in recent years, the scientists have focused on nanotecnology and its applications as the most important fields of research and development. the use of nanoparticles offers many advantages, due to their unique size and physical properties. magnetic iron oxide nanoparticles have been used in many fields, because of their unique properties such as large specific surface area and convenient separa...

OBJECTIVE To assess the nutritional and dietetic profile of freshman Nutrition undergraduate students, and its association with stages of changes (Transtheoretical Model) for fruit and vegetable intake. METHODS Demographic (age and gender), anthropometric (body mass index and waist circumference) and nutritional (pattern of fruit and vegetable intake) data were obtained. The Transtheoretical ...

There is a dearth of information on the percentage of waste during preparation of food by the average woman. Such figures would be of value in dietary surveys, since some food tables give analyses for raw foods only 'as purchased', so that edible portions on dietary records must often be converted to 'as purchased' amounts before conversion to calories and nutrients. During two long-term dietar...

Electron microscopy is a recognized standard tool for nanomaterial characterization, and recommended by the European Food Safety Authority for the size measurement of nanomaterials in food. Despite this, little data have been published assessing the reliability of the method, especially for size measurement of nanomaterials characterized by a broad size distribution and/or added to food matrice...

background and objectives: recently, due to the interest of healthy lifestyle demand for research on novel methods of increasing the shelf-life of food products without the necessity of using preservatives has extended rapidly in the world. ability of nanoemulsions to improve global food quality has attracted great attention in food preservation. this is as a result of a number of attributes pe...

New challenges to the safety of the food supply require new strategies for evaluating and managing food safety risks. Changes in pathogens, food preparation, distribution, and consumption, and population immunity have the potential to adversely affect human health. Risk assessment offers a framework for predicting the impact of changes and trends on the provision of safe food. Risk assessment m...

INTRODUCTION: STUDYING FOOD This position paper seeks to uncover and understand a range of everyday behaviours associated with food shopping, preparation, consumption and waste as a precursor to design. How food is purchased, prepared, consumed and its waste disposed of is of growing interest for those concerned with sustainability and ‘carbon footprint’ [2, 3]. This topic provides interesting ...

Introduction: Norovirus is the leading cause of acute gastroenteritis and foodborne disease in the United States, causing an estimated one in 15 U.S. residents to become ill each year as well as 56,000–71,000 hospitalizations and 570–800 deaths, predominantly among young children and the elderly. Whereas noroviruses often spread through person-to-person contact, foodborne transmission can cause...

Improvement of food worker hand washing practices is critical to the reduction of foodborne illness and is dependent upon a clear understanding of current hand washing practices. To that end, this study collected detailed observational data on food worker hand washing practices. Food workers (n = 321) were observed preparing food, and data were recorded on specific work activities for which han...
