Miracle fruit (Synsepalum dulcificum) is native to West Africa, named for its unique ability to transform sour taste into sweet. With the taste modification function, its applications are intriguing, particularly as an alternative sweetener and antioxidant, and for improving the dysgeusia of chemotherapy patients. However, further consumer studies are needed to examine the efficacy of miracle fruit product. The aim of this study was to compare the consumer acceptances of prior miracle fruit administration on different types of sour foods and miracle fruit products.
Methods : 200 healthy volunteers (Women 55%; Whites 23%, Blacks 21%, Asians 24%, Hispanics 27%) aged 18 to 65 years were recruited in New York City. Granny Smith apple, goat cheese, lemonade, plain fat-free yogurt, and cucumber pickle were served with distilled water and a miracle fruit product at 10±1⁰C. One of the following 4 types of dried miracle fruit products were randomly assigned to each panelist. Large Pill (Y); Pill (G); Small Pill (M); Powder (P). Samples’ testing order and miracle fruit product assignment were randomized for each panelist throughout the whole test. The pre and post acceptances for overall, flavor, texture, and aftertaste were evaluated using a 9-point hedonic scale. For post-test, “meeting expectations for corresponding food sample” was also evaluated.
Results : After miracle fruit product application, for yogurt, apple, and goat cheese, all the acceptability values for overall, flavor, texture, and aftertaste increased, while for lemonade and pickle, all the acceptability decreased except for lemonade’s texture acceptability on P product. The pre and post increment differences in overall, flavor, and texture acceptability for yogurt and in overall and flavor acceptability for apple using M product were significantly higher than using other products. For goat cheese, the difference in aftertaste acceptability using P product was significantly higher than using G product.
Conclusions : This study suggests that prior miracle fruit administration when consuming yogurt, apple, and goat cheese is an effective method for improving consumer acceptability. However, the effects of magnitude of acceptability increment may be different by the types of miracle fruit product and food consumed.
