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...

this paper reports on the use of artificial neural networks (ann) and partial least squareregression (pls) combined with nir spectroscopy (900-1700 nm) to design calibration models for thedetermination of sugar content in sugar beet. in this study a total of 80 samples were used as the calibration set,whereas 40 samples were used for prediction. three pre-processing methods, including multiplic...

Raspberry leaf blotch emaravirus (RLBV) has become established in many Serbian raspberry orchards as the most prevalent virus of raspberries country. The aim this study was to evaluate impact RLBV on red ?Willamette? variety. A trial conducted four located Western Serbia. Fruits from RLBVinfected and uninfected canes were analyzed for fruit size (fruit length, width, height, shape, weight), sol...

This study was undertaken to evaluate the efficiency of a liquid-solids separation process and microwave pretreatment, as well as anaerobic biodegradability of microwave pretreated dairy manure. Liquid-solids separation of raw dairy manure resulted in solid and liquid fractions having different properties, with the solid fractions richer in total and volatile solids content and liquid fractions...

The results of experiments on municipal wastewater primary effluent are presented for a pilot-scale submerged membrane bioreactor (SMBR). The SMBR pilot plant employed an ultrafiltration membrane with a nominal pore size of 0.035 microm and was operated at a constant membrane flux of 30 L/m(2)h. The mixed liquor suspended solids (MLSS) concentration was maintained at 8+/-2 g/L and steady-state ...

This work evaluates the effect of temperature and soluble solids on degradation rate phenolic compounds, antioxidant activity extracts from Bixa orellana L. leaves. The temperatures were studied in range typical food processes (70-90 °C) storage (−20-37 °C). results showed that thermal compounds follows first-order kinetics, which depends temperature, amount solids, pH. loss also kinetics. Unde...

The effects of mandarin scions on peel components and juice quality parameters were investigated in this study. Peel flavor components were extracted by using cold-press and eluted by using n-hexane. Then all analyzed by GC-FID and GC-MS. Total soluble solids, total acids, pH value, ascorbic acid as well as density and ash were determined in juice obtained from mandarin scions. Twenty-seven, Tw...

The objective of this study was to investigate the production microbial cellulase by using Aspergillus oryzae and its application in treatment coffee. producing method used for microbe medium submerged fermentation with malt extract medium. determining activity spectrophotometry at wavelength 540 nm 3,5-DNS reagent measure reducing sugar (the product enzymatic reaction). Then, applied on green ...

background: an essential oil is a liquid that is generally distilled from the leaves, stems, flowers or other elements of a plant. objective: cumin (cuminum cyminum l.) essential oil (ceo) was analyzed to determine oil component. antifungal effect of ceo was determined by in vitro technique. in second stage, effect of different concentrations of ceo by pdm on postharvest life of strawberry (fra...
