The effects of different treatment methods on the stability and antioxidant capacity of the bioactive phenolic compounds of litchi pericarps were investigated. Fresh litchi pericarps were open air-dried, steam-blanched for 3 min in combination with hot air oven drying at 60 and 80 °C, and unblanched pericarps were dried in a hot air oven at 40, 60, 70 and 80 °C until equilibrium weight was reac...

High-resolution gas-phase infrared spectroscopy of buckminsterfullerene (C 60 ) was attempted near 8.5 μmusing cavity ring-down spectroscopy. Solid C 60 was heated in a high-temperature (∼950K) oven and cooled using an argon supersonic expansion generated from a 12.7mm × 150 μm slit.The expected S/N ratio is ∼140 for vibrationally cold C 60 , but no absorption signal has been observed, presumab...

In this study, two processes (fermentation and drying) were conducted on Clicanthus Nutans Lindau, which is well-known for its antioxidant activities. The aim of this research is to investigate the effects of these processes towards the Total Phenolic Content (TPC), antioxidant activity and the crude yield of the leaves. For the fermentation process, the fermentation time is varied for 6, 12, 2...

Allyl sulfur compounds are the major active constituents found in crushed garlic. Research has revealed that garlic and its lipid- or water-soluble components have many pharmacologic properties; however, studies also demonstrate that heating has a negative influence on these beneficial effects. We recently conducted several studies to investigate the influence of microwave or oven heating on th...

Introduction: Recent increase of endocrine disorders may be correlated to the increased exposure to electromagnetic fields from various instruments. Radiation leakage from microwave oven may be harmful for users. Ladies have the highest levels of contact with microwave ovens. This study was carried out to evaluate the effect of radiation leakage from microwave oven on body weight, cortisol a...

Abstract Porous cellulose nanofibril (CNF) foam was prepared by stabilizing bubbles with CNF and a surfactant then drying the stabilized wet in convection oven. The consistency of carboxymethylated (CMCNF) addition amount were controlled effects these factors on dry properties investigated. An adequate (0.02–0.04 wt%) CMCNF higher than 0.5 wt% yielded foams excellent stability. When dried at 60...

BACKGROUND The use of pomegranate peel is highly associated with its rich phenolic concentration. Series of drying methods are recommended since bioactive compounds are highly sensitive to thermal degradation. The study was conducted to evaluate the effects of drying on the bioactive compounds, antioxidant as well as antibacterial and antityrosinase activities of pomegranate peel. METHODS Dri...

Three experiments were conducted to evaluate nutrient content and DM determination methods of dry milling byproducts. In Exp. 1, nutrient composition was determined for wet distillers grains plus solubles (WDGS) and modified distillers grains plus solubles (MDGS) from 6 ethanol plants with 10 samples collected per day, across 5 d, and sampling was repeated over 4 separate months. Mean compositi...
