Seven elements, namely, arsenic, lead, cadmium, copper, zinc, iron and manganese were determined in 31 samples of Serbian plum brandies by applying atomic spectrometry techniques. Flame atomic absorption spectrometry was used for quantification of copper, iron, zinc, manganese, lead and cadmium; and hydride generation atomic spectrometry absorption for arsenic quantification. Measured concentrations of heavy metals and arsenic was assessed according to the Serbian regulations, official regulations of some other countries and in respect of microelements content in other similar distilled alcoholic beverages. Amounts of microelements in maximal recommended daily and weekly intake of plum brandy were determined. The influence of production (home made and industrial), type of wooden barrel (oak and mulberry), and duration of ageing process on the content of Zn, Cu, Fe and Mn in plum brandies, as well as coefficient of correlation between Cu content and pH value were also studied.

There is proliferation of alcoholic beverages flavoured with herbal-extracts perceived to have medicinal values. Information on the phytochemical and heavy metal contents of these products is scarce. This study assessed the phytochemical properties and heavy metal contents of herbal-extract flavoured alcoholic beverages in major motor parks in Ibadan, Nigeria. The phytochemical properties of the beverages were determined in triplicate using standard methods while the heavy metal contents were assessed using atomic absorption spectrophotometry. Data were analyzed using descriptive statistics and means were compared using ANOVA at p<0.05. The pH range of the beverages was 3.28-6.57 and the alcohol content was 34.0-51.5%. Detected major phytochemicals and concentration ranges were phytic acid (0.72-2.37 mg/g), alkaloids (0.42-4.11 mg/g), flavonoids (0.22-3.64 mg rutin equivalents/g), total phenols (1.13-3.66 mg gallic acid equivalents/g), anthraquinones ((0.74-1.93 mg/g) and triterpenoids (0.74-1.93 mg/g). The phytochemical contents were within the acceptable limits while the heavy metals were: Pb (2.13-4.70 mg/L), Cd (0.06-0.07 mg/L), Co (0.12-0.23 mg/L), Zn (0.14-0.40 mg/L) and Fe (0.72-4.22 mg/L); all except Pb and Cd were within permissible limits. The herbal-extract flavoured alcoholic beverages contain beneficial phytochemicals and traces of heavy metals. Safety awareness of these products for improved consumers’ health would be of public health importance.

This study examined the roles of income, prices and household demography in household demand for non-alcoholic beverages (NABs) in two cities – Abeokuta and Ibadan in Southwest Nigeria. The study was based on primary data obtained from a cross-section of 407 households (211 from Abeokuta and 198 from Ibadan) drawn by multistage sampling technique across six Local Government Areas (LGAs) and 60 National Population Commission (NPC) enumeration areas (EAs). A structured questionnaire was used to collect data on households NABs expenditure, income, prices and other relevant socio-economic variables. The data were analysed within the framework of a linear approximation of an Almost Ideal Demand System. The study found that an average household, consisting of five (5) members, expended an average N5, 235.89 per month on NABs (approximately US$34.21 at N153.06/US$1 exchange rate in 2010). The bulk (67%) of the NABs expenditures were devoted to purchase of dairy products (36%) and cocoa-based products used in preparing chocolate drinks (31%). The estimated income elasticity of demand for the six categories of NABs studied were positive while all the own price elasticity of demand were negative. Demand for dairy products and cocoa based drinks were found to be price elastic, while those of carbonated drinks, malt drinks, fruit juice and other NABs were price inelastic. Increase in education of the household heads was found to be associated with significant increase in the budget shares of dairy products (p<0.01) and fruit juice (p<0.10), but a significant reduction in budget shares of cocoa-based products (p<0.05), carbonated drinks (p<0. 01) and malt drinks (p<0.05). The study concludes that policies aimed at promoting increased demand and healthy choices of NABS must pay some attention to raising real income and increasing level of education among the citizenry. Profitability of business enterprises involved in dairies and cocoa-based products would also be better enhanced if the firms adopt cost saving strategies as against price hikes in a bid to enhance performance.

Abstract Background Malnutrition is a frequent problem in inflammatory bowel disease (IBD) due to the increase in caloric consumption because of the pathology itself and due to the reduced intake. This low intake is mainly caused by the symptoms and the anorexia associated with the disease, but it is more and more common for patients to adopt elimination diets. Our aim was to investigate the general ideas about nutrition in patients with IBD, as well as to determine whether they consider that health professionals value the nutritional aspect. Methods Inclusion of patients with an established diagnosis of IBD followed-up in the unit of the Hospital Universitario La Paz, using an anonymised survey for the researcher and for the attending physician. Results A total of 118 patients were included, of which 56% (65 patients) were women. The mean age of the patients was 48.84 years (SD 14.2). All patients had a previous diagnosis of IBD: 51.7% (61 patients) ulcerative colitis (UC), 45% (53 patients) Crohn’s disease (CD) and 3.3% (4 patients) undetermined colitis. 55.6% (64 patients) believed that nutrition influenced the course of their IBD. The patients who answered yes were on average younger (44.5 vs. 53.9 years), these differences being statistically significant (p = 0.0003). Only 22 of the 64 patients (34.4%) believed that it was caused by a specific food or food group and the most frequent answer was food rich in fats, dairy products, alcohol or spices. 52.1% of the sample (61 patients) had eliminated some food from the diet since the diagnosis of IBD. The most noteworthy was the avoiding of dairy products (37%), fibre in 28% (most of them reducing the intake of fruits and vegetables), alcoholic drinks (17%) and carbonated drinks (11.5%). No statistically significant differences were found in the elimination of food from the diet according to age, sex or type of IBD. No differences were observed in the elimination of dairy products, carbonated drinks or alcoholic beverages depending on the type of IBD, being more frequent the elimination of fibre in patients with UC (7/10 patients) than in CD. Regarding the role of their attending physician, 77.5% (86 patients) thought that nutrition was important for their doctor and/or nurse dedicated to IBD, although only 52.6% (61 patients) believed they had received enough information for their pathology. Conclusion The health professionals dedicated to IBD should increase our efforts to properly inform patients about nutritional aspects, since in our experience more than a half of patients avoid one or more foods (without scientific evidence to support it). Furthermore, only 52.6% consider that they receive sufficient information regarding this matter.

The modern beverage industry works in a dynamic and very competitive market, with increasing sales but decreasing profit margins. Projected global sales for carbonated soft beverages are expected to reach $195 billion by 2014. Carbonated drinks are differentiated from other drinks by their “fizziness” (that comes from the dissolved carbon dioxide), which creates a “tingling” sensation in the mouth, and provides a unique taste sensation. They can be divided in non-alcoholic and alcoholic beverages. The non-alcoholic drinks are known as soft drinks and can be fruit based (orange, lemon and lime), cola type drinks (Pepsi, Coca cola), or others such as new energy drinks (like Red Bull), while alcoholic carbonated drinks include beer, cider, sparkling wines, etc. In order to maintain the flavour and the other quality attributes at the appropriate consumer level of appreciation, it is necessary to perform several quality control (QC) analyses. The most usual quality control ...

The structure of the air-water interface forms a boundary layer that involves biological ,chemical geological and physical processes in its formation. Freshwater and sea surface microlayers form at the air-water interface and include a diverse assemblage of organic matter, detritus, microorganisms, plankton and heavy metals. The sampling of microlayers and the examination of components is presently a significant area of study because of the input of anthropogenic materials and their accumulation at the air-water interface. The neustonic organisms present in this environment may be sensitive to the toxic components of these inputs. Hardy reports that over 20 different methods have been developed for sampling of microlayers, primarily for bulk chemical analysis. We report here the examination of microlayer films for the documentation of structure and composition.Baier and Gucinski reported the use of Langmuir-Blogett films obtained on germanium prisms for infrared spectroscopic analysis (IR-ATR) of components. The sampling of microlayers has been done by collecting fi1ms on glass plates and teflon drums, We found that microlayers could be collected on 11 mm glass cover slips by pulling a Langmuir-Blogett film from a surface microlayer. Comparative collections were made on methylcel1ulose filter pads. The films could be air-dried or preserved in Lugol's Iodine Several slicks or surface films were sampled in September, 1987 in Chesapeake Bay, Maryland and in August, 1988 in Sequim Bay, Washington, For glass coverslips the films were air-dried, mounted on SEM pegs, ringed with colloidal silver, and sputter coated with Au-Pd, The Langmuir-Blogett film technique maintained the structure of the microlayer intact for examination, SEM observation and EDS analysis were then used to determine organisms and relative concentrations of heavy metals, using a Link AN 10000 EDS system with an ISI SS40 SEM unit. Typical heavy microlayer films are shown in Figure 3.
