Saccharomyces bailii was isolated from two-thirds of the spoiled mayonnaise and salad dressing samples examined. Most of the rest were spoiled by Lactobacillus fructivorans. However, one sample contained large numbers of both S. bailii and L. plantarum. Two of the spoiled samples also contained small numbers of bacilli. Bacillus subtilis, B. pumilis, B. polymyxa, B. megaterium, and B. lichenifo...

Few studies have been performed to use the detailed healthy eating index (HEI) to estimate consumer demand for diet quality. In this article, we apply household production theory to systematically estimate consumer demand for diet quality using the HEI developed by the U.S. Department of Agriculture. The results show that consumers have insufficient consumption of food containing dark green and...

Stirring olive oil and vinegar to make salad dressing creates an emulsion of vinegar droplets in oil. More vigorous stirring gives smaller droplets, while if left to sit the droplets will begin to coalesce and the two fluids will separate. In this vein, Dodd & Ferrante (J. Fluid Mech., vol. 806, 2016, pp. 356–412) present a new analysis of how homogeneous turbulence in a carrier fluid interacts...

Although the fish-derived, long-chain omega-3 fatty acids (n-3 FA) may be considered “gifts from the sea” for cardiovascular health, the role of the land (or plant) -based n-3 FA -linolenic acid (ALA) has been less clear. ALA is the 18-carbon, 3-double bond (C18:3n-3) precursor to eicosapentaenoic acid (EPA; C20:5n-3) and docosahexaenoic acid (DHA; C22:6n-3), the latter 2 being the predominant ...

The proximate composition, rheology and sensory properties of corn-cocoyam salad cream prepared from varied percentage of corn starch (Cs) and cocoyam starch (Cy) (100Cs, 75Cs: 25Cy, 50Cs:50cy, 25Cs:75Cy and 100Cy) were determined and compared with that of commercial Heinz salad cream. Varied quantities of corn-cocoyam starch in salad cream did not affect the moisture and protein contents of th...

Between 27 January and 7 February 2002, 12 cases of Salmonella Potsdam infection were notified to NSW Health of which nine were residents of the Hunter Health Area. Interviews with two cases notified by two local doctors initiated the investigation and revealed exposure to foods from the same restaurant (restaurant A). All New South Wales S. Potsdam cases, those accompanying cases to restaurant...
