The brewery industry generates waste that could be used to yield a natural extract containing bioactive phenolic compounds. We compared two methods of purifying the crude extract-solid-phase extraction (SPE) and supercritical fluid extraction (SFE)--with the aim of improving the quality of the final extract for potential use as safe food additive, functional food ingredient, or nutraceutical. T...

Epidemiological studies have consistently shown that regular consumption of fruits and vegetables is strongly associated with reduced risk of developing chronic diseases, such as cancer and cardiovascular disease. It is now widely believed that the actions of the antioxidant nutrients alone do not explain the observed health benefits of diets rich in fruits and vegetables, because taken alone, ...

Exposure to non-nutritional food additives during the critical development window has been implicated in the induction and severity of behavioural disorders such as attention deficit hyperactivity disorder (ADHD). Although the use of single food additives at their regulated concentrations is believed to be relatively safe in terms of neuronal development, their combined effects remain unclear. ...

The objective of this study was to evaluate the efficacy of plant essential oils (EOs) in combination and to investigate the effect of food ingredients on their efficacy. The EOs assessed in combination included basil, lemon balm, marjoram, oregano, rosemary, sage and thyme. Combinations of EOs were initially screened against Bacillus cereus, Escherichia coli, Listeria monocytogenes and Pseudom...

Coumarin as an additive or as a constituent of tonka beans or tonka extracts is banned from food in the United States due to its potentially adverse side effects. However, coumarin in food from other natural ingredients is not regulated. "True Cinnamon" refers to the dried inner bark of Cinnamomum verum. Other cinnamon species, C. cassia, C. loureiroi, and C. burmannii, commonly known as cassia...

Carrageenan (CGN) has been used as a safe food additive for several decades. Confusion over nomenclature, basic CGN chemistry, type of CGN tested, interspecies biology, and misinterpretation of both in vivo and in vitro data has resulted in the dissemination of incorrect information regarding the human safety of CGN. The issue is exacerbated when mechanistic data obtained from in vitro experime...
