This study aimed to evaluate the effect of rootstocks on fruit sugars, organic acids, and carotenoids. The contents of sugars and organic acids in fruits were determined by HPLC. Total acidity (TA), total soluble solids (TSS), and pH value of the juice were also evaluated. Total carotenoids and chlorophylls contents were measured using a spectrophotometer. The content of ethylene in fruits was ...

Juice prepared from lemon (Eureka), mandarin (Kinnow) and orange (Orlando) fruits cultivated in Saudi Arabia were analyzed for different physico-chemical properties, total phenolics, ascorbic acid and antiradical activities. Juices from lemon, mandarin and orange 8.97, 16.1 and 11.78% total soluble solids; 5.73, 1.37 and 1.69% titrable acidity; 79.21, 91.18 and 107.37 mg GAE/100mL total phenoli...

IN T RODUC T ION QuEChERS methodology is commonly used for sample preparation of fruits and fruit juices, prior to LC/MS or other analytical chromatography. Recently, a nonregistered fungicide residue, carbendazim, was detected in orange juice purchased at a local market. This juice was produced from orange juice concentrate imported into the USA. In this application note, we discuss sample pre...

The prevention of spoilage by Alicyclobacillus acidoterrestris is a current challenge for fruit juice and beverage industries worldwide due to the bacterium's acidothermophilic growth capability, heat resistance, and spoilage potential. This study examined the effect of storage temperature on A. acidoterrestris growth in hot-filled orange juice. The evolution of the A. acidoterrestris populatio...

“While our findings suggest that people who consume large amounts of whole grapefruit or orange juice may be at increased risk for melanoma, we need much more research before any concrete recommendations can be made,” said lead study author Shaowei Wu, PhD, a postdoctoral research fellow at the Department of Dermatology, the Warren Alpert Medical School of Brown University in Providence, Rhode ...

This paper examines how consolidation in the marketing system affects prices for orange juice. We isolated the pricing behavior of brand marketers, wholesalers, and retailers by observing the retail prices for specific orange juice products, including leading national brands and private label brands, in 54 U.S. markets over a 1-year period. The data provided little compelling evidence that cons...

Citrus sinensis (orange) by-products represent one of the most abundant citric residues from orange juice industrial production, and are a promising source health-promoting compounds like terpenes.

T hegenerally accepted definition of a functional food or beverage is a product that has an ‘‘added physiological benefit above and beyond its naturally occurring benefits.’’ So for instance, orange juice with nothing added is a regular beverage, whereas orange juice with added plant sterols is a functional beverage because the plant sterols are added for a physiological benefit, to help reduce...

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...

Pomegranate juice is in high demand due to its well documented health benefits. Studies based on a significant body of scientific research conducted on authentic pomegranate juice have established that pomegranate juice has superior antioxidant activity compared to other popular fruit juices such as grape, orange and apple1,2,3. These superior health benefits have led to a meteoric rise in the ...
