This work aims to encapsulate the fenugreek seed oil (FGSO) to musk the bitter taste as it has various health benefits using maltodextrin and fenugreek mucilage as the wall materials by spray drying. The highest powder yield was 68.23% at 1.5% oil, 2% mucilage, and 10% maltodextrin. The powder moisture content ranged from 4.5 to 6.8%. The bulk density, tapped density, Carr's index and Hausner's ratio was evaluated and the powder showed good flowability. All the peaks obtained by FTIR of powder were similar, and that wavenumber 3,254 cm−1 showed the interaction between the fenugreek mucilage, maltodextrin, and FGSO. XRD revealed that FGSO powder was amorphous and a steep peak found at 20°. TGA showed the two mass losses but was not heat-labile. SEM revealed the particle size and shapes (spherical) for any cracks and fissures. The encapsulation efficiency showed variation from 56.18 to 70.24%. Overall, the results led to the conclusion that fenugreek seed oil can be encapsulated and that the fenugreek seed mucilage can be used as a botanical alternative to maltodextrin as a wall material.
Practical applications
Nowadays, health awareness is increasing among consumers. Due to which the demand for nutraceuticals and functional foods is increasing. Fenugreek seed oil (FGSO) controls chronic diabetes and heart diseases and benefits such as anti-inflammatory and antioxidant properties. The taste of fenugreek seed oil is bitter, so its direct use as oil is restricted. Therefore, encapsulated FGSO with maltodextrin and fenugreek will musk the oil's bitter taste, making it edible. Encapsulation also prevents the degradation of bioactive compounds and increases the shelf life of FGSO. Since it is produced using fenugreek mucilage and maltodextrin, which benefits the gastro-intestinal issue of the consumer. This encapsulated FGSO can be used as a powder for direct use.
