Background and Objectives: Recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. Factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...

Alkalizing beverages are highly effective in preventing the recurrence of calcium oxalate (Ox), uric acid and cystine lithiasis. The aim of the present study was to evaluate the influence of grapefruit-juice and apple-juice consumption on the excretion of urinary variables and the risk of crystallization in comparison with orange juice. All investigations were carried out on nine healthy female...

OBJECTIVE Our objective was to determine whether Seville orange juice produces a grapefruit juice-like interaction with felodipine and whether bergamottin, 6',7'-dihydroxybergamottin, or other furocoumarins are involved. METHODS In a randomized three-way crossover design, 10 volunteers received a felodipine 10-mg extended-release tablet with 240 mL of Seville orange juice, dilute grapefruit j...

OBJECTIVE To measure iron absorption in children from meals containing apple juice or orange juice so as to determine if iron absorption will be greater with orange juice because of its higher ascorbic acid content than apple juice, a noncitrus fruit juice that US children reportedly prefer. DESIGN On 2 successive days, children consumed identical meals that included apple juice on one day an...

the conditions for the refinement of clarified sugarcane juice, including temperature (50o, 60o and 70oc) and pressure (0, 0.5, 1 and 1.5 bars) by micro-filtration membrane technology were investigated. the raw sugarcane juice was initially pre-filtrated with lime and then the juice obtained (clarified juice) processed using a ceramic micro-filter mem-brane (0.2 micrometer). the characteristics...

BACKGROUND 6',7'-Dihydroxybergamottin is a furanocoumarin that inhibits CYP3A4 and is found in grapefruit juice and Seville orange juice. Grapefruit juice increases the oral bioavailability of many CYP3A4 substrates, including cyclosporine (INN, ciclosporin), but intestinal P-glycoprotein may be a more important determinant of cyclosporine availability. OBJECTIVES To evaluate the contribution...

INTRODUCTION Green juice is popularly known for introducing antioxidants, improving intestinal function and reducing weight gain. OBJECTIVES In the present study we determine the antioxidant effect of green juice comparing it with orange juice. METHODS Rats were divided into three experimental groups and submitted to supplementation for 15 days: the (GJ) group received green juice, the (OJ)...

Prickly pear (Opuntia spp) fruit has received renewed interest since it contains a betalain pigment that has an attractive purple colour for the production of juice. Prickly pear juice was prepared by homogenizing the fruit and treating the pulp with 48 g of pectinase from Aspergillus niger. Titratable acidity was determined by diluting 10 ml prickly pear juice with 90 ml deionized water and ti...

This paper presents a review of cactus-pear juice production. Its technological characteristics are considered, as well as the main difficulties in obtaining high-quality juice. Acidity, pigments, aroma, and other components play an important role in the cactus pear juice processing. Betalain and chlorophyll are present in purple and green cactus pear juices, and heat treatment of the juices af...

There is a great interest in food components that possess possible health-protecting properties, as is the case with flavonoids. Previous research showed that conventional apple juice processing resulted in juices poor in flavonoids and with a low antioxidant activity. This paper shows that it is possible to improve flavonoid content in juice and its antioxidant activity by applying an alcoholi...
