BACKGROUND Recent evidence suggests that a lower extent of the retronasal aroma release correspond to a higher amount of ad libitum food intake. This has been regarded as one of the bases of behavioral choices towards food consumption in obese people. In this pilot study we investigated the hypothesis that saliva from obese individuals could be responsible for an alteration of the retro-nasal a...
To limit the impact of food on health issues as obesity, hypertension, or coronary diseases, the reduction of salt or fat content in food products without modifications of organoleptic properties remains a real industrial challenge. A better understanding of the mechanisms involved in release and perception could lead to a better formulation of diet dairy products. In this context, model dairy ...
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...
The paper describes a mechanistic mathematical model for aroma release in the oropharynx to the nasal cavity during food consumption. The model is based on the physiology of the swallowing process and is validated with atmospheric pressure chemical ionization coupled with mass spectrometry measurements of aroma concentration in the nasal cavity of subjects eating flavored yogurt. The study is c...
A headspace sampling method is described for concentrating milk volatiles onto a multi-channel open tubular silicone rubber trap (MCT) for thermal desorption into a GC-FID. Sections of the chromatographic profile, single peaks or combinations of compounds are recaptured with secondary MCTs during a subsequent run. The recaptured aroma is released in a controlled manner by heating the MCT in a p...
We have developed a new methodology for measuring aroma release by coupling together two high performance instruments, proton-transfer-reaction mass spectrometer and closed-cell pressure-controlled rheometer. In this article we report the from aqueous solutions as function of different agitation levels, in connection with theoretical model transfer across interfaces. Two aspects are described m...
Aroma recovery as determined by solid phase microextraction-gas chromatography-mass spectrometry (SPME-GC-MS) was compared in coffees resulting from conventional grinding processes, and from wet grinding with cold and hot water. Freshly roasted coffee as well as old, completely degassed coffee was ground in order to estimate the relationship of internal carbon dioxide pressure in freshly roaste...
Aim The complex aromas of cocktails provide a unique and interesting model system to evaluate the effects of alcohol matrix and aroma-aroma interactions on human aroma perception and partitioning and release of aroma compounds. Here, we study the interactions that occur in an Old-Fashioned cocktail when different types of whiskeys are mixed with different styles of bitters. Methods The interact...
