Food and Nutrition Sciences-Is commercially bottled 100% fruit juice with the “no sugar added” label really no sugar?

The bottled fruit juice is often labeled “no sugar added”,but does it really not contain higher sugar content than extracted juice of fresh fruit？

A scientist published an article <Comparison of Sugar Content in Bottled 100% Fruit Juice versus Extracted Juiceof Fresh Fruit > in the Scientific Research Publishing.This artical made a study on this topic. The fruit juices that were tested included apple, grapefruit, orange, pineapple, pomegranate, red grape and white grape. All bottled juices and fresh fruits were purchased in Toledo, Ohio, USA during the winter of 2012. The fresh fruits were juiced and three samples were tested for sugar concentration using a Brix refractometer. The same testing protocol was also applied to the bottled 100% fruit juice. Application of the Mann-Whitney test on the experimental data demonstrated no statistically significant difference (p > 0.05).

Finally, the results suggested that the sugar content in the commercially bottled 100% fruit juice with the “no sugar added” label is an accurate representation of sugar content in the freshly-extracted juice of the corresponding fruit.
