Progress Report Objectives (from AD-416): To identify and quantify the nutrient composition of representative food samples in order to improve and expand the USDA Nutrient Databases. The purpose of this cooperative agreement is to provide quality control, sample preparation and support for USDA-initiated laboratory contracts and other laboratory projects to improve the quality of data in the National Nutrient Data Bank. Approach (from AD-416): The Nutrient Data Laboratory (NDL) is responsible for developing and disseminating authoritative composition databases for foods in the U.S. diet. Foods for preparation and analysis will be selected on the following bases: 1.) Key Foods, i.e. those identified as contributing up to 75% of any one nutrient of public health significance; 2.) foods frequently used as ingredients; and 3.) foods containing components of emerging interest. NDL will develop sampling plans for each type of food sampled, to assure a representative sampling of the food supply. NDL will order samples of food to be delivered to the cooperator for weighing, dissecting for physical components, preparation (including cooking), packaging and shipment to specified analytical laboratories for nutrient analysis. In many cases, the cooperator will need to develop preparation, dissection and cooking protocols. The cooperator will establish procedures for the implementation of these steps and for inclusion of control materials or duplicate samples for quality control assurance. In addition, the agreement includes consultations with NDL and contract laboratories on issues of methodology, sample analysis, handling and storage. The cooperator will also offer expertise in experimental design and interpretation of results of the nutrient analyses. During FY13, NDL procured various meat and poultry. Products at 12 retail locations using the nationwide sampling plan developed for USDA�s National Food and Nutrient Analysis Program (NFNAP). Texas Tech University (TTU) received retail chicken wings and breast to complete an ongoing study of enhanced and non enhanced chicken parts, which began with drumsticks and thighs in FY12. Half of the products were dissected raw and the others were dissected after cooking. The meat and skin were homogenized, composited, and chemically analyzed for proximates, minerals, and cholesterol. Other meats were obtained according to the nationwide NFNAP plan, including bologna, meatballs, rotisserie chicken, and pork loin chops. Samples were cooked where appropriate, dissected, weighed by components (skin, bone, meat, and refuse), homogenized, composited, and chemically analyzed for nutrients named above. Aliquots of the samples along with quality control materials were sent to other laboratories for analysis of other nutrients, as directed by NDL.

During FY12, NDL procured various meat and poultry products from 12 retail locations using the nationwide sampling plan developed for the USDA�s National Food and Nutrient Analysis Program (NFNAP). Texas Tech University (TTU) received 22 whole turkeys for an enhanced turkey study and 8 for a non-enhanced turkey study. Half of the birds were dissected raw and the other half were dissected after roasting. The meat, skin and offal were homogenized, composited, and chemically analyzed for proximates, minerals, and cholesterol. Other meats were obtained according to the nationwide NFNAP plan, including turkey parts, chicken parts, kielbasa sausage, hot dogs, Canadian bacon, and several types of fresh pork sausage. Samples were prepared, homogenized, composited, and chemically analyzed for nutrients named above. Aliquots of the samples along with quality control materials were sent to other laboratories for analysis of other nutrients, as directed by NDL. Also during FY12, TTU was one of the cooperating universities for the Nutrient Data Improvement study, a nationwide beef nutrition project supported by the National Cattlemen�s Beef Association (NCBA). As part of this work, samples of beef loin and round were collected, cuts fabricated, cooked, homogenized, and analyzed for proximates, minerals, and cholesterol. Additional details on the beef study can be found in the report for the project 1235- 52000-061-24T, IMPROVING THE ACCURACY OF BEEF NUTRIENT DATA IN THE USDA NATIONAL NUTRIENT DATABASE FOR STANDARD REFERENCE.

During FY11, Texas Tech University has received bacon samples, both regular and low sodium. The samples were divided for processing either as raw, or after preparation, as cooked (microwaved and pan fried). Homogenized samples were sent to the laboratories as directed by NDL along with quality control materials. Also during FY11, TTU was one of the cooperating universities for the NCBA study of the composition of beef cuts, Agreement number 58-1235-7-0141. As part of this work, samples of beef rib and plate were collected, cuts fabricated, cooked in some cases and homogenized for analysis. Analytical samples were sent to cooperating labs or analyzed by Texas Tech University scientists. The progress of this project was monitored by periodic email and telephone communications.

In addition, the agreement includes consultations with NDL and contract laboratories on issues of methodology, sample analysis, handling and storage. The cooperator will also offer expertise in experimental design and interpretation of results of the nutrient analyses. The current project under this agreement supports the acquisition, preparation, and documentation of various types of meat (e.g., beef, poultry) products for the determination of nutrient content. Nutrient data for meats and poultry in the National Nutrient Database for Standard Reference (SR) require continuous review due to changes in products in the marketplace as well as the introduction of new products. The U.S. food market has experienced increasing demands for prepared, ready-to-eat meat and poultry products leading to an increased availability of these types of products in retail food stores and fast food restaurants. In collaboration with scientists at Texas Tech University, beef and poultry products were sampled nationwide and prepared for analysis. As a result, data for ground turkey and several new beef cuts were released in SR 23. Additional documentation for weights and dissection of food components were generated. The nutrient data in SR are often utilized with nationwide food consumption surveys and the results are used to determine program policies and regulatory decisions within the USDA, EPA, FDA, HHS, and other government agencies. The impact extends beyond the United States to many international databases, including those of Canada and Latin America, adopting the nutrient information in SR as the core of their databases. The USDA Food Safety and Inspection Service, the regulatory arm for food safety and labeling policies for meats, recognizes SR as the authoritative source of nutrient content of meat. SR data are also used by research scientists, dietitians, and the public to obtain current information about U.S. food products and to support the development of healthy meal patterns. With this broad impact, currency of the nutrient composition of meat and poultry is of the utmost importance. Project monitoring is primarily conducted through regular phone and e-mail communication. The collaborating scientists also met with NDL scientists in Beltsville to update project status in July 2010.

Significant Activities that Support Special Target Populations In the National Nutrient Database for Standard Reference (SR), nutrient data on meats and poultry must be continuously updated due to changes in products in the marketplace. The U.S. food market has experienced increasing demands for prepared, ready-to-eat meat and poultry products leading to an increased availability of these types of products in retail food stores and fast food restaurants. In collaboration with scientists at Texas Tech University, beef and poultry products were sampled nationwide and prepared for analysis. As a result several poultry items were just released in SR-22. Additional documentation for weights and dissection of food components were also generated. The nutrient data in SR is often utilized with nationwide food consumption surveys and the results are used to determine program policies and regulatory decisions within other agencies of USDA (such as the Food Safety Inspection Service) , the Environmental Protection Agency (EPA), the Food and Drug Administration (FDA), and other government agencies. Project monitoring is primarily conducted through regular phone and e-mail communication.
