants contains over 180 mg of vitamin C, far more than oranges. So, is there any vitamin C in blackcurrant jam after it's cooked? The answer is yes, though much of the original content is lost during the heat-intensive jamming process, with the final amount depending on cooking methods and storage.
