- Frozen yogurt (FY) can be fortified with nano-emulsion containing purple rice bran oil (NPRBO).
- NPRBO can influence the structure of the FY.
- NPRBO cannot affect Streptococcus thermophilus and Lactobacillus bulgaricus survival in the FY.
The objectives of this study were to develop and evaluate a frozen yogurt (FY) fortified with a nano-emulsion containing purple rice bran oil (NPRBO). NPRBO with fat droplets size range of 150-300 nm was mixed with the FY ingredients to produce a frozen yogurt containing NPRBO (FYNRO). Plain frozen yogurt (PFY), frozen yogurt with sodium caseinate (FYSC) and FYNRO had similar hardness. The apparent viscosity of the FYNRO mix was similar to the PFY mix with values of 0.19 and 0.17 Pa·s, respectively. The FYNRO micrograph showed a more compact and dense structure compared to FYSC and PFY. This study demonstrated that FY could be fortified with NPRBO.
