“…One major difference between the juice and fruit is the higher pectin (fibre) content of whole fruit, which is largely removed during manufacture to produce juice. Nevertheless, when expressed as a typical serving, the difference in fibre between the edible part of a whole orange (80 g) and a small glass of orange juice (150 mL) is approximately 1 g [8], equating to just 3% of the EU/UK Dietary Reference Value of 30 g. Sources of data [8][9][10][11][12].…”

Dietary guidelines often deal with 100% fruit juice (FJ) inconsistently because it represents a source of free sugars. However, FJ also provides bioavailable micronutrients and plant bioactives at levels similar to those found in whole fruits. The present review weighs up the evidence from high-quality studies investigating a potential health harm for FJ against evidence from studies which indicate a potential health benefit. The findings reveal that FJ consumption, at moderate intakes consistent with the dietary guidelines for the US and some European countries (75–224 mL daily), does not increase the risk of obesity, type 2 diabetes, cardiovascular disease or poor glycaemic control. In contrast, regular consumption of FJ—even up to 500 mL per day in short-to-medium-term studies—appears to confer a health benefit in terms of vascular function and reduced blood pressure. Emerging evidence for cognitive health benefits requires further investigation in human trials. Observational studies report associations between FJ and nutrient adequacy and suggest that FJ consumption is associated with reduced risk of stroke. In conclusion, FJ appears to offer more benefit than risk and there appears to be no justification for discouraging FJ within a balanced diet for children and adults.

“…Las pectinas son uno de los constituyentes principales de la pared celular de frutos y vegetales (Camejo et al, 2006). Se ha reportado que los frutos de los cítricos presentan el más alto contenido de pectina en comparación con otros frutos (Ywassaki y Canniatti-Brazaca, 2011). En este estudio, se evaluó la extracción de pectina a partir de desechos de lima Persa injertada en diferentes portainjertos.…”

This study describes the 1H‐NMR‐based metabolomics profiling of juices from citrus fruits harvested in the state of Veracruz, México. The hydrophilic profile of commercial lemons (Agrio and Persian), tangerines (Fremont and Mónica), oranges (Valencia and Washington Navel), and grapefruits (Red Ruby and Rio Red) was determined. According to our results, 35 metabolites were identified in the 1H‐NMR profiling. The statistical differences obtained by PCA and OPLS‐DA revealed that specific amino acids, sugars, and organic acids were differential metabolites in the species and cultivars studied. High endogenous levels of sucrose (10–190 mM), α‐glucose, β‐glucose (α‐ and β‐isomers, 40–205 mm), and fructose (36–170 mm) were detected in the juices of grapefruits, oranges, and tangerines, whereas citric acid (40–530 mm) was the principal organic acid in the juices of lemons. To calculate the specific amounts of metabolites from these species and their cultivars, the results were finely analyzed using the qNMR method. According to these calculations, Valencia oranges had the highest concentration of ascorbic acid (>2 mm). The described 1H‐NMR method is highly reproducible, inexpensive, and highly robust in comparison to other analytical methods used to determine the hydrophilic profile of citrus juices.
