HACCP: A Practical Approach 3rd Edition

HACCP: A Practical Approach 3rd Edition

Haccp A Practical Approach 3Rd Edition

By Sara Mortimore and Carol Wallace

HACCP: A Practical Approach 3rd Edition PDF has been updated to include the current best practice and new developments in HACCP application since the last edition was published in 1998. This book is intended to be a compendium of up-to-date thinking and best practice approaches to the development, implementation, and maintenance of HACCP programs for food safety management. Introductory chapters set the scene and update the reader on developments on HACCP over the last 15 years. The preliminary stages of HACCP, including preparation and planning and system design, are covered first, followed by a consideration of food safety hazards and their control. Prerequisite program coverage has been significantly expanded in this new edition reflecting its development as a key support system for HACCP. The HACCP plan development and verification and maintenance chapters have also been substantially updated to reflect current practice and a new chapter on application within the food supply chain has been added. Appendices provide a new set of case studies of practical HACCP application plus two new case studies looking at lessons learned through food safety incident investigation. Pathogen profiles have also been updated by experts to provide an up-to-date summary of pathogen growth and survival characteristics that will be useful to HACCP teams. The book is written both for those who are developing HACCP systems for the first time and for those who need to update, refresh and strengthen their existing systems.  New materials and new tools to assist the HACCP team have been provided and the current situation on issues that are still undergoing international debate, such as operational prerequisite programs.  All tools such as decision trees and record-keeping formats are provided to be of assistance and are not obligatory to successful HACCP.  Readers are guided to choose those that are relevant to their situations and which they find are helpful in their HACCP endeavors.

Lactoferrin: Natural – Multifunctional – Antimicrobial

Lactoferrin: Natural - Multifunctional - Antimicrobial PDF

Lactoferrin: Natural – Multifunctional – Antimicrobial

Lactoferrin: Natural - Multifunctional - Antimicrobial Pdf

By A S Naidu

Lactoferrin: Natural – Multifunctional – Antimicrobial PDF Book. Illnesses resulting from foodborne pathogens occur at least 6 million times each year and cause an estimated 9,000 deaths. For decades, food microbiologists have developed various effective methods of food protection. However, the constant development of multi-facet food processing technologies and the emergence of potent foodborne pathogens, compromised the efficacy of many antimicrobial interventions. Most technologies also fail to address the problem of bacterial debris remaining on the food surface. Furthermore, some bacteria have the ability to develop resistance to antimicrobial interventions. All such factors contribute to the continuously growing concern of keeping our food safe. Lactoferrin: Natural o Multifunctional o Antimicrobial presents the scientific background on use of this naturally occurring microbial blocking agent as an effective food antimicrobial intervention.

THE SOURCE FOR APPLIED SCIENTIFIC INFORMATION ON LACTOFERRIN AS A NATURAL ANTIMICROBIAL INTERVENTION

Lactoferrin: Natural o Multifunctional o Antimicrobial details microbial blocking technology to protect foods from harmful microbes. Recently, researchers at the Center for Antimicrobial Research, California State Polytechnic University at Pomona found that lactoferrin, when activated, functions as a potent antimicrobial intervention. It protects food by removing harmful bacteria from the surface, and by starving bacteria before they can multiply and produce harmful toxins and it also prevents bacteria from re-attaching to food surfaces. As a result this substance has potential to help the agribusiness and food industry supply safer food products to consumers.

WHY LACTOFERRIN?

Studied for 50 years, lactoferrin is known to have many beneficial biological properties as an integral component of the mammalian innate defense system. Lactoferrin is a broad-spectrum antimicrobial known to inhibit proliferation of bacteria, viruses, fungi, and parasites. Some of its current applications include: dietary supplement, ingredient in infant formula, and a medical treatment to boost the immune system. Because lactoferrin occurs naturally in milk products, it has a long track record of being safely consumed by humans.

Convenient and affordable, lactoferrin could revolutionize the field of food antimicrobial science and technology and the way we protect ourselves from foodborne pathogens.

Meat Animals: Growth and Productivity

Meat Animals: Growth and Productivity PDF

Meat Animals Growth and Productivity

Meat Animals: Growth And Productivity Pdf

By D. Lister

Meat Animals: Growth and Productivity PDF. Dramatic shortfalls in crop production in various regions of the world have led some people to question the relatively inefficient use of cereal grains for feeding meat animals instead of their direct use for human food. There is no doubt, however, that meat offers a nutritionally valuable, attractive and widely accepted food, the world demand for which increases daily. Thus it is not enough simply to condemn the consumption of meat as an irresponsible extravagance; rather it is preferable to examine how the demand for meat can be met most efficiently and effectively, which requires a fundamental enquiry into how meat is ‘grown’. The importance of fat, for instance, both to the growing animal and to the consumer, needs to be established in view of the ‘expense’ involved in its deposition by the animal and the extent to which it is discarded at many points in the chain from the slaughterhouse to the consumer. We were aware that there existed a wealth of information on the physiology of growth which, because of its having been collected as part of investigations in many other disciplines and the inevitable communication gap, had not been incorporated into the science of animal production. Similarly there were principles and teChniques of animal husbandry which, if known in other disciplines, might enable more pertinent questions to be asked. The biochemical and physiological pathways by which animals utilise feed to produce body protein, fat and other components are intriguing problems which are receiving considerable attention.

Meat Preservation: Preventing Losses and Assuring Safety

Meat Preservation: Preventing Losses and Assuring Safety

Meat Preservation Preventing Losses And Assuring Safety

By Robert G. Cassens

Meat Preservation: Preventing Losses and Assuring Safety PDF is written as an integrated and all-encompassing text that includes historical aspects and trends, discussion of basic background information, the evaluation and status of techniques and procedures, and treatments of potential future developments. The latter are particularly important because based on consumer desires, there is a definite trend developing to produce and market meat and meat products that have been subjected to a lesser degree of preservation, yet appear to be fresh and more healthful. Today, there is an intense interest to produce the safest meat possible. The overriding theme of Meat Preservation, provides the understanding of the science of meat and discussion for using known technologies to achieve the goal of safe meat of high quality.

Prof. Cassens has gathered information on the preservation of meat from many sources, and organized the material of this important subject in a highly readable form. Proper preservation of meat is important to prevent economic loss due to spoilage, and to prevent the transmission of foodborne illness. To make the text flow smoothly, references are not cited directly, but are given as general sources.

Meat Preservation will be useful for undergraduates, and also valuable to workers and researchers in meat and animal science, food scientists and technologists, and anyone interested in the preservation of meat and meat products.
