Description The coconut whey (CW) (underutilized by-product of virgin coconut oil production, with 2–3% protein)
was subjected to ultrafiltration for concentration of protein
and sugar removal prior to spray drying. The process
parameters of ultrafiltration were standardised with respect
to transmembrane flux, protein retention efficiency and
removal of sugar by using 300 kDa membrane cut off, feed
pH 4 and 2 bar transmembrane pressure at temperature
25 ± 2 C. The protein content was found to increase in
the retentate after ultrafiltration (termed as concentrated
coconut whey, CCW) (from 21 to 46%, w/w) and sugar
content to reduce (from 59 to 34%, w/w). The color
lightness (L*) values of the CW and CCW powders
obtained by spray drying were found to be 83.81 ± 0.33
and 80.70 ± 0.47, respectively. Both the samples of
coconut protein powders were found to be microbiologically safe having water activity index for CCWP of 0.27
and CWP of 0.26. Carr index values for CCW (32.95) and
CW (33.14) powders indicate both of them to have fair
flowability. The powders have high potential as new source
of protein or as a functional ingredient in the food processing industries.
