Changes in physicochemical traits, peel colour, and juice attributes of four blood orange cultivars (‘Moro’, ‘Tarocco’, ‘Sanguinello’, ‘Sanguine’) were evaluated during 180 days at 2 5 °C plus 20 for shelf life. ‘Tarocco’ had the lowest weight firmness losses both temperatures storage. Titratable acidity (TA) was higher than °C, with ‘Sanguinello’ showing highest TA, respectively. Juice content...

OBJECTIVE The aim of this study was to compare color stability and surface topography of three different feldspathic porcelains both qualitatively and quantitatively after exposure to routinely consumed beverages over different time periods using a Spectrophotometer, Stereomicroscope and Surface roughness tester, respectively. MATERIALS AND METHODS A total of 90 plastic discs were casted to o...

The capacity of developing countries for citrus fruits exportation is limited by the lack of adequate storage techniques. In studying this problem citrus sinensis Osbeck was treated with, a locally developed bemul-wax, calcium chloride dip, and a combination of the two. The treated fruits were assessed during four month low temperature storage (7.0 ± 3.0 o C; 9094% RH.) for their biochemical an...

This study was aimed at establishing the possibility of producing an acceptable wine from the mixture of pawpaw juice and coconut milk in the following proportions; 90:10, 80:20, 70:30, 60:40 and 50:50 respectively. The process of washing, peeling, extraction of juice, amelioration, clarification, sulphiting, pitching, fermentation, clarification, bottling, pasteurization and ageing were applie...

This study was conducted to evaluate the combined effects of blanching and sonication on carrot juice quality. Carrots were blanched at 100 °C for 4 min in normal and acidified water. Juice was extracted and sonicated at 15 °C for 2 min keeping pulse duration 5 s on and 5 s off (70% amplitude level and 20 kHz frequency). No significant effect of blanching and sonication was observed on Brix, pH...

A study was conducted to determine the effects of packaging materials, seasonality, storage temperature and time on physiochemical and antioxidant properties of roselle-mango juice blends. Roselle extract (20%, 40%, 60%, and 80%) was mixed with mango juice and stored in glass and plastic bottles at 4°C and 28°C. Total soluble solids, pH, titratable acidity, reducing sugar, color, vitamin C, tot...

background & aim: erosion has been defined as the irreversible loss of dental hard tissue by a chemical process not involving bacteria. dental erosion is an important cause of tooth tissue loss in both children and adults. acids of intrinsic and extrinsic origin (gastric juice and acidic foodstaffs, beverages) are thought to be the main etiologic factors for dental erosion. the reported inciden...

Quality characteristics of tomato fruit will be affected by a number preand post harvest factors. In this study, the effect of maturity stage on post harvest quality characteristics of tomato was investigated. Tomato fruits of the same farmers‟ variety were harvested at mature-green, medium ripe and full-ripe stages. After harvesting, tomato samples were sliced and homogenized in blender for pr...

OBJECTIVE To determine the dental hazards associated with sports supplement drinks by investigating the chemicophysical properties of eight brands of sports drinks. METHODS The pH and titratable acidity against 0.1 M NaOH was measured. Calcium, phosphate, and fluoride concentrations and viscosities of Carbolode, Gatorade, High Five, Isostar, Lucozade Sport Lemon, Lucozade Sport Orange, Maxim,...
