It is hypothesized that differences in the extent of retro-nasal aroma release during consumption may be 1 of the reasons that people vary in their satiation characteristics. Using real-time atmospheric pressure chemical ionization mass spectrometry (APcI-MS), in vivo retro-nasal aroma release was determined for 30 subjects consuming 9 different food products, varying in physical structure (i.e...

The cultivated strawberry (Fragaria x ananassa Duch.) is an important berry crop worldwide due to its flavourful taste, and high content of nutrients and health-beneficial phytochemicals. Derived from interspecific hybridization of the octoploids F. virginiana and F. chiloensis, a vast number of strawberry varieties have been developed adopted to varying growth environments, and in order to mee...

BACKGROUND American ginseng (Panax quinquefolius L.) and Asian ginseng (Panax ginseng Meyer) products, such as slices, have a similar appearance, but they have significantly different prices, leading to widespread adulteration in the commercial market. Their aroma characteristics are attracting increasing attention and are supposed to be effective and nondestructive markers to determine adulter...

We have shown in molecular basis that alcoholic tea aroma is mainly formed by endogenous enzymatic hydrolysis of glycosidic aroma precursors during manufacturing. Amounts of alcoholic aroma precursor and glycosidase activity in each part of the tea shoot (Camellia sinensis var. sinensis cv Yabukita and a hybrid of var. assamica & var. sinensis cv Izumi) were indirectly measured by means of a cr...

• Aroma variability in truffles has been attributed to maturation (Tuber borchii), linked to environmental factors (Tuber magnatum), but the involvement of genetic factors has been ignored. We investigated aroma variability in Tuber uncinatum, a species with wide distribution. Our aim was to assess aroma variability at different spatial scales (i.e. trees, countries) and to quantify how aroma w...

Methods To date, 54 participants (mean age 58.7, 82% female) were randomized to either: 1) lavender (stress-reducing aroma), 2) coconut (detectable placebo), or 3) water (non-detectable placebo). The detectable placebo group was used to assess aroma-mediated expectancy. Further, half of the participants in each group, along with their aroma, received a prime suggesting they are inhaling a power...

The present study investigated the effect of aroma exposure time and aroma concentration on ad libitum intake and subjective satiation. In a within-subject study, thirty-eight unrestrained, healthy female participants (age: 18-39 years; BMI: 18·5-26·0 kg/m²) were asked to consume tomato soup during lunchtime, until they felt comfortably full. Every 30 s, the participants consumed 10 g of a blan...

We have developed a 3D vision-based semiautonomous assistive robot arm control method, called AROMA-V, to provide intelligent robotic manipulation assistance to individuals with impaired motor control. A working prototype AROMA-V was built on a JACO robotic manipulator combined with a low-cost short-range 3D depth-sensing camera. In performing actual robotic manipulation tasks with the AROMA-V,...

Forty three rice genotypes were used to evaluate their aroma detection through sensory test. Aroma was detected by 1.7% KOH as a sensory test. Thirteen rice genotypes were detected having strong aroma; ten had moderate aroma; fifteen had slight aroma and five had no aroma. In case of grain shape study, 37 genotypes were evaluated as slender and six as medium. In this study, grain aroma had sign...
