Plastics are now being used on a large scale for the packaging of fatty and aqueous foodstuffs and beverages, both alcoholic and non-alcoholic. This is evident for all to see on the supermarket shelves, margarine is packed in polystyrene tubs, beer is packed in PVC bottles and meats and bacon in shrink-wrap film. Foods are also increasingly being shipped in bulk, in plastic containers. Additionally, there is the area of use of plastics utensils, containers and processing equipment in the home and during bulk preparation of food in producing factories, at home and in restaurants and canteens. Thus it is likely that some transfer of polymer additives will occur - adventitious impurities such as monomers, oligomers, catalyst remnants and residual polymerisation solvents and low molecular weight polymer fractions - from the plastic into the packaged material with the consequent risk of a toxic hazard to the consumer.The actual hazard arising to the consumer from any extractable material is a function of two properties, namely, the intrinsic toxicity of the extracted material as evaluated in animal feeding trials (not dealt with in this book) and the amount of extracted from the polymer which enters the packed commodity under service conditions, that is, during packaging operations and during the shelf life of the packaged commodity at the time of the consumption. This book covers all aspects of the migration of additives into food and gives detailed information on the analytical determination of the additives in various plastics. It will be of interest to those engaged in the implementation of packaging legislation, including management, analytical chemists and the manufacturers of foods, beverages, pharmaceuticals and cosmetics and also scientific and toxicologists in the packaging industry.
Since Consumers' Research Magazine's inception in 1928, readers have been given reliable and useful information on food issues. Characteristically, much of the information had been provided far in advance of official concern or public awareness. Thus, you will find a discussion of E. coli 0157:H7 printed in May 1991 - several years prior to the publicized incident in a fast food restaurant that affected many children. Information on the newly banned pesticide Alar was printed in November 1985, and the possible association between carrageenan and ulcerative colitis appeared as early as May 1972. These, and many other topics included in this anthology, appeared years prior to official recognition that these food issues posed public health problems. Every article included in this book can enlighten you as a consumer, in order to make intelligent choices in a bewildering marketplace.
This is good food with strong nutritional value, for people whose cookery skill is NIX. Fresh food is much cheaper to buy and can eat like you're in TGI Friday, your local Curry House or Trattoria.
The author takes you through his journey of becoming a Restaurant owner and Chef. He details how to start the process, do the research and build the knowledge needed to feel confident enough to take the first steps with straight forward time proven procedures that kept his first restaurant going for more than 12 years. He talks about mistakes as well. This is a must read for all people who have heard from family and friends, "You should open a restaurant" and have seriously thought about it!
Recent advances in array-based detectors and imaging technologies have provided high throughput systems that can operate within a substantially reduced timeframe and other techniques that can detect multiple contaminants at one time. These technologies are revolutionary in terms of food safety assessment in manufacturing, and will also have a significant impact on areas such as public health and food defence. This book summarizes the latest research and applications of sensor technologies for online and high throughput screening of food.
The book first introduces high throughput screening strategies and technology platforms, and discusses key issues in sample collection and preparation. The subsequent chapters are then grouped into four sections: Part I reviews biorecognition techniques; Part II covers the use of optical biosensors and hyperspectral imaging in food safety assessment; Part III focuses on electrochemical and mass-based transducers; and finally Part IV deals with the application of these safety assessment technologies in specific food products, including meat and poultry, seafood, fruits and vegetables.
