Flavor quality of Liriopis tuber tea that was made using a steaming process was studied by measuring changes in headspace volatile compounds. Headspace volatile compounds of the prepared samples were isolated, separated and identified by the combined system of purge & trap, automatic thermal desorber, gas chromatography, and mass selective detector. As steaming frequencies were increased, the a...

A three factor three level central composite design was adopted to determine interactive effects of meat level (55-65%), steaming time (12-18 minutes) and drying time (7-9 hrs) on pH, moisture, protein content, fat content and other quality characteristics (Hardness, adhesiveness, total colour change and overall acceptability) of extruded chicken noodles. Moisture, protein, fat level and total ...

The most efficient steaming conditions below 200 degrees C for extracting antioxidants from used tea leaves and their reaction behavior during the steaming treatment were investigated. The antioxidative activity of the steamed extracts increased with increasing steaming temperature, and the yield of the ethyl acetate extract fraction from each steamed extract showing the greatest antioxidative ...

Molluscs are consumed by many communities and believed to use as a reliable drug. This research was aimed to study the changes of proxymate composition, cholesterol, and fatty acid composition due to processing methods and to determine the best method resulting in the best quality product. The experiment consisted of preparation and characterization of raw materials, determination of salt conce...

BACKGROUND Panax ginseng Meyer is cultivated because of its medicinal effects on the immune system, blood pressure, and cancer. Major ginsenosides in fresh ginseng are converted to minor ginsenosides by structural changes such as hydrolysis and dehydration. The transformed ginsenosides are generally more bioavailable and bioactive than the primary ginsenosides. Therefore, in this study, hydroth...

CO2 emissions from maritime transport operations represent a substantial part of the total greenhouse gas emission. Vessels are designed with better energy efficiency. Minimizing CO2 emission in maritime operations plays an important role in supply chain decarbonisation. This paper reviews the initiatives on slow steaming operations towards the reduction of carbon emission. It investigates the ...

BACKGROUND This study was carried out to investigate the effect of the steaming process on chemical constituents, free radical scavenging activity, and antiproliferative effect of Vietnamese ginseng. METHODS Samples of powdered Vietnamese ginseng were steamed at 120°C for various times and their extracts were subjected to chemical and biological studies. RESULTS Upon steaming, contents of p...

The Eucalyptus grandis logs temperatures were determined and correlated with the board's cracks during steaming. Thermocouples were inserted in the logs center, registering their temperatures during steaming at 90°C. The logs were sawed and the board's cracks measured. It was concluded that: (1) the logistic S-shaped curve explains the logs temperature variation; (2) the logs with diameter of 2...

Gadung (Dioscorea hispida Dennst.) has been considered as one of staple foods in Indonesia. However, its high cyanides content has limited its utilisation for commercial food production. This work is aimed to investigate the removal of cyanides content from gadung tuber chips through two consecutive treatments, i.e. leaching and steaming and to propose mathematics model for the leaching process...

BACKGROUND Panax notoginseng is a potential source of anticancer compounds. This study aims to investigate the effects of steaming on the chemical profile of P. notoginseng and the anti-proliferative effects of P. notoginseng on liver cancer cells. METHODS Samples of powdered raw P. notoginseng roots were steamed for various durations. Extracts of the raw and steamed samples were subjected to...
