A great interest has recently been focused on lycopene and β-carotene, because of their antioxidant action in the organism. Red-flesh watermelon is one of the main sources of lycopene as the most abundant carotenoid. The use of near-infrared spectroscopy (NIRS) in post-harvesting has permitted us to rapidly quantify lycopene, β-carotene, and total soluble solids (TSS) on single intact fruits. W...

Little data is available in the scientific literature on postharvest changes taking place in Syzygium aqueum fruits, an increasingly popular fruit in the Asian region. In this study the postharvest physico-chemical and mechanical properties, namely, fruit color, weight loss, pulp firmness, total soluble solids, pH and titratable acidity were determined during the postharvest storage period unde...

This paper presents a comparison of U.S. Geological Survey stream monitoring station measurements of total suspended solids (TSS) yield and stream bank erosion monitoring data with a suspended solids model developed by Brown and Caldwell and used by the Gwinnett County, Georgia Department of Water Resources (DWR) to inform its watershed improvement efforts. A comparison between modeled and aver...

Physiologically mature, uniform fruits were thoroughly washed and dipped in aqueous solution of T0 (Untreated fruits), T1 (Boric acid at 200 ppm), T2 300 T3 (NAA 100 T4 T5 (Salicylic 300ppm), T6 400ppm) for five minutes. Fruits placed plastic trays stored ambient storage conditions 12 days. The readings observed after 4rd, 8th 12th Physiological weight loss decreased with storage, further treat...

Investigations have demonstrated that ratio of sugars to organic acids affects the particular taste of citrus fruit and carotenoids are essential for prevent of the disease.  It seems that some rootstocks enhance the ripening of fruits and stimulatethe biosynthesis of sugars and carotenoids. The aim of this study was to evaluate the effect of rootstocks on sugars, organic acids andcarotenoids o...

Fusariosis (Fusarium guttiforme) is the most destructive disease of pineapple crop in Brazil. The aim this study was to evaluate reaction an isolate genotypes selected for crownless fruit weight (CFW) and total soluble solids (TSS). A 1,125 ('BRS Imperial'×'Pérola') were evaluated. Selection greatest CFW TSS performed during sexual cycle. inoculated on slip-type plantlets using immersion techni...

Cactus pear (Opuntia ficus-indica (L.) Mill.) fruit from ‘Orito’ cultivar were stored at 2 °C and 90% RH for 28 days plus three 20 (shelf life, SL). This research analysed the changes in quality parameters (weight loss, firmness, color, titratable acidity, total soluble solids), ethylene production, respiration rate, antioxidant activity bioactive compounds (total phenols carotenoids) of cactus...

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 ...

A circular gravity-phase separator using coalescing medium with cross flow was developed to remove oil and suspended solids from wastewaters. Coalescence medium in the form of inclined plates promotes rising of oil droplets through coalescence and settling of solid particles through coagulation. It exhibits 22.67% higher removal of total suspended solids (TSS) compared to separators without coa...
