It is seen that ginger juice might increase the water
content of yogurt and viscous material could be thus diluted
in yogurt; on the other hand, the protein network in yogurt
base might be less disrupted by the addition of the ginger
juice as compared to the control, probably due to decreased
acidity causing incomplete acid gel of casein (19). This has
also been observed in skim milk yogurts with added fruit
preparations, concluding that the polymerization of the
casein might prevent the protein network from disrupting
totally (20).
