Food Products as Vehicles For n-3 Fatty Acid Supplementation

Abstract

Purpose: An n-3 polyunsaturated fatty acid (PUFA) supplement was incorporated into three food products previously determined to be preferred by cancer patients, and overall acceptability of these foods was evaluated.
Methods: Preliminary testing was performed; an internal panel determined initial acceptability of foods with the supplement added. Taste panel evaluations were held at the Cross Cancer Institute in Edmonton, Alberta. Each participant completed a questionnaire rating aroma, flavour, and overall acceptance on a seven-point hedonic scale (1 = dislike extremely, 7 = like extremely), as well as ability to consume each food daily.
Results: Foods were well-liked by patients and non-patients. Mean ± standard deviation acceptance scores for the three foods were pasta sauce 5.9 ± 0.94 (n = 90), oatmeal 6.1 ± 0.88 (n = 79), and smoothie 5.9 ± 1.12 (n = 126). Overall, 94% of patients and non-patients gave tomato pasta sauce, oatmeal, and the smoothie an acceptance score of at least 5.
Conclusions: The supplement was incorporated successfully into three foods, which were highly accepted by patients with cancer. Further research should focus on incorporating the supplement into flavoured or sweet foods, as these appear most effective. Microencapsulated fish oil in food products may be used as an alternative to fish oil capsules for delivering n-3 PUFA in clinical trials.

Résumé

Objectif: Un supplément d’acides gras polyinsaturés n-3 (AGPI) a été incorporé dans trois produits alimentaires reconnus comme étant les préférés des patients cancéreux, et l’acceptabilité globale de ces aliments a été évaluée.
Méthodes: Un test préliminaire a été effectué; un panel interne a déterminé l’acceptabilité initiale des aliments auxquels on avait ajouté le supplément. Les évaluations du panel de dégustation ont été menées au Cross Cancer Institute d’Edmonton, Alberta. Chaque participant a rempli un questionnaire d’évaluation de l’arôme, de la saveur et de l’acceptation globale sur une échelle hédonique en sept points (1= je n’aime vraiment pas du tout; 7 = j’aime vraiment beaucoup), ainsi que de leur capacité à consommer quotidiennement chaque aliment.
Résultats: Les aliments ont été appréciés par les patients et les non-patients. Les scores d’acceptation moyens ± écart type pour les trois aliments étaient les suivants : sauce pour pâtes 5,9 ± 0,94 (n = 90), gruau 6,1 ± 0,88 (n = 79) et smoothie 5,9 ± 1,12 (n = 126). Dans l’ensemble, 94% des patients et nonpatients ont donné à la sauce aux tomates pour pâtes, au gruau et au smoothie un score d’acceptation d’au moins 5.
Conclusions: Le supplément a été incorporé avec succès dans trois aliments et ces derniers ont été très bien acceptés par les patients souffrant du cancer. Des recherches ultérieures devraient porter sur l’incorporation du supplément dans des aliments aromatisés ou sucrés, qui semblent plus efficaces. De l’huile de poisson microencapsulée peut être utilisée dans les produits alimentaires à titre de solution de rechange aux capsules d’huile de poisson comme source d’AGPI n-3 dans les essais cliniques.
