Microencapsulated supercritical carbon dioxide extract of small cardamom enriches the nutraceutical value of custard
Sayantani Dutta, Paramita Bhattacharjee
The spray dried α-amylase-assisted supercritical carbon dioxide (SC-CO2) extract of small cardamom (rich in 1,8-cineole) was used for the fortification of custard to obtain a new designer nutraceutical custard. The encapsulate was employed at concentrations of 4%, 4.5% and 5% (w/w) to formulate the custards. Custard formulated with 4.5% of encapsulate was most preferred by the sensory panel. This custard sample showed a more stable texture, higher phytochemical properties and lower microbial load than the control sample (formulated without encapsulate). This is the first study on the formulation of a new designer nutraceutical custard by fortification with encapsulated SC-CO2 extract of small cardamom. The processes described here can safely be employed in the development of other nutraceutical or functional foods, which inevitably involves the loss of the phytochemicals of food constituents during manufacture.
