formulating gluten-free products with proteins from egg white may improve the volume of bread and enhance the overall product, suggests new research. researchers from the ohio state university report in food chemistry that including egg white solids in gluten-free dough formulated with hydroxypropyl methylcellulose (hpmc) produced bread with enhanced loaf volume. led by rachel crockett, the researchers note that levels of egg white solids needed to exceed 15 per cent in order to overcome potential negative interactions between the egg-derived ingredients and hpmc.

spanish researchers analysing a cake-manufacturing facility found that non-food contacts areas such as the floor are a breeding ground for listeria monocytogenes (lm), and that the pathogen can remain in such areas post sanitation. the authors, writing in food control , argue that identification of lm survival points could be of value in terms of optimising pathogen control as part of a haccp programme.

freeze-dried salmon could be the latest thing among health-conscious astronauts and military types and mountain climbers, thanks to work at the university of alaska fairbanks (uaf). researchers have devised a process that removes around 97 per cent of the moisture from salmon while preserving qualities such as taste and colour. the product is also quick to hydrate and can be stored at room temperature.

chewing gum reduces cravings for sweet and salty snacks in between meals, and could aid appetite control, according to researchers. this study, which was funded, in part, by the wrigley science institute and published in the journal appetite, concludes that chewing gum for at least 45 minutes suppresses hunger, appetite and cravings for snacks as well as promoting fullness. the authors, based at the institute of psychological sciences at the university of leeds said that their study demonstrated that in “participants who are moderately restrained eaters, who are motivated to lose weight or maintain weight loss, chewing gum reduced desire for and intake of highly palatable sweet and salty snacks.
