Purpose: To increase the availability of Korean sweet potato (SP), the quality characteristics of the sweet potato pastes (SPPs) and rice madeira cake (RMC) using them were investigated.
Methods: Ten different SPPs, orange fleshed Sinwhangmi, Juwhangmi, purple fleshed Sinjami and Yeonjami, Cream fleshed Sinyulmi, Sinchunmi, and newly developed Geonwhangmi, Dahomi, Daeyumi, and Pongwonmi were used. Their pastes were prepared by washed, peeled, steamed, crushed, vacuum packed and stored in a freezer until use.
Results: The SPPs and RMC with them were significant difference from different cultivars with color value, rheology and texture properties, and preference test. The SPP showed the highest lightness value in Sinchunmi (55.89) and the highest viscosity in Geonhwangmi (55.33 poise). The RMCs with SPPs had lower values in hardness and chewiness than the RMC without SPP. Overall quality of preference test showed the highest values in RMC with Sinyulmi and Sincheonmi.
Conclusion: The best quality of sweet potato shaped rice madeira cake was made using Sinyulmi and Sinchunmi pastes. It is suggested that sweet potato paste is possible to use as the biomaterials for application of processed foods.
