Brief Summary

Commercially available fruit juices are obtained after applying industrial technologies to preserve and extend the shelf-life by inactivation of microorganism and enzymes. These are traditional thermal treatment (eg. pasteurization, sterilization) that causes losses of nutritional and bioactive compounds, changes physicochemical properties (colour, flavor and texture) and can modify their bioavailabilities. Thus, the traditional thermal processing is being replaced by less intense thermal technologies (e.g. low-temperature pasteurization / refrigerated storage) and non-thermal treatments such as the high-pressure processing (HPP) and the pulsed electric fields (PEF) as an alternative to enhace food safety and shelf-life without compromising organoleptic qualities (retain the flavour, color healthiness of fresh foods) and keeping their health-promoting capacity. The beneficial health effect derived from the orange juice intake is partly related to the bioavailability of their bioactive compounds. The aim of this study was to assess the effect of the intake of freshly squeezed orange juice (Citrus sinensis L.) and processed orange juice elaborated with different treatments (low pasteurization / refrigerated storage, high-pressure processing, pulsed electric fields) on the main serum carotenoid concentrations in a cross-over study in apparently healthy subjects using multiple dosis.

Outcome Measures

Primary Outcomes (1)

  • Assessment of the effect of dairy intake of orange juice elaborated with four different procedures on the serum carotenoid concentrations of healthy adults.

    Assessment of the effect of dairy intake of orange juice elaborated with low temperature pasterurization (LP), high-pressure processing (HPP), pulsed electric fields (PEF) and freshly squeezd (FS) on the serum carotenoid concentrations of healthy adults.

    6 months

Study Arms (4)

Freshly squeezed orange juice (FS)

ACTIVE COMPARATOR

Subjects were enrolled to consume 500 mL of orange juice/day during three consecutive 14 days periods separated by 1 - 1.5 month washouts. The orange juice assayed was freshly squeezed (FS). Six subjects consumed FS-orange juice.

Other: Orange juice

Commercially available low pasteurized orange juice (LP)

ACTIVE COMPARATOR

Subjects were enrolled to consume 500 mL of orange juice/day during three consecutive 14 days periods separated by 1 - 1.5 month washouts. The orange juices assayed was commercially available low pasteurized juice (LP). All participants consumed the LP orange juices.

Other: Orange juice

High-pressure processed orange juice(HPP)

ACTIVE COMPARATOR

Subjects were enrolled to consume 500 mL of orange juice/day during three consecutive 14 days periods separated by 1 - 1.5 month washouts. The orange juices assayed was high-pressure processed (HPP). All participants consumed the HPP orange juices.

Other: Orange juice

Pulsed electric fields treated orange juice (PEF)

ACTIVE COMPARATOR

Subjects were enrolled to consume 500 mL of orange juice/day during three consecutive 14 days periods separated by 1 - 1.5 month washouts. The orange juices assayed was those treated with pulsed electric fields (PEF). Six participants consumed the PEF-orange juice.

Other: Orange juice

Interventions

Subjects were enrolled to consume 500 mL of orange juice/day during three consecutive 14 days periods separated by 1 - 1.5 month washouts. The orange juices assayed were: freshly squeezed (FS), commercially available low pasteurized juice (LP) and juices treated by high-pressure processing (HPP) and by pulsed electric fields (PEF). All participants consumed the LP and the HPP orange juices. Six subjects consumed PEF-orange juice and other six consumed the FS-orange juice.
