Scientists have discovered a new method of extracting apple juice that may further increase its efficacy.
In a study published in the International Journal of Food Research, the new method was found to increase the amount of polyphenols in the juice by up to four times that of ordinary apple juice.
Polyphenols are antioxidants that occur naturally in fruits and cocoa. These compounds have many benefits for heart and brain health and may even protect against disease.
Researchers say that the amount of these compounds in the juice can be increased using a process called a ‘spiral filter press’. The juicing process removes oxygen, which reduces the chances of the ingredients spoiling.
Past research has shown that polyphenols (flavonol-3-ols) can help improve blood pressure, cholesterol levels, and blood sugar.
Study co-researcher Stephen Dussling said the loss of ingredients is usually due to the presence of oxygen, which rapidly degrades components of apple juice such as flavonols or vitamin C.
According to experts, this happens when we extract apple juice at home or buy this juice from the store.
