Regulatory Issues And Functional Health Claims For Bioactive Dairy Compounds, P. Roupas, P. G. Williams, C. Margetts
Regulatory Issues And Functional Health Claims For Bioactive Dairy Compounds, P. Roupas, P. G. Williams, C. Margetts
Peter Williams
Dairy foods and ingredients have a natural advantage over new/novel foods, from a regulatory viewpoint, because they are generally considered as “traditional” foods, that is, there is a long history of human consumption. However, the regulatory landscape on adding bioactive ingredients, whether from dairy streams or from non-dairy sources, into dairy foods is rapidly evolving, and the dairy industry will need to be aware of potential regulatory challenges, within the countries they wish to market their products.

Lifecourse Socioeconomic Trajectories And C-Reactive Protein Levels In Young Adults: Findings From A Brazilian Birth Cohort, Aydin Nazmi, I. O. Oliveira, Bernardo L. Horta, D. P. Gigante, Cesar G, Victora
Aydin Nazmi
Socioeconomic factors are associated with cardiovascular disease. C-reactive protein (CRP) is increasingly implicated as a candidate linking conventional risk factors and atherosclerosis. The impact of early- and later-life socioeconomic status (SES) on CRP levels has not been widely investigated and a handful of studies from high-income countries are inconsistent. We set out to examine the associations between lifecourse socioeconomic indicators (family income at birth, maternal education, family income at age 23 and own education) on CRP levels in young adults belonging to the 1982 Pelotas (Brazil) Birth Cohort Study (n = 5914). Early-life SES showed significant and graded associations with …

Professor Emmanuel Ohene Afoakwa
Studied were conducted to evaluate the combined effects of spontaneous fermentation and Amylase Rich Flours (ARF) on some nutritive value, functional and viscoelastic properties of cowpea-fortified nixtamalized maize. A 2x3x3 factorial design, with fermentation medium, fermentation time and ARF level was performed. The blends were fermented for the specific times and analysed for their titratable acidity, pH, water absorption capacity, viscoelastic properties, texture, protein and mineral content. Fermentation and ARF addition influenced titratable acidity, pH, water absorption, viscoelastic properties and texture of the cowpea-fortified nixtamalized maize. Addition of ARF decreased the viscoelastic properties, texture and pH of all the blends …

Leonard Piché
Excessive consumption of sweetened beverages by children and youth has become an issue of great concern among health professionals and health policy makers in the U.S. and Canada. Over-consumption of sweetened beverages can have negative effects on children's nutrient profile and may increase their risk of obesity. Reducing children's sweetened beverage consumption offers an opportunity to decrease unnecessary energy intake and prevent excess weight gain.

Paying developing countries for carbon sequestration is seen as a vital component of climate change mitigation. If appropriately designed, these payments can also transfer income to poor villagers, which can aid both the long-term sustainability of the carbon sequestered, as well as meeting the goal of poverty reduction. However, to encourage the participation of small-scale producers, a CDM forest project must offer sufficient incentives with minimal costs to participants. Both incentives and costs are embedded in property rights, social capital and contractual rules. In this paper, we ask what factors affect participation in the world’s first CDM project, established in …

Childhood Poverty And Abdominal Obesity In Adulthood: A Systematic Review, David González, Aydin Nazmi, Cesar G. Victoria
Aydin Nazmi
Adverse socioeconomic conditions in childhood can have lasting effects on health, but evidence is lacking from prospective studies concerning the effects of early poverty on abdominal obesity in adulthood. Cross-sectional studies in adults from middle and high-income countries show that current socioeconomic status is inversely related to obesity in women, but the pattern in men is not consistent. A systematic review was undertaken to assess the influence of early socioeconomic status on waist circumference, hip circumference, and waist-hip ratio in adulthood. Thirteen relevant articles were located (five cross-sectional and eight cohort), including only one from a middle-income country and the …
A Rapid Direct Solvent Extraction Method For The Extraction Of 2-Dodecylcyclobutanone From Irradiated Ground Beef Patties Using Acetonitrile., Amit Kumar
Amit Kumar, DVM, MS, PhD
The amount of irradiated beef in the U.S. market is growing, and a reliable, rapid method is needed to detect irradiated beef and quantify the irradiation dose. The official analytical method (BS EN 1785 2003) that has been adopted by the European Union is time consuming. The objective of this study was to develop a rapid method for the analysis of 2-dodecylcyclobutanone (2-DCB) in irradiated beef. A 5 g sample of commercially irradiated ground beef patty (90/10) was extracted with n-hexane using a Soxhlet apparatus or with acetonitrile via direct solvent extraction. The Soxhlet hexane extract was evaporated to dryness, …

Viscoelastic Properties And Pasting Characteristics Of Fermented Maize: Influence Of The Addition Of Malted Cereals, Dr. Emmanuel Ohene Afoakwa (Phd), Randy Adjonu, Justice Asomaning
Professor Emmanuel Ohene Afoakwa
Investigations were conducted on the viscoelastic properties and pasting characteristics of fermented maize with malted cereals and their suitability for infant feeding. A 3x3x2 factorial experimental design with malting time, cereal malt concentration and cereal type was used. Maize, millet, and sorghum malts were added to fermented maize to reducing its bulk density. Samples were analysed for their viscoelastic properties and pasting characteristics using Brabender Viscoamylograph. Sorghum malt in comparison to millet and maize malts was not effective in terms of lowering the hot and cold paste viscosities of the fermented maize. Maize and millet malts liquefied the dough considerably …

Acidification And Starch Behaviour During Co-Fermentation Of Cassava And Soybean Into Gari., Dr. Emmanuel Ohene Afoakwa (Phd), Edem John Kongor, George Annor, Randy Adjonu
Professor Emmanuel Ohene Afoakwa
Changes in acidification and starch behaviour were investigated during co-fermentation of cassava and soybean into gari, an African fermented product. Non-volatile acidity, pH and starch content were evaluated using standard analytical methods. Starch breakdown and pasting characteristics were also analysed using Brabender Viscoamylograph. Fermentation caused significant variations in the pH, non-volatile acidity and starch concentration. The pH decreased with concomitant increases in non-volatile acidity during co-fermentation of the cassava dough. Soy-fortification upto 20% caused only minimal effects on the pH, titratable acidity and starch content during the fermentation period. Starch content decreased from 69.8%-60.4% within the 48 h fermentation time …

Response surface methodology was used to optimize the processing conditions in the preparation of cowpea tempeh. The independent factors studied were boiling time (varying from 5 to 30 min), incubation time (varying from 12 to 48 h) and incubation temperatures (varying from 25 to 50°C), whereas the dependent factors were protein content, protein solubility, pH, titratable acidity and total color difference (using L, a* and b*). Regression models were generated and adequacy was tested with regression coefficients (R2) and the lack-of-fit tests. Optimum processing conditions were determined by method of superimposition. There was a strong and significant influence (P < 0.01) of the quadratic effect of the incubation time on the protein content of the cowpea tempeh, with similar significance (P < 0.01) noted in protein solubility with increasing boiling time. The optimum processing conditions observed for the preparation of cowpea tempeh were boiling time of about 20 min, incubation time of about 28 h and incubation temperature of about 37°C.
