Article Synopsis
  • Corn starch-based expanded products were created using a twin-screw extruder with varying concentrations of sugars (fructose, glucose, sucrose, and xylose) integrated at levels of 2% and 10% (w/w) to analyze their effect on expansion properties.
  • The study found that the type of sugar and its concentration, along with the speed of the extruder, significantly influenced the expansion ratios of the extrudates, with fructose at 2% and glucose/sucrose at 10% achieving the best results.
  • FTIR analysis showed no new chemical bonds formed between starch and sugar after extrusion, but sugar's ability to modify melt viscosity improved the overall expansion and texture of the high-fiber

In the next decade, the US anticipates a rapid increase in the older adult population, who also face an increased risk for disease. To reduce this risk, research should explore increasing intake of nutrient-dense foods and prepared meals that include dairy foods and utilize novel food processing that better retain nutrients. This study identified attributes that older adults (age = 65+) desire in dairy-rich ready-to-eat breakfasts and desserts, two meals important in healthy aging.

Previous research has suggested that the impact of smoke affected wines require human evaluation due to in-mouth changes in perception, perhaps associated with saliva. Smoke affected wines ( = 36) from three major wine growing regions in the US were sourced from commercial wineries. A subset of these wines ( = 7) were evaluated by a consumer panel ( = 57) and electronic tongue (e-tongue) to determine the influence of saliva in the sensory profile.

Parental behaviours influence food acceptance in young children, but few studies have measured these behaviours using observational methods, especially among children with Down syndrome (CWDS). The overall goal of this study was to understand parent feeding practices used during snack time with young CWDS (N = 111, aged 11-58 months). A coding scheme was developed to focus on feeding practices used by parents of CWDS from a structured home-use test involving tasting variously textured snack products.

Recently, the use and commercial availability of non-Saccharomyces yeasts (NSY) in winemaking to reduce alcohol content have increased. However, research exploring the influence on sensory quality of the wine, particularly during storage, is limited. Therefore, the objective of this study was to characterize the sensory profiles of Merlot and Chardonnay wines made with pectinase-producing NSY, with added substrate, that is, pectin.

A home-use test (HUT) is one method that provides a measure of ecological validity as the product is consumed in home under common daily use circumstances. One product that benefits from being evaluated in-home are ready-to-eat (RTE) meals. This study determined consumer acceptance of microwave-thermally-pasteurized jambalaya, a multi-meat and vegetable dish from American Cajun cuisine, and a control (cooked frozen jambalaya) through an on-line home-use test (HUT) over a 12-week storage period.

In this study, we estimate consumers' willingness to pay (WTP) for ready meals preserved using microwave assisted pasteurization systems (MAPS)-a novel pasteurization technology, compared to frozen, ready meals. We conducted a laboratory multi-round experimental auction for two samples of ready meal jambalaya in which appearance and sensory evaluation along with extrinsic information was sequentially disclosed to panelists. Our results suggest that when participants tasted the meals and formed an opinion from the meal itself, the liking of appearance and sensory attributes were the most impactful factors for participants' WTP regardless of other available extrinsic (name of the preservation technology and environmental impacts of each technology) attributes.

American craft brewers are targeting barley malt as a novel source of flavor and as a means of differentiation. However, fundamental tools have only recently emerged to aid barley breeders in supporting this effort, such as the hot steep malt sensory method, a wort preparation method recently approved by the American Society of Brewing Chemists for evaluation of extractable malt flavor. The primary objective of this study was to determine if insights into beer liking and sensory attributes can be gained through hot steep malt sensory using an untrained panel of craft beer consumers (n = 95).
