Sensory evaluation of rice fortified with iron

Your Account Logout. Sensory Evaluation Techniques. By Morten C.

Thus, in the present study, the UR rice fortified with ferric pyrophosphate presented a differentiated texture, more moist, which does not interfere with consumer acceptance. The results suggest that the differences between the conventional and fortified cereals were minimal since less than half of the panelists detected differences, results similar to those found in the Duo-Trio Test used in the present study.

In a different study by Moretti et al. Four local recipes were tested along with cooked and uncooked rice.

The panel was composed of 24 middle-class Indian women. The subjects were blindfolded.

The results demonstrated that the fortified and unfortified uncooked rice were indistinguishable. Similarly, in the cooked recipes, meals containing the fortified rice were indistinguishable from the meals containing unfortified rice.

A limitation to this study was the failure to implement the Acceptance Test in individual booths. The evaluation of samples was conducted in rooms reserved at the community centers, which represented partly controlled environments, that is, with no physical separation between the panelists.

These conditions may have created the opportunity for communication between the participants or other forms of influence on the result. Another limitation was the inclusion of subjects that had less than four years of education, which made it difficult to use the hedonic scale adapted for the Acceptance Test. Thus, according to the profile of the panelists, the Facial Hedonic Scale would have been better adequate for this study. Moreover, rice used as a vehicle for fortification of iron can represent an important alternative to enriched foods since it is deeply rooted in the population's daily dietary culture and eating habits in addition to being widely accessible and affordable by all socio-economic levels of society.

Finally, further studies are needed to better evaluate consumer acceptability tests and the bioavailability of this important and widely consumed food in rice-eating populations.

Acknowledgements The authors are grateful to the School of Nursing and Nutrition at the Federal University of Minas Gerais for allowing us to conduct part of this study at their dietary laboratory; the Health Secretary of the City of Vespasiano for authorizing us to conduct the study in their community, and they are specially grateful the volunteers for their participation during this study.

The course considers the impact of issues such as questionnaire design, expectation and context before reviewing both qualitative methods, e. We reflect upon emotional response and the methods used to capture this, before moving on to more advanced approaches such as Repertory Grid, Conjoint analysis and a review of the techniques available in the Preference Mapping toolbox. By the end of this course delegates should be able to: Define the factors shaping consumer acceptance Review the methods available for determining consumer acceptance and attitudes and their pros and cons Demonstrate how these principles can be utilised for improved NPD New Product Development 5.

Food Flavour April The Food Flavour short course is a four day long programme that introduces the fundamental science of food flavour through relevant scientific case examples and industrially relevant applications.

Both analytical chemistry and flavourist style approaches will be taken to explore how flavour and flavours can be generated, analysed, delivered and commercially exploited. The course is particularly relevant to developing scientists in the food, drink or flavour industry and to students who wish to broaden their experience and subsequently enter the food industry.

The practical element is usually carried out at the place of work.
