This study aims to determine the drying rate constant of coconut chips using an oven. Coconut is carried out at temperatures 50 ° C, 60 C and 70 C. Drying has been conducted initial water content 40-50% wb until it reached ± 10% wb. The change moisture was measured every 15 minutes, measurement determined by thermogravimetric method. Newton's model used in determining observation constant. Furt...

Micropropagation of banana (Musa paradisiaca Linn.) var Grand naine was carried out with media sterilized by microwave radiation. Microwave oven was effectively used to sterilize the media for in vitro shoot-multiplication of banana against autoclave. Sterilization of media in microwave oven was successfully achieved at 900W/200 ml media (4 min). In vitro shoot-multiplication was higher in the ...

An individual kernel moisture meter and an individual kernel oven drying procedure were used to quantify the kernel-to-kernel moisture content (MC) variation in equilibrated rough rice samples varying in MC from 9 to 37%, w.b. Average, bulk sample MCs were also determined using an oven drying method. No difference (p < 0.05) was found in the average MCs measured by the meter at three weeks or t...

This study investigates effects from different drying methods (vacuum oven dried vs. freeze dried) on the rheological, functional and structural properties of chicken skin gelatin compared to bovine gelatin. Vacuum oven dried chicken skin samples showed a higher gelatin yield (12.86%) than freeze-dried samples (9.25%). The latter showed a higher melting temperature (32.64oC) and superior foamin...

In this paper, an integrated coke dry quenching combined gasification system using coke oven gas and steam to quench the incandescent coke is proposed. The distinct advantages of the system include energy conservation, pollution reduction, coke quality improvement and full use of resources. Based on the minimization of the Gibbs free energy, the flow rate and composition of the syngas are predi...

The demand for broadband wireless communication in home and office has been increasing exponentially; thus, the need for reliable and effective communication is very crucial. Both theoretical and experimental investigations have clearly shown that electromagnetic radiation from external sources such as microwave oven (MWO) has detrimental impact on the wireless medium and the media content. The...

We conducted a repeated-measures cohort study of coke oven workers to evaluate the relationships between the traditional exposure biomarker, urinary 1-hydroxypyrene (1-OHP), and a series of biomarkers, including urinary 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodG), N7-methylguanine (N7-MeG), acute toxicity, and mutagenicity. A total of eight spot urine samples were collected from each high-exp...

Purpose: To determine the effect of three methods of drying, viz, sun, oven and microwave, on Stevia rebaudiana Bertoni leaf’s nutritional composition. Methods: Fresh Stevia rebaudian bertoni leaves were dried separately by sun, oven and microwave. The chemical composition was determined by Association of Official Agricultural Chemists (AOAC) method. Tannin content was measured by titrimetric m...
