Methane potential of sterilized solid slaughterhouse wastes.
2012
Abstract The aim of the current study was to determine chemical composition and methane potential of Category 2 and 3 solid slaughterhouse wastes rendering products (SSHWRP) viz. melt, decanter sludge, meat and bone meal (MBM), technical fat and flotation sludge from wastewater treatment. Chemical analyses showed that SSHWRP were high in protein and lipids with total solids (TS) content of 96–99%. Methane yields of the SSHWRP were between 390 and 978 m3 CH4/t volatile solids (VS)added. Based on batch experiments, anaerobic digestion of SSHWRP from the dry rendering process could recover 4.6 times more primary energy than the energy required for the rendering process. Estonia has technologic…
Leberfunktion von Ratten nach chronischer VerfÜtterung von90Sr
1966
Nach chronischer VerfUtterung von90Sr in Mengen von 140 und 350 pC/g Ca konnte bei Ratten eine leichte Beeintrachtigung der Ausscheidungsleistung der Leber im Bromsulfonphthalein-Test nachgewiesen werden. Diese Wirkung verstarkte sich mit Erhohung der zugefUhrten90Sr-Menge und mit Verlangerung der FUtterungsdauer. Da der Anstieg der Farbstoffretentionswerte in diesen Versuchen nur ein geringes Ausmas erreichte, wird somit wahrscheinlich gemacht, das durch eine sehr lang dauernde FUtterung von90Sr mit den hier gewahlten Dosierungen keine Leberschadigung ausgelost wird.
What determines a positive attitude towards natural food products? An expectancy theory approach.
2021
Natural food products are becoming increasingly popular worldwide due to their health and environmental benefits. However, these products' increasing anecdotal popularity has not translated into their widespread adoption; in fact, demand for natural food products remains confined to a relatively small segment of consumers. Despite this, little is known about the facilitators and inhibitors of favourable attitude of consumers towards these products. Recognising this gap, our study employed the theoretical lens of expectancy theory to investigate these factors. Through an extensive review of the pro-environmental consumption literature, we identified four facilitating and inhibiting factors: …
Capillary Liquid Chromatography for the Determination of Terpenes in Botanical Dietary Supplements
2021
Dietary supplements of botanical origin are increasingly consumed due to their content of plant constituents with potential benefits on health and wellness. Among those constituents, terpenes are gaining attention because of their diverse biological activities (anti-inflammatory, antibacterial, geroprotective, and others). While most of the existing analytical methods have focused on establishing the terpenic fingerprint of some plants, typically by gas chromatography, methods capable of quantifying representative terpenes in herbal preparations and dietary supplements with combined high sensitivity and precision, simplicity, and high throughput are still necessary. In this study, we have e…
Could halophilic archaea improve the traditional salted anchovies (Engraulis encrasicholus L.) safety and quality?
2010
Aims: The positive influence of two selected extremely halophilic archaea strains in the production of salted anchovies (Engraulis encrasicolus, L., 1758) was highlighted. Methods and Results: Anchovies produced with salt artificially contaminated with halophiles exhibited lower loads of staphylococci, Enterobacteriaceae and lactic acid bacteria, and a reduced content of histamine as well as an improved organoleptic acceptance. Conclusions: The findings of this survey are expected to enhance the safety of salted anchovies, with regard to the histamine formation during ripening, and to improve the sensory attributes of this product. Significance and Impact of the Study: This study repres…
Study on the application of an interspecific competition model for the prediction of microflora behaviour during the fermentation process of S. Angel…
2009
The use of predictive microbiology models able to evaluate bacterial behaviour as a function of environmental conditions and, at the same time, of natural microflora competition was considered by several authors with different approaches. Some authors modelled bacterial competition as a function of metabolic product with particular regard to lactic acid and modelled interspecific bacterial competition introducing a term into a conventional primary predictive model, which gives account for the interaction between two populations, so that they inhibit each other to the same extent that they inhibit their own growth.
Development of new non-dairy beverages from Mediterranean fruit juices fermented with water kefir microorganisms
2016
The aim of this work was to explore the use of several Mediterranean fruit juices as fermentable substrates to develop new non-dairy fermented beverages. Microbiological, chemical and sensory features of kefir-like beverages obtained after the fermentation of juices extracted from fruits cultivated in Sicily (southern Italy) with water kefir microorganisms were investigated. Results indicated that both lactic acid bacteria and yeasts were able to develop in the fruit juices tested, but the highest levels were registered with prickly pear fruit juice. All fruit juices underwent a lactic fermentation, since a lactic acid content was detected in the resulting kefir-like beverages. Except kiwif…
Polymorphisms in ABC transporter genes and concentrations of mercury in newborns - Evidence from two Mediterranean birth cohorts
2014
Background: The genetic background may influence methylmercury (MeHg) metabolism and neurotoxicity. ATP binding cassette (ABC) transporters actively transport various xenobiotics across biological membranes. Objective: To investigate the role of ABC polymorphisms as modifiers of prenatal exposure to MeHg. Methods: The study population consisted of participants (n = 1651) in two birth cohorts, one in Italy and Greece (PHIME) and the other in Spain (INMA). Women were recruited during pregnancy in Italy and Spain, and during the perinatal period in Greece. Total mercury concentrations were measured in cord blood samples by atomic absorption spectrometry. Maternal fish intake during pregnancy w…
La soluzione italiana alla crisi delle filiere agroalimentari: il decreto legge 19 marzo 2019, n. 27
2019
L’Autore affronta il tema della regolazione della filiera agroalimentare e dei tentativi di porre rimedio ai fallimenti del mercato . Analizzando i recenti interventi normativi in risposta alle gravi crisi del comparto lattiero-caseario, emergono difficoltà e incertezze del legislatore e del governo italiano nell’affrontare queste criticità, che sono legate all’assenza di un’adeguata regolazione di tipo contrattuale . Inadeguatezza che può essere affrontata e risolta puntando su di un mutamento di approccio e considerando che le relazioni contrattuali di filiera necessitano di interventi proporzionati, più efficaci ed efficienti, in grado di esaltare i momenti di autonomia contrattuale disc…
Analysis of the Aggregate Financial Behaviour of Customers Using the Transtheoretical Model of Change
2014
Abstract The authors addressed the problem of aggregate financial behaviour of customers by using the transtheoretical model of change. Aggregate financial behaviour of customers was studied by analyzing payment cards, private pension savings and mortgage loans. The transheoretical model of change was chosen as a theoretical framework for the analysis. Conclusions are based on results of regression analysis of empirical evidence of customers’ financial behaviour relation to the given products during the time period 2001-2013 in Latvia and further logical inferences by authors, which are consistent with the chosen theoretical framework of the transtheoretical model of change
