The present work aimed both at improvement and extension of a previously developed process for the production of cactus pear juice. The total yield was increased by 10% through processing whole instead of peeled fruits and by further optimisation of pulp enzymation. As an alternative to HTST pasteurisation, cross-flow microfiltration was applied for non-thermal cactus pear juice preservation. J...

The grape juice industry has shifted almost entirely from the old method of storing juice in 5-gallon carboys to cool storage in tanks at 22 to 28 F (-5.5 to -2.2 C). Excess tartrates are precipitated during storage. When juice was stored in carboys, the carboys wNere filled at processing temperature, and either spray-cooled or allowed to cool slowly at the cellar storage temperature. For the m...

Control of the raw material has considerable influence on final wine quality. The objective of this work was to develop a sensor capable of assessing grape juice quality in the cellar. Sensor response was compared with conventional chemical analysis using multivariate data techniques. The aroma sensor array is composed of 14 metal oxide sensors (MOS) gas transducers plus a temperature and a rel...

Children are encouraged to eat a specific amount of fruits and vegetables to optimize health. The purpose of this study was to assess whether consumption of a variety of fruits and vegetables, respectively, was associated with a greater diet quality among preschool-aged children. Analyses were performed using a cross-sectional, nationally representative sample of US children. Dietary intakes fr...

the turbidity of sour orange juice after juice extraction affects on quality, shelf-life and concentration of juice. therefore, juice clarification is an important operation in the fruit processing industry. the goal of this study was evaluating the effect of membrane operation parameters including pressure (120-220 kpa) and temperature (25-35 ºc) on the permeate flux and hydraulic resistance o...

introduction: conventional technology of sugar production from sugar beet roots consists of the next subsequent steps: sugar beet slicing, thermal denaturation of the sliced beet roots followed by diffusion in hot water at 70–75 _c, purification of extracted juice by lime, concentration of purified juice and crystallization. the diffusion process is one of the most important steps that effect o...

BACKGROUND Cranberries (particularly in the form of cranberry juice) have been used widely for several decades for the prevention and treatment of urinary tract infections (UTIs). The aim of this review is to assess the effectiveness of cranberries in preventing such infections. OBJECTIVES To assess the effectiveness of cranberry juice and other cranberry products in preventing UTIs in suscep...

Juices from 2 cultivars of muscadine grapes (Vitis rotundifolia Michx.), 'Noble' (dark-skinned) and 'Carlos' (bronze-skinned), were mixed with juices of 'Concord' and 'Niagara' grapes, cranberry or apple. 'Noble' juice, combined with 'Concord' juice, resulted in the highest quality among the dark mixtures prepared. Also, the mixtures retained most color and flavor during a 12 month storage peri...
