This study was carried out to evaluate the quality of the three edible tissues (muscles, hepatopancreas and gonads) of the male and female Chinese mitten crab (Eriocheir sinensis) in natural harvest season, based on total volatile base nitrogen test (TVBN) and biogenic amines analysis at intervals time of 3 h extended for 24 h during 30 °C storage (a mean ambient temperature in harvest season)....

The aim of the present work was to study the changes of the content of biogenic amines during winemaking and maturation processes of wines made from Vitis vinifera cv Sauvignon grapes from Slavonia region (vintage 2008). Biogenic amines were quantified using a reversed-phase high performance liquid chromatography (HPLC) with fluorescence detection after precolumn derivatization with o-phthalald...

Petrovská klobása is a traditional dry fermented sausage produced in the Autonomous Province of Vojvodina. Formation of nine biogenic amines was determined in three sausage groups produced from hot deboned (A1) and cold meat (B1, B3) during drying and ripening in traditional room (A1, B1) and in industrial ripening chamber (B3). Dansyl chloride derived amines were analysed by high-performance l...

[1] Aircraft observations of carbon monoxide (CO) from the ICARTT campaign over the eastern United States in summer 2004 (July 1–August 15), interpreted with a global 3-D model of tropospheric chemistry (GEOS-Chem), show that the national anthropogenic emission inventory from the U.S. Environmental Protection Agency (93 Tg CO y ) is too high by 60% in summer. Our best estimate of the CO anthrop...

AIMS To evaluate the ability of grapevine ecosystem fungi to degrade histamine, tyramine and putrescine in synthetic medium and in wines. METHODS AND RESULTS Grapevine and vineyard soil fungi were isolated from four locations of Spain and were subsequently identified by PCR. A total of 44 fungi were evaluated for in vitro amine degradation in a microfermentation system. Amine degradation by f...

1 Aims: To evaluate the ability of grapevine ecosystem fungi to degrade histamine, tyramine 2 and putrescine in synthetic medium and in wines. 3 Methods and Results: Grapevine and vineyard soil fungi were isolated from four locations of 4 Spain and were subsequently identified by PCR. A total of 44 fungi were evaluated for in 5 vitro amine degradation in a microfermentation system. Amine degrad...

Biogenic amines may reach concentrations of public health concern in some cheeses. To minimize biogenic amine buildup in raw milk cheese, high-pressure treatments of 400 or 600 MPa for 5 min were applied on days 21 and 35 of ripening. On day 60, counts of lactic acid bacteria, enterococci, and lactobacilli were 1 to 2 log units lower in cheeses treated at 400 MPa and 4 to 6 log units lower in c...

We apply a full year of continuous atmospheric acetone measurements from the University of Minnesota tall tower Trace Gas Observatory (KCMP tall tower; 244 m a.g.l.), with a 0.5× 0.667 GEOS-Chem nested grid simulation to develop quantitative new constraints on seasonal acetone sources over North America. Biogenic acetone emissions in the model are computed based on the MEGANv2.1 inventory. An i...

Biogenic polyamines, such as putrescine, spermidine, and spermine are small organic polycations involved in numerous diverse biological processes. These compounds play an important role in nucleic acid function due to their binding to DNA and RNA. It has been shown that biogenic polyamines cause DNA condensation and aggregation similar to that of inorganic cobalt(III)hexamine cation, which has ...

Biogenic emissions and secondary organic aerosols (SOA) are strongly dependent on climatic conditions. To understand the SOA levels and their sensitivity to future climate change in the United States (U.S.), we present amodelingworkwith the consideration of SOA formation from the oxidation of biogenic emissions with atmospheric oxidants (e.g., OH, O3, and NO3). The model simulation for the pres...
