Effects of formulation and baking process on acrylamide formation in Kolompeh, a traditional cookie in Iran

Thermal treatments and recipes are two critical aspects for the formation of acrylamide at ordinary household cooking conditions and industrial level. Kolompeh is a traditional Iranian cookie, and the aim of this study was to monitor acrylamide formation in four different recipes: traditional sugary Kolompeh (TSK), traditional simple Kolompeh (TSIK), industrial sugary Kolompeh (ISK), and industrial simple Kolompeh (ISIK). Along with the measurement of reducing sugars, moisture, and pH, acrylamide was quantified by gas chromatography mass spectrometry (GC-MS). Results indicated that acrylamide content was 1758, 1048, 888, and 560 μg/kg for TSK, TSIK, ISK, and ISIK, respectively, revealing that the kind of thermal treatment in combination with higher concentrations of reducing sugars were the major driver for acrylamide formation. In particular, acrylamide concentration in TSIK direct heating was 1.87 times higher than industrial indirect heating treatment, highlighting that domestic preparation of Kolompeh required a specific attention as a source of potential toxic molecule formation

Impact of rapeseed press-cake on Maillard reaction in a cookie model system

Rapeseed press-cake (RPC) is a byproduct of rapeseed oil production, rich in proteins and fiber. The aim of this study was to investigate the impact of cold pressed RPC, RPC fiber isolate and RPC alkaline extract on the formation of acrylamide and 5-hydroxymethylfufural (HMF) in cookies. Both compounds were influenced by the ingredients: the addition of RPC led to a significant dose-dependent increase of HMF in the cookies and to an increase of acrylamide up to 66.9%. On the contrary, acrylamide concentration was reduced down to 39.6% in presence of the alkaline extract and down to 4.4% in the presence of the fiber extract. The Michael addition of free amino acids to acrylamide was further investigated by high-resolution mass spectrometry (HRMS) revealing that cysteine was the preferred nucleophile for acrylamide elimination

How Saving the Cookies for Santa Could Save Our Children

Environmental factors and high sugar lunches represent a few proposed causes of the childhood obesity epidemic. Consequences of this epidemic are not limited to physical illnesses in children, but also psychological ones. The solution to this issue is more complex than a low carbohydrate diet or increased physical activity. Children need to be raised in an environment which fosters healthy lifestyle habits year-round

Food safety

Illness induced by unsafe food is a problem of great public health significance. This study relates exclusively to the occurrence of chemical agents which will result in food unsafe for human consumption since the matter of food safety is of paramount importance in the mission and operation of the manned spacecraft program of the National Aeronautics and Space Administration

Master\u27s Project: Tending to Joy

If we dare to hope for the thriving of humans and all of life, then joy must hold a solid place in our imagination. The purpose of this project was to breathe joy into my own life and into the world around me. Following a literature review, I carried out three mini-projects – creating crowd-sourced collages out of what brings people joy, sending daily text messages with quotes about joy, and providing cookies to groups working on social change efforts. The projects succeeded in spreading delight, raising spirits, and inspiring reflection. The journey towards cultivating joy in my own life was substantially messier and remains completely unresolved. I conclude this project not yet able but still aspiring to fully say “yes” to life

Acrylamide: Increased concentrations in homemade food and first evidence of its variable absorption from food, variable metabolism and placental and breast milk transfer in humans

We have developed a liquid chromatography/mass spectrometry (LC-MS/MS) assay to determine acrylamide in various body fluids. The assay also allows the reliable quantitation of acrylamide in food. In a total of 11 healthy male and female subjects, we were able to show that acrylamide from food given to humans is in fact absorbed from the gut. The half-lives determined in two male subjects were 2.2 and 7 h. Acrylamide was found in human breast milk and penetrated the human placenta (n = 3). The variability of acrylamide concentrations found in this investigation is most likely caused by variable intersubject bioavailability and metabolism. This may be an important indication that the assessment of the risk from acrylamide for the individual may be very difficult without knowing the concentrations of acrylamide in the body. This should be considered in the design of any risk assessment study or post hoc analysis of earlier studies. At this time, we suggest that pregnant women and breast-feeding mothers avoid acrylamide-containing food. Copyright (C) 2002 S. Karger AG, Basel

Immigrant Entrepreneurs Creating Jobs and Strengthening the U.S. Economy in Growing Industries

The focus of this report evolved from a 2010 conference at Babson College on "Immigrant Entrepreneurship in Massachusetts" sponsored by The Immigrant Learning Center, Inc. (ILC) from which two key ideas emerged. One is that there is an "immigrant entrepreneurship ecology" that includes immigrant neighborhood storefront businesses; immigrant high-tech and health science entrepreneurs; immigrant non-tech growth businesses; and immigrant transnational businesses. A second idea was that these growing, non-tech industries (including transportation, food and building services) have not attracted much attention. Interestingly, these sectors can be crucial to the expansion of the green economy. Within this context, The ILC decided to look at these three sectors in Massachusetts as well as in New York and Pennsylvania.Moreover, the report dramatically illustrates how immigrant entrepreneurs look for niches in underserved markets. For example, vans and other alternatives to mass transit serve unmet transportation needs in urban areas. Food intended to be a "taste of home" for compatriots in local restaurants and grocery stores becomes popular and influences the eating habits of other Americans. Workers who enter industries like landscaping or cleaning because they don't require much English gain experience and see opportunities to start their own companies. Businesses like these add value to American life by expanding the economy rather than taking away from native businesses

The status of Fusarium mycotoxins in Sub-Saharan Africa : a review of emerging trends and post-harvest mitigation strategies towards food control

Fusarium fungi are common plant pathogens causing several plant diseases. The presence of these molds in plants exposes crops to toxic secondary metabolites called Fusarium mycotoxins. The most studied Fusarium mycotoxins include fumonisins, zearalenone, and trichothecenes. Studies have highlighted the economic impact of mycotoxins produced by Fusarium. These arrays of toxins have been implicated as the causal agents of wide varieties of toxic health effects in humans and animals ranging from acute to chronic. Global surveillance of Fusarium mycotoxins has recorded significant progress in its control; however, little attention has been paid to Fusarium mycotoxins in sub-Saharan Africa, thus translating to limited occurrence data. In addition, legislative regulation is virtually non-existent. The emergence of modified Fusarium mycotoxins, which may contribute to additional toxic effects, worsens an already precarious situation. This review highlights the status of Fusarium mycotoxins in sub-Saharan Africa, the possible food processing mitigation strategies, as well as future perspectives

Causation and epidemiologic evidence: insights from “toxic cases” in the US and Italy

Proving causation between exposure to toxic substances and long latency disease is often a challenging task. This is clearly showed by the U.S. toxic tort litigation, as well as by the Italian experience of criminal investigation and trials for occupational and pollution-related diseases. After a summary of the main hurdles surrounding the proof of causation in \u201ctoxic cases\u201d, this post addresses the question of whether the most readily available type of scientific evidence \u2013 i.e. epidemiologic studies \u2013 could be used in a different, more effective way than has been done so far

Assessing the Distracting Viewing Environment for Televised Sports and its Relationship to Advertising Recall

The viewing of televised sports, like other television viewing situations, is often accompanied by many audience distractions. These distractions, which are particularly acute in the viewing of televised sports, include group viewing, wagering, and food and beverage consumption. All these activities may influence the impact of advertising placed within sports programs, which totals almost $3 billion annually. This study uses reports of the activities listed above by individuals while viewing pro football\u27s Super Bowl and gathered through a day-after national coincidental sample, to assess the relationship of these distractions to advertising recall. Regression results show that the consumption of certain foods and beverages, as well as conditions common to viewing televised sports, are related to recall of commercials. Growing use of database marketing, linking product purchases with viewing habits, broadens the implications of these findings for future media planning
