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. -

The Impact of Food Viscosity on Eating Rate, Subjective Appetite, Glycemic Response and Gastric Emptying Rate
The Impact of Food Viscosity on Eating Rate, Subjective Appetite, Glycemic Response and Gastric Emptying Rate Yong Zhu1, Walter H. Hsu2, James H. Hollis1* 1 Department of Food Science and Human Nutrition, Iowa State University, Ames, Iowa, United States of America, 2 Department of Biomedical Sciences, Iowa State University, Ames, Iowa, United States of America Abstract Understanding the impact of rheological properties of food on postprandial appetite and glycemic response helps to design novel functional products. It has been shown that solid foods have a stronger satiating effect than their liquid equivalent. However, whether a subtle change in viscosity of a semi-solid food would have a similar effect on appetite is unknown. Fifteen healthy males participated in the randomized cross-over study. Each participant consumed a 1690 kJ portion of a standard viscosity (SV) and a high viscosity (HV) semi-solid meal with 1000 mg acetaminophen in two separate sessions. At regular intervals during the three hours following the meal, subjective appetite ratings were measured and blood samples collected. The plasma samples were assayed for insulin, glucose-dependent insulinotropic peptide (GIP), glucose and acetaminophen. After three hours, the participants were provided with an ad libitum pasta meal. Compared with the SV meal, HV was consumed at a slower eating rate (P = 0.020), with postprandial hunger and desire to eat being lower (P = 0.019 and P,0.001 respectively) while fullness was higher (P,0.001). In addition, consuming the HV resulted in lower plasma concentration of GIP (P,0.001), higher plasma concentration of glucose (P,0.001) and delayed gastric emptying as revealed by the acetaminophen absorption test (P,0.001). -

Seed Dormancy and Preharvest Sprouting in Quinoa (Chenopodium Quinoa Willd)
plants Review Seed Dormancy and Preharvest Sprouting in Quinoa (Chenopodium quinoa Willd) Emma M. McGinty 1, Kevin M. Murphy 2 and Amber L. Hauvermale 2,* 1 The School of Biological Sciences, Washington State University, P.O. Box 644236, Pullman, WA 99164, USA; [email protected] 2 Department of Crop and Soil Science, Washington State University, Pullman, WA 99164, USA; [email protected] * Correspondence: [email protected]; Tel.:+1-509-335-3661 Abstract: Quinoa (Chenopodium quinoa Willd.) is a culturally significant staple food source that has been grown for thousands of years in South America. Due to its natural drought and salinity tolerance, quinoa has emerged as an agronomically important crop for production in marginal soils, in highly variable climates, and as part of diverse crop rotations. Primary areas of quinoa research have focused on improving resistance to abiotic stresses and disease, improving yields, and increasing nutrition. However, an evolving issue impacting quinoa seed end-use quality is preharvest sprouting (PHS), which is when seeds with little to no dormancy experience a rain event prior to harvest and sprout on the panicle. Far less is understood about the mechanisms that regulate quinoa seed dormancy and seed viability. This review will cover topics including seed dormancy, orthodox and unorthodox dormancy programs, desiccation sensitivity, environmental and hormonal mechanisms that regulate seed dormancy, and breeding and non-breeding strategies for enhancing resistance to PHS in quinoa.

Food Allergy
Information Statement Food Allergy The Institute of Food Science & Technology has authorised the following Information Statement, dated January 2009, which cancels and replaces the version dated October 2005. SUMMARY The problem of food allergens is part of a wider problem, that of all kinds of adverse reactions to foods, which can also result from microbial and chemical food poisoning, psychological aversions and specific non-allergenic responses. Food allergy is now recognised as an important food safety issue. Dealing with at least the major serious food allergens is an essential part of Good Manufacturing Practice. The greatest care must be taken by food manufacturers • to formulate foods so as to avoid, wherever possible, inclusion of unnecessary major allergens as ingredients; • to organise raw material supplies, production, production schedules and cleaning procedures so as to prevent cross-contact of products by "foreign" allergens; • to train all personnel in an understanding of necessary measures and the reasons for them; • to comply with the relevant labeling legislation providing appropriate warning, to potential purchasers, of the presence of a major allergen in a product; • to have in place an appropriate system for recall of any product found to contain a major allergen not indicated on the label warning. The purpose of this statement is to describe the nature and cause of food allergies, to outline recent changes in legislation that aim to help allergic consumers to live with their condition and to emphasise the measures that manufacturers and caterers should take to minimise the problems. BACKGROUND Adverse reactions to foods Adverse reactions to foods include not only food allergies but may also result from microbial and chemical food poisoning, psychological aversions, and specific non-allergenic responses. -

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.
