Supercharge your juice experience
Scientists in Germany have discovered a new ‘super’ apple juice, with the potential to improve heart health by boosting blood flow.
Researchers at Hochschule Geisenheim University have found a way to maximise polyphenols in apple juice by using a novel squeezing method called a spiral filter press, which actively takes out oxygen by vacuum-driven pressing. What’s more, they ensure oxygen is excluded from all other processing steps, therefore reducing nutrient deterioration.
According to the researchers, a 280ml serving of the new apple juice would be enough to provide 100% of the ideal intake for a key group of polyphenols, called flavan-3-ols, which help promote a healthy blood flow.
“Apple juice is already a source of polyphenol compounds, but you would need to drink several glasses to reach the levels recommended by scientists for heart health effects,” explained Professor Ralf Schweiggert, lead author of the paper. “The new juicing method that we’ve investigated takes the polyphenol content to a new level by minimizing the nutrient losses we typically see during juicing.”
