Nutritional Quality Changes of Cooked Beef Due to Refrigeration Storage
IOSR Journal of Environmental Science, Toxicology and Food Technology (IOSR-JESTFT) e-ISSN: 2319-2402,p- ISSN: 2319-2399.Volume 11, Issue 10 Ver. IV (October. 2017), PP 49-56 www.iosrjournals.org Nutritional Quality Changes of Cooked Beef Due to Refrigeration Storage *Md. NannurRahman,HabiburRahman, Rokeya Begum,Shafiul Islam; Abdur Rahim Department of Food Technology and Nutritional Science,MawlanaBhashani Science and Technology University, Santosh, Tangail-1902, Bangladesh Corresponding Author: *Md. NannurRahman Abstract: This study was undertaken to assess nutritional quality of cooked beef stored at refrigeration (4±1⁰C) for 1 day, 3 days, and 5 days. A traditional method was used to cook the collected beef and subjected to analyze proximate composition, peroxide value (PV), total volatile base nitrogen (TVBN), bacteriological load and sensory quality. The moisture percentage of fresh cooked, 1 day, 3 days, and 5 days storage samples were 78.03, 65.78, 63.58, and 63.02 respectively. There was no significant difference (P >0.5) in ash content with increasing time in refrigeration. The percentage of fat content in all the samples was almost same (6.94 ± 0.05) and showed a declining trend. The content of protein was found to be increased significantly (p>0.05)from fresh cooked beef to 5 days storagesamples. The PV in 5 days storage sample was 7.5 meq/kg fat indicates slight rancidity whereas other samples showed the value around 2 meq/kg. The TVBN content in fresh, 1 day, and 3 days storage samples was found to be (17 ± 2.6) mg/100gm while in 5 days storage samples it was increased to 36.4 mg/100gm protein.The fresh cooked beef was free from bacterial contamination whereas 1 day, 3 days, and 5 days storage samples recovered5.8 x 105, 7.8 x 105 and 8.8 x 105 (CFU/g).The sensory attributes of cooked beef showed a declining trend with increasing the storage period. -

Master of Public Health/Master of Science in Nutrition Dual Degree Proposal (Plan B, Non-Thesis Requiring) Document of December
Master of Public Health/Master of Science in Nutrition Dual Degree Proposal (Plan B, non-thesis requiring) Document of December 8, 2014; Revised February 2, 2015 This is a dual degree program that is offered jointly by the Departments of Epidemiology and Biostatistics, and Nutrition. The core Master Degree courses include a mixture of those from nutrition, biochemistry and public health. 1. Background and Justification The World Health Organization, (WHO), identifies diet and nutrition as a lifestyle factor critical for maintenance of health and well-being, as well as a factor influencing risk of chronic disease. Cardiovascular disease, diabetes, cancer and obesity are examples of chronic diseases significantly related to diet and nutrition. Obesity is one of the most common conditions and is growing to epidemic proportions. The two most common associated co-morbidities of obesity, type 2 diabetes and hypertension, are highly prevalent health risks and are among the principal causes of death in the general population. Additionally, in third world countries, malnutrition is a very common cause of infection or death, especially in young children. Accordingly, knowledge of the basic elements of good nutrition and the biochemical pathways associated with the metabolism of protein, fat and carbohydrate offers important contributions to mitigate these health problems. The proposed dual degree program will provide the student with a core understanding of the mechanics of metabolism combined with advanced courses in public health and nutrition. This combined approach will yield a highly qualified and competitive public health practitioner trained to develop evidence based policy, programs, strategies and advocacy to address these health risks and problems. -
Can This Natural Sweetener Lower Blood Sugar?
Can This Natural Sweetener Lower Blood Sugar? Analysis by Dr. Joseph Mercola Fact Checked STORY AT-A-GLANCE - Sugar is a carbohydrate, but most of the allulose you consume is excreted by the kidneys before it is metabolized, leaving you with few calories. It may also help lower your blood sugar Sucrose (white table sugar) and high-fructose corn syrup (HFCS) are two of the more common sweeteners derived from plant sources; both negatively affect metabolism, but HFCS has signicantly worse effects than white sugar HFCS is cheaper and 20% sweeter than sugar, and thus more cost effective for food manufacturers. The FDA recently exempted allulose from being listed as an added sugar in processed foods Articial sweeteners like Splenda may lower your gut bacteria, increase your intestinal pH and accumulate in fat cells; Splenda is linked to leukemia and aspartame (Nutrasweet) is linked to insulin intolerance Many people have a sweet tooth. For some, it can become an addiction,1 fueled by a food industry that continually creates an abundance of highly palatable, inexpensive, ultraprocessed foods. As some companies cash in on a market for lab-created, low- calorie sweeteners, one natural sweetener may help curb your sweet tooth without raising your blood sugar. In fact, it may have the opposite effect. While manufacturers seek out “perfectly engineered food,”2 the incidence of obesity3 and obesity-related health conditions4 has skyrocketed. Type 2 diabetes is one of the obesity-related conditions that has a signicant impact on many of your bodily systems. People with diabetes have a higher risk of also having heart disease, stroke, glaucoma, kidney disease and high blood pressure.5 It would make sense if the incidence of diabetes and obesity goes down, you could have a positive impact on these conditions that contribute to at least ve of the top 10 leading causes of death.6 The obesity epidemic is one of the most important global public health challenges. -

During processing and storage of berry products containing added sucrose, sucrose is inverted to glucose and fructose. We have previously shown that postprandial glycaemic response induced by intact sucrose is attenuated when sucrose is consumed with berries rich in polyphenols. It is not known how inversion of sucrose affects glycaemic response. We investigated postprandial glycaemic and insu- linaemic responses to blackcurrant (Ribes nigrum) and lingonberry (Vaccinium vitis-idaea) nectars and a reference drink (water) sweetened with glucose and fructose, representing completely inverted sucrose. The nectars and reference drink (300 ml) contained 17·5 g glucose and 17·5 g fructose. Polyphenol composition of the nectars was analysed. A total of eighteen healthy volunteers participated in a randomised, controlled, cross-over study. -

A Review on Impacts of Genetically Modified Food on Human Health
The Open Nutraceuticals Journal, 2011, 4, 3-11 3 Open Access A Review on Impacts of Genetically Modified Food on Human Health Charu Verma1, Surabhi Nanda2, R.K. Singh3, R.B. Singh4 and Sanjay Mishra1,2,* 1Department of Biotechnology & Microbiology, Institute of Foreign Trade & Management, Lodhipur Rajput, Delhi Road, Moradabad 244001, U.P., India 2Department of Biotechnology, College of Engineering & Technology, IFTM Campus, Lodhipur Rajput, Delhi Road, Moradabad 244001, U.P., India 3Kumaon Engineering College, Dwarhut, Uttarakhand Technical University, Dehradun, Uttarakhand, India 4Halberg Hospital & Research Center, Civil Lines, Moradabad 244 001, U.P., India Abstract: Biotechnology offers a variety of potential benefits and risks. It has enhanced food production by making plants less vulnerable to drought, frost, insects, and viruses and by enabling plants to compete more effectively against weeds for soil nutrients. In a few cases, it has also improved the quality and nutrition of foods by altering their composition. However, the use of biotechnology has also raised concerns about its potential risks to the environment and people. For example, some people fear that common plant pests could develop resistance to the introduced pesticides in GM crops that were supposed to combat them. Genetic engineering provides a means to introduce genes into plants via mechanisms that are different in some respects from classical breeding. A number of commercialized, genetically engineered (GE) varieties, most notably canola, cotton, maize and soybean, were created using this technology, and at present the traits introduced are herbicide and/or pest tolerance. Gene technology enables the increase of production in plants, as well as the rise of resistance to pests, viruses, frost, etc.
