Interfacial adsorption and shear flow properties of gum arabic-sodium caseinate mixtures
Publication date: 2011 Source:Procedia Food Science, Volume 1 Author(s): Bibiana Bonilla-Reyna , María G. Sosa-Herrera , Laura P. Martínez-Padilla This work discusses rheological and physicochemical properties of sodium caseinate and gum arabic, in aqueous media (25°C). All the systems showed low viscosity values and Newtonian behaviour in the shear rate range studied. From particle size distribution, a limited thermodynamic compatibility was observed since hydrocolloids mixtures showed particles size between the values from the systems alone. Interfacial tension measurements at equilibrium at the air-water inter...

Morphology and fluorescence properties of dye-entrapped silica nanoparticles
Publication date: 2011 Source:Procedia Food Science, Volume 1 Author(s): Namsoo Kim , Sun-Mi Oh , Chong-Tai Kim , Chul-Jin Kim , Yong-Jin Cho Dye-entrapped silica nanoparticles can be used to label biological components in immunosensing since they are bright and photostable, less prone to stochastic blinking with sustained imaging, biologically inert and thus basically non-toxic, and compatible with aqueous system due to hydrophilic surface. Therefore, the objective of this study was to produce dye-entrapped silica nanoparticles and to determine the morphological and spectral characteristics of these particles. Si...

Implementation of a novel tool to quantify dough microstructure
Publication date: 2011 Source:Procedia Food Science, Volume 1 Author(s): Mario Jekle , Thomas Becker A method was developed to quantify the microstructure of wheat dough proteins assessed by a confocal laser scanning microscope (CLSM) in combination with an image processing and analyzing tool. A variation of the water addition especially showed high significant (p<0.01) linear correlations with the branching index (r=-0.92). This branching index exhibited high significant correlation coefficients with the rheological measures complex shear modulus (r=0.88), creep compliance (r=-0.71) and relative elastic part ...

US, Canadian, Australian, and New Zealand Datasets Seen through Foreign Eyes
Publication date: 2013 Source:Procedia Food Science, Volume 2 Author(s): Jayne Ireland , Anders Møller Food composition databases (FCDBs) are published with such different formats and levels of documentation, that it is often difficult to compare values or import data using standard procedure. Data from four online FCDBs – USA, Canada, Australia, and New Zealand – were downloaded and transformed according to EuroFIR specifications for presenting data and metadata. Despite their different levels of documentation, the data in these 4 FCDBs can be compared and interchanged using the standardized EuroFIR eSearch pla...

Nutrient Databases: Critical Tools for Policy Development
Publication date: 2013 Source:Procedia Food Science, Volume 2 Author(s): Jessica Leighton , Kathleen M. Koehler , Claudine Kavanaugh , Kasey Heintz Nutrient databases provide critical tools for developing effective government policies to promote healthy diets and a nutritionally healthy food supply. This paper highlights the role of nutrient databases in various phases of policy development referencing folic acid as a historical illustration and providing more recent examples of trans fat and sodium reduction in the food supply. Limitations of both public and proprietary nutrient databases are considered and improv...

Awareness and use of MyPlate Guidelines in Making Food Choices
This study aims to 1) assess consumers’ awareness of the replacement of MyPyramid with MyPlate, and 2) determine whether MyPlate influenced people's dietary choices 4 months after the MyPlate symbol's release. Methods Fifty-one male and female participants, ages 18-34 years, with high school, associate's and bachelor's degree diplomas, were selected by convenience sampling. Participants manually completed an 11-question survey using yes/no or degree of liking rating. The relationship between participants’ backgrounds, familiarity with MyPlate and MyPyramid guidelines, and the likelihood of use and influence on food s...

SuperTracker Incorporates Food Composition Data into Innovative Online Consumer Tool
Publication date: 2013 Source:Procedia Food Science, Volume 2 Author(s): Patricia Britten The SuperTracker online dietary and physical activity assessment tool is a major outreach effort to encourage behavior change and help implement the 2010 Dietary Guidelines. It provides a user-friendly but powerful interface to help individuals enter food intake, compare it to nutrient goals and the USDA Food Patterns, and track intake over time. At its core, the SuperTracker relies on a food database adapted from ARS's Food and Nutrient Database for Dietary Studies (FNDDS) and MyPyramid Equivalents Database (MPED). Modifications...

Federal Monitoring Activities Related to Food and Nutrition: How do they Compare?
Publication date: 2013 Source:Procedia Food Science, Volume 2 Author(s): Jaspreet K.C. Ahuja , WenYen Juan , Katie Egan , Jean Buzby , Paula Trumbo , Alanna Moshfegh , Joanne Holden Several nutrition monitoring related activities are carried out by the federal government in the United States. These include the What We Eat in America, National Health and Nutrition Examination Survey (WWEIA, NHANES), the Total Diet Study (TDS), and the Nutrient Availability Data (NA). The intent, purpose, and methodology of the activities, and their inter-relationships were examined. Mean intakes of selected nutrients common to th...

The USDA-Agricultural Research Service (ARS) Program in Dietary Surveillance and Food Composition: State of the Program and Future Directions
Publication date: 2013 Source:Procedia Food Science, Volume 2 Author(s): John W. Finley , David M. Klurfeld The USDA-Agricultural Research Service (ARS) supplies nutritional surveillance data that are used by government and the private sector. Data are supplied by two programs; one program partners with the Department of Health and Human Services to conduct the What We Eat in America portion of the National Health And Nutrition Examination Survey (WWEIA-NHANES); the other program compiles analytical data concerning the composition of food and dietary supplements; it is most recognized for the National Nutrient Databa...

Food Reporting Patterns in the USDA Automated Multiple-Pass Method
The objective of this analysis is to describe patterns of food reporting in the AMPM in a nationally representative sample. This analysis uses data from the 2007-2008 What We Eat in America, National Health and Nutrition Examination Survey for males and females ages 12 and older. The step in the AMPM interview where a food is first recalled and reported is determined and assigned a value. These values are summed to create an AMPM reporting score which reflects the use of the five steps in AMPM in the 24- hour dietary intake recall. There are signficant differences in the AMPM reporting score by day of interview, gender, ag...
