This book was released on 2003 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is growing concern that the free radical scavenging effect of antioxidants added to meats might reduce the antimicrobial effectiveness of ionizing radiation. A study was conducted to determine the effect of vitamin E on the behavior of Listeria monocytogenes and color stability in turkey meat following electron beam irradiation. Raw ground turkey breast meat from birds fed diets containing 0 (control), 50, 100, and 200 IU of vitamin E per kg was inoculated with a 5-strain mixture of L. monocytogenes to give [difference]107 CFU/g. Inoculated samples were irradiated at 0, 0.5, 1, and 2 kGy, and stored aerobically (12 days) or under vacuum (42 days) at 4C̊. L. monocytogenes survivors were determined by plating diluted samples on Modified Oxford Medium (MOX) and counting bacterial colonies on MOX plates after 48h at 35C̊. Meat color was measured using a Hunter Lab colorimeter. Irradiation at 2.0 kGy resulted in [difference]3.5 log reduction of initial numbers of L. monocytogenes. There were no significant differences in D-values for L. monocytogenes in meat irrespective of vitamin E treatment (P>0.05). Also, vitamin E treatments did not affect growth rate of the pathogen in aerobic or vacuum-packaged samples following irradiation (P>0.05). Compared to controls, irradiated meat from birds fed 100 or 200 IU vitamin E demonstrated significant improvement in color stability (Hunter L* and a*-values) during aerobic storage (P

This book was released on 1997 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of off-flavours and odours, loss of Polyunsaturated Fatty Acids (PUFA), fat soluble vitamins and pigments and lower consumer acceptability all result from lipid oxidation of muscle foods (Morrissey et al., 1994). Lipid oxidation is initiated in the membrane bound phospholipids which are susceptible to peroxidation due to their high concentration of long chain PUFA. PUFA are very vulnerable to free radical attack because of their double bond structure (MacPherson, 1994). The lipids in poultry exhibit a higher degree of unsaturation than red meats due to a relatively high concentration of phospholipids (Igene and Pearson, 1979). Therefore, poultry meat and meat products are very susceptible to oxidative deterioratioin with oxidation often determining the shelf life of poultry meat products. Vitamin E is located in cell membranes where it's main function is to scavenge free radicals formed during the oxidation of unsaturated fatty acids (Machlin, 1991). It is generally accepted that the stability of muscle fats improves proportionally to the dietary vitamin E dose (Franchini et al., 1990) Dietary vitamin E results in an increase in the stability of poultry meat (Sheehy et al., 1993b). The oxidative stability of chicken meat is greater than that of turkey although the fatty acid composition of the two species is reported to be similar (Marusich et al., 1975). The difference in oxidative stability primarily arises because turkeys have a lower ability to accumulate vitamin E in their tissues than chickens (Sklan et al., 1982). Thus, turkeys require higher dietary concentrations of vitamin E for a longer time period than other species, to achieve effective protection against lipid oxidation. Most of the previous studies on vitamin E supplementation in turkeys have examined the effect of moderate supplementation for a relatively short length of time. The objective of the present study were to determine the effects of high dietary vitamin E on; tissue levels; the susceptibility of raw and cooked leg and breast meat to lipid oxidation and colour deterioration in overwrapped and vacuum packs. Also, to compare endogenous v's exogenous addition of vitamin E on these meat quality characteristics.

This book was released on 2009-09-23 with total page 376 pages. Available in PDF, EPUB and Kindle. Book excerpt: The increased emphasis on food safety during the past two decades has decreased the emphasis on the loss of food through spoilage, particularly in developed co- tries where food is more abundant. In these countries spoilage is a commercial issue that affects the pro?t or loss of producers and manufacturers. In lesser developed countries spoilage continues to be a major concern. The amount of food lost to spoilage is not known. As will be evident in this text, stability and the type of spoilage are in?uenced by the inherent properties of the food and many other factors. During the Second World War a major effort was given to developing the te- nologies needed to ship foods to different regions of the world without spoilage. The food was essential to the military and to populations in countries that could not provide for themselves. Since then, progress has been made in improved product formulations, processing, packaging, and distribution systems. New products have continued to evolve, but for many new perishable foods product stability continues to be a limiting factor. Many new products have failed to reach the marketplace because of spoilage issues.

Download or read book Recent Developments in High Pressure Processing of Foods written by Navin K Rastogi and published by Springer Science & Business Media. This book was released on 2013-07-16 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Features a Foreword by Dr. Dietrich Knorr. Fruit processing and preservation technologies must ensure fresh-like characteristics in foods while providing an acceptable and convenient shelf life, as well as assuring safety and nutritional value. Processing technologies include a wide range of methodologies to inactivate microorganisms, improve quality and stability, and preserve and minimize changes of fresh-like characteristics in fruit. High pressure as a food preservation technique inactivates microorganisms at room temperature or lower; thus, sensory and nutritional characteristics can be maintained. In recent years, a significant increase in the number of scientific papers in literature demonstrating novel and diversified uses of high pressure processing indicates it to be highly emerging technology. The effect of high pressure technology on the quality and safety of foods will be discussed. Selected practical examples in fruits and vegetables, dairy and meat industries using high pressure will be presented and discussed. A brief account of the challenges in adopting this technology for industrial development will also be included.

Available in PDF, EPUB and Kindle. Book excerpt: There is little doubt that today’s food industry is faced with a rapidly changing market landscape. The obvious need to continue to provide consumers with nutritious, delectable, safe, and affordable food products which are also profitable for food manufacturers, as well as the ongoing challenge of ensuring the delivery of adequate nutrition to hundreds of millions of disadvantaged people around the world, appears – at least as much as, if not more than, ever – to be at odds with the challenges posed by soaring energy and food commodity prices; fast-paced changes in consumer demographics, habits, and preferences; and the continual need to stay ahead of current and emerging food safety issues. In addition to this, the present ubiquity in the industry of terms such as functional foods, nutraceuticals, low sodium, low fat, clean label, minimal processing, and natural – to name a few – underscores yet a different dimension of the challenges faced by food processors today. On the other hand, however, the solutions of many of these challenges may, concurrently, present the food industry with unique and exciting opportunities. The processed meat industry, despite its long history and tradition, is certainly not exempt from having to face these modern challenges, nor excluded from realizing the promises of the opportunities that may lie ahead.
Download or read book Lipid Oxidation written by Edwin N. Frankel and published by Elsevier. This book was released on 2014-01-23 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this second edition, Edwin Frankel has updated and extended his now well-known book Lipid oxidation which has come to be regarded as the standard work on the subject since the publication of the first edition seven years previously. His main objective is to develop the background necessary for a better understanding of what factors should be considered, and what methods and lipid systems should be employed, to achieve suitable evaluation and control of lipid oxidation in complex foods and biological systems. The oxidation of unsaturated fatty acids is one of the most fundamental reactions in lipid chemistry. When unsaturated lipids are exposed to air, the complex, volatile oxidation compounds that are formed cause rancidity. This decreases the quality of foods that contain natural lipid components as well as foods in which oils are used as ingredients. Furthermore, products of lipid oxidation have been implicated in many vital biological reactions, and evidence has accumulated to show that free radicals and reactive oxygen species participate in tissue injuries and in degenerative disease. Although there have been many significant advances in this challenging field, many important problems remain unsolved. This second edition of Lipid oxidation follows the example of the first edition in offering a summary of the many unsolved problems that need further research. The need to understand lipid oxidation is greater than ever with the increased interest in long-chain polyunsaturated fatty acids, the reformulation of oils to avoid hydrogenation and trans fatty acids, and the enormous attention given to natural phenolic antioxidants, including flavonoids and other phytochemicals.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Non-typhoidal Salmonella spp. are estimated to cause 93.8 million cases of acute gastroenteritis and 155,000 deaths globally each year, approximately 85% of which are estimated to be foodborne, establishing Salmonella as having a significant public health and economic impact on society. Pork products are among the top food-borne sources of Salmonella globally, while beef products have been implicated in several large outbreaks in recent years. Contamination of beef and pork with Salmonella can also have a negative impact on the agri-food and trade sectors due to costly recalls of products and by limiting market access. FAO and WHO have undertaken a systematic review of the available evidence on interventions to control Salmonella in beef and pork from primary production through processing. This information was then considered by an expert meeting which provided recommendations on efficacious interventions. This report presents the outcome of those deliberations as well as the review of studies on which the discussions were based, providing the reader with a wealth of up to date information on the currently available interventions for the control of Salmonella in beef and pork."--Publisher's description.
