OBJECTIVES Plasma concentrations are frequently used for therapeutic drug monitoring of antiretroviral drugs. Dried blood spot sampling offers a patient-friendly and easy alternative to plasma sampling. However, dried blood spot concentrations are not necessarily equal to plasma concentrations and therefore the objective of this work was to establish the relationship between nevirapine and efav...

Cold pressed peel oil was added to high quality 50°Brix commercial orange concentrate and foam-mat dried, or diluted to single strength juice and freeze-dried using different platen temperatures. Amounts of peel oil ranged from 0.026% to 0.106% for samples to be foam-mat dried, and from 0.011% to 0.109% for freeze drying. For foam-mat drying, previously de veloped standard commercial conditions...

In this study, microcrystalline cellulose (MCC) was isolated from walnut and apricot shells (WS AS) as agricultural wastes in order to use it reinforcement polymer composites. The extracted by alkaline treatment bleached peroxide an environmentally friendly treatment, called (WC) (AC). chemical composition of the samples set according Technical Association Pulp Paper Industry (TAPP). After trea...

Background: Dried fruit is one of the main sources of sulphur dioxide (SO2) exposure. The major goal of the current study was to determine SO2 concentration in some widely consumed dried fruits in Hamadan, Iran. In addition, an estimate of sulphite intake was made through the aforementioned dried fruit. Methods: Totally, 126 dried fruit samples were randomly collected from local market in Hama...

The drying of pears allows their conservation due principally to the inhibition of microbial growth, making the dried pear a safe food for consumers. The knowledge of microbial flora, as well as some biochemical factors, is very important for ensuring the consumers health. In this study samples of pears of the variety S. Bartolomeu were dried under different systems: traditional open air sun dr...

Systematic study of how different drying methods, namely hot-air drying, vacuum-drying, and freeze-drying, affect color, browning index, degree of rehydration, water solubility, and vitamin C content is critical for utilizing pine needle powders (PNP) as a novel ingredient in functional foods. Samples prepared by vacuum-drying showed a significantly higher L*-value, whereas higher a*- and b*-va...
