  • ABSTRACT DIXON, ELIZABETH MARIE. Whey Permeate
    ABSTRACT DIXON, ELIZABETH MARIE. Whey Permeate, Delactosed Permeate, and Delactosed Whey as Ingredients to Lower Sodium Content of Cream Based Soups. (Under the direction of Jonathan C. Allen) The use of whey permeates as salt substitutes can help to decrease sodium and chloride intake, increase potassium, calcium and magnesium intakes and decrease hypertension risk. Five different whey permeates from 5 different manufacturers were analyzed with ICP for mineral content (Na, K, Ca, Mg, Fe, Zn). Two permeates are powder and three are liquid. Lactose and protein content were also analyzed by Lactose/D-Glucose UV kit from Roche and BCA protein assay, respectively. Chloride and phosphate were measured spectrophotometrically. Basic tastes and aromas were quantified by a trained sensory panel. Based on the highest “salty taste” identified by the trained sensory panel, one liquid and one solid permeate were further investigated as sodium substitutes. The sodium content of the guideline solutions for comparing salty taste of the permeates were used to calculate the equivalent concentrations of salt and permeate for salty taste in aqueous solution. Two soup formulations were used to test the use of permeate as a salt substitute; one retorted, canned, condensed cream soup base, and one fresh cream soup base. Each formulation of soup was tested on a separate day by 75 consumer panelists who averaged between 20 and 30 years of age. Four samples were given each day 0%, 50%, 100% of the standard salt content in condensed soup, and permeate at a content calculated to be equal in salty taste to the standard salt content.

    March 26, 2010 Carole Davis CoRExecutive Secretary of the Dietary Guidelines Advisory Committee Center of Nutrition Policy and Promotion U.S. Department of Agriculture 3101 Park Center Drive, Room 1034 Alexandria, VA 22303 RE: 2010 Dietary Guidelines for Americans Dear Ms. Davis and the Dietary Guidelines Advisory Committee: The American Meat Institute (AMI) is the nation's oldest and largest meat packing and processing industry trade association. AMI members slaughter and process more than 90 percent of the nation's beef, pork, lamb, veal, and a majority of the turkey produced in the United States. On behalf of AMI and its member companies, we appreciate the opportunity to comment on the 2010 Dietary Guidelines for Americans (or the Guidelines). AMI has and will continue to support the use of sound science as the foundation for nutritional public policy. AMI would like to commend the Dietary Guidelines Advisory Committee (the Committee) for its structured approach in compiling the data, modifying proposed nutritional targets, and working with the food industry in a partnered approach to improve consumer public health. The health of our customers is the driving force in the production of meat and poultry products, not only with respect to improving the safety of meat and poultry products, but also in offering diverse nutritional products to consumers so they can make an educated decision in choosing the food that best fits their personal lifestyle and family needs. The following comments address specific concerns that require further clarification and/or additional consideration prior to finalizing the Guidelines. Sodium Plays an Important Role in Meat Production and Safety Salt or sodium chloride plays a critical role in the production of meat products -- whether used by large commercial processors, local butchers, or even within the consumer’s home -- to improve the flavor, texture, and safety of those products.

  • Artisanal Salt Production in Aveiro/Portugal - an Ecofriendly Process Carolina M Rodrigues1*, Ana Bio1, Francisco Amat2 and Natividade Vieira1,3
    View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Digital.CSIC Rodrigues et al. Saline Systems 2011, 7:3 http://www.salinesystems.org/content/7/1/3 SALINE SYSTEMS REVIEW Open Access Artisanal salt production in Aveiro/Portugal - an ecofriendly process Carolina M Rodrigues1*, Ana Bio1, Francisco Amat2 and Natividade Vieira1,3 Abstract Solar salinas are man-made systems exploited for the extraction of salt, by solar and wind evaporation of seawater. Salt production achieved by traditional methods is associated with landscapes and environmental and patrimonial values generated throughout history. Since the mid-twentieth century, this activity has been facing a marked decline in Portugal, with most salinas either abandoned or subjected to destruction, making it necessary to find a strategy to reverse this trend. It is, however, possible to generate revenue from salinas at several levels, not merely in terms of good quality salt production, but also by obtaining other products that can be commercialized, or by exploring their potential for tourism, and as research facilities, among others. Furthermore, with an adequate management, biodiversity can be restored to abandoned salinas, which constitute important feeding and breeding grounds for resident and migratory aquatic birds, many of which are protected by European Community Directives. The aims of this manuscript are to present a brief overview on the current state of sea salt exploitation in Portugal and to stress the importance of recovering these salinas for the conservation of this particular environment, for the regional economy, the scientific community and the general public. The Aveiro salina complex is presented in detail, to exemplify salina structure and functioning, as well as current problems and potential solutions for artisanal salinas.

  • Facts, Issues, and Controversies in Salt Reduction for the Prevention of Cardiovascular Disease Francesco P
    ARTICLE Facts, Issues, and Controversies in Salt Reduction for the Prevention of Cardiovascular Disease Francesco P. Cappuccio, DSc, FRCP, Simon Capewell, DSc, FFPH Current salt consumption in human societies is now much greater than needed for survival. Furthermore, high salt intake substantially increases blood pressure (BP) in both animals and humans. Conversely, a reduction in salt intake causes a dose- dependent reduction in BP in men and women of all ages and ethnic groups and in patients already on medication. The risk of strokes and heart attacks rises with increasing BP but can be decreased by antihypertensive drugs. However, the majority of cardiovascular disease (CVD) events occur in the numerous individuals with ‘‘normal’’ BP levels below the ‘‘clinically hypertensive’’ level which might trigger drug therapy. Nonpharmacological prevention is therefore the only option to reduce the majority of such events. Reductions in population salt intake consistently reduce the number of subsequent CVD events (with additional benefits for the heart, kidneys, stomach, and skeleton). Indeed, this is one of the most important public health measures for reducing the global CVD burden. The most successful policies involve comprehensive which ideally include population monitoring, health education, and reformulation to reduce the salt content concealed in processed foods (which represent over 75% of daily salt intake). Such population-wide salt reduction policies are generally powerful, rapid, equitable, and cost saving. Inevitably, the food and beverage industries, which profit from marketing salt, will try to oppose such policies. However, public health has triumphed in those countries prepared to consider the necessary levers: regulation, legislation, and even taxation.
