Abstract:
The study aimed at studying the results of the amount of black sesame and types of sweetener
replacement such as stevia and sucralose on the sensory quality, physical quality, the nutrition
property and the customers satisfaction. The three recipes of black sesame egg custard sauce
with the proportion of 5, 10 and 15 % were set. The sensory evaluation result showed that the
scores of the sensory quality in terms of colors, tastes, and preferences were higher in black
sesame egg custard sauce with the proportion of 10 % than the ones with 5 % and 15 %.
Stickiness and color value (a*) signifi cantly increased, while color value (L*) signifi cantly
decreased (p ≤ 0.05) with increasing the proportions of black sesame. Also, the results from
the two types of the sweetener replacements, namely sucralose and stevia, showed that the
10 % black sesame egg custard sauce with sucralose was more popular among the panelist
than the black sesame egg custard sauce with stevia in terms of the sweetness, and the overall
preferences were signifi cantly diff erent (p ≤ 0.05). However, stickiness value (L* a* b*) was
not signifi cantly diff erent (p ≤ 0.05). The results regarding to its nutrition property revealed
that black sesame egg custard sauce with sucralose contained nutrition property in terms of
calories, fat, carbohydrate, protein, dietary fi ber, moisture, ash, total sugar, calcium, iron, and
phosphorus (200.33 Kcal, 13.33 g, 12.76 g, 7.33 g, 5.05 g, 64.98 g, 1.60 g, 4.05 g, 394.57 mg,
1.57 mg and 218.15 mg). The results of the customers satisfaction revealed that the participants
accepted the product in a high acceptance level. 90 % of them would buy the product if it were
launched into the market and 45 % stated that the product could be considered as healthy products.
