Australian consumers' food-related environmental beliefs and behaviours

The aim of this study was to examine Australians’ food-related environmental beliefs and behaviours. Questionnaires were posted to 500 randomly selected adults, with 223 questionnaires completed (58% response rate). Decreased use of packaging by food manufacturers was viewed as being the most important item to help the environment, while lower meat consumption was seen as least likely to help. Composting food scraps and purchase or consumption of locally produced foods were the most commonly performed food-related environmental behaviours, while use of organic products was the least commonly performed. Moderate consistency (r_s=0.54) was found between reported beliefs and behaviours. Older people were more likely to perform certain food-related environmental behaviours, such as composting. Awareness of the impact on the environment of meat production, organic compared to conventional farming, and food packaging was low even among those who were found to already believe that food-related actions are important to help the environment, suggesting widespread consciousness raising is needed.

Special sauce in sesame seed buns: legal strategy and public policy in the fast-food industry

Lewis Bertly, a top lawyer with leading London law firm LL&B, is retained to defend a case with the potential to change the laws that affect fast-food marketing. Through its Department of Health, the Government of Australia seeks legislation for warning labels on fast-food packaging. To prepare a potential defense against this legal action for McDonald's Bertly is reviewing the history of legal action against the industry in fast-food labeling, nutrition and health. This history is important because the industry's actions through the decades in food nutrition and marketing are likely to be raised as evidence. He also hopes this will help him find a framework to map the way social expectations, a company's innovation, the legal system, and legislation combine to shape an industry. What he learns from this history and especially about the market leader, McDonald's, will inform how the defense approaches this case.

Microbial biosynthesis of biopolymers and applications in the biopharmaceutical, biomedical and food industries

Biopolymers can be produced through a variety of mechanisms. They can be derived from microbial systems, extracted from higher organisms such as plants, or synthesized chemically from basic biological building blocks. A wide range of emerging applications rely on all three of these production techniques. In recent years, considerable attention has been given to biopolymers produced by microbes. It is on the microbial level where the tools of genetic engineering can be most readily applied. A number of novel materials are now being developed or introduced into the market. Biopolymers are being developed for use as medical materials, packaging, cosmetics, food additives, clothing fabrics, water treatment chemicals, industrial plastics, absorbents, biosensors, and even data storage elements. This review identifies the possible commercial applications and describes the various methods of production of microbial biopolymers.
